Aditya Birla Group, Lotus Renewables to launch $100m clean energy fund Aditya Birla Group along with Lotus Renewables is set to launch a $100 million Global Clean Energy Fund targeted at developing countries in Asia, including India, as well as Australia. “Currently we are looking Asia and Australia as a market to start with .

We have identified markets like India, Srilanka, Australia, Indonesia, Thailand, Philippines, Vietnam etc,” K Gowri Shankar, Director, Lotus Renewables told DEALSTREETASIA

T

he Global Clean Energy Fund, which will be managed

by Singapore-based Aditya Birla Sun Life Asset Management Company Pte Ltd, will invest in assets that generate clean energy. It will provide debt and equity financing to small and medium-sized clean energy projects across the globe.

The fund will typically work on a pipeline of projects seeking investment pre-construction in sectors such as small hydro, solar, wind, biomass, geothermal, energy storage and smart grids. It will also look at investing in distressed assets that suit its portfolio profile.

The vehicle will have strategic partners in the regions they are targeting. “We will appoint an independent local consultants for doing due- diligence before our investment committee’s evaluation,” said Shankar The fund is expected to make its first close at $30 million in the next two months with the target of closing the $100 million fund by the end of December, he added. Lotus Renewable Energy Group is a multinational renewable energy company with its operations across

India, Sri Lanka, Singapore and Australia. It provides Solar photovoltaic solutions and also owns and runs mini Hydro power plants.

The company will be putting an initial investment of $5 million, said Shankar. “We are targeting clean energy assets that can generate long term consistent return. We are targeting $ return of above 8 %,” he added. With governments turning their focus to renewable energy, the sector has also caught the fancy of investors.It was recently reported that CDC Group Plc, the UK government’s development finance institution, is planning to set up its own renewable energy platform focussed on east India and neighbouring countries.

Last year, Australia also announced the launch of the AU$20 million ($15 million) Clean Energy Seed Fund (CESF), which will provide seed and angel funding to ventures developing clean energy solutions.

In India, Asset management firm IDFC Alternatives Ltd announced in September last year to float a separate platform to hold its renewable energy assets.

“As we are looking small and medium scaled project which are not concentrated by large renewable players. The fund will have an attractive return and we feel this will de-risk the portfolio by diversification,” said Shankar.

March 2017

oody’s has assigned the stable Ba3 rating to the senior secured USD notes issued by Neerg Energy Ltd to the senior secured notes issued by Neerg Energy.

“We have assigned a first-time Ba3 rating to the senior secured USD notes issued by Neerg Energy Ltd (the Issuer). The rating outlook is stable,” the rating agency said in a statement.

According to the statement, the issuer’s credit quality is closely linked to that of the seven operating companies that together form the restricted group, which in turn is owned by Renew Power Ventures Pvt Ltd (RPVPL, unrated) – Such linkage is established because Neerg will be the holder of Masala bonds that will be issued by the companies within the restricted group and supported by cash flows from the restricted group. Holders of the USD notes that was issued by Neerg have a first ranking charge over the Masala bonds. On February 7 2017, Neerg has issued USD 475 million, which

includes a slight top-up on the amount previously estimated for the issuance, it said. While this decreases the amount of headroom, it is manageable within the Ba3 rating. The Ba3 rating is underpinned by a diverse set of long-term contracts that provide stable cash flows, have low operating risks and are comprised predominantly of wind and solar energy projects, it said. The restricted group’s cash flows draw from 12 different projects spread across five states in India. Neerg Energy Ltd, which is the issuer of the senior secured USD notes, is held by a trust and its ownership is not linked to RPVPL or its subsidiaries. Using the proceeds from the USD notes issuance, Neerg will subscribe to the Masala bonds issued by the specified seven operating entities of RPVPL and which together form the restricted group. The seven restricted subsidiaries have a capacity of 504 MW in wind and solar power plants Source:moneycontrol and are domiciled in India..

Northeast region adopts renewable energy to overcome power crisis

‘Delhi secretariat saves Rs 1 cr by using solar power’

A 40 kilowatt solar power plant was recently inaugurated in Assam’s Jorhat city with an aim to utilize the energy resources. In 2015, the then government of Assam sanctioned 50 lakh rupees to encourage solar power generation in the area.

The Delhi government has saved over Rs 1 crore in the last one year by running the Delhi secretariat on solar power, a senior official said.

T

he North-east region produces surplus power as compare to the demand. However, the surplus energy will be distributed to other parts of the country. Many solar power plant projects in the northeast are in pipeline, targeting to reach almost every household in the region. The Central government has been promoting clean energy under the Jawaharlal Nehru National Solar Mission. It targets deploying 20,000 MW of grid connected solar power by 2022 and is aimed at reducing the cost of solar power generation in the country. In 2015, Prime Minister Narendra Modi along with French President Francois Hollande launched an International Solar Alliance on the sidelines of the Climate Summit held in Paris.

In January 2016, PM Narendra Modi and French President Francois Hollande laid the foundation stone for the headquarters of the International Solar Alliance in Gwal Pahari in Haryana. As India is heading towards renewable based energy, more emphasis is now being given on solar, wind and other clear energy sources. The Northeastern states will play a major role in the production of clean energy in the country.

Sebi to finalise norms for Green Bonds post MNRE comments

Capital markets regulator Sebi will soon finalise its guidelines for listing of Green Bonds, which would facilitate raising of funds for investment in renewable energy space, after incorporating comments from the Ministry of New and Renewable Energy (MNRE).

O

ver a year ago, Sebi’s board had approved detailed draft norms for issuance and listing of Green Bonds in the stock market to help meet the huge financing requirements worth USD 2.5 trillion for climate change actions in India by 2030. However, the final guidelines are hanging in balance since then for want of certain inputs from the government side, a senior official said. Green bonds can be key to help meet an ambitious target India has of building 175 gigawatt of renewable energy capacity by 2022, which will require a massive estimated funding of USD 200 billion.

“Sebi had sent a draft of the proposed guidelines to Ministry of Finance for their comments. After discussion with concerned departments, the Finance Ministry had forwarded comments of the Ministry of Environment, Forest and Climate Change to the markets regulator. “However, Sebi was informed that the MNRE’s comments were still awaited and would be forwarded to the markets regulator immediately upon receipt of the same,” the official said.

Subsequently, Sebi also sent reminders to MNRE for their comments on the matter, he said, while adding that there now appears to be some progress on this front and the regulator would finalise the guidelines for green bonds soon. The new norms would also help the investors take informed investment

decisions and bring in uniformity in the disclosure requirements, Sebi had said in a statement in January last year after its board approved the proposal in this regard. Financing needs of renewable energy space in the country requires new channels to be explored, which can also help in reducing the cost of the capital.

Sebi had decided on the new norms after taking into account public comments to a draft paper issued by the regulator in this regard in December 2015. Issuance and listing of green bonds will be governed by the Sebi regulations for debt securities but the issuer of green bonds will have to make incremental disclosures. These norms would also provide for requirement of independent third party reviewer, certifier or validator for reviewing, certifying and validating the pre-issuance and post-issuance process, including project evaluation and selection criteria. However, this has been kept optional.

The issuer will have to provide the details of systems and procedures to be employed for tracking the proceeds, the investments made and earmarked for eligible projects. The same would need to be verified by external auditors. A green bond is like any other bond where a debt instrument is issued by an entity for raising funds from investors. However, what differentiates a green bond from other bonds is that the proceeds of a Green Bond offering are ‘ear-marked’ for use towards financing green projects. As of now, there are no standard norms for green bonds. According to Sebi, green bonds can help enhance an issuer’s reputation and attract a wider investor base, while benefiting the issuers in terms of better pricing of their bonds compared to a regular bond.

Cabinet approves enhancement of capacity from 20,000 MW to 40,000 MW of the Scheme for Development of Solar Parks and Ultra Mega Solar Power Projects

T

he enhanced capacity would ensure setting up of at least 50 solar parks each with a capacity of 500 MW and above in various parts of the country. Smaller parks in Himalayan and other hilly States where contiguous land may be difficult to acquire in view of the difficult terrain, will also be considered under the scheme.

The capacity of the solar park scheme has been enhanced after considering the demand for additional solar parks from the States.

The Cabinet Committee on Economic Affairs, chaired by the Prime Minister, Shri Narendra Modi, approved the enhancement of capacity from 20,000 MW to 40,000 MW of the Scheme for Development of Solar Parks and Ultra Mega Solar Power Projects.

The Solar Parks and Ultra Mega Solar Power Projects will be set up by 2019-20 with Central Government financial support of Rs.8100 crore.

The total capacity when operational will generate 64 billion units of electricity per year which will lead to abatement of around 55 Mn. tonnes of CO2 per year over its life cycle.

It would also contribute to long term energy security of the country and promote ecologically sustainable growth by reduction in carbon emissions and carbon footprint, as well as generate large direct & indirect employment opportunities in solar and allied indus-

tries like glass, metals, heavy industrial equipment etc. The solar parks will also provide productive use of abundant uncultivable lands which in turn facilitate development of the surrounding areas.

All the States and UTs are eligible for benefits under the scheme. The State Government will first nominate the Solar Power Park Developer (SPPD) and also identify the land for the proposed solar park. It will then send a proposal to MNRE for approval along with the name of the SPPD. The SPPD will then be sanctioned a grant of upto Rs.25 Lakh for preparing a Detailed Project Report (DPR) of the Solar Park. Thereafter, Central Financial Assistance (CFA) of up to Rs. 20 lakhs/MW or 30 percent of the project cost including Grid-connectivity cost, whichever is lower, will be released as per the milestones prescribed in the scheme. Solar Energy Corporation India (SECI) will administer the scheme under the direction of MNRE. The approved grant will be released by SECI. The solar parks will be developed in collaboration with State Governments/ UTs. The State Governments/UTs are required to select the SPPD for developing and maintaining the solar parks.

Ministry of New and Renewable Energy (MNRE) is already implementing a scheme for development of at least 25 solar parks with an aggregate capacity of 20,000 MW, which was launched in December 2014. As on date, 34 solar parks of aggregate capacity 20,000 MW have been approved which are at variSource:pib ous stages of development.

We congratulate the winners and are sure that comparatively they possess all right rationale and better knowhow / cost economics sense on desired returns to equity investors. While I believe every tariff is viable when you invest in a project. But the term ‘viability’ in renewables has assumed a new definition recently. It is time come to a consensus what should be the viable IRR for renewable projects in India?

What is baffling me today is how the nightlong action packed thriller resulting in tariffs as low as Rs 3.46 can be considered as ‘investor friendly’ or ‘discom friendly’ tariff?

Surprisingly, only a few months back majority of wind developers were fighting to improve the tariff of Rs 4.19 with regulators in Gujarat, which was ‘then’ considered quite

MP project shows cost competitiveness of solar energy: Icra With the solar tariffs falling to Rs 3.3 per unit for a 25-year PPA for the 750 MW Rewa Ultra Mega Solar project in Madhya Pradesh, rating agency ICRA said the cost competitiveness of solar against both alternate renewable as well as conventional energy sources has improved. The Rewa project is a 50:50 JV between Madhya Pradesh Urja Vikash Nigam and Solar Energy Corp of India (SECI).

“This is the lowest discovered tariff through a reverse auction based bidding route for grid connected utility scale solar PV project in India. This signifies a major improvement in the cost competitiveness of solar energy against both alternate renewable as well as conventional energy sources,” ICRA Ratings Senior Vice President and Group Head Sabyasachi Majumdar said.

“Viability of such tariff for project developer from its credit perspective will be critically dependent upon the availability of long tenure debt (of upto 18-20 year post project completion date) at cost competitive rate as well as more importantly, its ability to keep the cost of PV modules within the budgeted levels,” he said.

B

ased on an assumption of a capital cost of Rs 4.6 crore per MW and PLF of 21 per cent, ICRA estimates cumulative average debt service coverage ratio (DSCR) over debt tenure of 18 year at 1.25 times and project IRR at below 10 per cent, for a project with a levellised bid tariff of Rs 3.3 per unit.

low, not to mention that 50 paisa GBI was available over and above this tariff. At the above tariffs did the projects actually look unviable then, even when Gujarat discom is ‘A’ rated or will the recently bid wind projects be viable now? The power offtake is guaranteed in both cases.

But I am sure people who have won this bid have figured a smarter way out as developers will not put up projects to lose money.

Another interesting twist in this drama is that some turbine manufacturers themselves have also bid for quite low tariffs.

My immediate thoughts are: Has the turbine prices crashed by 15 – 20 per cent in those 24 hours? What is the logical justification of their past project costs based on IRRs viz a vis new pricing to clients based on tariffs. Have they embraced the changing realities?

However, ‘The End’ of this thriller is on a positive note where wind has competed with solar on ‘paisa’ to ‘paisa’ basis and is likely to give thermal a run for money. Let us wait for this blockbuster to perform at the box office.

In my opinion the winners areA Renewables B- Government C- Environment.

“Thus, any deviation in project parameters and cost assumptions may have an adverse impact on project returns and debt service ratios,” Majumdar said.

With competitive bidding route adopted for award of solar projects and fall in PV module price levels, cost competitiveness of bid tariff has thus significantly improved as evident in decline from Rs 6.5 per unit in 2014 to Rs 5 in 2016, and further to Rs 3.3. Against this, average feed-in tariff for wind energy and competitively bid thermal tariff (last 24 month period) remains at Rs 4.8 per unit and Rs 4?5 per cent, respectively.

“With policy focus on promotion of solar capacity and improved cost competitiveness, the Rewa project bidding will provide impetus on pace of awards by nodal agencies in solar park mode in other states, given the favorable tariff for the procurers who may be either distribution utilities or bulk/ open access consumers,” he said. Majumdar said while deemed generation clause for grid non-availability has been considered in the Rewa project bid for the first time, any similar measure at policy level if approved by the government so as to provide a compensation against loss of generation due to back-down/grid availability constraints, would remain a positive development for the wind and solar energy sector, given the incidences of back-down seen in a few states in the recent past.

rcelorMittal India has received possession certificates for 2,659 acres of private land following the acquisition of 1,827 acres and 832 acres in December 2011 and October 2012, respectively, it said.

A balance of 136.33 acres owned by the Karnataka government is being processed for allocation, it said.

Setting up of the solar park will contribute to the mitigation of Karnataka’s power crisis and participation in the National Solar Energy mission of the government of India.

“In this regard, the company has sought the state government’s permission to set up a solar farm of up to 600 MW. “The state government is considering ArcelorMittal’s proposal and the company is hopeful of receiving a favorable response to the proposal,” it said. orld’s largest steelmaker ArcelorMittal may set up a solar farm on land alloted to it for the proposed 6 MT Karnataka project in view of excess global steel capacity and delays in securing raw materials.

The company had entered into a pact with Karnataka government for setting up a 6 million tonnes (MT) steel plant with a captive 750 MW power plant at an estimated investment of $6.5 billion. “In view of excess capacity of steel world-wide and uncertainty in iron ore availability locally, the company is also exploring the possibility of utilizing the land in Karnataka for the establishment of a solar farm for generating solar energy,” the global steel giant has said in its latest report.

The NRI billionaire Lakshmi Mittal - led company in June 2010 had signed an MoU with the Karnataka government to set up a 6 MTPA greenfield project at Kuditini in Bellary, Karnataka. After failing for over a decade to set up plants at Odisha and Jharkhand, ArcelorMittal had signed the pact with Karnataka government for the plant but the same is yet to take off. While the company is facing raw material security issues in Karnataka, the projects in Jharkhand and Odisha were marred by delays.

Monocrystal introduces new PERC aluminum paste specially designated for a dot laser pattern

Soon, print solar cells at the cost of a newspaper Printing solar cells may soon be as easy and inexpensive as printing a newspaper, thanks to researchers who have cleared a critical manufacturing hurdle in the development of a new class of solar devices.

This alternative solar technology could lead to low-cost, printable solar panels capable of turning nearly any surface into a power generator, researchers said.

M

“Economies of scale have greatly reduced the cost of silicon manufacturing. Perovskite solar cells can enable us to use techniques already established in the printing industry to produce solar cells at very low cost.

Potentially, perovskites and silicon cells can be married to improve efficiency further, but only with advances in low-temperature processes,” said Ted Sargent from University of Toronto in Canada.

T

oday, virtually all commercial solar cells are made from thin slices of crystalline silicon which must be processed to a very high purity.

It is an energy-intensive process, requiring temperatures higher than 1,000 degrees Celsius and large amounts of hazardous solvents.

In contrast, perovskite solar cells depend on a layer of tiny crystals – each about 1,000 times smaller than the width of a human hair – made of low-cost, light-sensitive materials.

Since the perovskite raw materials can be mixed into a liquid to form a kind of solar ink, they could be printed onto glass, plastic or other materials using a simple inkjet printing process.

However, until now, there has been a catch – in order to generate electricity, electrons excited by solar energy must be extracted from the crystals so they can flow through a circuit. That extraction happens in a special layer called the electron selective layer (ESL).

The difficulty of manufacturing a good ESL has been one of the key challenges holding back the development of perovskite solar cell devices.

“The most effective materials for making ESLs start as a powder and have to be baked at high temperatures, above 500 degrees Celsius. You can not put that on top of a sheet of flexible plastic or on a fully fabricated silicon cell – it will just melt,” Tan said.

Tan and his colleagues developed a new chemical reaction than enables them to grow an ESL made of nanoparticles in solution, directly on top of the electrode. While heat is still required, the process always stays below 150 degrees Celsius, much lower than the melting point of many plastics.

The new nanoparticles are coated with a layer of chlorine atoms, which helps them bind to the perovskite layer on top – this strong binding allows for efficient extraction of electrons. Researchers reported the efficiency of solar cells made using the new method at 20.1 per cent.

onocrystal, a leading global supplier of PV metallization pastes and synthetic sapphire, recently announced the launch of its new EFX-9X series aluminum metallization paste for Passivated Emitter Rear Contact (PERC) solar cells, specially designed for a dot laser pattern.

New optimized paste content does not damage a passivation layer, and brings up to 17% higher local contact efficiency, compared to our previous EFX-series pastes. This results in overall cell efficiency gain up to 0.1%. Furthermore, the new product provides 30% lower consumption as compared to the market average, while maintaining high conductivity of an aluminum layer. EFX-9X series is an advanced solution for a dot laser pattern delivering our customers an excellent PERC solar cell performance.

“In the light of current market trends and the growing demand for high-efficiency solar products we are striving to provide our customers with high-end solutions, such as a dot laser pattern for PERC solar cells.

We are continuously upgrading our EFX-series metallization PERC-package in order to allow our customers maximize their product efficiency and production yields”, commented Vyacheslav Golovin, CTO of Monocrystal Pastes Division.

GOODS & SERVICES TAX

GST to increase solar tariffs, boost domestic manufacturing and jobs solar sector could see tariffs rise by nearly 10% if current tax exemptions were curtailed in the roll out of the Goods and Services Tax (GST), according to a study released by the Council on Energy, Environment and Water (CEEW).

M

ultiple GST rates and their uncertain applicability to different equipments and services for solar projects is a growing concern from solar project developers and investors. GST could also impact the pace of the second phase of solar park development for additional 20,000 MW capacity announced in the recent Budget.

The key contributors to the increase in solar tariffs, as a result of GST, would include increase in operations and maintenance cost, panel costs, and financing costs. The increase in solar tariffs would also vary across states; higher for states such as Rajasthan where VAT and Entry Tax exemptions are currently provided for solar equipment, as opposed to Andhra Pradesh and Gujarat where VAT and Entry Tax exemptions are not provided.

The CEEW study also finds that GST will give a boost to the government’s ‘Make in India’ initiative, improving competitiveness of Indian manufacturers of solar cells, panels and modules eliminate the cascading effect of the existing tax structure and introduce an input tax credit. Increased competitiveness of domestic solar manufacturers could create an additional 37000 new jobs in the solar manufacturing sector by 2022.

Even as India celebrates record low solar tariffs, the CEEW study finds that GST could possibly increase capital cost of a solar project by INR 4.5 million per megawatt if current tax exemptions were curtailed, setting back the sector in terms of cost competitiveness by about eighteen months.

Solar project developers have approached the government with requests to ensure that the current tax exemptions applicable to the sector continue so as to not negatively impact the efforts to achieve grid parity. The government currently collects less than 0.1% of its total indirect tax collection from the solar sector.

“With the annual solar power capacity addition expected to be more than 12 GW in 2017-18, it is vital that major hurdles for deployment, such as the potential impact of GST on the sector, be ironed out as early as possible. GST offers many long term benefits, but the Ministry of New and Renewable Energy (MNRE), Solar Energy Corporation of India Limited (SECI) and other related agencies must provide clear guidelines regarding the applicable GST slab for upcoming solar power projects and introduce government mechanisms to offset the short term negative impacts of GST. If current tax exemptions are curtailed, the impact of the increase in solar tariffs could be partially offset by policy instruments, such as Accelerated Depreciation benefits or Viability Gap Funding for projects incurring increased capital investments.”

- Dr. Arunabha Ghosh, CEO, CEEW

The recent Budget has already benefitted domestic solar manufacturers with the reduction of basic customs duty to nil for tempered glass used in the manufacture of solar cells, panels and modules and the reduction of countervailing duty from 12.5 percent to 6 percent for parts used in the manufacture of tempered glass which is used in solar PV cells, modules, etc.

Finance Minister Arun Jaitley announced last month that the GST may be implemented on 1 July 2017.

Multi-Si to Challenge Mono-Si’s Market Share as Black Silicon Technology Matures Ever since PERC technology is getting popular, mono-Si products continue to threaten the market share of multi-Si products. Therefore, multi-Si manufacturers start to pay close attention to black silicon technology, hoping to improve the lower cell conversion efficiency problem caused by diamond-wire cut wafers and find new market opportunities for large multi-Si capacities.

C

ompared with traditional slurry-wire cut, diamond-wire cut is faster and can come up with more-stable-quality wafers. Wafer cost can be reduced to US$ 6-10 cents/piece too using diamond-wire cut. However, since the surface of multi-Si wafer using diamond-wire cut is too smooth, sunlight can easily be reflected and cannot be absorbed by the cell, which leads to lower conversion efficiency. Because of this, surface etching must be performed. One of the technologies with high visibility is called black silicon.

Two types, three production processes Black silicon is an existing technology that comes back with the diamond-wire cut wafers. In 2016, quite a few manufacturers have begun to conduct research into black silicon, including Canadian Solar, JA Solar, Jinko Solar, BYD, Kyocera, and some Taiwanese makers.

Black silicon is mainly divided into two types – dry and wet etching, with a variety of classification. There are three major categories in the current market for black silicon technology – dry etching, wet etching, and additive. Additive is a type of wet etching but without the silver nitrate solvent used in standard wet etching process.

The three types of production processes are listed below:

Taking current technology development and equipment cost into account, Analyst of EnergyTrend believes that black silicon technology focuses more on additive production process in 2017, while dry etching is still developing. Yet, how wet etching uses the silver nitrate solvent has environmental concerns and is relatively unfavorable.

In addition, wet etching is less competitive than dry etching in terms of efficiency increase and less competitive than additive in terms of cost reduction. As a result, wet etching’s competitiveness remains to be seen.

Main competitor is conventional mono-Si If black silicon multi-Si cell works with PERC technology, the conversion efficiency can reach 19-20%, plus the cost reduced by using diamond-wire cut, its C/P ratio will directly challenge the position of conventional mono-Si cell. Meanwhile, mono-Si wafer capacity is not as sufficient as multi-Si wafer, which is difficult to win over the market share of multi-Si wafer and thus open a new market for black silicon multi-Si cell. Mono-Si PERC cell will enter the mainstream high-efficiency market in 2017 as the technology matures.

EQ

March 2017

We can see this from manufacturers’ expansion and high market demand of mono-Si PERC cells. Analyst of EnergyTrend forecasted that the black silicon technology will be clear in 1H17 and enter the mass production stage in 2H17.

The market response to the black silicon multi-Si cell will determine the future development of black silicon.

Heraeus Photovoltaics, the worldwide leading supplier of metallization solutions to the PV industry, introduces at the World Smart Energy Week in Tokyo a new generation of highly efficient metallization pastes. Whilst SOL9641B enables higher efficiencies gains, the other two metallizations pastes 9641Ax/ Bx and SOL570 pave the way for emerging solar screen technologies.

Substantial efficiency boost with SOL9641B On mono- and multi-crystalline ULDE and PERC cells Heraeus’brand new SOL9641B series with improved finger geometry helps boosting efficiencies significantly by up to 0.2%. Better contact formation and less shading enable this efficiency boost. The metallization paste demonstrates superior contact behavior on demanding emitters such as ultra-low doped emitters (ULDE). In addition, the organic vehicle system for ultra-fine line printing has been improved. A unique glass frit developed by Heraeus Photovoltaics enables a wider firing window toward lower temperature side. It is tailored to the low temperature processing needs of PERC solar cells and can be paired with the award winning SOL326 PERC backside paste to realize higher efficiencies and mass production yield.

SOL9641AX/BX – made for emerging printing technologies The new SOL9641AX/BX series is designed to realize the full advantages of zero degree mesh printing screens, also known as knotless screens. This emerging technology gives the paste more room to pass through. It features a unique paste rheology, enabling much better aspect ratio on ultra-fine-line fingers compared to conventional paste. An outstanding 0.1% efficiency gain can be achieved and the pastes are perfectly suited also for black silicon texturing. The aspect ratio achieved

by SOL9641Ax/Bx on knotless screen is 0.6-0.64, compared to the aspect ratio on conventional screen of 0.48.

Enhancing heterojunction and organic solar cells with SOL570 For emerging solar cell architectures such as heterojunction (HJT) or organic solar cells (OPV) Heraeus introduces the new SOL570 series as low temperature paste.

The improved paste chemistry combines the latest breakthrough silver powder development and organic design, allowing improved sintering of the silver at low curing temperatures.

Higher yield of solar wafers and enhanced solar cell efficiency with new HeraGlaze© coating by Heraeus Heraeus Photovoltaics, the worldwide leading supplier of metallization solutions to the PV industry, introduced HeraGlaze, a high-purity SiO2 diffusion barrier coating for enhanced crucible performance in wafer production.

I

t is the first product of Heraeus Photovoltaics beyond metallization pastes and a leap in quality and yield for integrated PV-manufacturers. With HeraGlaze the wafer yield is increased by up to

4% and cell efficiency is improved by 0.1%. Assumed an annual wafer production of 50GW today, HeraGlaze will be able to deliver close to additional 2GW per year without increasing wafer production capacity.

HeraGlaze is used in the very first step of the of the solar cell manufacturing process, when poly-crystalline silicon blocks are melted into a single silicon ingot. This early process is crucial for the quality of the ingots and thus for the quality of the final product – the solar wafers. The new product of Heraeus comes as a slurry, which is applied on the porous surface of the crucibles.

This can be done directly at the production site of the customer and allows to retrofit or upgrade existing crucibles.

As a result, the solution is very costefficientas no additional expenditures on new crucibles are required.

A NEW CHAPTER AS TECHNOLOGY LEADER HERAGLAZE acts as a barrier and prevents thctsthermally induced impurities such as iron are transferred from the crucible into the silicon ingot during the melting and crystallization of silicon.The higher wafer yield is achieved by increasing the usable section of a silicon ingot.

“HeraGlaze opens a new chapter in our roadmap as a technology leader and provides our customers with more added value. It’s our first product beyond solar cell metallization and another R&D landmark, which enables our customers to realize further efficiency gains,” says Andreas Liebheit, President of Heraeus Photovoltaics”.

TRADE WARS

“RelyOn Launches Single Axis Tracker”

Solar Energy has become the leading source of renewable energy in India in terms of new photovoltaic plant installations with government driving an ambitious 100GW target. Solar tariffs have been dropping over the last three years with each successive tender.

T

his dramatic fall in solar tariffs has come from economies of scale in procurement of solar modules, inverters and in manufacturing of mounting structures and reduction in cost of financing with global investors investing low cost funds into these projects. Companies are now beginning to look at innovative means to increase the energy yield of their solar installations to generate better returns from their projects and prepare themselves for further drop in prices in next round of bidding as the economies of scale taper off. The viability of solar PV sector is now going to be driven by innovation.

RelyOn Solar is a pioneer in the innovation race. It has continually strived to compete in the market by bringing new products like Solar DG grid controllers, off grid inverters and DC pumps. RelyOn Solar did a grand launch of their Single Axis Tracker at Leela Ambience Hotel is Gurgaon. It is a completely indigenous state of art single axis tracker solution developed specifically for Indian conditions. It is a robust, maintenance free system, which is easy to install in most geographical terrains across the country with minimal ground preparation.

It is targeted at major Independent Power Producers (IPPs Project developers and EPC installers for the large utility scale projects. So far most of the components of large PV plants are imported into India and this indigenous tracker by RelyOn Solar is a bold statement from a small company that-

The Product Launch event was chaired by Mr Deepak Amitabh CMD of PTC India. At the launch Dr Gundu Sabde – MD RelyOn Solar promised that this tracker will be a disruptive innovation for the solar utility market.

Success this year was driven largely by the utility-scale segment, which was bolstered by a pipeline of projects initially hedging against the extension of the federal Investment Tax Credit. Not only did it represent the most megawatts installed, but the utility-scale segment also featured the highest growth rate of any segment, growing 145 percent from 2015.

“In a banner year for U.S. solar, a record 22 states each added more than 100 megawatts,” said Cory Honeyman, GTM Research’s associate director of U.S. solar. “While U.S. solar grew across all segments, what stands out is the double-digit-gigawatt boom in utility-scale solar, primarily due to solar’s cost-competitiveness with natural-gas alternatives.”

T

he non-residential market also exceeded expectations, with two major growth drivers in the segment. The first is community solar, adding a record total of more than 200 megawatts, led by Minnesota and Massachusetts. Second, rate design and net energy metering fueled a rush in project development and installation growth across a number of major state markets, most notably in California. For the first time since 2011, nonresidential installation growth surpassed residential

www.EQMagPro.com

solar growth, which posted a still-impressive 2,583 megawatts. While growth in California’s residential market has begun to level out, strong growth in markets like Maryland, New Jersey and a handful of emerging states where solar has achieved grid parity, helped the residential segment to grow 19 percent year-over-year. As a result of a remarkable 2016, the U.S. is now home to more than 1.3 million solar PV installations, with a cumulative capacity of over 40 gigawatts.

Renewable Energy Mission Needs A Robust Grid Network

By Mr. Manoj Kohli, Executive Chairman, SoftBank Energy

A successful power transmission network for India will require a robust and flexible grid infrastructure within India and with neighbouring countries

Accelerating planning and completion of the power grid will enable the country to better manage power problems through efficient transmission system.

What is the Problem?

A

ir pollution in Delhi and metropolitan cities of India has dominated much of the recent conversation in the judiciary, government and media. Half of the world’s 20 most polluted cities, according to World Health Organization, are in India and these cities are immensely contributing to climate change. On 2 October 2016, India ratified the Paris climate agreement, officially emphasizing its commitment to reduce greenhouse gas emissions.

Nonetheless, just two years after embarking on the grand campaign to scale up country’s renewable energy capacity to 175 gigawatt (GW) by 2022, India is facing a serious problem. While wind power has faced curtailment in the past

www.EQMagPro.com

in Tamil Nadu, solar energy is being curtailed for the first time, sometimes over 50% during peak generation periods.

Utilities have the discretion to decline buying power in the name of stabilizing the grid or preserving the grid balance.

Grid curtailment is one of the biggest operating risks for the future of the solar sector given India’s transmission capacity is already overburdened. The curtailment threat is highest in Jharkhand, where the average daytime power demand is less than 1 GW but the state has already tendered 1.2 GW of solar projects. As India aspires to lead the world in renewables, will the grid be an obstruction or a catalyst for renewable energy development?

EQ

RENEWABLE ENERGY

Causes of the problem

T

he problem is largely a technical one.

Solar and wind power are not as easy to control as traditional fossil fuel plants, so power grids need to become flexible enough to handle frequent changes in power generation.

Additionally, distance is an issue. In India, six states in the western and southern regions account for 80% of all of the country’s currently installed solar capacity, but only 38% of power demand. For grid operators used to being able to turn fossil fuel plants on and off at will, these changes are easier. If new measures are not urgently put into place to accommodate variable renewable energy sources, a situation can arise where the grid operator will be unable to use solar and wind power when it becomes available.

RECOMMENDATIONS TO GOVERNMENT How can India learn from the experience of other countries and rapidly scale up renewables without any wastage or curtailment?

1

Experience of other countries

O

ther countries have already dealt with this problem with varying degrees of success.

Germany and the US have relatively high levels of solar and wind penetration and low curtailment rates, while China has major curtailment as the share of wind and solar in the energy mix increases. Germany achieved low curtailment rates with high renewable energy penetrations through improved grid planning and changes to the power market structure. In another case, the state of Texas implemented smaller changes to how the grid is operated and it made all the difference. For example, the Texas grid operator ERCOT shifted from 15-minute dispatch intervals on the intra-day market to 5-minute intervals, allowing for superior planning around variable wind and solar power plants. (India currently uses 15-minute dispatch intervals.).

Although China has been able to build out renewable energy capacity swiftly over the past decade, it has taken much longer to develop the transmission infrastructure and make the institutional changes required to utilize all of this new power. Grid curtailment issues continue to impact the export of power from solar projects and some provinces such as Gansu and Xinjiang (31% and 26% of curtailment respectively) have been hit severely.

EQ

March 2017

Execution of green corridor

T

he variability of solar and wind energy can be mitigated to a large extent through transmission interconnections, thus, the first priority for India is to complete the transmission infrastructure through its $3.5 billion green energy corridor program so that renewable power can be transmitted where it is needed. Further transmission systems need to be built ahead of renewable energy generation as transmission projects typically take up to five years to become operational whereas solar projects become operational within 12-18 months. There are significant power surpluses in some states and power deficits in others. New investment in interstate and intra-state transmission systems will help balance out such disparities.

2

Strengthening the national grid

3

Emerging role of electricity storage

A

ccelerating planning and completion of the power grid will enable the country to better manage power problems through efficient transmission system.

The objective of “One Nation-One Grid-One Frequency” is necessary to get full utilization of the nearly 175 GW of solar and wind capacity that will be installed by 2022.

Besides the National Power Grid, transmission lines within states need to be completed and modernized. This will also enable India to take advantage of the vast amounts of solar energy available from Ladakh, a cold desert and Jaisalmer, part of the Great Indian Thar desert, to power future energy needs of heavy consumption areas.

E

lectricity storage will play an important role in reducing curtailment. Electricity storage is unique in the Indian context where more than 300 million people still have no access to power. The cost of storage is still a major barrier to mass adoption, but prices are dropping rapidly. As the price of energy storage drops, it will become an increasingly compelling complement to variable renewable energy. India stands a unique chance of leading the world in electricity storage.

To facilitate this, the government should encourage battery manufacturing under the “Make in India” programme, as import of grid-scale batteries due to their extreme weight not only leads to high transportation costs but also creates other logistical challenges. In this regard, the government can colocate battery manufacturing with top solar regions in India, which are attractive to storage companies.

Creation of South Asian grid

lexible generating resources (quick start, swift ramp-up or ramp-down) such as hydro and gas plants along with active distribution management system would go a long way to improve the stability & reliability of the grid. It may be added here that India’s neighbouring countries— Bangladesh, Myanmar, Sri Lanka, Thailand, Bhutan and Nepal have large hydro, gas & renewable resources and transmission interconnection with these countries would further deliver diversity to mitigate variability of the grid. India is already interconnected with Bhutan and Nepal, and has plans to interconnect with other countries.

In this regard, India should envisage creation of a South Asian Grid connecting Malaysia and Singapore via Thailand similar to the synchronous grid of Continental Europe. Though, the Asian super grid project linking the enhanced electric power systems of China, Japan, Korea, Mongolia and perhaps Russia has been proposed by SoftBank, this new South Asian Grid will add efforts to cultivate extensive economic and strategic relations with the nations of South Asia. India’s NITI Aayog has created a framework for public-private partnerships for transmission investment, but land acquisition and permitting are still major roadblocks for private developers hoping to complete a project on schedule. Reducing the time and cost of land acquisition will be essential to making infrastructure projects attractive to developers and unlocking the private capital needed to finance transmission lines.

www.EQMagPro.com

High renewables and robust grid

T

hree events are set to transform the electricity sector in India in the next decade: 300 million people who have no access to electricity today will have sufficient power; an unprecedented GDP growth of ~8% per annum will drive the electricity consumption further; and the share of wind and solar will rise to levels of ~20% in the India’s energy mix.

A successful energy transition for India will require a robust and flexible grid infrastructure within India and with neighbouring countries.

INTERViEW INTERVIEW

Exclusive Interview with

Ivan Saha EQ: How much modules have you supplied to India till now, what is the target/ expectation in 2016-17 IS: Till 2015-16 we had shipped 500 MW in India. We will touch ~ 900 MW this year.

EQ: The recent aggressive bidding by various developers keeping Solar Tariffs in the price range of Rs.3.32 – Rs.4.34 per kWh in various Solar Tenders…Whats your view on the viability, Costs & timeline pressures, Resource Challenges (Materials, ManPower, Execution, Grid Connection, Land Possession) etc...

IS: 2017 witnessed a record decline in Indian solar energy tariff, standing at INR 2.97 per unit per unit (in a bid for three 250 MW units of Madhya Pradesh’s Rewa Solar Power Plant). Falling tariff indicates Government’s effort to make the power sector value chain more efficient to deliver uninterrupted energy support (electricity). However, the mismatch between project cost and ROI with low tariffs is clearly visible. There have been consistent drop in solar module and other component prices, yet that alone does not substantiate 20-30% (and more) drop in bids. Low tariff bids also bring for the issue of project sustainability.

Additionally, there is another issue of influx of low quality modules in the Indian solar industry. India needs to put more focus on developing and better asset quality control in solar development, to avoid putting lifespan of solar plants in question.

There are many challenges for domestic manufacturers as we have to compete with 10 per cent cheaper foreign

imports. However, we acknowledge and appreciate Government’s efforts of helping domestic manufacturers by bringing NTPC, Railway and other Government units as the power purchaser to provide security for the project bidders. However, Indian Government still needs to focus on skill development, investment in R&D, unregulated module imports, and easy land procurement for domestic solar companies to make a brighter future.

EQ: Kindly enlighten our readers on the performance of your modules in India in various geographic locations, customer feedback.

IS: Our module range starts from 10 Wp and stretches to 345 Wp. This huge range of offering has enabled us to serve industrial, commercial, residential and utility scale development projects.

dia and an exponentially increasing global footprint.

With the rapid decrease in modules prices in the last year from $0.45 per Watt peak to around $0.33 per Watt peak today and with a forecast of a price below $0.29 in the coming year, the thought which crosses the mind of a IPP/EPC is “With falling module prices, will Tracker economics work out?”

To answer the above question, we reviewed the two most recent solar tenders concluded in India in light of whether tracking solution will improve the economic returns. One tender was for an EPC and the other one for a DEVELOPER. Both saw very aggressive bidding.

Both case studies take into account the below listed assumptions and both PROVE A CLEAR CASE FOR TRACKERS, even in a scenario of very low module prices (decreasing from $0.33/ Wp to $0.25/Wp)

INTERViEW INTERVIEW

Exclusive Interview with

Sven Kramer EQ: Please describe in brief about your company, directors, promoters, investors, its vision & mission Kramer: A spirit of innovation and a clever mix of industries have taken the German-based family business to become a global leader in system production. Today, teamtechnik is Germany’s largest owner-managed company in the field of assembly and test equipment.

We are independent and therefore highly flexible. The companyhas been developing and building innovative automation solutions for 40 years.We concentrate our efforts on three sectors: Solar, Automotive and Medtech.

A key new business area is also assembly and test lines for e-mobility solutions and batteries. Today the company employs 900 people around the world. teamtechnik Group has 5 production sites in Germany, Poland, China and the USA. In 2004 the Group entered into the solar technology segment with the development of the stringer systems for the interconnection of solar cells. teamtechnik gained quickly a clear competitive advantage with its fast-cycling production systems as well as its outstanding product quality and became the uncontested technology leader.

EQ: Solar Trade Wars : What are the benefits to Indian manufacturers Kramer: Nobody will win with a trade war. Protection is required if unfair competition is in the market. Unfair is for example if the selling price of solar modules are below the costs of materials. But there is an economy of scale. It will be difficult for a small manufacturer to compete with a big GW manufacturer which might be even vertically integrated. So certain protection and support is required to establish a solar manufacturing

base in India.

EQ: What are the trends in new manufacturing technology equipment, materials, processes, innovations etc…

Kramer: High speed, perfect string quality together with high production reliability 24 hours a day are the key factors in the market to be competitive. This is the trend.

The industry has shifted from 3 busbars to 4 busbars.

Now we see at our customers the interest in processing 5 busbar cells. Further more we see cells with a higher efficiency such as mono PERC cells or even bi-facial cells. Also half cut cells are becoming more widespread since the power output of a module with half cells can be increased by up to 15 Watts compared to a full cell module. In addition we see new materials to increase the power output like light trapping ribbons (e.g. LHS ribbons) which can increase the power output of a module by 2.5 to 2.8%.

Overall there are many ways to increase the power output of a solar module. The good thing is that teamtechnik stringers are prepared and can be upgraded for these new materials. We support our customers on an individual basis by developing new soldering recipes and the soldering parameters required for their specific materials.

EQ: What is your market share in the solar pv manufacturing market Kramer: teamtechnik has more than 700 stringer systems in the market and more than 22 GWp of solar modules are produced every year on teamtechnik stringer systems.So far we have supplied more than 2 GW of stringer production capacity to India in the last 15 months.

INTERVIEW INTERViEW

Vice President Sales Solar Technology, teamtechnik Group

EQ: teamtechnik is well known for delivering high-end stringer systems and we would like to know all about the newest Stringer TT4200 GIGA. Kramer: The Stringer TT4200 GIGA is our latest and most powerful system. It requires only 15 m² of floor space and produces up to 130 MWp per year ¬– a world record. With the TT4200 GIGA we have two soldering tracks combined in one machine. The system has one centralized cell feeding with a cycle time of 0.85 seconds or 4200 cycles per hour. After the cell feeding, fluxing and cell inspection, the cells are placed alternately on the left or the right soldering track. The soldering track is identical to the stringer system TT2100. For the soldering, the cycle time is 1.7 seconds. The proven system produces solar cell strings with a constantly high string geometry quality and a very impressive and precise ribbon positioning accuracy.

Contactless IR light soldering guarantees breakage rates of less than 0.2 percent. Our stringers preheat the solar cells uniformly, solder them, and then the cells are gradually cooled in a post-heating section. These processes are very gentle. The cells do not undergo any abrupt temperature shock so we can also avoid micro cracks.

EQ: Layup systems to match the teamtechnik stringers. What are the advantages to module manufacturers of this total solution?

Kramer: We can supply our stringer system with or without our layup system. Depending on the module line integrator, we can either ensure that the stringer will work with the integrator layup system or we can supply our stringer plus

www.EQMagPro.com

our layup system. For customers who decide to order our layup system, this means total connectivity for an output of 130 MWp. The complete system consists of proven and tested modules, stringer, robot and positioning station.

Everything perfectly matched. Rapid installation times and a perfect production launch are further benefits for our customers. The integrated 6-axis robot allows the system to be adapted quickly to different applications or cell and glass sizes.

EQ: Technology Obsolesence : What solution do you offer to your customers against possible future technology obsolescence when they buy your equipment.

Kramer: Our current systems are highly flexible and can easily be upgraded to 6 busbars and a wide range of new cell and ribbon types. Also stringer systems which have been supplied several years ago, such as the TT1200HS, TT1600 or TT1800 can be upgraded to 5 busbars. The stringer system was designed for the processing of 2, 3 or 4 busbar cells. Our engineers found a way to upgrade them to 5 busbars so that our customers can process these cells as well on our stringer systems. With the higher number of busbars the ribbons are getting narrower. Our latest stringer generations TT4200GIGA and TT2100 can handle ribbons with a width of only 0.6 mm.

As another item I would like to add that our stringer systems can be upgraded to process light trapping ribbons (LTR). These ribbons have a special structure embossed to increase the reflection of the sunlight hitting the ribbons in order to increase the power output of the solar module.

This also enables our customers to increase the power output by 2.5 to 2.8%. Overall I have to say that customers using teamtechnik stringers are ready for the future and can rely on our technology.

New STRINGER TT4200 GIGA with high production capacity of 130 MWp and a footprint of only 15 m²

EQ: What are the various technologies available for manufacturing and what’s the advantage & disadvantage in the tech or equipment you offer?

Kramer: We offer our Stringer System TT4200 GIGA and TT2100. In addition we can provide our Layup System matching the capacity of the Stringer Systems. The TT4200 GIGA is designed for customers with a production capacity with more than 500 MW. It is a compact system with a high production capacity. The soldering process itself is the same with the TT4200 GIGA and the TT2100. At the end of the day our customers have to decide which solution they prefer, depending on available space, production capacity and required redundancy.

For high efficient Hetero-Junction Solar Cells (HJT) we also have our TT1400ECA in our product portfolio. With this technology we connect the solar cells with a light trapping ribbon (LCR) and an Electrical Conductive Adhesive (ECA).

This allows us to process cells at a lower temperature of approx. 150 ºC or 160 ºC. With the soldering process a temperature around 190 ºC to 210 ºC is required. Since HJT cells are more sensitive for the temperature and some cells will reduce their power output at higher soldering temperatures we can provide a solution to customers who are interested in producing the next generation of solar modules.

EQ: Technology road map in terms of 1500V , Double Glass, BiFacial Cells, PERC/PERT Technologies, Hetero Junction, 5-6 Busbars upcoming game changes technologies etc…

Kramer: All of the above can be processed with teamtechnik equipment. All of our Stringers can process bi-facial cells (if they can be soldered which depends on the paste used 70

EQ

March 2017

during the solar cell manufacturing process). If you use a bi-facial cell, then of course you have a double-glass design.

One important item so far not many people paid attention to is the ribbon position on the back side of the cell. Since we use our patented hold-down devices in combination with our vacuum transport system on our stringers we can achieve a very precise ribbon positioning, not only on the front side but also on the back side of the cell. With a double-glass module you will see of course also the ribbon on the back side which is, with a conventional glassbacksheet module, normally covered up by the backsheet.

The interesting question will be, how will solar module manufacturer measure the efficiency of the backside of the module with a bi-facial module. You can achieve approx. 10 % higher power output. But of course it depends on where the module will be installed and how much sun light will be reflected onto the backside.

Our customers are using more and more PERC and PERT cells. Our Stringers are design to process them without any issues. Also 5 and 6 busbars can be processed.

We do not think that the number of busbars will increase above 6. We have performed a research study together with the SERIS institute of the University in Singapore.

Simulations showed that the power increase from 6 to 7 busbars is minimal and it does not account for the higher cost of the materials and for having one additional ribbon within the module.

In regards to the HJT technology we have to see if and when more manufacture will invest in the technology. We have developed a tool which can interconnect the cells, our TT1400ECA, but so far there are not a high number of available HJT cells in the market. In my opinion this is due to the higher efficiency of the PERC and PERT cells and that existing lines can be retrofitted for the PERC technology.

www.EQMagPro.com

INTERVIEW INTERViEW EQ: What is the efficiency, costs, roadmap of solar pv modules/cells Kramer: This a question for the solar cell and solar module manufacturer.

EQ: Please present some examples of your equipment & technologies in India and worldwide and their performance.

Kramer: One example, Vikram Solar, Indian manufacturer of photovoltaic systems, has decided to work with teamtechnik to expand its production to manufacture enough solar modules to generate 2 GW, up from 500 MW. teamtechnik has been given the job of developing and constructing production lines for producing these solar modules.For Vikram Solar, teamtechnik’s worldwide service network was a decisive factor in choosing the company, alongside the technical benefits of teamtechnik’s stringer and layup solutions.

At Vikram, for example, it was important to integrate the relatively novel, but highly effective PERC cells and bifacial cells in the production process. It was no problem for us.

EQ: What is the future of solar manufacturing technologies Kramer: We are currently seeing a trend towards 5 busbars.

By increasing the number of busbars the resistance losses can be reduced. Based on our research and development work with the SERIS Institute at the University in Singapore we know that the maximum number of busbars will be 6. You can of course increase the number of busbars further, but based on the simulation performed by the SERIS Institute the power gain achieved after 6 busbars is only minimal.

STRINGER TT4200 GIGA: Smooth and gentle soldering with IR light and closed loop control.

EQ: India currently has around 1.2 GW Cell Manufacturing and 5GW of Module Manufacturing…..what are the opportunities, challenges in manufacturing in India Kramer: India is expanding their manufacturing base. It is the correct decision of the government in India to support local manufacturing. Only with a local manufacturing base the solar energy can be more widespread in India because more and more people are supporting it. Our customers are facing several challenges. One is the availability of raw materials and local manufactured solar cells. In addition financing the equipment is a challenge.

EQ: India is currently ramping up manufacturing capacities…how much capacity addition do you forecast ?

Kramer: Forecasting is always difficult. But personally I see a big potential in India. Solar Energy can be installed within a short period of time. The costs for solar modules have been reduced over the last few years a lot and therefore solar energy is competitive with fossil fuels. India is one of the fastest growing economies and a lot of additional energy will be required in the next few years. Solar will be able to provide clean energy to the big cities in India as well as to rural areas. So I personally hope that more solar energy will be added in order to keep the air clean or cleaner in India. The existing companies in India will expand their manufacturing capacities and new players will enter the market. On the solar module manufacturing side I see a potential of 10 GW to 15 GW of production capacity within the next few years in India.

N-Type Bifacial Cell Technology, A Most Efficient Electricity Cost-Effective Solution

Introduction

W

ith the increase in the proportion of distributed PV system in the PV market and the promotion of high efficiency single crystalline solar cell technology, more and more institution and enterprises focus on the bifacial structure based on N-type silicon substrate. N-type bifacial cell and module show excellent performance in the regions of highly reflective ground, vertical installation, space station, photovoltaic building integration, parking shed, noise walls, snow, desert and other regions because it’s both side power generation characteristics. Therefore N-type bifacial cell has gradually sought after by the market. According to SEMI international photovoltaic technology roadmap forecast [1], N-type cell market share will be more than 20% to 2019, while it is more than 30% to 2025.

igure 1a shows the architecture of typical n-type bifacial solar cell in the market. The P+ emitter layer and N+ back surface filed (BSF) layer were form on the front side and rear side of textured n-type substrate, respectively. Passivation layer and anti-reflection layer were form outside both emitter and BSF layer. Silver paste was print on both side and co-firing to form metal electrodes to collect current. Typically, the wafer thickness is around 170-200μm and a wafer resistivity of 1-7Ω•cm is preferred[2,3]. This structure can reach an efficiency of 24.5%[4, 5] in laboratory. Infurther development, the efficiency can reach up to 24.7%

here are several different processes to manufacture such an n-type bifacial cell, such as panda technology from Yingli solar, spin coating based technology from PVGS and so on. Jolywood developed a bifacial cell technology based on ion implantation with the efficiency up to 21.5% at front side

(STC) in average and 19% at rear side (STC). As shown in Fig. 1b, the N-type bifacial cell can be implemented by the shown process sequence using an ion implantation technique. This process flow has the advantages of simple process, high yield and high conversion efficiency.

and high yield. Because of the advantages of simple process, high yield, high conversion efficiency, good reliability, easy to upgrade technology, etc., itâ&#x20AC;&#x2122;s believed in the future N-type market this bifacial technology will be much favored by the market.

Analysis of levelized cost of electricity

D

ue to the price decrease of the module and material, the module price plays a much smaller role in the PV system cost than several years ago. Thus, levelized cost of electricity (LCOE) analysis is important for end users.

N-type bifacial cells can be assembled in a double glass module or glass-transparent backsheet module according to glass/encapsulate/bifacial cell/ encapsulate/glass structure and glass/encapsulate/ bifacial cell/encapsulate/transparent backsheet

structure, respectively; The transmittance of transparent backsheet is close to 90%, slightly lower than glass.

But it has a very light weight Vs. glass. The two kinds of modules can absorb irradiation from both side to generate electrical power, shown in figure 3. Here a PR (performance ratio) factor was used to evaluate the power generation from the backside, which was defined in the following equal (equation 1). This PR factor indicates the ratio of the actual power generation to the theoretical power generation of the nominal power.

PVGS Japan have test power generation performance with different double glass module on different reflection ground [8]. In the test, two small systems with same watt-peak were installed on ground with white shell (system A, high reflection ground) and

grass(system B, low reflectivity ground) as shown in figure3a and 3b. The measured PR data was shown in table 1. It can be seen that bifacial system has better power generation ration, which is up to 18.7% higher than conventional mono facial system.

For the typical south faced PV system with 30° tilt, the electricity generation increase rate can reach up to 26% in sunny days. It can be even high in cloudy days, which can reach up to 38.6%. Detail data was shown in Figure4.

Figure 4,electricity generation increase rate compare with multi system on cement floor (all system is south faced, 30degree tilt)

Here a rear benefit of 20% was used for calculation. Table 2 shows the different cost per watt by different module based on 100MW PV plant exclude module cost. This indicates that n-type bifacial plant cost exclude module is 25% cheaper than p-type multi plant and 20% lower than p-type mono plant if rear benefit was 20%. www.EQMagPro.com

For different installation, different benefit from rear side also been calculated, list in table 3. This indicates that the n-type system with high power is one of the most cost-effective solution. The system cost will significantly decrease when the system get more benefit from rear side of bifacial modules.

Application of N-type bifacial cell and module

N

-type bifacial cell and module show excellent performance in the regions of highly reflective ground, vertical installation, space station, photovoltaic building integration, parking shed, noise walls, snow, desert and other regions because it’s both side power generation characteristics. This characteristics greatly expanded the application of N-type bifacial cells and modules[8,9,10].

One of the most important application is vertical installation system. The amount of electricity generated has no correlation with the orientation of the vertical installation.

The north-south bifacial vertical installation system shows a

parabolic electricity generation during the day, with the peak generation at 12 o’clock, east-west bifacial vertical installation system has two peaks at 9:00 am and 15:00 pm, respectively.

The power generation equals 90% of the optimal installation and 130% of the south face vertical installation of monofacial modules with same watt-peak, shown in figure 5a.

Because of the unique advantages of the vertically installed bifacial system, it is ideal for used in soundproof walls on both sides of highways and train stations. Fig 5b shows the first PV soundproof walls installed on the edge of the freeway overpass at Zurich, Switzerland [10].

PV MANUFACTURING The integration of photovoltaic buildings is an important trend in the future development [9,10].In Japan, an architect must take into account the photovoltaic power generation system in the housing design. Double glass modules are undoubtedly the most powerful competitors in this trend. Its characteristics such as double-sided power generation, vertical installation, adjustable light transmittance, good heat dissipation and so on, can been fully exerted in BIPV system. Figure 6 show some examples of photovoltaic building integration system.

s infrared light cannot be absorbed by silicon, based on bifacial cell structure, most of the infrared light can go through the cell. Furthermore, materials used in bifacial module such as glass, encapsulate and so on do not absorb the infrared light neither. Thus, the heat of the bifacial module is relatively small. The data shows that the glassglass PV modules have a 5 to 9 lower working temperature under normal working condition than conventional single-

glass modules [10]. For the crystalline silicon cell system, the power coefficient is about -0.42% per degree, therefore, in the desert and other high temperature areas, using bifacial system has an obvious advantage. Similarly, in the International Space Station, due to the absence of the atmosphere, the heat generated cannot be effectively distributed, resulting in high module operating temperature.

Bifacial modules can effectively alleviate this problem.

With the popularity of N-type solar cell and large-scale applications, there will be more and more researchers and enterprises continue to expand its application areas according to N-type bifacial solar cellâ&#x20AC;&#x2122;s characteristics.

Material Innovation Reduces LCOE

I

n current PV industry, crystalline silicon is the main product since its high transform light to electricity rate, matured producing process, and rich sources of raw materials and so on. Crystalline silicon is applicable through crystalline silicon cells and encapsulates combined PV module, which in the end will be able to generate electricity. Current PV module encapsulates structure is fallen into pattern in eighties, 20thcentury, shown as Pic.1 below, the module is consisted by glass, EVA, cells, backsheet, etc. Among these materials, backsheet is the outer layer of modules on the backside of module which directly facing the outer environment, protecting the inner materials of module and sustain them. The backsheet should perform the function of insulation, weather resistance and water vapor barrier. So the performance of backsheet will determine the life time and efficiency of PV modules, thus lead to the difference of PV generation cost. At the same time, backsheet can increase the reflection via the interval space between the cells, thus help increase the power of module and decrease the PV generation cost.

The higher reflection rate of backsheet inter layer, the higher power the module would obtain, and so more contribution to lower the generation cost. It’s the reason that reflection rate of backsheet inter layer is also important factor for PV generating cost down. The backhseet is a multi-lay structure with the PET is middle layer, which is the main composite of backsheet, also called base material. The PET film has good performance of insulation, mechanism and Water vapor barrier. But PET’s weather resistance is not very good, which needs to be protected for fulfill the lifetime stan-

dard of 25 years of the PV modules in outer field.

On the early stage of PV industry’s development, backsheet PET is mainly protected (Both side) by Tedlar film, which is produced by Dopont, it is also an exclusive PR product , the structure of this kind of backsheet is Tedlar//PET//Tedlar, also known as TPT backsheet. Tedlar film is PVF film, enjoys great performance of anti-UV, anti-high Temperature, anti-corrosion. PVF film is also a material in market till today that has a 30 year field application material PVF Film is by Biaxial stretching process, strengthened on both TD and MD, mechanism is balanced, and with good anti-aging performance it can endure humid heat, UV, TC and other harsh conditions. Though Tedlar film has above excellent functions and on site proof, due to this unique in manufacturing process, the surface of PVF film is easy for appearance of pinhole, in actual extreme climatic conditions, vacuum zone cannot protect PET ina proper way, thus lead to regional performance degradation in backsheet area, backsheet is easy to get destroyed, then influence the protection of cells by backsheet, shorten the lifetime of PV modules. On the other hand, the reflection rate of Tedalar film is quite low, it can’t help increase the power gain in PV modules, this makes Tedlar film at a disadvantage in generation cost down process. Also due to its unique manufacturing process, the cost of it is too high, cannot fulfill the development demand of PV industry. Under the above factors, another protection film called Kynar was developed in market, this film is produced with PVDF film by France’s Arkema. This Kynar film is also approved on site by Arkema more than 20 years, highly recognized by end users.

But PVDF film is week in MD and TD’s stretching or even with no stretching, easy to lead imbalance of mechanism, a big amount of acrylic when making film leads to inherent brittleness. All these factors lead to break or crack of PVDF film in outer site field under combined stress in different conditions. Besides, Technical threshold of PVDF is low, currently there are too many manufacturer with different standard of quality and performance. Anti-aging function of PVDF film varies from one another.

Some of the low quality PVDF film is easy to break under accelerated aging test in laboratory, shown as Pic.2, this also indicates the risk of this model on site.

o matter T or K film, all are laminated on PET surface by adhesive, this model is called laminating backsheet.

There is a film making process and PET lamination process by both T and K film, this material lead to poor weather resistance, under light damp heat condition, it is easy to get hydrolyzed, degradation aging, this leads attenuation of adhesive property, PVF/ PVDF film will be delaminating with PET layer, this is an unavoidable weakness of laminating backsheet.

To lower the cost of backsheet and solve the above problems, some of the backsheet manufacture developed the extrusion nonefluorine backsheet like PA, PET based backsheet. But coextrusion structure PA or PET backsheet though inner layers are enhancement property based PA or PET material, due to its own performance deficiency of raw material, the weather resistance is very poor, especially in harsh condition area.

Within 3 years, the backsheet even appear cracks by PA backsheet, thus lead to degradation and power decrease of modules.

Show is Pic.3, coextrusion based PET backsheet is also easy to get yellowing or cracked. Thus, this coextrusion based none fluorine backsheet will sooner be knocked out in the market. To sum up, TPT/KPK laminating backsheet’s cost is high, also weak performance in some function; PET and PA backsheet’s cost is low, but very poor performance, these models cannot guarantee 25 years lifetime of PV modules in outer field, on the contrary lead to generation cost higher. Co-developed with Key Lab of Organsilicon Chemistry and Materials for years, Jolywood successfully developed a subversive

FFC backsheet is an integrated film backsheet based on casting tangent roll coating technology and plasma technology. The backsheet structure is shown as Pic.5, still based on PET as base material, but PET by FFC is protected effectively by tetra fluorine coated layer. This on line film-membrane Integration technology highly reduced the manufacturing cost, also since no usage of poor performance of anti-aging Polyurethane adhesive, the risk of peeling off between base material and protection film has been avoided. On line film making’s main material, FFC coating layers from Daikin Japan’s FEVE. Daikin is world’s famous FEVE resin manufacturer, the fluorine-carbon coating material has been widely used in bridges, constructions, and port machineries’ out layer protection part, this material has 25 years plus outdoor application history.

Compared with traditional TPT and KPK backhsheet, FFC has the same excellent performance norm.

1. Weather resistance: Via high-low temperature 600 circulate, DH accelerated ageing 3000H, HF 30 circulate test (3 times of IEC standard); UV+ Aging (UV+DH) 130kw/m2\ QUVB aging test 4000H , Yellowing index Δ<5, this can make sure modules will meet 25 year lifetime.

2. Strong bonding strength: bonding strength with

EVA>80N/cm, strong > 80N/cm reduce the risk of backsheet bubble, peeling off , etc.

3. Water vapor barrier: Water vapor barrier rate <2.0g/m2.d, high water vapor barrier guarantee the adhesion with EVA, reduce the speed of cell’s corrosion by water vapor, increase the lifetime of modules at same time reduce the generating cost.

Compared With Tpt, Ffc Enjoys Higher Reflection Rate. Show As Pic. 6, By Same Power Range Of Solar Cells, The Modules With Ffc Backsheet Got 2 Watt More Power Than Tpt. This Also Help Reduce The Generating Cost.

SOLAR ROOFTOP

By Nimish Prabhukhanolkar, Partner/founder, AGAMI ENGINEERING

Do Solar IPPs in India have sufficient information when selecting a vendor for either a Fixed Tilt or a Tracker MMS? THE ANSWER IS SURPRISINGLY - MORE OFTEN THAN NOT , THEY DO NOT!

t is the modern day Gold Rush. Everyone wants to win a solar project. They bid aggressively. The only way to win this bidding war is with low costs. “Cost is king and everything else be dammed!” Once the bid has been won, almost always at very low bids, the pressure is on everyone to deliver. Aggressive bidding by developers to win projects has meant that very low project costs are inevitable and they are then thrust on to the suppliers. Technology selection of Modules and Inverters is much easier to do as compared to BOS, specially Structures.

Currently MMS designs are done using wind loads derived using IS 875III:1987/2015/ ASCE7-05/10 / EURO wind codesand structures are designed as per IS 800:1984/2007 / IS 801:1975.

Very often, MMS vendors DO NOT take into account the “eccentric” moment induced in the structure due to flow of wind. This is because this particular clause appears as a footnote and is often missed. Very thin, cold formed members are designed using IS 800 and IS 801 only. It is well-known a lot of members design in tracker MMS is governed by torsion considerations, and using IS 800/IS 801 LRFD misses the torsion design entirely.

This leads to the structures being extremely under-designed as Solar PV MMS designs are predominantly governed by torsional instabilities-both wind induced and strength deformations and need to be designed by using the AISC 360-10 / AISIS100-96/16 codes.

Additionally, the existing codes do not help with the dynamic effects and aeroelastic instabilities – which in real life situations leads to the imposition of much higher loads than the calculated static loads on the structure. The memory of a recent thunderstorm’s devastating effect on a fixed tilt solar plant in North India would be fresh in the industry’s mind.

Wind tunnel testing at a reputed company with a scaled model of MMS is essential to deal with these kinds of uncertainties. It’s worth noting here how historically improper MMS have faced partial or full failures as a result of ignoring realistic wind influences. Wind loads and pressures on a structure can only be derived from an actual BOUNDARY

So, what needs to be addressed before selecting a Tracker supplier is: Is the technology reliable?

Is the technology durable?

LAYER WIND TUNNEL and not a theoretical calculation or any other type of Wind Tunnel.

Incorrect assumptions in surveying and levelling add more to the delays and project cost. Inadequate knowledge and testing of soil strengths add to hindrances in execution. Let’s look at Solar Trackers in particular.

The General view is that Solar Trackers are a relatively simple technology to implement - make a pivot, get a screw jack or gear, fit a motor, get a controller to move it and sort of copy an existing MMS design – and a single axis tracker is launched!

Margins seem nice, business is assured, so why not make one.

Unfortunately, it is not that simple!

The fact is that ALL the leading Tracker brands across the world, including in India, are PURE PLAY Tracker technology companies. All these companies have a very strong technology and product development ETHOS. With all new technologies, there are always a bunch of ‘cheaper’ and ‘me too’ options available in the first couple of years. These companies sell a lot, but their offerings break down a lot. After the dust has settled, the best engineered technologies remain.This is a classic TECHNOLOGY PRODUCT Cycle.

The success of a Tracker solution depends on its (a) Mechanical components and (b) Electronic control components.

The Mechanicalcomponents mainly comprises of the bearings, the MMS and the fasteners.

It is assumed that bearings will last for

more than 50 years, incurring no O&M costs – but does test data validate this assumption?

The electronic component is rarely assessed. However, the gain delivered by the tracker by efficiently tracking, stowing, shadow handling and backtracking depends entirely on the electronics and the algorithms.

The decision, more often than not, is based solely on MMS Weight and therefore total cost ONLY. For example, Supplier Xquotes MMS weight of 50 tons. Another established supplier Yprovides 60 ton MMS. Now, Y has already installed plants, has a solid track record and has a bankable tracker solution.

So what doesXknow that Y does not, which allows a >15% reduction in MMS weight from supplier X? NOTHING! The truth is - It is not possible to reduce the weight of the MMS beyond a certain point without compromising on the design integrity Add to this an equally important factor in selecting a tracker – not related to Technology and design – but to Delivery time and installation effort. Installation time required at site and O&M costs also need to be considered in depth, but are often ignored.

Both these have a direct impact on the ‘GO LIVE’ date of the project. Even a delay of a month means significant losses in generation income. More often than not, even though a ‘cheap’ technology is selected, the saving in CAPEX gets wiped out in construction delays (and related generation loss).

And since the above points are subjective, based on very preliminary assessments, some tangible indicators for buyers could be Does the company have an IE bankability report?

Does the company have a proven track record?

Panasonic’s Photovoltaic Module HITTM Adopted for Toyota Motor’s New Prius PHV Panasonic Corporation today announced that it has recently developed the “HITTM Photovoltaic Module for Automobile”, which was adopted for the new Prius PHV released in February 2017 by Toyota Motor Corporation (hereafter Toyota Motor). In addition, Panasonic’s automotive prismatic lithium-ion batteries were adopted for the drive batteries, as with the Prius PHV that was released in 2012.

P

anasonic Corporation has worked on the development of new applications of solar cells through the effective use of high performance and high reliability technologies and know-how that have been accumulated through the development, manufacture, and sales of photovoltaic modules for residential, public and industrial use.

Panasonic’s solar cells have a unique structure that combines a crystalline silicon substrate and an amorphous silicon film, and feature high conversion efficiency and excellent temperature characteristics. Conventional automotive solar cells can output up to several tens of watts and have been used only for the auxiliary charging of 12 V batteries and ventilation power sources for parked cars; however, the use of the features of Panasonic’s solar cells allow a high

output (approx.180 W) in a limited area on a car’s roof, enabling the charging of the drive lithium-ion batteries as well as 12 V batteries, resulting in a possible extension of an EV’s travel distance and increased in fuel economy.

Furthermore, Panasonic has developed technologies to laminate three-dimensional curved glass to match the new Prius PHV’s elegant body design, achieving the installation of modules on the roof without impairing the advanced design. This will eventually contribute to the improvement of the vehicle’s environmental performance. Panasonic will make efforts to expand the use of the “HITTM Photovoltaic Module for Automobile” and contribute to the achievement of an environmentally friendly society in the automotive as well as the housing and industrial fields.
