Editor's Note Dear Readers, The U.S. International Trade Commission (ITC) has issued its longawaited recommendations on trade action on imports of solar PV cells and modules that includes quotas, tariffs on crystalline silicon solar imports. Ultimately, these are only recommendations and it would be interesting to see what action the Trump Administration takes on this recommendations. While the industry is divide over the impact the US trade restrictions, if any, will have on the PV markets globally. The optimist see the rapid decline in PV generating cost to trigger worldwide demand for solar panels and modules, enabling the global PV market sales to stay at the same level as recorded in 2017. While the pessimists believe that the global market demand would trend downward in 2018. Back home, in a significant development India’s total renewable energy capacity crossed 60,000 MW in the September quarter. Out of this, wind power’s total capacity was 32,701 MW. Solar groundmounted segment’s capacity was 13,982 MW, while rooftop category had a capacity of 790 MW. With energy demand growing exponentially countries like India have experienced energy shortage and lack of energy for decades. Enter microgrids, which are essentially small, independent grids that can generate power, distribute it locally and control it, all without having to join a main power grid. Naturally, microgrids have opened up new opportunities for rural and even urban communities, providing cleaner energy at low costs because microgrids can be hooked up to energy sources such as wind, solar, hydro, geothermal and others. Additionally, since the distance between power generation and areas of usage are smaller, less energy is wasted. The cover story accesses the demand for microgrids in India. The advantages, opportunities and constraints for their growth. The writer further elaborates on how India can set an example for the rest of the world in achieving access to affordable energy through microgrid solutions. The 2017 Intersolar India Exhibition is running December 05-07 at the Bombay Exhibition Center, Mumbai highlighting key technological innovations and ongoing transformation of India’s solar firms. So be ready and keep your day to visit the most awaited exhibition and yes don’t forget to drop at our stall.

News & Views PM launches `16,320-crore ‘power for all’ project The Narendra Modi government, which started its ‘power for all’ campaign in rural India with the Deen Dayal Upadhyaya Gram Jyoti Yojana (DDUGJY), is continuing its campaign, with the Prime Minister launching the Pradhan Mantri Sahaj Bijli Har Ghar Yojana — Saubhagya.
holds. Access to energy is central to development and this initiative to expedite that access is strongly positive for growth.
Saubhagya is meant to ensure electrification of all willing households in rural and urban areas.
Under the Deen Dayal Upadhyaya Gram Jyoti Yojana, the government had decided to electrify 18,452 unelectrified villages within 1,000 days, by May 1, 2018. Today, there are only 3,000 unelectrified villages left in the country, Modi said.
Launching Saubhagya scheme, Modi said: “There are over 4 crore households in the country without electricity. That means almost 20 per cent of all 25 crore households are devoid of a basic necessity like power.” The government is targeting the completion of household electrification by December 2018. Industry observers believe that this represents a natural transition of government policy from electrification of villages to connecting house-
On Saubhagya scheme, Kameswara Rao, Leader - Energy, Utilities and Mining, PwC India, said, “The last-mile connectivity has always been a challenge, with households facing high con-
nections costs, and States facing higher supply costs. This attempt addresses both, by funding energy-efficient equipment.” The government also plans to provide solar power packs of 200-300 Watt peak capacity with battery bank for unelectrified households in remote and inaccessible areas and also provide five LED lights, a DC fan, a DC power plug as well as maintenance for five years
Small & medium Wrong classification leaves solar sized solar man- developers stranded ufacturers float A new interpretation of customs “It is a matter of wrong classificarules has jeopardised India’s solar tion,” said Anand Kumar, secretary industry body energy projects, with officials in the MNRE. “They are sorting out A group of small and mediumsized solar module manufactures have formed a new industry association by the name North India Module Manufacturer Association (NIMMA) in a bid to voice their concerns. “We found that the existing solar associations in India are finding it difficult to cater to the needs of small and medium size solar modules manufacturers, who have some unique problems and issues. NIMMA is the end result of the same,” said Manish Gupta, President, NIMMA. NIMMA will work with government authorities and other national and international solar organizations the statement said

demanding payment of import duties on crucial inputs that were previously always shipped in without any levy, leaving developers stranded as 90% of these modules are not produced in India.
This has held up about 1,000 containers of solar modules at the Chennai port, affecting almost all the leading developers because customs authorities have suddenly started classifying solar modules as “electrical motors and generators,” which attract a levy of 7.5%, plus 2% education cess and 1% secondary and higher education cess, industry executives said. The Ministry of New & Renewable Energy is seized of the matter and has written to the finance ministry.
the matter. I’ve talked to the board member concerned.” Developers said they face severe harassment, which can hit loan repayment and make it difficult to achieve targets. They said customs authorities in other ports have also misinterpreted rules for solar equipment in the past. “It is simple arm-twisting,” said a leading developer. “At least $5-7 billion worth of solar modules must have been imported over all these years without attracting any import duty. Suddenly, some spirited customs officials have decided to reinvent the wheel. We have Rs. 375 crore worth of goods which are stuck with a duty implication of over Rs. 30 crore. It is sheer harassment with ulterior motives.” www.supersmartenergy.com

He further said that the project used modules from Telanganabased manufacturer Radiant Solar. It also used 32kW sting inverters made by ABB.
Since the project was completed Adtech has received enquiries for more than 50MW of other floating PV projects, Narayanan added.
The floats were designed with ferrocement, which involves applying reinforced mortar or plaster over layers of metal to create a hollow structure. Narayanan said ferrocement makes the project very stable.
Floating solar projects can often generate more power than ground-mount solar systems due to the water body’s cooling effect on the modules. They can also preserve water levels through shading.
He added: “Our company has been specialised in making ferrocement platforms and floating structures for the last 20 years. The ferrocement platforms are guaranteed for 50 years life.”
Solar Energy Corporation of India (SECI) is also planning two 10MW floating PV projects in Kerala and Andhra Pradesh with the floating structure and anchoring designed by Arka ■
Jakson Group to increase its solar manufacturing capacity to 1.5 GW The Noida-based Jakson group plans to increase its solar manufacturing capacity to 1.5 gigawatts by 2020 in line with the government's objective of achieving 175 GW renewable power generation by 2022. The company, that has a railway contract for equipping trains with solar panels, did a successful pilot recently for a DEMU in Delhi. With the increase in its module capacity and a foray into solar cell manufacturing, the company wants to position itself as an energy and engineering company, said Sameer Gupta, chairman and managing director, Jakson group. Though the company diversified into solar business in 2010, power backups and diesel gensets still comprise a large part of its revenue. About 40 per cent of its Rs 2,700 crore revenue comes from PowerGen and distribution business where it is a leading player. The company is making an investment of Rs 700 crore in the new solar module manufactur-
ing plant in Gujarat. According to Gupta, the investment would be made in two phases. In the first phase, the capacity of 500 MW of solar modules would be set up. In the second phase, another 500MW of solar module manufacturing and 250MW of the solar cell would be set up. The total capacity would be 1GW of modules and 250MW of cells. It currently has 70 MW of capacity at its Noida plant for manufacturing mono and polycrystalline modules besides an installed capacity of 500 MW of module mounting structures. Gupta said they were also targeting the export market, which includes countries in the West Asia and Africa for EPC business. They have already appointed 12 dealers for selling modules and offer retail solutions in the export market. The group also owns and operates three solar IPP with a total installed capacity of 60 MW ■

ISA to be a legal entity, to tap 1000 GW solar energy by 2030 The International Solar Alliance (ISA), jointly launched by Indian Prime Minister Narendra Modi and then French President Francois Hollande on the first day of COP21 UN Climate Change Conference in 2015, is set to become a legal entity, an official release announced this recently. As of date, 44 out of 121 countries have signed the ISA Framework Agreement. Sixteen nations have submitted the formal Instrument of Ratification. They include Bangladesh, Fiji, France, Ghana, Guinea, India, Mauritius, Seychelles, Somalia and South Sudan. "The ISA is going to a
legal entity on December 6," Anand Kumar, Secretary, Ministry of New and Renewable Energy, was quoted in the release. The release further mentioned that the ISA is working for tapping 1,000 GW of solar energy by 2030 in its partner countries. With the postponement of the first ISA summit in India, a new date is likely to be announced soon. Likewise, the second edition of Global Renewable Energy Investors Meet and Expo -- RE-INVEST 2017, scheduled next month in Greater Noida in India has been postponed to April 19-21 next year. France is India's partner in both the
ISA summit and REINVEST 2017. ISA is the first international intergovernmental treatybased organisation headquartered in India. The ISA's main objective is to undertake the joint efforts required to reduce the cost of finance and the cost of technology and mobilise more than $1,000 billion of investments needed by 2030 for the massive deployment of solar energy.

KERC directive on tariff, a setback to the wind industry Karnataka’s electricity regulator has refused to approve the power purchase agreements (PPAs) for wind power projects that were commissioned before March 31, 2017, without a fresh tariff reduction of 17% to Rs 3.74/ unit. The decision would impact 242.5 MW of wind power plants with a capital cost of about Rs 1,350 crore in the state. Apart from Indian companies such as Suzlon and Inox, the decision would adversely affect projects of foreign companies such as Siemens Gamesa and Green Infra. The decision comes shortly after the Solar Energy Corporation of India managed to get bids as low
as Rs 2.64 a unit in the second competitive bidding for wind energy of 1,000 MW. After the first such auction held in February, where wind tariffs dropped to Rs 3.46/unit, there were a series of issues across Andhra Pradesh, Karnataka and Rajasthan where state-owned discoms wanted to renegotiate previously agreed prices. “While the IPPs have already signed PPA’s for these projects with the state’s discoms, the recent tariff revision by KERC, has hurt the investor confidence in the state,” said Ramesh Kymal, Chairman and MD, Siemens Gamesa Renewable Power ■
said, " We were able to achieve our targeted returns at such a low tariff through a combination of factors, including: ownership of critical development assets in a site with strong wind resource, strong relationships with global suppliers of lowest cost of energy technology, cost economy of scale associated with a single 200MW project, efficient sourcing of capital, sophisticated and innovative contracts and low off take risks in terms of PPA and evacuation. We attribute this success to our disciplined focus on building project development, financing, construction management and asset management capabilities." ■

DEIF’s Solar Solutions
cross the world, the need to make the energy portfolio environmental friendly is a pressing need. Among the renewable sources, Solar power is gaining momentum in India with the push given by government and the abundant solar potential in India. The increasing demand is driving down the cost of solar energy which is attracting more and more investment in this sector.

While the investment and increasing of Solar share in the energy sources is fully justified, it is also equally important to have efficient controls that will enable solar penetration to maximum possible extent including the possibility of exporting the excess power back to the grid. Challenge with solar In a contemporary system, solar power can only be utilised as long as the utility supply is available. In the absence of utility, solar power can no longer deliver the power and the diesel generators come in to deliver the backup power. The Solar systems are not geared up to supply power along with the diesel or gas genset as the load sharing between the two groups is a challenge. This leads to burning the fuel (diesel/gas) for the genset to take the entire load for the duration for which the utility is absent, in spite of solar power

source being available. DEIF’s answer challenge
DEIF with its experience and expertise in the field of power generation control solutions; has come up with an innovative solution to this challenge. DEIF introduces the Automatic Sustainable Controller (ASC), a solution that provides integrated solution for systems with utility, diesel and solar power source. The system provides an interface between the diesel/gas genset and solar, with or without presence of utility power - a solution that enables you to share the load between solar PV cell and diesel/ gas genset with maximum solar penetration, thus resulting in maximised savings even during utility failure. DEIF solutions being costeffective balance your economy and conserve the environment as they are highly efficient. A solar system consists of series of PV cells connected to their respective inverters. DEIF’s solar controller is connected to the master inverter or central control point of the group of inverters and interconnected among Utility and Genset Controllers through CAN
bus communication. DEIF’s solar controller serves as an interface between Solar source and the diesel genset controllers/Utility Power, namely Advanced Genset Controllers (AGC), over the CAN bus to adjust power output to meet the load requirement with solar system taking the maximum load share. When the utility fails, Genset start up to provide the reference and provide minimum load that will let it run efficiently and let the solar meet the rest of the demand. If the solar power output decreases due to bad sunlight, the deficit will be met by diesel/gas genset through the intelligent interface, thus ensuring reliable supply of power in all conditions. If the export of power from Solar is not demanded then the Automatic Sustainable Controller will restrict the solar generation to the desired limit. How much can you save? To get a glimpse of what you would be your minimal saving after installing DEIF’s solution, let us consider a simple real life example. On an average, considering power loss of up to 20 hours per week implies that in a year you can have almost 1000 hours of lack of util-
ity power. Considering that the diesel consumption normally is of 125 litres per hour (500 KW at full load) and assuming 1.5 $/litre as cost of diesel, for 1000 hours of no utility power, 187.5 $/hour is the cost for running a diesel genset for one hour. For 1000 hours you would spend 1, 87,500 $ and for running 2 genset, the total spending will be 3, 75,000 $ on fuel cost alone. In addition to this, the cost for handling the fuel, managing resources, maintenance of genset, gas emissions, and environmental
setbacks add to the overheads. On the other hand, DEIF’s solar solution enables you to use solar power even in the absence of utility with high solar penetration. Say with a 60 % solar penetration you can run just one genset and save on fuel cost of the other in the period of utility failure which implies a saving of 1, 87,500 $. Using solar for the additional period of the year can make that period also further green and help maximize the project’s over-
all return on investment. DEIF’s solar solution will thus prove to be a boon to India’s evolving solar sector ■ Contact us: For further information or any other questions you may have, don’t hesitate to contact us on (+91) 22 4245 2000 or please feel free to write us at India@ deif.com.

"We are confident that within the next few years RenewSys will be amongst the top 5 players in the solar industry in India"
.RenewSys is the first Indian company to produce 5BB cells domestically, could you elaborate more on the technology, its advantages and it’s impact on the performance of the solar PV system? In June, RenewSys, India’s first & only integrated manufacturer of Solar PV Modules & it’s key components - Encapsulants (EVA & POE), Backsheets and Solar PV Cells, became the first Indian company to launch the production of five Bus Bar (BB) Solar Photovoltaic (PV) Cells. The 5BB cells, part of RenewSys’ RESERV® range of solar PV cells,
30 SmartEnergy Nov/ Dec 2017
are being manufactured at our plant in Hyderabad using a world class automated European PV cell line in a state of the art clean room facility. Increasing the number of Bus Bars (BBs) in a photovoltaic cell lowers the series resistance and thus increases the current. Eventually, the PV cell power increases, which improves the overall module performance. Apart from the advanced technologies such as PERC, PERT and IBC, increasing the number of Bus Bars, is an attractive technology development to produce solar panels with higher efficiency.
RenewSys recognizes that quality raw materials, commitment to R&D and competitively priced products are all crucial to the solar industry, and affect the performance and success of PV solar power systems.
.Do you see more players entering into manufacturing of 5BB cells and the widespread adoption of the 5BB technology in modules in the future? We are seeing a steady rise in the number of Indian module manufacturers that correspond to the acceptance and demand for solar www.supersmartenergy.com
power in India and globally. When it comes to cell manufacturing however, one has to bear in mind that cell manufacturing is a high CAPEX industry in comparison to module manufacturing. Raw material availability is also a challenge, as silicon wafers have to be imported and business at all stages, from wafers to modules is extremely price sensitive. However, as the industry grows, and with support from the relevant authorities, an increase in cell manufacturing capacity may be expected and is also much needed. In the long term vertical integration and the rise of local manufacturers for cells and other components will help bring the cost down for module manufacturers through ‘Just-in-Time’ inventory and other logistic benefits. As far as the use of 5BB modules is concerned we believe that 4BB
and below will phase out and 5BB will become the prevalent standard module in use.
.In addition of India which are the other geographies that you are looking at as potential growth market for these products? Like I mentioned earlier RenewSys manufactures PV Solar modules/ panels as well as Solar PV Cells, EVA, POE and Bus Bar insulation sheets. We began operations in 2012 and since then have not only managed to set up global operations and supply, but also establish ourselves in advanced markets like Europe and USA where we continue to make steady inroads. This has been made possible due to various contributing factors. The support and heritage of manufacturing excellence that we inherited from the Enpee Group,
has been a guidepost in setting up and maintaining world class manufacturing facilities at Hyderabad and Bengaluru. We have also invested significantly in developing a robust talent pool, acquiring state of the art European machinery, and in world class R&D labs of our own.
.Please tell us about the manufacturing process of your best in class DESERV™ modules and what are the steps taken to ensure the quality? RenewSys manufactures a range of reliable, competitively priced, certified modules complying with IEC standards under the brand name ‘DESERV’. Our modules are designed to deliver optimal performance in adverse conditions and are fortified with PID resistant cells, and Encapsulants and Backsheets. In

Expert Insight fact, we only use Encapsulant and Backsheet that has been manufactured in-house at our Bangalore division for all our modules; this further enhances the performance of our modules. Our current module capacity is 300 MW and the modules produced suit applications from small home lighting requirements to utility scale mega power plants. The PV modules come in configurations of 36 Cells, 48 Cells, 60 Cells and 72 cells. We are in the process of expanding our capacity and additional module lines with the latest European technology. This will take our capacity up to approximately 350 MW. Our module manufacturing process is completely automated and we perform rigorous and thorough in-house testing of the modules manufactured for compliance with IEC standards. We are able to ensure quality modules that generate more electricity i.e. have higher efficiency due to the use of only A+ grade cells and ensuring that all modules have positive tolerance values. Apart from a wide range of standard mono and multi crystalline modules, we also produce the ‘Prime’ and ‘X-Prime’ Series of modules designed specially to suit applications like pumping due to their voltage output. These modules have been appreciated by small business owners worldwide. We have also just launched two specially designed modules, a 355 Wp module that is currently under certification made with standard mono cells and a 340 Wp module made with standard multi-crystalline cells that we feel will grow in demand going forward. When setting up our module manufacturing process, we leveraged a combination of the feedback and insights we collected from the market and our partners, a detailed third party study conducted on the performance of modules in various climate zones

in the Indian Subcontinent and the experience and expertise of our specialised in house R&D teams. These findings and our dialogue with industry partners globally helped guide us in selecting technology and in formulating processes to ensure that our modules perform reliably and exceed expectations. Our in-house R&D team has also worked on specialized designs and customisations to help incorporate solar PV panels in various projects efficiently. One such recent example that comes to mind was the design of vertical modules for a solar street lighting project where we customised the modules to vertically fit the pole and the modules were the same size as the pole. With modules another significant aspect that has an impact on the life and performance of the module is the post production care. RenewSys ensures that all our modules pass the three stage laminator process. This prevents the module temperature, post lamination, from dropping suddenly and there by prevents the formation of micro cracks. We have also invested in an automated humidity chamber that among other aspects ensures that the module ‘cures’ in-line and has brought down the curing time per module from eight hours to four hours. An automated binning system sorts out modules with positive tolerance and these are then packed and stored at our automated stacking facility. This facility is the largest of its kind in India and has paved the way for seam-
less raw material and finished goods handling and storing at our Hyderabad manufacturing facility.
.How do you ensure that everything goes as per your promise of delivering quality modules to your customers? RenewSys has unparalleled in house R&D facilities in India at both our manufacturing plants – Hyderabad and Bengaluru. While the facility at Bengaluru specialises in polymer research and testing, the R&D lab at Hyderabad specialises in cell and module testing. For modules, we have a comprehensive module testing facility – an in house ‘Reliability Lab’ – a one of its kind facility that is at par with global third party certifying labs and is capable of testing modules in climatic and environmental conditions up to 2- 2.5 times those required for international certifications. It consists of 7 climate chambers and is managed by a talented, diligent R&D team. We carry out comprehensive tests on our modules routinely to ensure that all our manufacturing systems and processes are exceeding performance expectations and delivering quality modules. Additionally, we leverage our expertise in component manufacturing and develop Encapsulants and Backsheets to suit the demands of varied climatic and geographical in field conditions. These are then incorporated into our modules and are tested in both our Reliability Testing labs as well as in our own solar power plants, located within the premises
of our manufacturing facilities.
.Your views on recent antidumping petition against equipment coming from China, Taiwan and Malaysia? Do you see any impact on the appetites for setting up cell production in India? Much like other countries, who have implemented protective measures for safeguarding their market from cheaper imports of finished products, India will also see a rush in locally manufactured goods as well. This move will only strengthen the Government’s ‘Made in India’ initiative. Considering the rate at which Indian domestic solar manufacturing installed capacities are expanding, it will provide Indian manufacturers the necessary scale complimented by a favourable manufacturing policy regime, thereby becoming globally competitive within a span of 4 to 5 years.
. What according to you are the challenges that the solar sector in India is currently facing? Can a flourishing domestic PV cell and module manufacturing industry address some of these challenges and help in the growth of the solar sector in India? There are three key challenges that the solar industry in India is facing. The first is the availability of raw materials. Currently they
have to be imported and the price is sensitive to changes in global markets. The second is the logistics cost, landing goods from China to India is often more economical than transport within India, say Mumbai to Delhi for instance. Last but not the least, is the availability of cheap funding for manufacturing companies and overall sops for exports. For the solar industry in India to truly flourish, some handholding is required as the industry is at a nascent stage of development and needs some time before it can compete with global players.
.How has been RenewSys’ performance in its core EVA Encapsulant CONSERV ™ and Backsheet manufacturing? Where do you see the future growth for the company coming from? We produce Encapsulants – EVA & POE CONSERV® (1.2 GW) & Backsheets PRESERV® (1.8 GW) Backsheet. Both of these are critical components of a solar panel. RenewSys manufactures these at our Bengaluru facility as per international standards, using top of the line European equipment. We apply the same rigour and quality parameters to our Encapsulant and Backsheet production as we do to our best in class modules. We have a state of the art ‘R&D Lab’ and ‘Reliability Testing Lab’ for Encapsulants and Backsheets
at our Bangalore Facility. It is the quality and performance of these products that has helped us enter the competitive global market for Encapsulants and Backsheets and grow our customer base in the Middle East, Europe, USA, etc. RenewSys also holds the distinction of being the only manufacturer of POE in India. The special formulation of our POE suits its use in Glass –to- Glass modules, due to its anti-thermal creeping property. We also provide advanced level of customisations for our Encapsulants and Backsheets to suit modules of different varieties.
.Where do you see RenewSys in India in the next 3 to 5 years from now? Among the players in the Indian solar industry, RenewSys is already a well-known and reliable name, especially from the perspective of quality, performance, talent and in- house testing facilities. We are confident that within the next few years RenewSys will have established ourselves among the top 5 players in the solar industry in India. Our global network will further help RenewSys strengthen our exports offering and reach out to swiftly to growing markets across the globe, making us a leading manufacturer and exporter of modules

SOLAR ENERGY Paving the Way for a Brighter Future Authored by: Gajanan Nabar, CEO, CleanMax Solar
eeping in line with the Government’s ambitious target of achieving 100 GW of solar energy by 2022, 2017 is being touted as a landmark year for the solar energy sector. As we flourish in the wave of sustainable developing nation, corporates are becoming increasingly conscious about their environmental footprint and thereby came the RE100 vision with focus on carbon neutrality. At the forefront aiding this growth is CleanMax Solar, India’s largest on-site rooftop solar power developer. As a leader in the rooftop solar space with a market share of 24 per cent (Bridge to India report 2017), we are continually working along with corporates and PSUs to help materialise the vision of a solar powered nation. Set by Prime Minister Narendra Modi, the target of 100 GW solar power by 2022 of which 40 GW is rooftop solar is an ambitious one, but given the conducive eco-system and necessary regulatory environment, it is achievable. We are seeing a steady growth among
34 SmartEnergy Nov/ Dec 2017
corporates wanting to pursue solar energy for their needs and this has extended to a number of PSUs who are opting for sustainable operations. Our unique OPEX model has contributed to the rise in solar projects across the country. OPEX model has made the process of adopting solar energy risk free, hassle free and investment or CAPEX free, as the adopters need not invest in the solar plant. In this case, corporate entities are at a huge advantage, as not only do we help them convert dead assets such as rooftops or carports into a monetised mechanism, but also corporates are able to enjoy power which is 20-40 per cent cheaper than grid tariff. All in all, under OPEX, companies do not have to invest in a non-core asset, and at the same time are able to enjoy power at a significantly low tariff. Although adoption of solar power is a highly lucrative proposition, there are challenges that are part of the equation. Net metering, for instance, is one such challenge. Net Metering is
a mechanism of selling the surplus power back to the DISCOMS (distribution companies) when users don’t have adequate load; for instance, off-days for factories and summer vacations at schools. In this case, the meters measure the power exported to the grid and the consumer is given credit for the exported power in their electricity bill. Although we have seen positive developments in terms of regulations, we are still facing challenges in implementation. Many state regulations have dictated artificial restrictions on the size of the plant, which can be installed with net metering, beyond a technical necessity. Net metering approvals are also a slow and cumbersome process and are a hurdle for corporate entities to adopt solar energy at a large scale. Despite many states having created net metering policies, implementation of the same has been slow and is still constrained by limits. Tamil Nadu, for example, does not allow net metering among high-tension consumers, who are the largest consumer base for solar energy www.supersmartenergy.com
in the state. In Maharashtra, the state government has placed an artificial capacity cap of 1 MWp. As per this, even if the consumer has the space to accommodate more than 1 MWp system, the existing net metering policy would allow only 1 MWp system to be installed. While the central government is on the right track with its target of 40GW rooftop solar energy, more can be done to frame a standardised policy across the country. This will not only help expand the solar energy base, but also help meet the ambitious national target.
omy. Trade relationships and other geo-political challenges come into play. However, an economic factor that does play a big role in the determination of prices and in-turn, the value proposition of solar power is, the falling solar bids. In the recent times, overaggressive bids have become a popular trend. This however, poses a real threat which may
cause derailment of solar energy projects in the years to come. The drop in solar power tariffs, while a great proposition, may be beneficial only for a short stint. As corporate entities reap the benefits of these savings, they may fail to look at the long term hard realities
Another challenge that the solar industry faces is the constant dip in solar panel costs. Recently solar power has become one of the cheapest new source of power in India (BTI India Solar Compass 2017 Q2), since solar panel prices have fallen drastically over the last few years. What this has done is, created unrealistic expectations among customers that prices will fall further and thus delays the adoption of solar power, which is a risky trend. In fact, earlier this month solar panel prices rose by 2-3 cents (USD dollar) per watt peak, which is the first of its kind in many years. Solar industry is dependent on imports and that is one element which is beyond the ambit of the Indian econ-

View Point of the sector. Indian firms, although unknowingly, may give out an underwhelming quote. These quotes floating in the market, may be very aggressive and are based on relatively aggressive assumptions, which may not hold true in the current scenario. In some cases, there may be no room for any contingencies or any turn of event. Hence, it is advisable to make a move with caution. Overall, more clarity on vision, alignment of DISCOMS with state governments and boards with central government, will certainly help achieve the target of being a solar powered nation. Moreover, if government was to offer continued incentives at the central and state level, it would boost the demand for solar energy. A prime example of such incentives is the Karnataka Electricity Regulation Committee (KERC) policy, focussing on adoption of open access solar power. The KERC policy has found favour among corporates for procuring solar energy from our 60MW farm. Under the existing policy, transmission and distribution charges have been waived off till March 2018, which is an additional saving for the company who are already enjoying relatively cheaper energy than grid tariffs. In fact, Karnataka has overtaken Gujarat to become the third highest producer of renewable energy after Tamil Nadu and Maharashtra. According to PwC, more than 10,000 MW of electricity will be saved by avoiding T&D losses in 2022 alone. Further, commercial benefits in avoiding investments in transmission systems are huge.
Most importantly, rooftop solar power reduces the dependence on grid power & diesel generators, and is a long-term reliable power source for consumers. As we work along with the Government’s vision, we are heading into the next phase of our operations. With the backing of private equity giant Warburg Pincus, who have invested USD 100 million in CleanMax Solar, one of our main goals is to maintain our leadership position in the rooftop solar developer space as well as increase our open access solar market. Under the existing open access farm policy, we own and operate a 30MW solar farm in Tamil Nadu and Karnataka and are working on another 150MW farm. We are also working towards our long-term goals of overseas expansion and are looking at South East Asia and the Middle East, and have already opened our first office in the UAE. Our operations here will begin shortly and we will be following the OPEX model in order to attract customers to adopt solar energy. Our plans for the region are also in tandem with the UAE government’s 2021 vision of achieving
30 per cent solar dependencies. As a natural progression from providing solar energy, we are exploring energy storage solutions, which not only compliments our offerings, but is economically viable as well. Solar power storage can be made possible through batteries which are used to store electricity generated by the PV solar power system. By integrating battery backed solar power systems, we will also be able to avoid loss of generated energy and ensure optimum use. 2017 has indeed been a landmark year for solar energy and we are witnessing a growing number of installations. With such tremendous growth, according to recent reports, 10 GW of new solar capacity will be added to India’s energy portfolio during the 2017 calendar year. With an increasing number of PSUs and corporates adopting solar energy to power their operations, the sun is definitely shining bright on the sector and tapping into the tremendous potential of the industry, CleanMax Solar is looking onto viable growth opportunities, in India and abroad

Anand International is exclusively involved in providing the E-Beaming solutions for the Wire and Cable Industry.
.Elaborate on E-beam technology? Its applications? And advantages of Electron Beam Irradiation? Electron Beam Processing is the method for producing chemical and physical changes in various substances by exposure to ionizing radiation in the form of energetic electrons. Electrons are particles possessing a negative electric charge, which is an integral part of every neutral atom. During this process several different effects may occur depending on the material being processed, the dose or amount of treatment that is being applied. These effects include, but are not limited to, Cross linking, Polymer Degradation, Sterilization, Pasteurization, and Vulcanization. E-Beam differs from other radiation processes in that it is highly controllable, and can be turned completely off with no residual effects. This Technology caters to various applications which include Wires & Cables, Heat Shrink Products, Degradation of Fluoroploymers, Sterilization of medical products, etc. Talking about the advantages, this technology is well accepted throughout the globe as the pro-
cess is easily controllable with very tighter tolerances. It gives high productivity which enables one to reduce the Operating costs and also increases the life of a cable. The process does not require any additives and does not generate Hazardous chemical by-product. This technology is Green Technology which helps to enhance product life and performance in adverse conditions, very efficient and enable us higher throughputs.
.What are the factors that need to be considered while manufacturing cables for solar and renewable applications? Energy delivered from a Solar PV system is not only dependent on the efficiency of the module but also on other system components like DC Cables, Connectors & Junction Boxes. Solar DC Cable is technically a very special application. Solar DC Cables needs to perform in an extreme environmental conditions and are generally exposed to high UV radiation, high temperature, moisture, humidity, dirt and microbial attacks. In addition these cables are expected to perform for a targeted service life of more than 25 years. Exposure to high UV radiations significantly affects the cable properties. Hence, sheathing material used should be highly UV resistant. Currently red and black coloured sheathing material is used. It is recommended to use black coloured compound with enough black carbon content that will help absorb more UV radiation and convert it into

heat. The manufacturers should select EBXL /Chemical Cross linkable of Insulation & Sheathing material which comply with EN/ UL/TUV requirements. There is a New European Standard EN 50618 published for Solar DC Cable, this standard specifies cables for use in Photovoltaic (PV) Systems. The testing requirements in EN 50618 are more stringent. The EN 50618 standard requires cables to be low smoke halogen free, flexible tin coated copper conductors, single core power cable with cross linked insulation and sheath. There are two processes adapted worldwide to crosslink the cablesE-Beam cross linking and Chemical Cross linking. In Chemical process the polymer need to be extruded at high temperature (up to 220C). Due to high temperature the polymer is degraded to some extent and over a period of time it becomes hard, porous and it eventually cracks whereas E-beam crosslinking compounds are extruded at lower temperature and cross linking takes place at ambient temperature, which keeps the polymer soft and elastic to achieve the desired life of 25yrs.
.What are the advantages of E-beam cross linked solar cables? The Electron Beam Cross Linked (EBXL) Solar Cables offer superior
performance in extreme Environments. The Cable can continuously operate at 1250C temperature. It has Better UV & Ozone resistance and a improved weather resistance in adverse conditions. It has an improved Oil, Chemical and crack resistance. It also possesses improved Mechanical properties of the cable at elevated temperature conditions. It also offers better aging resistance compare to the chemical cross-linking.
.With tremendous growth and government emphasis on solar and wind, what is the growth that you are looking for from this sector? The Government under the leadership of Shri Narendra Modi has set a highly ambitious plan, The Jawaharlal Nehru National Solar mission, to reach solar power generation to 100 GW by 2022. Currently the solar industry due to competition and reduction in tariffs is under tremendous pressure to sustain in a highly competitive environment. Though reduction in prices of solar module, accessories and components has help OEMs and EPCs in reworking the project cost to sustain. The Government is working favourably in funding solar projects and encouraging private players for investments. Foreign direct Investments are also happening. Amid all this positive developments we are expecting
E-Beam differs from other radiation processes in that it is highly controllable, and can be turned completely off with no residual effects.
20-25% growth in this segment
.What differentiates the E-beam cross linked solar cables manufactured by Anand International from those already available in the market? ii Cables currently being produced are as per IS/UL/TUV/EN standards. Very few manufacturers in India have E-beam facility are able to supply EBXL Solar DC. ii Rest other manufacturers are using chemical crosslinkable materials and XLPE/PVC. ii We use E-Beam crosslinkable XLPO Low Smoke Halogen Free Polymer Compounds (LSZH) specially develop and recommended for Solar PV cable. Compliant to latest Standards EN-50618,2014.

Residential Rooftop Solar
3 A’s of Adoption An ear-to-the-ground analysis conducted by interviewing numerous homeowners reveal interesting insights eliciting non-adoption of residential rooftop solar. Authored by: Aniket Baheti & Erich Nussbaumer
n the current scenario, residential customers do not look forward to solar systems beyond the savings they offer on the electricity bills. An extensive field study revealed the barriers which prevent homeowners from going solar. The new year’s eve of 2016 presented a pleasant gift to the grid connected rooftop solar sector in the form of 30% subsidy funded by a Rs 5,000 Crore support fund, scaled up from the previous sanction of Rs 600 crores. The next six months witnessed majority states adopting net metering as an incentive to boost residential rooftop in their regions. As a nation aiming for a 100 GW installation target, 40 GW through rooftop installations, India has only been able to install 1.2 GW rooftop solar out of total 12.5 GW solar capacity installation till date. Achieving a 32x scale to current installation within next 5 years would require movement of solar industry’s adoption curve from its present early adoption stage to the growth stage. A team from Sangam Ventures,
42 SmartEnergy Nov/ Dec 2017
an early stage venture fund that invests in startups building sustainable energy solutions aimed at inclusive development and creation of communities that are resilient to climate change, set out on ground to dig deeper into reasons for non-adoption of residential rooftop solar. The team travelled to Jaipur, Nagpur and Vijayawada to understand customer outlook towards solar & collect qualitative feedback about existing residential rooftop solar market. The choice of cities gave the team a range of customer profiles to study and helped form a high level understanding of the barriers to adoption of solar by individual homeowners. The customers varied on income levels, awareness about solar, access to roof, education levels and on many other fronts. Demographic differences represented itself in the importance homeowners placed on various aspects of rooftop solar solutions. Each customer interaction was aimed at gauging current awareness about solar rooftop solu-
tions, its savings potential and costs involved. Awareness: The awareness about rooftop solar system is limited to the amount of public broadcasting done by local government at city level. Nagpur homeowners, for example, were already introduced to one application of solar in the form of rooftop water heaters. There was, however, very little understanding of how a solar PV system really works. The individual components that make up the system is not a common knowledge and customers were not much aware of companies to approach for installing solar on their rooftops. Though solar PV system requires very low operations & maintenance efforts, customers were concerned about the long run functioning of the systems. In absence of concerted efforts towards educating customers by local renewable energy agencies and solar companies, awareness remains to be a challenging issue to be solved. Affordability: Depending on the range of awareness, customers www.supersmartenergy.com
were in different stages of adopting a solar solution. High upfront costs are a no-go even for households who are at the advanced stages of awareness. Financing schemes available with public sector banks are in the form of extension on home-loans which keep out the customers with not-so-great credit profiles. State sponsored incentives are a ray of hope in affordability to adopt solar but customers do not wish to own the responsibility of securing the approvals for the same. Solar solutions need to be made more affordable to price sensitive residential customers. Aspiration: In almost all customer interactions, solar never appeared to be a “wanted” product or service for the homeowners. The buck stops at the solar system not being a very exciting product
and the perceived benefit of owning a system didn’t make the customers want it. Investment into residential solar fails out to competing needs of customers such as ownership of air conditioner or two wheelers. Solar system on rooftop doesn’t grant an uplift in social status to those who are aware of solar and can afford it. Many homeowners in Jaipur, for instance, with access to flat rooftop would not trade off the access to terrace for installing solar simply because the perceived benefits don’t make a cut for decision making. Rooftop solar at residential level has a value add beyond just providing electricity from an alter-
native source. For certain regions, residential rooftop solar can act as a decentralized energy source that powers homes impacted by unreliable electricity supply from grid. Rooftop solar companies, often, pitch solar as a mechanism to contribute positively to the environment. A bulk of present customers only concern themselves

An increase in adoption of rooftop solar by residential customers will require multi-stakeholder
intervention from the solar ecosystem.

ness among residential prospects. Original equipment manufacturers should pass on the benefits of economies of scale at residential level to the end customers. Homeowners will aspire for solar system once they can clearly understand the value it offers for the entire household.

CGN-Dasheng has sold ten E.B.Machines in India so far, solar cable production appears to be the main purpose. CGN-Dasheng’s polymer business also is growing in India.
.How has the cross linking of insulation layer in wires and cables evolved? Why is it important and what are its benefits? Cross-linking of polymers with E.B.radiation is known since year 1950. The insulation layer in wires and cables gets cross-linked when exposed to the beam of high energy electrons meaning, molecular covalent bonds of long, linear chains of insulation material break down due to radiation and rearrange themselves in larger relative molecular mass in 3-D mesh structure. This is an advanced technology which replaces conventional cross-linking methods. After the irradiation treatment wire & cable performance improves sharply, particularly w.r.t. to the properties like tensile, thermal aging, temperature grading, abrasion resistance, UV resistance, extended life span etc. Such product can safely be used over prolonged period, in hostile environments like solar power plants, solar devices, coal plants, wind mills, nuclear plants and other applications like locomotives, automobiles etc.
.Shed some light on the E-Beam technology and the role it plays in cross linking of insulation layer in wires and cables? EB Machines consists of a system that can transform 3 phase grid power in to high frequency high voltage power. Components carrying this power is contained in a still vessels filled with pressurised insulating gas such as SF6 or CO2+N mixture. Within the same system is also located a system which is under high vacuum wherein electrons are generated by charging a tungsten filament. The high voltage is then applied to the electrons thereby accelerating them nearly to the velocity of light, thus creating a beam of high energy electrons. This beam is then brought out of the high vacuum zone to the atmosphere and is scanned over the product, which in this case is wire and

Cover Story Resurgent India faces the daunting task of providing energy access to its people mainly in the rural areas. To date, rural electrification and energy access has been tackled by succeeding governments through centralized electricity infrastructure delivery systems. Author Sneha Shah believes that effective, reliable and sustainable way to provide access to electricity in India is through Decentralized Renewable Energy
System (DRES) or distributed micro-grids. While the government through the National Policy on Renewable Energy-based Microgrids plans to establish 10,000 renewablebased micro- and mini-grid projects across the country.

ICRO GRIDS e Indian Villages!
Though the government has delivered significant progress on rural electrification in the recent past, a large number of rural households still have no access to electricity.
According to MNRE, a “Mini Grid” is defined as a system having a renewable energy (RE) based electricity generator (with capacity of 10KW and above), and sup www.supersmartenergy.com
plying electricity to a target set of consumers (residents for household usage, commercial, productive, industrial and institutional setups etc.) through a Public Distribution Network (PDN).
For example, in a solar microgrid, solar panels are connected with batteries and power is supplied. The concept is fast growing in Indian villages where the per capita requirement is quite low.
A ‘Microgrid’ system is similar to a mini grid but having a renewable energy based generation capacity of below 10KW. Micro and minigrids generally operate in isolation to the electricity networks of the DISCOM grid, but can also interconnect with the grid to exchange power. If connected to grid, they are termed as “grid connected mini/ microgrid’.
Village microgrids are also very popular in Asian and African countries, where villages are unable to afford expensive grid connected electricity.
In simple words, a mini/ microgrid is a small network of electricity users relying on a local source of power capable of functioning independently. With declining costs and increasing efficiencies s of renewable energy technologies, RE based micro and minigrids solutions are being perceived as a durable solution. The generator of a mini/ microgrid can be powered by RE sources such as solar, biomass, wind, small hydro and can have diesel-based generator as a backup. Hybrid systems using a combination of resources like solar-wind, solarbiomass, solar-hydro etc. can also be deployed.
The microgrid system consists of: ii Solar panels/ other RE source ii Inverter and batteries ii Low-voltage power distribution network ii LED lamps, compact fluorescent lamps, fan etc. for households Other components include charge controller, cables, circuit breakers, junction boxes etc. These components should confirm to the technical requirements and quality standards specified by the concerned government regulator or Ministry.
Types of Microgrids The microgrids can be classified into various types based on the function they perform:
ii Off-grid microgrids include microgrids on islands and other remote site which are not connected to a local utility network. ii Campus microgrids are fully connected with a local utility grid, but also maintain some services in isolation from the grid, for example during a power outage.

India is a huge county and a large portion of the Indian population still lives in darkness. The situation is even worse in villages, where people have to go to nearby towns for charging their mobile phone batteries. Thanks to solar lights and chargers, the condition has improved these days. The Indian rural market therefore offers a large potential for micro and minigrid projects which will help people meet at least their basic household needs.

based upon the mutually agreed tariff or the tariff as approved under the State’ policy, as may be applicable, and also adopt energy efficient measures to reduce the overall electricity consumption. The underlying principles of the policy are listed below: ii Mainstream RE mini/ micro grids for enhancing access to affordable energy services, and improving local economy ii Streamline project development procedures for ESCOs ii Provide operational frameworks to operate along with the Distribution Company (DISCOM) grid
Mini and micro grids will help in reducing dependency on fossil fuels, providing clean power to rural households, and meeting their aspirational needs. It not only reduces the cost of energy but also provides the stability and flexibility which gives user a variety of energy options to choose from. Microgrids help in a balanced usage of generation capacity of the grid basis the cost and energy structure. It also helps in grid resilience as it ensures that demand is met by timely supply from at least one of the resources if the other one is facing low generation or an outage. A microgrid is also digitally interactive and compatible with other grids and power networks. It is capable of interacting with nearby grids or the main grid where it can sell or buy power as and when required. Given its flexible nature, microgrids can easily be expandable and scalable. Hence, multiple generation and demand centers can be added to a microgrid. The villages can install solar pumps, solar lamps and fans, solar www.supersmartenergy.com
powered machinery (e.g. rice hulling machines). Using these products can help the villagers solve man of their everyday problems. The villagers can improve the efficiency of farming, children can read at night and women can do their household chores more conveniently.
“A customer would spend Rs 160 a month for his mobile charging and kerosene for lamps. We charge him Rs 100,” says Brian Shaad, co-founder of Mera Gao Power, a microgrid firm. ( Source: PluginIndia) Reliability, self-sustainability and flexibility are a microgrid’s USPs.
Future Plans The Ministry of New and Renewable Energy recently released a draft policy on micro and mini grids that will run on renewable energy sources like solar, wind energy, hydro and biomass plants. The policy aims to achieve a target of 500 MW of total capacity over the next five years. India is targeting to set up nearly 10,000 solar, wind and biomass-based power projects in five years in rural areas based around the concept of microgrids. The Ministry is also empanelling ESCOs as Rural Energy Service Providers (RESPs). Only approved mini grid RESPs will be eligible for any central financial assistance and other privileges. The state nodal agencies are responsible for keeping a record of all the mini and micro grids in their respective states. India is developing into a major growth market for solar microgrids, given the country’s increas-
ing demand for electrification. ABB which is a global leader in power and automation solutions sees India as a huge market for microgrid solutions. The company recently supplied microgrid solutions to Robben Island, situated 9 km off the coast of Cape Town in South Africa. Now the island can be powered by solar and battery, without any diesel generator for about nine months of the year.
The villagers also save money each month as they pay a lower amount of money for charging their phones, using lights, fans etc. when compared to the high costs of buying and using kerosene based products.
Mera Gao Power builds, owns, and operates micro grids in Uttar Pradesh, India serving off-grid villages with high quality, dependable lighting and mobile phone charging services. MGP’s unique model is
Challenges Funding remains the biggest challenge for the development of microgrids in India. People are asking for soft loans at concessional rates from the government. Though solar costs have declined rapidly in recent times with the prices of equipment falling by 80% since 2010, the high initial cost of solar equipment is a hurdle. Though the lifecycle costs of solar energy has become even cheaper than coal based power, the capital costs of installing solar based energy capacity is quite high. The upside is that there is no fuel costs since solar energy is free. The government needs to think of providing a special subsidy for this segment of the market to boost

While regulators have experience making rules for the main grid, doing the same for micro-grids poses a new set of questions. Tariffs should be such that it should allow the economic operation of the microgrid and at the same time be affordable for the end users who typically belong to the poorest segment of the society.
OMC Micropower Plant in Jangaon, UP, has made the impossible possible for the shopkeepers. Thanks to the Micropower plant the shopkeepers in Jangaon can now extend there business hours even after 6:00 pm. OMC is a power company that builds small-scale power plants with renewable sources where there is no reliable power grid. They sell power to both mobile networks and rural communities.

market uptake. Once the market develops, then it can grow without government support. Besides providing clean energy, solar based microgrids can also help meet multiple other government goals such as doubling of the farmers’ income by 2022. Kerosene subsidy is another major bottleneck in the expansion of off-grid solar markets. Though villagers have become more aware about the ill-effects of using kerosene, they continue to use kerosene at it is heavily subsidized by the Indian government. Villagers need to replace traditional kerosene lighting with off-grid solar power. The government has already removed subsidy on a number of fossil fuel products such as petrol and diesel and it has reduced the number of people who can avail of LPG subsidy by giving it to only the needy sections of the society. Like in the case of other fossil fuels, the government needs to slowly reduce the subsidy given to kerosene in a graded manner and its ultimate objective should be to completely eliminate the subsidy given to kerosene. Uncertainty around tariff payment and the absence of large commercial loads in villages are another major challenges. Clarity around tariffs is very important.
54 SmartEnergy Nov/ Dec 2017
The private sector is also reluctant to invest due to the government plan about extending the main power grid to areas which already have operating microgrids. It is important for the Indian government to specifically identify the areas/ villages where grid expansion will not take place. This would guide the micro-grid providers toward taking the right decision. Another issue which the micro grid market faces is the different forms of power. India’s main grid is based on alternating current (AC power). However, micro-grids are based on DC power. Lack of of standardization and clarity around operational regulations are major issues.
Funding Funding remains a constraint for all start-ups and new projects. The fixed cost of a mini/ micro grid consists of project development, generation plant, storage systems (batteries), inverters, distribution network, cost of availing debt including interest charges, fixed taxes and fees. Variable costs includes costs of fuel, oil, maintenance costs, copper losses of transformers, in storage devices, energy-related taxes and fees etc. A microgrid can cost nearly INR 60,000 to set up but the economics of this business is strong since the project cost is recovered within 3-4 years. It is a low-risk and sustainable business model, and hence attractive for the investors. The subscriber base is growing fast because people are soon realizing the economic and envi www.supersmartenergy.com
ronmental benefits of switching over to a solar microgrid. It is thus a win-win situation for all. Many financial institutions and philanthropic organizations are coming forward to raise funds for the construction of these microgrids in rural parts of India. The Ministry is also keen on working with States to develop an ecosystem to minimize the risk associated with such investments and mobilize capital. The Ministry is also encouraging financing for mini grids through institutions like NABARD and IREDA. The central subsidy would be channelled through NABARD/ IREDA to the Regional Rural, Scheduled or Cooperative banks. Thus a proper balance between policymakers, regulators, entrepreneurs, and industry players is imperative for the creation of a successful microgrid network.
Existing Projects in India Many small enterprises have been installing microgrid projects in the rural parts of India. Some of the popular ones are OMC Power (in UP), Mera Gao Power (UP), DESI Power (Bihar), Naturetech Infrastructure (UP and Bihar), Simpa Networks (Karnataka) Other notable micro grid projects in India are deployed in Baikampady Mangalore, Neelakantarayanagaddi village, Mendare village, and Kalkeri Sangeet Vidyalaya in Karnataka (by SELCO). Greenpeace has set up solar microgrid project in Dharnai village of Bihar. The Chief Minister’s residence in Bihar is also run on a solar microgrid. A report by the World Resources Institute and the Centre for Development Finance estimates the microgrid market at $2.1 billion annually. “Even if off-grid systems have 20% penetration, the installation base would be more than 7,000 MW,” says Anish De, Partner,
Infrastructure and Government Services, KPMG in India.
I n t e r n a t i o n al Experience The World Energy Outlook (WEO) estimated that 16% of the global population (nearly 1.2 billion people), did not have access to electricity last year. Almost 95% of them live in countries within sub- Saharan Africa and developing Asia. Analysts are very positive about the future of microgrid solutions globally. The microgrid market is forecasted to grow at 12% between 2016 and 2022 compounded annually, and reach $35 billion by 2025 at an astounding 21% CAGR. With improving technologies and reducing costs, renewable energy microgrids are now popular in all seven continents of the world. As per a report by Navigant Research, more than 1,840 active microgrid projects were identified spanning 135 countries across the seven continents. Asia-Pacific regions are particularly actively seeking the microgrid opportunity. According to GTM Research, the U.S. microgrid market, which accounts for 39% of the global microgrids market at present, is forecasted to reach 4.3 GW by 2020. More than 50% of the capacity will reside in U.S. military bases. Developing and implementing microgrid infrastructure could also help people at the time of
disasters. Schneider Electric and Engie are installing Southeast Asia’s largest hybrid microgrid project in Singapore. The microgrid is part of the existing REIDS program (Renewable Energy Integration Demonstrator in Singapore).
Conclusion India’s $11 billion rural electrification program, called Deen Dayal Upadhyaya Gram Jyoti Yojna, includes a target of delivering power to 18,452 villages by 2018. Of these, 14,204 can be served by grid extensions, and the remaining 3,449 need off-grid power. A growing population and increased demand for power could put pressure on the existing grid. The government of India has committed electrify all villages by 2018 and supply power to all households by 2019. The Ministry therefore plans to support micro grid program on a large scale. India should strive to develop the right business model for microgrid which would generate sufficient revenue to cover capital expenditures and maintenance costs while delivering a financial return. Microgrid could play a strategic role in the socio-economic development of people and communities. India can thus set an example for the rest of the world in achieving access to affordable energy through microgrid solutions

Head-to-Head: PERC or Mono Half-Cell
oth technically advanced and low cost seems like a dichotomous notion that rarely coexists in a singular form. However, things are about to change in solar as one of major technical advancements, half-cell modules, hits the market. Many Tier 1 manufacturers have already been heavily focused on developing half-cut designs. Industry experts expect that half-cut cells will continue to gain market share over the next 10 years. Take JinkoSolar as an example. Half-cell has been a technology that the company has been very excited about as the company finds that the performance gains by cutting the cells in half are well worth the extra manufacturing requirements. Compared to its conventional full-cell product, at JinkoSolar, half-cell products has a roughly 5-10 W output advantage based on different modules. The gains from half-cell technology are the most significant when applied to standard monocrystalline products. Given the performance and economical strengths of half-cell products on monocrystalline products, the conversation today when picking high performance modules is no longer about whether to pick monocrystalline or polycrystalline module, but about figuring out what dollar per kW/h to opt for.

.Could you shed some light on the difficulties a solar manufacturer has to overcome while doing business in India? Your suggestions in making India a global manufacturing hub for solar products? Today, Indian Solar Manufacturers have to thrive on Governments support in order to be in the busi-
ness. Let it be Solar Panel, Inverters or Small Solar Modular Products. Indian manufacturers have to match their prices with that of imported lower quality products. With no restrictions of any set of standards regulated on them, a necessary embargo on such products are essential by regulators or government. In order to make India as a global manufacturing hub, most importantly Proper financing mechanism has to been in Place where Banks should provide debt at a lower rate under clean energy fund, which is available in other
developed nations. Apart from finance - Skilled manpower, Adequate Infrastructure, Incentives based policy can help boosting solar manufacturing.
.Your assessment of the opportunities for solar retail products in India? How is a Pearl Energy making the most of these opportunities? Currently we see ocean of opportunities for Solar retail products. Special Programmes have been introduced by Government through MNRE such as Solar Water Pumps for farmers , Solar Power Packs with Lighting System for remotely located homes, Solar Micro Grids in remotest locations of India where Grid is not present. Under Corporate Social Responsibility various companies have adopted villages empowering them with Solar Energy, which has brought in awareness for Solar Power. PES manufactures and provides such solutions to the needful in remotest locations where Grid is not available. We have experienced large number of rising inquires from the end consumer in remote locations. We also help corporate companies execute solar solutions under CSR for diverse requirements, one of them Setting up Micro Grid for Hamlets. We actively participate in tenders to support Governments initiatives for Solar Energy.
.Share with our readers challenges in EPC project executed by Pearl Energy Solutions? What were the challenges and how did you overcome them? Indian Solar rooftop growth has seen an exponential rising curve, but the key challenges to EPC are still prevalent. Huge Resistance from DISCOMS for necessary permissions, Structural design and Engineering as every site has different orientations, Quality of Grid available, Logistics, Non availability of skilled man power are few
of them. Project timeliness and viability is adversely affected to huge extent due to above reasons. PES is trying to standardise operations, planning, designing, executions based on the learning’s from the previous projects. Also we have started training our sub contractors to achieve quality workmanship. We work on process out of our experiences and try to minimise the delays in projects caused due to any of the reasons.
.How to you tackle the challenge of small EPC players entering the market? What are the things a customer needs to know before choosing an EPC contractor for executing a project? As said Indian Solar industry has grown fourfold, so has the number of competitors. Whether it be small or big, everyone wants to be a part of the revolution. There are immense opportunities for every one available in market in various segments. So every player tries to offer something different sometimes lower prices, compromising on the quality is the challenge . The only way to tackle is to educate customers with complete transparency. Before choosing any EPC customer should focus on experience of EPC, Presence in market, Brand Value, Projects executed, Strength of the Company, Technological Collaborations.
.How do you look at the current status of the Rofotop sector in India? Are we on track of achieving the targeted 40GW from rooftop solar? Indian Rooftop has almost reached 2 GW capacity. The growth of this sector is realising its potential in coming years, 40 GW of Rooftop Solar Power by 2022 is a very ambitious target set by government . Although implementation of Solar Rooftops is happening at much lower pace then expected
with which it is unlikely that government could reach 40 GW target. Governemnt has to bring in some strong reforms in terms of net metering obligations on various Discoms for implementation.

62 SmartEnergy Nov/ Dec 2017
The three days of exciting proceedings open on December 5, 2017 at the Bombay Exhibition Centre (BEC). Over 100 industry experts from Indian and global solar and energy storage industries and policymakers will share their insights. Over 500 delegates are expected to participate in
the conference. This year’s exhibition is certified by the US Department of Commerce and has US and German pavilions besides an exclusive pavilion for Electrical Energy Storage. Approx. 260 domestic and foreign exhibitors are showcasing their latest products and solutions and over 12,000 national and international visitors are expected to visit and benefit from the event. Conference Highlights Global installed PV capacity grew sevenfold between 2010 and 2016, from 40 GW to more than 300 GW. In 2017, an additional 100 GW capacity was added globally. In India the installed utility scale solar capacity jumped from a mere .01 GW in 2010 to more than 13 GW by June 2017. The German based Fraunhofer Institute forecasted in 2015 that the global installed capacity would scale to 668GW by 2020.
This rapid expansion would support a thriving solar industry and would also open the doors to further opportunities. According to GTM Research, the global O&M and Asset Management in 2016 reached 182 GW recording a staggering 54% growth over the previous year. Newer technologies like the Floating PV that helps reduce the pressure on land and agro PV technologies that enhance the utility of land are receiving increased attention. The global attention the inauguration of China’s largest 40 MW floating solar plant received this year is a case in point. With India’s total installed capacity rapidly growing, business opportunities in O&M and asset management segments could follow global trends. The recent commissioning of a 100 KW floating solar plant in Kerala, owned by India's largest energy conglomer-

Curtain Raiser into one of the top three global PV markets. International financing institutions like The World Bank, Asian Development Bank, KfW, European Development Bank and others are infusing funds to help accelerate the rooftop market. Electrical Energy Storage, that hardly drew attention until recently is gaining momentum. A 28 MWHr battery storage system integrated with a 20 MW plant is coming up in the Andaman & Nicobar Island. The recent Government announcement to go 100% electric vehicles by 2030 has triggered unprecedented excitement and the dawn of a burgeoning storage market is very imminent. With winning solar power tariff creating record lows in every successive bid, there is growing concern that quality may be compromised which in turn could have serious implications. The recent introduction of GST has thrown up challenges and the debate on local vs. imported continues to be contentious. The conference topics have been structured on the background of the evolving Indian PV market. With wind sector continuing to contribute significantly to India’s RE capacity and with increased interest in other RE systems, solar cannot be seen in isolation. For this reason this year’s Panel Discussion will focus on “The Future of Renewable Energy in India” The conference has standalone sessions arranged by Intersolar and sessions organized in partnership with reputed institutions. The Solar Energy Research Institute of Singapore (SERIS) is organizing the session on Floating Solar and PV Quality, the German Development Co-operation (giz) will organize the session on Residential Rooftop Systems – Design and Quality, the German Engineering Federation (VDMA) will conduct the Manufacturing session while the Alliance for Rural Energy (ARE) is holding

Rising Temperature Adversely Affecting The Performance of Solar Modules The mitigation of environmental effects on clean-energy technology is an area of increasing interest. Photovoltaic (PV) modules have been widely used in small and large-scale applications for many years. However, there performance is affected in environments that suffer from dust, airborne particles, humidity and high ambient temperatures. Prodyut Bagchi, Senior Vice President, Angelique International Limited expresses his views on the effect of climatic conditions on PV module performance, in particular, the effect of rising temperature.
.With rising temperatures, do you see generation from your installations coming down? India has an average annual temperature that ranges from 25°C to 27.5 °C because of its location between the tropic of cancer and the equator, There are average 300 sunny days in country and this implies that India has a very high potential of generating solar energy as availability of solar radiation in various parts of the country is quite good. Solar cell performance decreases with increasing temperature, fundamentally owing to increased internal carrier recombination rates, caused by increased carrier concentrations. The operating temperature plays a key role in the photovoltaic conversion process. Both the electrical efficiency and the power output of a photovoltaic (PV) module depend linearly on the operating temperature. Rising temperatures definitely bring generation down.
.Can you provide comparative figures about how much power the company's project/s would generate in the summer months vis-a-vis average generation? (in KwH terms) Solar cells perform better in cold rather than in hot climate and as things stand, panels are rated at 25˚C which can be significantly different from the real outdoor situation. For each degree rise in temperature above 25˚C the
panel output decays by about 0.25% for amorphous cells and about 0.4-0.5% for crystalline cells. Thus, in hot summer days panel temperature can easily reach 70˚C or more. Thus, 100W panel will produce only 75W in May/June in most parts of India where temperatures reach 45˚C and beyond in summer and electricity demand is high.
.In your estimate, how would this phenomenon (temperature effect on modules) might impact the overall installed capacity of around 13 GW across the country? So like I said in my previous answer a 100 W panel may only produce 75 W in May June so one can apply the Maths
.Has there been any recent technological breakthroughs to counter this issue? Solar panels are tested under laboratory conditions, called STC (Standard Test Conditions): at an Irradiance (light) level of 1000W/ m2 with a temperature of 25˚C. But in the real world these conditions are constantly changing so the panel output is different from the lab conditions. So, another specifications are reported, called NOCT (Nominal Operating Cell Temperature). It is the temperature reached by open circuit cells in a module under the following conditions:
solar panel at 800W/m2; Air temperature of 20ºC; Wind speed at 1m/s; and the panel is mounted with an open back (air can circulate behind panel). Most good quality panels available today in India have NOCT values of 47±2˚C. Lower the NOCT the better it is expected to perform in hotter climates. Also, there are several ways to minimize the negative effects of high temperatures: ii Install panels a few inches above the roof to allow convective air flow to cool the panels down. ii Ensure that panels are constructed with light-colored materials, to reduce heat absorption. ii Move components like inverters and combiners into the shaded area behind the array
ii Irradiance (light) falling on the

BM India launched the 11th edition of the Renewable Energy India (REI) Expo, the three-day (20th to 22nd September 2017) show at the India Expo Center, Greater Noida. The expo was inaugurated by key dignitaries, Shri Upendra Tripathy, IAS, Interim Director General, International Solar Alliance (ISA); Mr. Justin Wu, Head of APAC, Bloomberg New Energy Finance, Hong Kong; Ms. Henriette Faergemann, Counsellor - Environment, Energy, Climate Change, Delegation of the European Union to India; Mr. Hans-Josef Fell, President of the Energy Watch Group (EWG ) & Former Member of German Parliament; Mr. Naoki Tomotake, Director General International Affairs, NEDO, Japan; Mr. Rene Van Berkel, UNIDO Representative to India; Shri Anand Kumar, IAS, Secretary, Ministry of New and Renewable Energy, Government of India; Mr. Yogesh Mudras, Managing Director, UBM India; Mr. Michael Duck, Senior Vice President, UBM Asia and Mr. Rajneesh Khattar, Group Director, UBM India amidst an august industry gathering. The show discussed global best practices and sought solutions to some of the most pressing challenges in the power and energy sector, bringing in internationally renowned exhibitors, consultants, business experts and key government officials under one grand platform. At the opening ceremony of the Renewable Energy India (REI) Expo, Anand Kumar, the Secretary of India's Ministry of New and Renewable Energy (MNRE), stated, "Under Prime

Minister Modi, we up-scaled our total renewable energy target to 175 GW by 2022. With advancements in technology, and with price of solar and wind reducing, we are not only sure but confident that we will not only achieve the target, but exceed it. In recent consultations, the MNRE has begun to take more seriously the potential of India's offshore wind and hydropower capacities, and hinted that these technologies will be brought under the renewable energy target." Kumar also spoke of India's 'silent revolution', which will see the country rapidly scale up its electricity generation capacity and consumption. "The key challenge is: how should we enable higher energy consumption in India, at a cost people are willing to pay?" he asked, adding: "And not only willing to pay, but able to pay?" The path of least resistance, he affirmed, is the one with the lowest carbon intensity. "India has limited fossil fuels. We depend on imports for petroleum. If we have to support and meet the demand of 1.25 billion people, then renewables are the only way." Kumar also turned his attention to manufacturing, particularly solar manufacturing where, he said, India's capabilities are "modest" at best. He concluded. "We should set up manufacturing bases for batteries in India. Once we overcome the obstacle of storage, then the ideal of 24-hour free energy for the people can be realized." The 11th edition of REI saw participation from countries high on the Renewable Energy Attractiveness Index such as India, Japan,Germany, France, Poland, USA, Korea, China and Taiwan amongst others.
