Words from the


“In India, we have started the world's largest renewable energy expansion program. We will generate 175 GW of electricity from renewable sources of energy by 2022, of which 100 GW will be from solar power. We have already achieved 20 GW installed solar power,” Honorable PM Modi said here at the International Solar Alliance (ISA) Summit that was co-hosted by French President Emmanuel Macron. But even as the PM boosted about India’s achievements in solar, the ground realities have been changing fast from celebrations to concern and caution. Concerns about higher taxes and import duties on solar panels making the developers reluctant to bid for new projects. Amidst this gloom there is hope from the states, which have been focusing and relentlessly trying to add solar capacity. Telangana, Karnataka, AP, Rajasthan and Tamil Nadu are the top 5 states that are carrying the mantle successfully. In doing so, states like Karnatak have gone large by successfully commissioning 600MW of the 2000 MW Solar Park located at Pavagada Taluka in Tumkur district. Pavagada mega solar park is a phenomenal project and the unique thing about this project is that not a single acre has been acquired from the farmers; instead the land has been procured through signing of long-term leases with landholders. Another state that is making its presence felt is the state of Uttar Pradesh. Uttar Pradesh has set the target of 10,700 MW for solar power, including 4,300 MW from rooftop solar projects, by 2022. The writer of the cover story in this edition of Smart Energy Magazine tracks the overall performance of solar sector in 2017 and the efforts and support from the key states in achieving overall target. This edition also carries an interesting article on muncipal bonds as a source of finance for rooftop solar projects. Also, you get to read about Exicom Power Solutions, a company with over 20 years of experience in designing, engineering and manufacturing of complete range of power solutions for ever changing telecom requirement, Industrial, IT and other markets.

We Need A Solar Revolution Not Only in India But in The World: PM Narendra Modi at Founding Conference of ISA


ith French President Emmanuel Macron by his side at the founding conference of the India-initiated International Solar Alliance (ISA), Prime Minister Narendra Modi presented a 10-point action plan to promote the use of solar energy. Speaking at the plenary session of the conference, Modi said there should be a full ecosystem for availability and development of technology, economic resources, development of storage technology, mass manufacturing and innovation. "We all have to think about the road ahead and I have a 10-point action plan that I would like to share with you. "First of all, we should ensure cheap and easy availability of solar technology. The solar ratio in the energy mix should be increased and innovation should be encouraged so that solutions for our various needs can be provided," he said. The Prime Minister called for concessional financing at lower risk for solar projects. He said regulatory aspects and standards should be developed to find solutions fast. "Consultancy support should be developed for bankable solar

projects in developing nations. "We should work for increased participation and inclusiveness. We should build a comprehensive network of centres of excellence keeping local circumstances and factors in mind. We should look at our solar energy policy development in totality so that this can play a role in meeting the SDGs (Sustainable Development Goals of the UN)." Modi also called for a strong and professional ISA Secretariat located in Gurugram. Launched by Modi and then French

President Francois Hollande in 2015, the ISA was conceived as a coalition of solar resource-rich countries to address their special energy needs and provide a platform to collaborate on dealing with the identified gaps through a common, agreed approach. It is open to all 121 prospective member countries falling between the Tropics of Cancer and Capricorn. "Of the 121 prospective nations, 61 have joined the alliance, 32 have also ratified the framework agreement. But in this alliance our biggest partner is the sun god which spreads light outside and gives strength to our resolve," Modi said. He, along with Macron, who was on a four-day visit to India, cochaired the conference. "Even before life first opened its eyes on earth, for ages the sun has been enlightening and enriching people. From Japan to Peru, be it Greece or Rome, Egypt, Incas and the ancient Mayan culture, every civilisation has glorified and given importance to the sun. "However, in India, from thou-

sands of years ago, the central place that has been given to the sun is unparalleled. From thousands of years ago, the Vedas in India have seen the sun as the soul of the world. "In India, the sun has always been seen as the nurturer of life. Today, when we are trying to find paths to fight challenges like climate change, we have to look at this ancient idea." Stating that a green future will depend on "what we can all do together", Modi said in India work had started on the world`s largest new energy initiative. "By 2022, we will generate 175 GW of renewable energy of which 100 GW will be solar power," he said.

"Of this, we have already met a target of 20 GW of installed solar power." He said the aim of the Atal Jyoti Yojana was to install street lights based on solar energy in areas faced with the problem of inadequate electricity. "The Solar Study Lamp Scheme has benefitted seven million school going children. "We need a solar revolution not only in India but in the world," the Prime Minister asserted. He said India had contributed $62 million to the ISA corpus fund and for the establishment of the ISA secretariat. "I am happy to announce that

India will provide 500 training slots per year for ISA member states." Modi said 13 solar projects by India across the world worth $143 million have been completed or are in the process of being executed. India, he said, would give $1.4 billion in aid to 15 other developing nations for 27 more solar projects. "We have set up a project preparation facility consultancy support to partner countries in designing bankable projects. "I am happy to announce that to fill the solar gap, India will launch a Solar Technology Mission. Its focus will be global and our governmental, technical and academic institutions will lead in R&D efforts in the solar sector." 

News & Views Pavagada Solar Park Inaugurated Chief Minister Siddaramaiah inaugurated the 2,000 mega watt (MW) solar power park at Pavagada in Karnataka's Tumakuru district. "Karnataka has emerged as the third largest producer of renewable energy in the country. We have set a goal to source at least 20 per cent of people's power requirements from renewable projects," Siddaramaiah said during the inauguration. In the future, Karnataka aims to be an energy surplus state, he said. Built on 13,000 acres across five villages, the solar power park is being set up with an investment of Rs 16,500 crore. "The solar park has farmers from the Pavagada region as partners and beneficiaries, leasing out their lands for the park," said the state's Energy Minister D.K.Shivakumar. The 2,000 MW solar park, also called the Shakti Sthala, is situated at Pavagada in Tumakuru district of Karnataka. The massive park has been built over 13,000 acres across five villages with an investment of Rs 16,500 crore. According to a press statement, "The project has been executed within a record time of two years, with zero land acquisition. Moreover, the farmers who have leased out their land are reaping greater benefits with Rs 21,000

per acre being offered as rental, an amount which has the scope to grow by 5% every two years." One of the most drought-prone regions in the state, Pavagada has witnessed large scale migration over the last decade. With the solar park, the government aims to help local farmers and also create a source of unlimited clean energy. "Pavagada, in Tumkur district, is one of the most arid regions of our state. Over the last five decades, due to extreme weather conditions and low possibilities of economic growth, more than 10,000 people had migrated annually from Pavagada. To solve this problem, we are building the world's largest Solar Power Park of 2000 MW in Pavagada taluk on mission mode. This ambitious project, spanning five villages, looks at farmers as the key partners, as also beneficiaries. Shakti Sthala is creating new job opportunities and economic growth leading to the prosperity of the people of Pavagada," DK Shivakumar, state energy minister, said. Under the 'Karnataka Solar Policy 2014-2021' launched in May

News & Views ISMA to a file a fresh Petition with Recent Period of Investigation Indian Solar Manufacturers’ Association (ISMA) announced that it has withdrawn its petition for antidumping duty on solar cells and modules, covering the period of investigation till June 2017. The association added it will soon file a fresh petition with a more relevant and a recent period of investigation. “The import trends since then (filing of the petition) have made the period of investigation irrelevant. Despite an ongoing investigation, the exports from China, Taiwan and Malaysia of cells and modules increased by 33 to 45 %, during the period from July 2017 to Dec 2017,” ISMA said in its statement. The association added the massive increase in volumes was enabled by a significant price reduction to dump more material in India. The prices in the same period fell by about 25%. “This has resulted in an enhanced injury to the Domestic Industry which would not have been fairly addressed by the outcome of an investigation covering the period upto June 2017,” ISMA added. ISMA remains confident it will soon

approach the concerned authorities with a fresh petition “The objective is only to get a fair and just redressal of our grievance,” it said in its statement. The association in its petition said that around 80 per cent of the solar cell and modules market had been cornered by imports. The petition filed for investigation till June 2017, was the association’s third such attempt to bar solar imports from flooding the Indian market. The first case was filed in 2012 against the US, European Union, China, Malaysia and Taiwan. The case ran for two years saw solar cell makers, allied electronics industry and even glass makers asking for protection against the import of solar panels. While DGAD finalised duties from $0.48 per unit to $0.81 per unit on solar cells imported from the above mentioned countries, the ministry of finance did not impose the same and let the duty lapse in May 2016. In 2014, the makers filed a complaint with Directorate General of AntiDumping (DGAD) under the ministry of commerce and Directorate General of Safeguards (DGS) under the ministry of finance 

Government invites tenders for 3,000MW solar projects In what turns out to be a surge in solar tenders, the central government has invited bids for 3,000 MW of solar power projects connected to the interstate transmission system. With this, the capacity of solar tenders invited by the central government in the first two months of 2018 stands at more than 5,000 MW (275 MW in Uttar Pradesh, 200 MW in Karnataka and 2,000 MW inter-state in January). The Solar Energy Corporation of India (SECI) would sign 25-year power purchase agreements (PPAs) with the winning bidders and sell the power to electricity distribution utilities (discoms). The ceiling tariff for the latest tender has been set at Rs 2.93 per unit. The

18 SmartEnergy March/ April 2018

reverse auctions would be conducted for 12 projects of 250 MW each. The capacity additions would help the country achieve the target of 100 gigawatt (GW) of installed solar energy capacity by 2022. Power and renewable energy minister RK Singh had in November announced the break-up of his action plan for completing 80 GW of solar auctions by FY20, leaving a margin of two years to complete the projects by 2022. According to that agenda, another 8 GW of solar tenders can be expected by March 2018.

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

DEIF’s Automatic Sustainable Controller

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

22 SmartEnergy March/ April 2018

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@ We look forward to working with you.

Haliade-X 12 MW, the largest offshore wind turbine in the world to date


ntroducing the Haliade-X 12 MW, the largest offshore wind turbine in the world to date, featuring a 12 MW capacity (the world’s first), 220-meter rotor, a 107-meter blade designed by LM Wind Power, and digital capabilities. In addition to being the biggest offshore wind turbine, the Haliade-X will also be the most efficient of wind turbines in the ocean. Best of all, it’s capable of transforming more wind into power than any other offshore wind turbine today. The Haliade-X 12 MW also features a 63% capacity factor*- five to seven points above industry standard. Each incremental point in capacity factor represents around $7 million in revenue for customers over the life of a windfarm. POWER MEETS EFFICIENCY The offshore wind turbine design of the Haliade-X is what makes it unique. The combination of a bigger rotor, longer blades and higher capacity factor makes Haliade-X less sensitive to wind speed variations, increasing predictability and the ability to generate more power at low wind speeds. The Haliade-X can capture more Annual Energy Production (AEP) than any other offshore wind turbine even at low wind conditions. This 12 MW ocean wind turbine can also generate 67 GWh annually, which is 45% more AEP than the most powerful machines on the market today, and twice as much as the Haliade 150-6MW. One Haliade-X 12 MW can generate enough clean power to supply European 16,000 households according to wind conditions on a typical German North Sea site. Based on a 750 MW windfarm and an estimated AEP, the Haliade-X 12 MW could produce enough power for up to 1 million households.

BOTTOM LINE IMPACT Haliade-X 12 MW doesn’t just set a new benchmark for the size of wind turbines at sea. It can also bring higher profitability to customers. The Haliade-X 12 MW provides significant savings across offshore wind turbine manufacturing, installation cycle times, service and repairs, through its simplified process and intelligent components. While the Haliade-X 12 MW sea turbine is well-suited for high-to-medium wind speed environments, its larger capacity can produce energy even at lower wind speeds, increasing profits and dramatically lowering the levelized cost of energy. With fewer machines and offshore wind turbine foundations to install, in addition to reduced cycle times and simplified operation, the Haliade-X 12 MW generates robust savings on overall project cost (CAPEX Balance of Plant**) over the life of a windfarm, saving an average of $26 million per turbine per 100 MW when compared to Haliade 150-6MW. Digital tools (based on GE’s Predix platform) are currently being developed exclusively for the offshore environment with an operations approach, that will

help customers perform remote diagnostics, improve time management (less time at sea) and optimize operations. INVESTING IN THE FUTURE The offshore wind market is booming and is expected to grow significantly over the next two decades; from today’s 14 GW install capacity to 100 GW+ by 2030. Recognizing this need, GE is leading the field of offshore wind turbine manufacturers by investing $400 million over the next three to five years in development and deployment of the Haliade-X. This investment will take place over the next two to five years and includes a $57 (€46) million investments in Saint-Nazaire to adapt the site for Haliade-X nacelle assembly. Saint Nazaire’s knowhow will play a crucial and leading role in the development of this innovative project, with offshore wind turbine construction at higher capacities. An additional $93 (€75) million in Cherbourg for tooling, blade molds, assembly line and blade development. This project will create 550 direct jobs in Cherbourg over the course of the next 3 years (around 100 in 2018) 

We are pioneers in Energy Storage Projects in Distributed Form (in Telecom) and have done very well on grid-scale solutions as well. We have successfully deployed

32 SmartEnergy March/ April 2018

over 600 MWh of Battery Energy Storage System out of which 450 MWh Lithium-ion Battery Solutions at Telecom Tower Sites have been progressively deployed for a period of 5 years. They have been performing well and above satisfaction levels of our esteemed telecom customers. Our batteries are making their telecom network more stable and greener by reducing DG run hours while ensuring demand supply management and lesser carbon footprints. We have also executed three gridscale high voltage projects of Battery Energy Storage System (BESS) for PGCIL and CEL that were used for frequency regulation, voltage regulation and energy storage application respectively. The suc

cessful running of these projects over years will provide Policy / Regulatory advocacy for deployment of such technologies for grid stability and improve power quality in our country. The team has worked tirelessly to overcome many technical challenges while doing PGCIL Project in Puducherry that is a coastal region to create exemplary projects to accelerate India’s transition to a clean energy future. Exicom has bagged majority of Govt. based tender opportunities and has always stood at a dominant position in this field.


.With the current government’s emphasis on electrical vehicles (EVs), how do you look at the charging and storage market for EVs in India? With Government of India’s push, EVs have really taken a quantum leap compared to what it was a year back. There are many nodal agencies like NTPC, BHEL, IOCL, PGCIL etc. which are working to build charging networks and supporting infrastructure in the country to make EV mission a success and ensure electric vehicles have a smooth ride on Indian roads. Companies like EESL are doing mass procurement of over 10000 EV’s and doing the deployment all over India, As per the information on public network EESL is going to deploy over 4000 charging stations shortly. With the momentum enthused by EESL and other nodal agencies, many private companies and Government PSUs are planning to deploy either EVs or EVSEs as part of their plan. Many State Governments have already started procuring and deploying the electric buses/cars and charging infrastructure to support them. We do see lot of progress in the EV industry and foresee a good growth in the coming years as well.


.Share what are the challenges and opportunities

in developing reliable EV infrastructure? Also, share with our readers your experience of installing EV charging stations at UN office and NITI Aayog? Making electric mobility mainstream is one of the biggest challenges and opportunities we face. If electrification of transportation is successful, it will bring many benefits in the form of better air quality, lower operating costs for vehicles and environmental savings - not to mention better vehicle performance. E-mobility also represents an important opportunity to overhaul our energy infrastructure and make necessary investments in renewables and new grid technologies. We feel that the government has played a significant role in setting standards and regulations for charging infrastructure and providing incentives for electric vehicles. The government should also encourage research and development, localization, and training to improve energy access to developing charging infrastructure. Policy interventions, including mandates and incentives that promote investments in developing local EV targets, will also be needed sooner than later. We need to work very quickly on building up infrastructure in power both on quality and reach side. There is also a need to scale up the rollout target by focusing on shorter and pre-defined routes as well as by providing charging stations at multiple locations which would further enable the cost of storage to drop. We had a very good experience of installing EV Charging stations at UN office and NITI Aayog. These chargers are being used to charge the Government cars. The support from various administrative and electrical bodies both within UN Office & Niti Aayog has been exemplary.

Rooftop Solar

Using Municipal Bonds to Finance Rooftop Solar projects


here is both an opportunity and challenges of using municipal corporation for the acceleration of rooftop solar. Therefore, if municipalities are to play a role in the necessary acceleration of rooftop solar in India, they will need to look for new sources of finance and business models to spur the required development. This will also require building partnerships with local solar developers and other stakeholders in the domestic and even international financial markets.

accounts for approximately 84% of currently existing rooftop solar systems in India and is mainly driven by commercial and industrial operators.

There are two business models to deploy rooftop solar in India.

›The second model is the OPEX model or the third party financing model in which a renewable energy service company (RESCO) provides all the necessary capital and is responsible for installing, operating, and maintaining the rooftop solar system in exchange for a fixed tariff Power Purchasing Agreement (PPA) with a customer, or multiple customers. This model is also referred as third-party financing model.

›The first one is the CAPEX model in which the consumer fully owns, finances and consumes the energy generated by the PV system. Consumers in the CAPEX model are fully responsible for all capital expenditures, and bear all risks of operations, management, and maintenance. The CAPEX model

As CAPEX model is a self-funding model for the rooftop solar projects as far as the end consumer is concerned, it does not require much financing support from external entities. On the other hand, the third party financing model requires significant debt investment from the capi-

36 SmartEnergy March/ April 2018

tal market. Hence, the municipal corporation can collaborate with the rooftop solar developers to facilitate the access of the debt capital from the capital markets under the OPEX model route. A research article published by the Climate Policy Initiative (CPI) proposes the OPEX model as one of the promising solutions to address several barriers to scaling rooftop solar. According to studies conducted by CPI, the third party financing model is expected to dominate the rooftop solar market, given its benefits for consumers of no upfront and installation cost and the operation and management services being carried out by local developers. Globally, the third-party financing model has been a significant driver of growth in the rooftop solar sector. However, the third party financing model has not picked up in India at the rates expected due to the lack of avail-


ability of debt capital at competitive cost, which affects the ability for companies advancing this business model to scale. Thus, to achieve further scale for the OPEX model for rooftop solar in India, alternative methods of financing should be considered.

Overview of Solar Municipal Bond Model:

all activities from design to operation are taken care by a private developer. In the proposed model, however, CPI recommendes that municipalities should raise debt capital to finance rooftop solar development. The transaction structure is similar to the Morris County model successfully used in the USA for financing the rooftop solar but limited to the public

places only. The proposed SMB model advocates its implementation beyond public buildings.

Rationale for municipal bonds for rooftop solar projects: Before discussing the transaction


The CPI study propose an alternate approach where municipal corporations can play the role of finance aggregators for rooftop solar projects deployed under the OPEX route. The proposed model called Solar Municipal Bond (SMB) model advocates a bottom-up approach to facilitate financing for rooftop solar projects and complements the existing government efforts to achieve the 40 GW national targets. The SMB model suggests using municipal financing for rooftop solar projects. It is based on a publicprivate-partnership (PPP) investment approach for rooftop solar projects at city level where municipalities would issue bonds and then transfer the proceeds to private solar rooftop developers through special purpose vehicles (SPVs). This model differs slightly from a conventional designbuild- finance-operate (DBFO) model. In a typical DBFO investment model,

structure of the solar municipal bond model in more detail, let us take in to account the rationale of using municipal bonds as financing mechanism for the rooftop solar: ii Build-in Incentives for Municipalities under Solar City Program Municipalities have target-based responsibilities to increase renewable energy deployment under the Solar City Program, so they have a built-in incentive to increase rooftop solar in their jurisdiction. However, the targets set under the program are quite moderate and municipal corporations can be given additional responsibilities to increase these targets as per their true potential. ii Municipalities are in a better position to raise capital by issuing bonds The main advantage for the proposed public-debt based financing for rooftop solar under the OPEX model is that compared to private developers; municipal governments are in a better position to raise capital by issuing bonds. The key reason behind this is that Municipal Corporations have relatively larger balance sheets as compared to that of a rooftop solar developer, which provides the feasible financial strength and

capital base to raise bonds from the capital markets. ii High credit worthiness One important reason why municipalities are in a better position to raise debt-based finance than project developers is their credit ratings relative to that of rooftop solar project developers. More than half of the rated municipalities - 94 in total- are investment grade (i.e. BBB- or above); whereas almost all rooftop developers are below investment grade. A high credit worthiness is essential for successful listing of a bond as it not only helps in reducing the cost of debt servicing but also attracts long-term institutional investors. ii Easier access guarantees:



Being government-backed entities, municipal corporations can leverage upon the strength of the state or central government to secure guarantees on bonds. This helps in raising the credit rating of the bonds. For private project developers, it is quite difficult to access such guarantees from the government institutions. ii Security for investors In addition to the project revenues which are used to service the bond payments, municipal corporations

38 SmartEnergy March/ April 2018

PPA Payments

Consumers, Off-takers

have various other streams of revenues such as property taxes, service taxes etc. which can provide security for investors in case project revenues are not sufficient to service the bond payments. Private solar developers rarely have revenues other than that from solar energy generation. ii Enhanced Feasibility One of the key issues that a private rooftop solar developer faces in raising the debt capital is the small size of the projects, which increase transaction costs. Given municipalities’ relatively good proximity with the consumers, the municipal corporation can quickly facilitate rooftop solar project aggregation. If rooftop solar developers would like to access the debt capital through municipal bonds, multiple developers would have to aggregate their projects at city level which would ensure the aggregation of the projects and make the issuance of the bond more feasible. This process will also help to reduce the transaction costs of raising the debt capital.

Incentives for municipal corporations Municipal bond issuance can expedite governance reforms. A municipal bond issue would mean not only a plethora of challenges


but also offer the local body a number of opportunities. Most importantly, a successful bond issue warrants financial discipline and accountability of the issuer. Past experiences have proved that efficiency of project management systems, procedures to reduce time delays and cost overruns, and a healthy revenue system are essential for constant engagement with capital markets. A rooftop solar project in this respect could be a less risky project than alternative projects to be funded through bonds as the revenue streams of a rooftop solar project are largely assured due to PPAs and would prepare municipalities for larger issues in the future.

Transaction Structure of the Proposed Municipal Bond Model The proposed solar municipal bond model for rooftop solar combines public debt-based finance with an existing OPEX model.

Under this mechanism, a public entity would issue a bond at low cost- long tenor and transfers the bond proceed to a private developer. This model is quite similar to bond-PPA model called Morris County Model, named after Morris County in New Jersey, U.S., which developed the model to finance solar power installations on public facilities in 2011. However, in the proposed bond model for India, CPI proposes going one step further from the U.S. based Morris county model. In Morris County model, the municipal corporations raise bonds to facilitate the financing of only those solar projects, which are installed for municipal corporation consumption. In the CPI model, the fund raised through a municipal bond would be used to finance as many rooftop solar projects as possible including residential, commercial, and industrial customers.

The model combines many of the benefits of self-ownership and third-party ownership from the perspective of local government as consumer. Like self-ownership, the model allows local government to leverage low-cost public debt. Like a third-party financing model, the proposed model enables the developer to benefit through savings passed on from tax incentives i.e. the accelerated depreciation benefit. In addition, the local government and the other consumers receive fixed electricity costs for a long-term contract and have no operating and maintenance responsibilities for the solar equipment. Figure 1 shows the transaction structure of the municipal solar bond model that is based on public-debt and OPEX model of project deployment. A public entity, in this case a special purpose vehi-


Rooftop Solar cle (SPV) which is 100% owned by a municipality, issues a revenue bond which would be ring fenced with the project cash flows. We refer to this SPV as Master SPV or the corporate municipal entity (CME).The bond can be raised by the municipal corporation directly as well. The main reason of raising the bond via SPV is to de-link the financial risk of the project from the municipal corporations’ financial books. However, we have assumed that the CME or the municipal corporation, whoever is raising the municipal bond, meets the required eligibility criteria laid by SEBI (SEBI 2015). The CME then issues a request for proposal (RFP) seeking solar developer(s) to build, operate and own solar rooftop projects or a portfolio of projects on municipal buildings and other consumer segments. The CME floats the bond to finance/refinance the development cost of solar PV projects. The CME then enters into a capital lease agreement with the project SPVs owned by project developers. The project SPVs then sign a PPA with consumers to sell the electricity from PV systems.

Limitations of the Solar Municipal Bond structure ii Size of municipal bonds As per the SEBI’s guidelines, a bond should have a minimum issuance size of INR 1 billion if the issuance is via public placement route. Municipal Corporations can also go for a private placement route to raise the bond as there is no such restrictions. However, if we want to optimize the transaction cost, the issuer should ideally raise at least INR 1 billion for private placement and INR 1.5 billion for public placement. Debt-based capital of this size would allow municipalities and solar rooftop developers to build rooftop solar systems of large-scale, and achieve low capital costs by pooling in individual small-scale projects. ii The model is more suitable for

non-residential consumers The credit rating of the bond is one of the key criteria to ensure its successful subscription. In addition to the credit rating of the SPV, which depends partially on the rating of the respective municipality, the off-taker risk would be of utmost important. In the case of rooftop solar installed under the Opex route, enforcement of PPA contracts is a major concern for the project developers. This enforcement becomes relatively difficult when the off-taker is a residential consumer. On the other hand, off-taker risks of municipal, commercial, and industrial consumers are relatively lower. Also, most of the existing rooftop solar projects under OPEX models in India involve commercial and industrial customers. Hence, for initial success of the SMB model, it is recommended disbursing the capital from the bond proceeds for the projects in the non-residential consumer class. Hence, the solar municipal bond model will remain most suitable for nonresidential customers because of low off-taker risk until a solution is found to reduce residential offtaker risk.

ii Short-term solutions for refinancing projects through the municipal bond It should be noted that the origination of initial debt would be through a conventional bank as bonds are not suitable when portfolios of projects have not reached to a certain scale, as is the current case in India for rooftop solar. Once the projects get stabilized and start generating regular revenues, the initial debt would be refinanced through the municipal bond. It is assumed that a bank would agree to originate the short-term loan because of: a) the larger size of the projects achieved through aggregation of all the projects at the municipal corporation level; b) the assurance from the municipal corporation that the initial short-term loan would be paid or refinanced through a Municipal bond within a year or two. Another way to reach the required stability in project portfolios before the municipal bonds can be raised would be to create a warehouse line of credit. This

warehouse would take care of the required aggregation of the creditworthy rooftop solar projects and also provide the initial line of credit over a period not exceeding 24 months. Once the required aggregation and the stability in terms of project cash flows is achieved, the refinancing of the warehouse line of credit would be done by issuing asset backed municipal bonds. The refinancing should reduce the loan costs and free up capital from the warehouse line of credit to finance additional projects.

Expected benefits of the solar municipal bond ii Reduced levelized cost of electricity from rooftop solar The solar municipal bond structure is expected to offer better debt terms than commercial alternatives, which are passed on to electricity consumers. In this model, the project developers make capital lease payments that fully cover the bond service payments. These lease payments would be lower than the payments on commercial loan that a solar developer would otherwise have borrowed. The lower cost is expected due to the better credit rating of the municipalities, overcollateralization of the bond, and certain upfront payment towards the capital lease. The tenor of the lease is also expected to be longer compared to that of the commercial loan due to more flexibility available in a capital lease mechanism. Hence, the cost savings due to low-cost, long-term lease capital would enable the project developer to offer an attractive PPA price to its consumers. Table 2 shows the expected impact of cost of financing using municipal bonds on the cost of rooftop solar power. As there are little empirical data about the yield curves of municipal bonds in India, it is difficult to estimate the probable costs of municipal solar bonds. Thus, here the cost of debt of the recent green bonds raised by Indian entities is used as

a proxy to estimate the benefits of the proposed municipal bond.

of investors into the rooftop solar sector

A tax-free bond for a tenor of 12 years can reduce the solar power cost by 8.38%, and, if tenor can be increased to 15 years, the reduction would be more than 11.5%. This means that rooftop solar power would become cost competitive for residential consumers in the states of Delhi, Karnataka, Haryana, Punjab if these states opt for the municipal bond approach. The recent municipal bond (taxable) issued by Pune Municipal Corporation has a coupon rate of 7.59%. If a similar coupon rate is assumed for municipal rooftop solar bonds, then the reduction in the cost of solar power can be even greater than 11%.

A study conducted by Climate Policy Initiative (CPI 2016c) showed that domestic investors including institutional investors, non-banking finance companies (NBFC) and development finance institutions have a total debt investment potential of USD 56 billion to be channeled to renewable energy in India.

Even if the bonds are issued as taxable instruments, the relatively better credit rating of the municipal corporations is expected to make their borrowings cheaper than that of the solar developer. For example, recently, Pune Municipal Corporation (PMC) raised a bond at a coupon rate of 7.51% and New Delhi Municipal Corporation (NDMC) announced its plan to raise a bond via nonconvertible debenture (NCD) route and is expecting similar coupon rates. Both these municipal corporations are being rated AA+ by credit rating agencies and hence have a competitive cost of debt. ii Issuance of municipal bonds enhance the capacity of local governments to access capital markets Given that rooftop solar projects have become commercially feasible in India, raising municipal bonds for such projects is attractive for municipal governments interested in accessing capital markets for a broader range of projects, as well as for prospective investors in these bonds. This model will be a good proof-ofconcept for municipalities to build their capacity for future bond and capital market-financed projects

Solar power generation projects provide a relatively stable stream of revenues for longer duration via PPAs. This will attract investors, especially institutional investors who prefer longer, stable and predictable returns on their investments. Hence, a significant amount of untapped investment can be unlocked for rooftop solar through the municipal bond route. Municipal bonds issued in the past have been able to attract large domestic institutional investors (DIIs), such as provident funds, insurance companies, mutual funds, and commercial banks, irrespective of the projects for which the bonds were raised. Hence, investments from these DIIs can be mobilized into the rooftop solar segment via municipal bonds. As they will be issued for clean energy projects, municipal bonds for rooftop solar will be green bonds that can attract additional classes of investors such as the dedicated green bond funds, private and public investors and multilateral organizations. India is already among the top ten largest green bond issuers in the world, with the majority of proceeds (76%) allocated to renewable energy projects. Hence, the proposed bond can be labelled as ‘green’ municipal bond to tap these additional classes of investors 

surplus status and hence capacity addition might slow down in these states.

Policy Scenario remains supportive amidst strong growth across segments The Ministry of New and Renewable Energy (MNRE) announced a new policy providing incentives to distribution companies for commissioning rooftop solar projects. One of the biggest hurdles in accelerating rooftop solar deployment has been the reluctance of utilities in providing timely approvals and grid connections. Under this policy, DISCOMs would be given a monetary incentive for achieving pre-set targets of rooftop solar additions. Besides this, ambitious bidding trajectory for adding 100 GW capacity of utility solar energy has also been laid down for the next three years. Major schemes for implementation of Solar Park, Solar Roof Top Scheme, Solar Defence Scheme, Solar scheme for CPUs Solar PV power plants on Canal Bank and Canal Tops, Solar Pump, Solar Rooftop etc. havealso been launched over the last two years.

The capacity of “Development of Solar Parks and Ultra Mega Solar Power Projects” scheme has also been doubled to 40,000 MW. India has distributed 28 crores LED bulbs over the last three years and has launched the ‘Atal Jyoti Yojana’, to benefit over seven million school going children under the Solar Study Lamp Scheme.

The Rooftop Solar Segment is seeing a strong push by the government The government of India has been aggressively promoting rooftop solar in the country as India suffers from a paucity of land and high real estate prices. The government recently implementedthe“Grid Connected Rooftop and Small Solar Power Plants”program which will aid in the installation of 2100 MW capacity through Central Financial Incentive (CFA)in the residential, social, Government/PSU and institutional sectors. Moreover, concessional loans for solar rooftop projects amounting to $1,375 million have been granted to leading PSU banks in India like State Bank of India, by multilateral

The government has also proposed a new scheme“Sustainable Rooftop Implementation for Solar Transfiguration of India” (SRISTI), to provide financial aid of INR 23,450 crore for 40,000 MW of rooftop solar installations.As per this program, a maximum subsidy of INR 18,000 per kW will be provided to the residential sector, while INR 5,500 per kW will be given for all social, institutional, government and commercial sectors.India has planned to install 100 GW of solar power by 2022, out of which 40 GW will be rooftop solar installations. However, the country has achieved a meagre 1.6 GW of rooftop installations as of December 2017.

According to the Rooftop Solar

Map 2017 by Bridge to India, Tamil Nadu had the largest rooftop solar capacity with 163 MW, followed by Maharashtra with 137 MW and Rajasthan with 88 MW as of March 2017. According to Bloomberg New Energy Finance, cost of electricity from rooftop solar has nearly halved in the last five years. The Railway Minister launched Mission 41k energy plan for Railways, which is expected to save INR 41,000 crores over the next decade by changing the overall energy mix of trains by using more renewable energy sources like solar and wind energy. 11 railway stations in Palakkad and Thiruvananthapuram divisions have decided to install rooftop solar panels withtotal capacity of 390 kW to reduce their electricity bills. It is expected that the installation could reduce electricity tariff from INR 8.10 per unit to INR 3.64


per unit for 25 years.The Indian Railways have adopted solar in a big way setting up solar panels at the rooftops of its offices and railway stations. Another new and laudable step undertaken by the southern hi-tech city of Bengaluru is the application of light detection and ranging (LiDAR) technology to map the rooftop solar potential of the city. The city aims to generate 1,000 MW of rooftop solar energy by 2022. Such initiatives will be directed towards assessing on ground risks and true potential, and eventually aid in developing a clear and actionable plan to achieve this target.

Key Solar States driving the solar revolution in India The major renewable energy rich states in India are Tamil Nadu, Rajasthan, Karnataka, Andhra Pradesh, Maharashtra, Gujarat, Himachal Pradesh and Madhya Pradesh. The state with the highest solar installations in 2017 was Telangana followed by Karnataka, Andhra Pradesh and Rajasthan.Karnataka, Andhra

Pradesh, Tamil Nadu, Telangana, Rajasthan, Madhya Pradesh and Punjab together accounted for 80% of India’s total installed capacity. While Karnataka, Andhra Pradesh, Tamil Nadu, Telangana and Rajasthan have added more than 3 GW of solar capacity each, Madhya Pradesh and Punjab have added another 2 GW and 1 GW respectively. Karnataka Karnataka leads Maharashtra, Uttar Pradesh and Gujarat in terms of installed as well as tendered pipeline capacity. That state installed a whopping 2 GW of solar power in 2017. The state has also upwardly revised its solar installation target to 6000 MW by March 2021 out of which 40% will come from rooftop solar installations. Karnataka’s estimated solar power potential has also been increased to 24.7 GW from 20 GW earlier. The state is regarded as having one of the friendliest regulations and policies towards distributed solar generation. The solar policy in Karnataka encourages public private participation in this sector, solar rooftop generation and decentralized generation where grid is inaccessible. Karnataka is also inspiring farmers to lease their land for wind and solar farm

development. The state recently inaugurated the first phase of the world’s largest solar park of 2000 MW capacity spanning across 13,000 acres. Telangana Telangana is another southern state that installed 2 GW of solar power in 2017. The state has shown tremendous growth in surpassing leading solar states like Gujarat to becomethe second largest solar state in India currently. Telangana recently crossed the 3 GW mark in the first quarter of 2018 becoming one of the first Indian states to surpass 3 GW mark intotal solar installations. Telangana is focusing on a distrib-

Cover Story uted development model rather than accelerating solar installations through the solar park approach. The state’s decentralized solar power policy has helped in attracting solar developers and reducing transmission losses. It is planning to generate 5,000 MW solar powerby 2019. Telangana hashuge solar potential and is targeting to install 2,000 MW of rooftop solar by 2022. Favourable state policies like reducing red tape in government departments through fast approvals and 100% refund of VAT, GST, stamp duties etc. have ensured support for solar installations. The state has in a few short years of its creation become a solar superpower through enactment of progressive policies and rapid execution. The addition of large solar power capacities has not only reduced the power deficit but also helped in keeping the prices of power affordable. Andhra Pradesh Andhra Pradesh is another leading solar state. For comparison sake, Andhra Pradesh’s power consumption is only one-third that of Maharashtra, but its installed solar capacity is three times in comparison. The state has plans to achieve at least 5000 MW of total solar power capacity addition over the next five years. Its solar policy aggressively supports developing solar parks as well as distributed generation hand-in-hand. The state government is promoting solar installations on the rooftops of public buildings, commercial and industrial establishments on gross and or net meter basis. Andhra Pradesh solar policy also provides incentives in the form of exemption of transmission and distribution charges and losses, cross subsidy surcharge, electricity duty for captive consumption etc. Andhra Pradesh has seen a large number of industries adopting solar power as it has become cheaper than buying grid based power.

Rajasthan Rajasthan has the highest solar potential in India due to its vast land area which is mostly uninhabited and also receives very high solar radiation. The state has the potential to become a major solar power generator as well as exporter of this power to other states. The state government announced its solar energy policy in 2014 to add an additional capacity of 25,000MW in Rajasthan. The state also has Net metering scheme to promote rooftop generation. Jodhpur has the maximum projects in the state. Rajasthan’s 500 MW Bhadla solar park witnessed record low winning bids of INR 2.44/ kWh by Acme Solar Holdings Pvt. Ltd and SBG Cleantech Ltd. Gujarat The 2009 solar policy of Gujarat has a target for solarinstallations of upto 1 GW. However, there is a drawback in the state’s solar policy that permits only home owners to set up rooftop solar plants to take benefit of all incentives, and not allowing leasing of roofs. Gujarat which was once the trailblazer in solar capacity additions has slowed down as the state became power surplus. Gujarat under the current PM had installed a large number of solar power plants at relatively high rates. This made the distribution utilities reluctant to buy more solar energy. This allowed other states particularly

46 SmartEnergy March/ April 2018

the power deficit states of the south to lead the march. However, Gujarat has again started to add more wind and solar power over the last year and is planning to add 250 MW over the next couple of years. Tamil Nadu Tamil Nadu accounted for almost one-fifth of India’s total renewable energy generation in 201617. Tamil Nadu has long been the leader in terms of wind power capacity in India accounting for a lion’s share of wind energy generation. Now it plans to increase the solar power installed capacity by 5,000 MW in the coming years. The state has the potential to increase its solar capacity by six times till 2027. Renewables account for more than 35% of the state’s total power generation fleet. The state also has a strong pipeline of about 2 GW of solar projects. Maharashtra The government of Maharashtra has set an installation target of 7500 MW of solar power generation capacity by 2019. Compared to other states, Maharashtra has not installed solar energy at the same rapid rates. However, the state has started to become more focused on renewable energy and has a huge potential to add more solar power. Uttar Pradesh


Uttar Pradesh is also slowly but steadily moving ahead in the solar race. The government of Uttar Pradesh has set a target of 10,700 MW for solar power installation by 2022 and projects to source 8% of its power needs from renewable energy sources. The state is infamous for its shoddy power infrastructure and developers are also jittery in signing new projects given the bureaucratic lethargy in the state. Recently, UP’s largest solar power plant was inaugurated by Prime Minister Modi and French President Emmanuel Macron. The 75 MW solar power plantwasbuilt at a cost of around INR 500 crore by French firm ENGIE, spanning across 380 acres of land. Chandigarh Chandigarh has been named as the rooftop solar capital of India. The Union Territory had issued a notification making installation of solar panels mandatory on the rooftops of residential houses measuring 500 square yard and above as well asgroup housing societies.Installation of rooftop solar power plants was made compulsory for new construction and the owners of existing houses were given two years to comply with the direction. With only two months left for the twoyear deadline to expire, the Chandigarh administration is all set to issue notices to owners to have failed to comply. According to a survey conducted by BTI, the industry voted for Madhya Pradesh, Andhra Pradesh and Gujarat as the top three states in ease of doing business for solar projects, while Uttar Pradesh, Maharashtra and Tamil Nadu were ranked as the least attractive. Karnataka, Andhra Pradesh and Telangana were voted as the top three states on attractiveness of their open access solar market. India is amongst the few countries to host some of largest solar power plants andalso has the highest solar electricity production

per watt installed. The 648 MWKamuthi Solar Power Project, Tamil Nadu is worth mentioning here. The plant was built in a record time of eight months and is the largest solar plant at a single location, which can provide enough electricity to power 150,000 homes. Kurnool Solar Park in Andhra Pradesh has emerged as the world’s largest solar park. With 1000 MW capacity, the park is fully commissioned and operational. 35 solar parks of total capacity exceeding 20,500 MW have already been approved in 21 states.As a result of capacity enhancement under Solar Park Scheme last year, three new solar parks were approvedinRajasthan, Gujarat and Mizoram with total capacity exceeding 1500 MW.

Risks & Challenges As per Indian government’s Make in India policy, domestic solar companies have been encouraged to manufacture solar components and equipment in India. However, cheap imports from China and other neighbouring countries have almost completely captured the domestic market with a share of more than 90%. The government of India has therefore, proposed a 70% preliminary safeguard duty and 7%+port duty on imported modules. This has created regulatory uncertainty in the country and developers are afraid of signing new PPAs or making further commitments. The other major risk is regulatory uncertainty around the Goodsand Services Tax (GST) which qualifies modules for a concessional rate of 5%, but there is still no clarity around rates on other equipment. Overall, the country suffers from a lack of a clear and unified solar policy vision. Often government policies are conflicting in nature which leaves developers in a state of confusion. The country still has to install 80 GW

in the next five years and inconsistent policies might imposechallenges to further growth of the industry. Other than that, the continuously falling price of solar projects has led to cancellations of several on-going solar tenders. For example, 2017 witnessed states including Uttar Pradesh, Andhra Pradesh and Tamil Nadu renegotiating projects which were previously allotted at higher tariffs. Not even one PPA has been signed for the 1 GW Jharkhand solar tender. As prices continue to fall, solar will become more and more financially lucrative. It will not only become attractive from theenvironmental perspective but will also become an attractive investment proposition in the long run. As the solar market matures, the government will slowly withdraw all the incentives. The truth is that even if MNRE makes guidelines, the real power to enforce those lies with the state DISCOMs. In order to achieve the 8% RPO target by 2022, the MNRE has allotted state targets, but state’s performance has not been very impressive so far.

Conclusion Though the government is trying hard to promote solar aggressively, some of its policies still lack clarity and structure, which has led to a slowdown in installations. It is imperative for the Indian government to implement policies that remove uncertainties for the industry and create an environment conducive for solar growth. The government needs to realise that the largest renewable capacity expansion program is being taken up by India, globally. Currently, renewable power in the country constitutesaround 18% to the total installed power generation capacity. The government’s target is to take this figure to 40% by 2030 as per its global climate change commitments 

Quality & Performance



he verification of system performance and energy output from the panels is particularly important and a major reason why periodic verification and testing of the system can also be very important – as well as being essential to comply with warranty and PV system guarantees. Seaward Solar offers PV installation testers that provide a complete solution for Solar PV electrical and environmental testing. The absolute minimum testing that needs to be undertaken involves continuity measurements, open circuit voltage, short circuit current, insulation resistance and irradiance. Other tests involving the use of I-V curve tracers and power analyzers are very useful to carry out certain diagnostic testing or to assess different performance parameters of the solar PV system. One important parameter that stands out and needs to be tested to ensure the health of the PV system is the I-V curve.

Pre-installation Testing the modules prior to installation saves time in the long run and helps during troubleshooting at a later date. It also gives an indication of the power output prior to installation so that the LID (Light Induced Degradation) effect can be monitored.

Commissioning Taking an I-V curve of an array at the commissioning stage gives us a benchmark for future comparisons. It also helps the commissioning team to diagnose

issues before going off site thus saving return visits. The PV200 from Seaward can perform all the required solar PV commissioning tests included in IEC 61829 and IEC62446.

Ongoing Operation and Maintenance Loss in power generation can be noted and understood by measuring the I-V curve of an array. Testing the string can identify issues at the modular level and this can help in saving a lot of time on the site. The Seaward PV Mobile App has been designed so that the curve report can be emailed directly from the field. The PV200 Solarlink Test Kit is an all-in-one tool that can perform all commissioning test requirements of the IEC 62446:2016. It holds the secret to making PV testing more efficient, easier and safer. Solarlink connectivity between the PV200 tester and Solar Survey 200R irradiance meter, allows the results from the irradiance, module and ambient temperature from the 200R to be transmitted over a wireless link and be recorded in real time in the PV200.

as testing its electrical output, to know whether it is working to its potential under the existing irradiance levels. If the electrical output is different from the manufacturers’ quoted values, it must be determined whether this is due to a fault in the PV installation, or simply because irradiance was different from STC. This is very important for I-V curve tracing where the accuracy of irradiance data, including the changes in irradiance during a test, are very important. The PV200 tester is the only hand held PV electrical test instrument on the market offering short circuit current, open circuit voltage, insulation resistance, earth continuity and I-V Curve tracing functionality.

I-V Curve Tracer for the health of your PV Module The electrical power produced by a solar PV cell or module is a function of the current (I) and voltage (V) characteristics. Measuring the relationship between current and voltage whilst varying the electrical load connected to the PV cell

The electrical output will vary significantly with changes in the level of in-plane irradiance. Solar PV panel manufacturers quote the electrical output at standard test conditions (STC) with an irradiance level of 1000 W/ m2. Therefore, when commissioning a PV system, it is necessary to measure the level of irradiance at the same time

Use I-V Curve technology for maintaining your power plant Solar module datasheets show I-V curves that give an indication of the maximum power output of the module at Standard Test Conditions (STC). This reading is taken in the PV manufacturing plant under laboratory conditions. By using a handheld I-V curve tracer and intelligent software, it is possible to transpose the I-V curves in the field to the STC levels. These curves can then be compared in order to get an indication of the

Power is the product of voltage and current and so the power vs voltage curve shown can be generated from the measured voltage and current data. The power vs voltage curve shows the point at which the power is a maximum (Pmax). The corresponding maximum power point Mpp is shown on the I-V curve. Loading the PV module such that the current is Impp and voltage is Vmpp will operate the PV module at the maximum power point (Mpp) and result in the maximum power generation.

Voltage plant’s predicted performance vs its actual performance. Hundreds of units of PV200 have already been supplied all over India to leading EPCs and module manufacturers like L&T, Adani, Suzlon, Renew Power and Azure Power etc. There are many instruments available on the market that are sold under the title of Solar Testing so it is vital to ensure that the instruments selected are capable of performing all of the tests required by the IEC 62446 standard. The nature of PV testing is such that it can expose the installer to high voltages, so the selection of an instrument, which is capable of automatically, and safely performing tests greatly improves efficiency and safeguards the installer. The availability of new multipurpose solar PV test instrumentation also means that the functions of a number of individual test instruments can be combined in a single tool – with consequent sav-

Simultaneous measurement and recording of irradiance, open circuit voltage (Voc) and short circuit current (Isc) is required for the PV Array Test Report for IEC 62446. While many of the more reputable and discerning solar PV installers recognize the importance of testing to the standard, it is of serious concern that some installers are failing to perform the required tests, or at best only partly fulfilling this obligation.

View Point

Scaling up Renewables for the 'Make in India' growth story


he scaling up of Renewable energy is imperative to the success and growth of the ‘Make in India’ initiative. With government’s thrust, the country is experiencing positive winds of change in the Energy sector particularly in Renewables. Clean energy sector is already contributing ~13% of India’s total installed power capacity which is mainly driven by over 32 GW of Wind power. The government has set an ambitious target of 175 GW of Renewable energy capacity by 2022 in order to provide 24/7 power to all and achieve energy security in an environmentally sustainable way. Indeed, India has the potential and capability to lead the global transition to renewable energy sources and become the renewable energy technology hub to the world. What we require now is policy predictability and execution. I believe, renewable industry can play two pivotal roles in actualizing the vision of ‘Make in India’ initiative. ii India can be transformed into a manufacturing hub for renewable energy technologies: There is enormous scope for indigenizing technology and component manufacturing. India is still heavily reliant on imports especially for Solar PV cells and other components. By securing the supply chain for Wind, Solar and other Renewable technologies in India, we can not only reduce the cost of these technologies, but also create value additions and employment in the country. This would act as a GDP multiplier as seen in Europe and China ii Renewables energy is key to competitiveness of Indian manu-

facturing and exports. Take any major Industry in India, power constitutes as a critical input and cost. Owing to rapidly declining cost of energy from renewables, renewable energy sources such as Wind is less expensive than the prevailing commercial or industrial tariff. In fact, many corporates, Public sector units and Small and Medium enterprises such as in textiles have already tapped the benefits of Wind power to hedge their energy costs. Indian industries can hedge 25 years of their energy costs by investing into Wind or Solar. Therefore, to develop a strong manufacturing and export base with global competitiveness, we need large scale renewable energy base in India.


I suggest some key measures to boost renewable energy and wind energy in particular.

The success of ‘Make in India’ needs long term and integrated policy approach amongst all stakeholders- India Inc, policy makers, and academia amongst others. I am confident, with a collaborative approach the Indian renewable sector will grow manifold and India can emerge as the innovation and manufacturing hub for renewables.

ii Availability of grid and land infrastructure at state level is a concern and the state governments need to invest in that area well in advance based on available wind and solar resources in the state. ii Renewable energy needs largescale funding so Banks and Financial Institutions should earmark a certain percentage of finance for Renewable Energy projects and finance should be available for longer period of 20 years. This will ensure lower cost of energy which will benefit the end consumer. ii Renewable Energy is the key catalyst for economic growth of our country and development of renewable energy such as Wind is vital to attract domestic manufacturing in the country, rural employment through projects and operation and maintenance

52 SmartEnergy March/ April 2018

ii It is imperative for the industry players to raise the quality standards and asset value optimization efforts. From the Wind energy perspective, we need to introduce many more innovative products that can harness energy from low wind sites at a competitive cost. Turbines with advanced control systems, improved scheduling and forecasting, digitally controlled smart grids and storage systems are also required in order to smoothen out variability. ii We have numerous opportunities to bring down the life cycle cost of energy from wind further by leveraging technology and optimizing supply chain.

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.

The flawless manufacturing facilities coupled with a highly functioning research and development cell ensures that we stand at the forefront of battery and solar services. Eastman Research and Development Cell is the offspring of this respect for the pursuit of a better life through innovation with the aim to propagate a culture of curiosity and innovation.



.As a panel manufacturer what are your views on the proposed safeguard duty on imported solar cells and modules? How do you see the safeguard duty affecting the solar sector in India, more particularly on project developers, manufacturers, innovation, R&D, and Make-in-India? The Central Board of Excise and Customs has sought to reclassify imported solar panels and modules in a category that attracts 7.5% duty and various kinds of cest with the cost of a solar cell, around 30 cents at present, will go up to around 50 cents for Indian developers if 70% safeguard duty is imposed. The cost of solar power will accordingly go up to around Rs 7 per unit. The market share of imported solar equipment widened to 90% from 86% in this time, while that of domestic manufacturers shrank to 7% from 13% as India’s solar programme expanded dramatically, with Prime Minister Narendra Modi setting an ambitious target of 100,000 MW of solar capacity by 2022. India’s solar capacity was about 15,600 MW at the end of October. We think domestic solar industry is faced with a significant loss of potential employment and innovation opportunities with manufacturing units and R&D. This could also act as a roadblock in the Make in India initiative in the power Industry.


.In addition to the proposed safeguard duty what are your suggestions to make India a global manufacturing hub for solar products? India is blessed with ample amount of sunlight so there is a great scope for the solar industry in India. India is in the process to achieve one of the most ambitious solar targets globally of 100 GW by the year 2022. The recent years have been marked by a number of remarkable initiatives from the government such as “Make

in India” and ramping up of the solar target. The solar mission can only be successful if the domestic manufacturing sector is also developed. Currently the solar module manufacturing capacity is around 7.5 GW annually and the solar cell manufacturing capacity is around 1.7 GW. Currently 85-90 per cent of the solar module installations are from China. Such high volumes of imports lead to a forex outflow of approximately INR 20,000 Crore or USD 3 Billion. If unchecked, this is expected to increase to USD 20 Billion by the year 2025. Introducing favourable policies for domestic solar manufacturing, driving innovation through R&D support in the sector, focusing on skill development - are few of the many steps that Indian solar industry drastically needs for growth. Incentivizing manufacturing will also make sure that India continues to remain a leader towards fighting climate change post COP21 agreement in Paris. Undoubtedly, Indian market is showing an incredible growth rate, but we are still in infant stage when compared to countries like China and US that already dominate huge parts of the solar product supply chain. Given the huge potential of India, it is important to compete with these countries to claim a larger share of the industry, cashing in on the growing green energy growth and initiate socio-economic reform in the country.


.Shed some light on the range of Solar Inverters you manufacture? The key features and differentiating factor? We have various types of solar solutions i.e. the MPPT, GRID-TIE inverter and the Solar Pulse Width Modulation Technology GRID-TIE inverter is an energy system that allows for uninterrupted power flow to the appliances in an organization or home. The Grid-Tie generates electricity that is converted to usable AC

EAPL provides batteries for vehicles, Inverters & UPS systems applications as well as E-rickshaw and solar solutions.


electricity and then powers the connected loads through the main supply inlet. In the case of extreme low sunlight condition, the system then runs the load through the main power supply. Hence, it works as a fail-safe method to ensure proper power throughout the day for any connected place. The main feature of the Gridtie inverter is that during times when solar energy produced by your inverter is not utilized to run the load, it will not let it go waste instead it feeds the power back to the utility grid thus reducing your electricity bills and often leading to additional electricity units in your account that can be used in the next month. MPPT generates electricity from a solar PV array and then stores it using specially designed solar batteries after regulating the produced electricity through a charge controller, which is inbuilt in the MPPT PCU. With the latest innovations in every part of the product, the Eastman MPPT guarantees the best possible services. The system is optimized to gain the maximum possible power from the solar panel system with the highest tracking efficiency of greater than 98%. This is the best choice for residential homes and commercial establishments. The Eastman PWM range comes with the highest efficiency in its class and provides the ability to generate your own energy while using a low-maintenance, silent and pollution-free method. While solar energy usage is always the

.How do you look at the market and key challenges for Energy Storage in India? Traditionally, in India, energy storage for commercial purposes has been done using lead acid or similar systems, which though have a mature technology, suffers from poor conversion efficiency, higher maintenance, negative environmental impact and shorter life. Thus, more efficient and smart energy storage system which completely or partially eliminates all the above drawbacks of the legacy system needs to be incorporated for better utilization of resources. Looking into this Eastman has introduced the Gel technology based batteries that have higher efficiency and low maintenance, we aim to develop more such innovative technologies in future.


.Going forward what are the technology trends that are likely to be drivers of growth for Solar Inverters? How is EAPL preparing for the new opportunities? The confluence of powerful trends
