INDIA’S MNRE SEEKS INNOVATION IN SOLAR PUMPS DESIGN AND COSTS The Ministry of New and Renewable Energy (MNRE) had issued updated specifications for stand-alone solar pumps on 17.07.2019 and since then the Ministry states that it has received representations from innovators claiming that by using different design/software for the stand-alone solar pump they can achieve performance better than specified by the Ministry in a cost effective manner. At present under MNRE Scheme stand-alone solar pumps fulfilling MNRE specifications can be installed, however, in order to promote innovation in technology, the Ministry has decided to permit installation of innovative stand-alone solar pumps in test mode.

YINSON ACQUIRES 37.5% STAKE IN INDIAN POWER PRODUCER Yinson Holding Bhd signed up multiple agreements in order to acquire 37.5% equity interest in Rising Sun Energy Pte Ltd which currently owns two operational solar plants in the Bhadla Solar Park, Rajasthan. The agreements were entered through Yinson’s unit, Yinson Renewables (S) Pte Ltd. “The group will pay 554 million rupees (RM32 million) for the stake, subject to closing conditions, while also providing funding of 600 million rupees (RM35 million) to repay certain outstanding liabilities of Rising Sun Energy,” the energy solutions provider said in a statement today. The two adjoining solar plants have a combined generation capacity of 140MW (AC rated) and achieved their scheduled commissioning dates in 2017. Rising Sun Energy has signed 25-year power purchase agreements, expiring in 2042, with India’s largest power utility, NTPC Limited, which is majority owned by the Indian government.

CORONAVIRUS UPDATE: RENEWABLE ENERGY PROJECTS MUST-RUN SAYS INDIAN MNRE The Ministry of New and Renewable Energy (MNRE) has issued a notice to Discoms stating to clear their dues regularly as was being done before the lock down and the notice also states that they should continue to buy power from renewable energy producers. According to the notice, the power ministry has recently issued instructions providing a moratorium to Discoms for making payments to electricity generating companies in the wake of the COVID-19 outbreak. Some state Discoms, however, used that order to start curtailing renewable energy power(Partially or completely) terming the prevailing situation a ‘force majeure’ condition.

"MIDDLE EAST AND AFRICA ARE THE NEW FOCUS AREAS FOR LONGI AND A LOT OF MANPOWER IS BEING RECRUITED FOR CONDUCTING BUSINESS IN THIS REGION." Mr. Pradeep Kumar, Director of Business, Longi Solar Technology Co. Ltd. WHAT IS THE MODULE PRICE GUIDELINE FOR THE NEXT FEW QUARTERS? HOW HAS BEEN LONGI’S JOURNEY IN THE INDIAN SOLAR MARKET? Longi has been in the Indian solar industry for the past four years. In the early years we did not have a big team in the country. The situation has now changed and the solar market in general has shown a growing preference for the LONGi Hi-MO 4 module with M6 wafer (166mm). We have a full-fledged team now to handle a large portfolio of projects. The total deployment of our modules so far has been around 1.25 GW. This capacity is already operational and all our customers are extremely happy with the performance and service of our products. Now we are signing up for larger contracts. We aim to be number one in India by end of year 2020, targeting atleast 4 GW of business by catering to most of the module requirements for esteemed projects to be executed by top project developers in India. We have already booked orders for 2.6 GW in the initial two months of calender year 2020, primarily for dispatches in Q3 and Q4. India is a very strategic and promising market for us and we hope to do good business here in coming years.

WHAT HAS BEEN THE PENETRATION OF MONOCRYSTALLINE TECHNOLOGY IN THIS MARKET? Indian EPCs and developers have started deploying modules made using monocystalline technology for most of their upcoming projects. Higher efficiency with lower degradation levels, combined with other advantages have made this technology the most reliable and feasible solution for all big projects in India and across the globe. We are now signing contracts for the supply of mono PERC modules for very large projects with top developers and EPCs in India. The market size for this technology can be gauged from the fact that if 10 GW of solar capacity will be deployed in India in the year 2020, we feel around 7-8 GW will be based on monocrystalline technology. In reality, it might be even more.

WHAT IS LONGI’S PLAN TO MANUFACTURE MODULES IN INDIA? Longi has a strong manufacturing presence in China across the PV manufacturing value chain, right from ingots and wafers to cells and modules. We also have very aggressive plans for manufacturing modules in India and have been exploring all possible business models to do so. We have short listed two strategies so far and will soon decide which one is the most feasible option for us. So, you may hear a big announcement from LONGi shortly once we finalize the right option. The intention is clear that we want to set up a factory in India, be it directly or through a joint venture. As we see that the future for solar is very bright for India, setting up a factory here will definitely help us to diversify capacities and help us in catering to the module requirements of India and other potential regions across the globe.

SOLARQUARTER | APRIL ISSUE 2020

There are two major PV technologies in India currently. Polycrystalline - which is the most widely adopted, and monocrystalline- which is fast gaining traction. There exists a price difference between the two technologies. Monocrystalline technology continues to charge a premium over polycrystalline due to higher generation and better reliability offered by the former. We will continue to have a competitive pricing strategy for India.

BEYOND MONOCRYSTALLINE, WHAT IS THE PV TECHNOLOGY OUTLOOK IN INDIA? Technology outlook depends a lot on its acceptance in the Indian market. Bifacial, by all standards is a better product compared to monofacial modules. The only challenge for bifacial pertains to economies of scale – the more the volume, the better will be its pricing and suitability for a project. In the initial stage, a few developers are accepting a small risk of taking a trial of this technology which we have already been discussing with them. Some developers are already deploying our bifacial modules for a smaller volume of their projects, which is a positive sign. Once these trials are completed, the difference between mono and bifacial will be evident. In markets like Middle East, the sector has already shifted to bifacial as it is highly successful in their natural conditions. We are hopeful that Indian solar market will also shift to bifacial technology on a large scale by 2021.

Longi has been in the Indian solar industry for the past four years. In the early years we did not have a big team in the country. The situation has now changed and the solar market in general has shown a growing p r e f e r e n c e f o r t h e L O N G i H i - MO 4 m o d u l e w i t h M6 w a f e r (166mm). WHAT ARE YOUR VIEWS ON CUSTOMS DUTY AND SAFEGUARD DUTIES IMPOSED BY THE GOVERNMENT? There is not much clarity on what has been the government’s intent – whether it is about imposing Basic customs duty (BCD) or about the continuation of safeguard duties after August 1, 2020. We expect clarity as well as uniformity on these from the government. We are hoping for fair play – if basic customs duty is imposed on any manufacturer, it should be uniform across Indian and foreign manufacturers. This will promote healthy competition in the market -purely based on the capacities and capabilities of the manufacturers. It has to be a strategic call by the government. As far as safeguard duties are concerned, they will most likely be removed this year.

PG 8

WHAT ARE THE OTHER KEY ISSUES FACED BY SOLAR MANUFACTURERS? There are not many significant hurdles but we certainly need clarity regarding BIS certification norms and MNRE’s decision to enlist models and manufacturers on the Approved List of Models and Manufacturers (ALMM). We are happy to be a part of such processes that is being implemented; the only expectation is to have early clarity on these processes because it has a direct impact on the pace of project implementation. This in turn will not just affect solar revenue generation but also the orderbook of manufacturers as developers will need to postpone the contracts to comply with the new regulations. Another challenge pertains to the sudden increase in modules demand for projects that got postponed due to PPA issues in states like Andhra Pradesh and Telangana as well as those that were lined up for commissioning in the quarters ended September and December. It is estimated that atleast 5-6 GW of modules will be coming to Indian ports between June December 2020. This will create a big rush for clearances at the ports and inland logistics, which we feel is going to pose a challenge for the manufacturers as few developers might decide to delay the shipments to avoid this congestion. If there exists such delay, it will hit the revenues of module manufacturers and also create an imbalance in demand and supply forecasts.

WHAT IS LONGI’S SHARE IN THE UTILITY AND ROOFTOP SOLAR SEGMENTS IN INDIA? LONGi has been strategically growing its base in India. Until last year, we were not very aggressive as polycrystalline was a dominant technology. Acceptance of monocrystalline technology has picked up tremendously this year and we are set to scale up our market share. In 2020, we expect to have 30 per cent market share in the utility-scale segment and between 10-15 per cent in the distributed solar space (including rooftop).

HOW HAS THE COMPETITIVE LANDSCAPE FOR MONO PERC EMERGED IN INDIA? In India, our key competitors for monocrystalline technology are Jinko Solar, Ja Solar and Trina Solar. A few domestic manufacturers are also producing monocrystalline modules but their scale of production is too small in comparison. As of now, there exists a healthy competition for mono PERC in India.

WHAT OPPORTUNITY DO YOU SEE IN NICHE SEGMENTS SUCH AS FLOATING AND HYBRID SOLAR? We have been in discussions for a 70 MW floating solar project coming up in India. The potential for such projects is big in India but their implementation is not so easy. The technology for floating solar projects is mostly imported from countries like China or Spain and the onground issues in India are different from those countries. It is just the initial phase and the technology might get proven by next year. Once that happens, the floating market is likely to pick up as the potential is huge and issues like land constraints do not apply to this segment. As far as modules are concerned, we have a substantial advantage in this space as LONGi has worked on a number of floating solar projects globally. We have supplied modules for the biggest floating solar project (150 MW) in China which was developed by Sungrow. We can bring in that experience on board and share it with local developers in India. In the hybrid projects space, there seems to be a lot of development. Many large-scale developers are working in this space on solar-wind projects as well as storagebased set ups. The government is pushing this segment and hence we see a significant opportunity in this market in the coming days. We will be supporting such projects both technically as well as in terms of high quality equipment supply and good service.

SOLARQUARTER | APRIL ISSUE 2020

WHAT ARE THE NEW MARKETS THAT LONGI IS FOCUSING ON BESIDES INDIA? Middle East and Africa are the new focus areas for LONGi and a lot of manpower is being recruited for conducting business in this region. Middle East is emerging as a promising market with some very largescale tenders coming up in the region. LONGi is already working closely with the key developers in the region.

LONGi has a strong manufacturing presence in China across the PV manufacturing value chain, right from ingots and w a f e r s t o c e l l s a n d m o d u l e s . We also have very aggressive plans for manufacturing modules in India and have been exploring all possible business models to do s o . We h a v e s h o r t l i s t e d t w o strategies so far and will soon decide which one is the most feasible option for us. So, you may hear a big announcement from LONGi shortly once we finalise the right option. WHAT IS LONGI’S OUTLOOK FOR THE INDIAN SOLAR MARKET? Indian solar market is very promising for a manufacturer like us and will remain a key focus area. We have a clear intent of being invested in this market and are thus exploring the opportunity of setting up a manufacturing base here. We are here in this market for the long run and would be very happy to contribute to the renewable energy mission set by the Indian government.

Technology outlook depends a lot on its acceptance in the Indian market. Bifacial, by all standards is a better product compared to monofacial modules. The only challenge for bifacial pertains to economies of scale – the more the volume, the better will be its pricing and suitability for a project.

"WE ARE ADEPT AT LEVERAGING PEOPLE, PROCESS, AND TECHNOLOGY FRAMEWORK FOR ENSURING CONTINUOUS IMPROVEMENT." Mr. Vineet Mittal, Chairman, Avaada

WITH AWARDED PORTFOLIO OF MORE THAN 4000 MW IN INDIA AND AFRICA, WHAT ARE YOUR FUTURE PLANS?

WHAT YOU SEE FOR THE FUTURE OF THE INDIAN PV MARKET?

Avaada Energy has scaled up rapidly and within 2 years of establishment, it has ~1000 MW of capacity under operation. The firm has created a solid pipeline of another 3000+ MW which shall be implemented over next few year. We plan to have installed base of 5 GW by 2022 and 11 GW by 2025.

I strongly believe that future of energy is renewables. The world is going through energy transition and India is at forefront and is one of the leaders. It is presently 3rd largest market for Solar PV plants globally. The long- term prospects look promising. With 34 GW of operational capacity, solar is poised for further expansion. Decline in tariffs has made solar competitive and is one of the fundamental drivers for acceleration in adoption of solar. Amid climate concerns, there is no coal-based capacity planned in last 5 years.

WHAT DO YOU BELIEVE IS THE USP OF YOUR ORGANIZATION? WHAT ARE THE BEST PRACTICES ADOPTED BY YOU? We don’t believe in USP. We believe in nurturing family culture in organisation – thus every member of organisation believes in shared ethos and value system which is being practiced earnestly. This has been one of the basic reasons that a highly competent and experienced team is working together for last 10 years. There has been negligible attrition over some many years. we strongly believe in 3 principle as mentioned below: What gets measured, gets managed, gets delivered Inspect what you expect What get rewarded get repeated We are adept at leveraging people, process, and technology framework for ensuring continuous improvement. With strong foundation of family culture, strict adherence to governance principles, and dynamic framework for evaluation for performance improvement we have managed to build a strong organisation which has exceptional expertise in Engineering, Procurement, Construction and O&M.

We expect trend to continue as people collectively are realising importance of sustainable development. Govt. of India has also shown its intent and commitment as they plan to achieve 100 GW solar capacity by 2022 and 300 GW by 2030. Further, going by trends in technology, hybrid solutions comprising of solar, wind and storage will become cost competitive and would be able to meet base load which will obviate need for coal completely. We also foresee domestic manufacturing of modules to scale up in future. Govt. is quite serious in the matter and some breakthrough measures are expected soon in the direction.

IS FINANCING STILL A MAJOR ISSUE IN THE SECTOR. IN TODAY'S TIMES HOW DIFFICULT IS RAISING FINANCE FOR SOLAR PROJECTS? Financing infrastructure projects has been quite challenging for the past few years. Saddled with high NPAs, banks have become extremely cautious. In the appraisal process, banks are evaluating risk quite closely and are looking for projects which have adequate risk mitigants like land availability, proper radiation assessment, team capability etc. Inspite of stringent due diligence, I would like to tell you that we have a strong project selection framework that we follow internally/ This has helped us immensely. I’m happy to inform you that banks have found our projects quite attractive and in fact our projects planned in Gujarat and Rajasthan have been oversubscribed.

PLEASE BRIEF US ABOUT YOUR WIND ENERGY SECTOR EXPANSION PLANS? We have developed 2 large scale wind energy projects in past and we have the required capability. There are 10 wind sites that we are monitoring continually through our won wind masts. Also, we are keeping a close eye on wind bids. , but we feel that tariffs quoted by bidders are too aggressive as there is lot of variation in wind intensity across India and should be factored suitably. Considering this, we are focussing primarily on solar, but we are evaluating wind on case to case basis. If we find an attractive opportunity that is financially feasible and meets our hurdle rate for returns, we are open to expanding into wind space.

We a l s o f o r e s e e d o m e s t i c m a n u f a c t u r i n g of modules to scale up in future. Govt. is quite serious in the matter and some breakthrough measures are expected soon in the direction.

AVAADA ENERGY - PAVAGADA SOLAR PARK

HOW WILL COVID-19 OUTBREAK IMPACT THE SOLAR SECTOR IN INDIA? COVID-19 has impacted electricity demand in the country. There is reduction of demand is by 30-35% at all India level. Solar plants have not been curtailed since tariff are lower than variable cost of coal-based power. MNRE has been extremely supportive – directions issued by Ministry to Discoms for not curtailing solar power has also helped. Thus, impact has been limited as far as generation is concerned However, there is apprehension that Discoms may delay payments which may result in increased receivables and higher working capital requirements. For alleviating the worries, MNRE has proactively taken up the matter and has issued orders to Discoms to pay promptly to RE generators. Thus, we feel RE sector will be able to tide over the present crisis smoothly.

"OUR ROLE IS TO ACCELERATE THE SHIFT TOWARDS SUSTAINABILITY BY RESHAPING THE ENERGY SYSTEM, IMPROVING RESOURCE EFFICIENCY AND PROVIDING SMART SOLUTIONS." Mr. Manoj Gupta, VP-Solar and Waste to Energy Business, Fortum India Pvt Ltd.

GLIMPSE OF FORTUM’S PRESENCE IN INDIA’S RE SECTOR? Fortum is a leading clean energy company that provides its customers with electricity, heating and cooling; as well as smart solutions to improve resource efficiency. Our role is to accelerate the shift towards sustainability by reshaping the energy system, improving resource efficiency and providing smart solutions. In India, we started our activities in 2012 with an acquisition of an operating 5 MW solar plant in Rajasthan, and with this, Fortum has created a portfolio of 685 MW (435 operating and 250 under development) solar assets in India. We have formed a Joint Venture with Numaligarh Refinery Limited along with Chempolis for setting up a bamboo-based Bio- Refinery Plant. Apart from solar energy, we are also in the business of EV charging stations, with the vertical being named ‘Fortum Charge & Drive’. As a Charge Point Operator, it has a network of more than 3000 smart chargers in the Nordic countries, out of which more than 30% are DC quick chargers. Coming to a key concern, many countries along with India already have a strict limit on the emission of nitrogen oxides; thus, NOx reduction technologies are being widely deployed. Keeping this in mind, Fortum would like to bring its own advanced time and cost saving Primary NOx reduction technology to India, which will help India in reaching its sustainability goals.

WHERE DO YOU SEE THE SOLAR ENERGY INDUSTRY IN INDIA POISED FOR THE NEXT 10 YEARS? In the long run, I believe that there is immense scope of solar power in India and it will inevitably take center stage in the power sector in 10 years' time. So far, India has contributed considerably to the energy mix when it comes to solar. Prime Minister Narendra Modi’s energy agenda has set an ambitious target for renewables. The aim is to increase renewable capacity on the grid to 175GW by the end of 2022 and 450 GW by 2030. Around 100GW of that capacity is expected to come from solar photovoltaics (PV) by 2020 and 300 GW by 2030. The COVID -19 outbreak has slowed the execution of ongoing projects however the long-term growth of the industry looks intact. Currently, the industry is facing challenges of logistics and liquidity, which will affect the renewable energy targets for this year. Owing to the plunging cost associated with solar and wind technologies as well as the anticipation of a more carbon-constrained future, the Indian renewable energy space is increasingly growing. The resource potential of India has also been recognised as substantially higher than earlier. Initiatives such as provision of solar parks, off-grid solar rooftop solutions and solar development in rural areas under KUSUM scheme can also help support rapid market development in India. India’s renewable energy growth is primarily propelled by a few driving factors such as considerations to meet energy demands, sustainability, energy security and lower costs.

WHAT DO YOU THINK ABOUT INDIA'S SOLAR POLICIES FROM A HOLISTIC PERSPECTIVE AND WHAT ACCORDING TO YOU ARE THE CURRENT BOTTLENECKS WHICH MAY IMPEDE GROWTH FOR THIS SECTOR? The Government of India has ambitious plans of generating 100 GW of solar energy capacity by 2022, but the momentum has been severely eroded in the last few months. Issues such as uncertainty around import duties and future tax rates on existing power purchase agreements have dampened investor sentiment. With the imposition of safeguard duty on solar cells, I believe it makes the situation all the more difficult. The safeguard duty will only be justified, and the country can achieve this target, if the domestic industry is able to match cheap imports within two years. We hope that soon the domestic industry will scale up and bring down the cost differential. The disruption caused by the COVID-19 crisis has posed further challenges to the industry.

SOLARQUARTER | APRIL ISSUE 2020

The recently announced draft Electricity Act (Amendment) Bill 2020 by the Ministry of Power to address structural issues and bring in fundamental reforms in the sector is a step in the right direction. Cost reflective tariff, simplification of tariff structure and reduction of cross subsidies is another positive move for the sector. The amendment proposes a contract enforcement authority for adjudicating in matters pertaining to contracts, except tariff related matters while the existing. In the proposed amendment, a payment security instrument is made mandatory for scheduling of power. While there is a clear attempt to address the fundamental issues, more clarity is needed in various aspects viz., jurisdictional clarity between regulatory commissions and contract enforcement authority, penalty payments for non fulfilment of RPO obligation, strict implementation of open access, distinction between distribution franchisee and distribution sub licensee, along with mandating payment security. We are confident that with stakeholder consultation, the draft bill will evolve, incorporating the necessary changes, especially as it is going to shape the future of electricity markets of the coming decade.

WHAT ARE YOUR GROWTH PLANS FOR THE INDIAN MARKET, AND DO YOU FEEL INDIA WOULD BE YOUR MOST FAVOURED DESTINATION FOR RE INVESTMENTS? In terms of our growth plans for the Indian market, our ambition and vision is clear. Along with our financial partners, we presently plan to execute around 250-300 MW of solar power capacity per year. We were initially bidding projects only in Solar park but our current ongoing 250 MW solar project in Rajasthan will be on Private land Consistency and clarity of regulation from the Government will play a vital role in paving the path for our growth in India. We are happy to be part of the Solar growth journey of the country and committed for future growth here. India is now part of Fortum’s home country of business and will continue to grow in Solar as well as in other businesses of Fortum in India. As declared earlier, we would invest between Euro 200 million and Euro 400 million in India in the solar power sector along with financial partners.

WHAT ACCORDING TO YOU IS THE BIGGEST STRENGTH OF YOUR COMPANY IN THE SOLAR INDUSTRY AND HOW DO YOU PLAN TO LEVERAGE THIS STRENGTH IN THE INDIAN SOLAR SECTOR? Fortum is a leading clean energy company that employs some 8,300 professionals in the Nordic and Baltic countries, Russia, Poland and India, and 57% of our electricity generation is CO2 free. The focus on reducing CO2 emissions has been in Fortum’s DNA for decades. Our carbon exposure is already one of the lowest within the European power generation industry. Fortum, being a utility company, always looks at every project from the long-term perspective. Quality is the key parameter always in focus while we design and construct the plant. During O & M also, we would like to use the natural resources in a very effective manner. This is one of the reasons that for all our solar plants, we are using waterless, Robotic technology so that the consumption of water for cleaning the panel is minimized and brought to almost Zero. Fortum’s 250 MW solar plant in Pavagada is one of the largest in India, having waterless technology. Going forward also, we planned to use the advanced module and inverter technology so that the plant can be built up with the minimum land area requirement. Fortum is happy to take the new challenges to showcase them in our upcoming plants.

The aim is to increase renewable capacity on the grid to 175GW by the end of 2022 and 450 GW by 2030.

PV panels improving in efficiency and cost-effective solar power combined with wind is now the cheapest electricity in the world.Solar PV installations are now being installed for a variety of applications on a largescale to provide electricity on a commercial scale as well as mini-grids and personal use. Using solar PV to power mini-grids is a superlative way to bring power access where power transmission lines are far-reaching. Solar panels have a lifespan of around 30 years and it comes in a variety of shades depending on the type of material used in manufacturing.

The most common problem witnessed in solar installations is improper solar module racking. If the mounting system is not fixed properly so as to keep the solar panels in place, it could make the panels more vulnerable to damage. All solar panels should be in track with each other or it will have a bearing on their efficiency as well. Solar installations will also be prone to malfunctioning if the panels are not sufficiently anchored or if all the bolts are not tightened securely. Besides, insufficient insulation and poor wiring can increase the risk of fire. Faulty wiring, along with loose connections and associated factors like corrosion and oxidation, affects the

PROTECTING THE SOLAR ENERGY INDUSTRY IN INDIA DURING A PANDEMIC OUTBREAK

IMPACT OF COVID-19 ON THE SOLAR ENERGY INDUSTRY IN INDIA Solar power is a fast-developing industry in India. As of end February this year, the country' s solar i nstalled capaci ty reached 34. 404 GW. Indi a has set an ambitious target of installing 100 GW solar energy capacity by 2022. The ongoing COVID-19 pandemic has heavily affected the industry, impacting solar power proj ects i n vari ous aspects. These i nclude:

GLOBAL SUPPLY CHAIN The most significant near-term impacts on renewable plants that are already contracted or under construction may be felt through supply chains. While China, which is India’ s main supplier of PV panels, is limping back to normalcy, the road is very arduous and time-taking. There will be delays in projects and provisions around cessation of work that need to be incorporated in on-going projects. Chinese firms supply about 80% of solar cells and modules, which form up to 60% cost of a total project, to India.

POWER DEMAND

The electricity demand in India dropped from 163. 73 GW on 20 March to 127. 96 GW on 25 March when the country started its lockdown. As the government extends the lockdown to contain the coronavirus outbreak further, it is expected that there could be business losses. Unfortunately, these losses will have to be absorbed by companies in the absence of a pandemic insurance cover (which is excluded in almost all Indian insurance policies).

DELAY IN PROJECT The lockdown on all non-essential businesses, which cover solar construction projects has resulted in projects delay. Material needed are stuck on roads. These will lead to delay in the commercial operation date. While the project insurance policies exclude pandemics, this could become a new request from the Independent Power Producers (IPPs).

SOLARQUARTER | APRIL ISSUE 2020

LABOUR SHORTAGE

Even as some relaxations in the lockdown and restart of some economic activities are expected, project developers continue to be wary and cautious of the labour shortage. Workmen who have gone back to their homes across the country are not expected to return soon. Most solar projects are in villages and local authorities may be reluctant to allow the migrant workers to travel out. The bigger concern is the roof-top projects in factories and plants where commissioning will be slowed over the next few quarters.

MITIGATING THE RISK

Project delays on the solar construction projects can significantly impact India’ s flagship target to generate 100GW of solar energy by 2022. To mitigate this impact and risks from the COVID-19 outbreak, various actions are undertaken to support India’ s solar energy industry. As of end March, the Indian government has allowed solar energy companies to cite force majeure clause over coronavirus disruption. This move could be a relief to project developers as otherwise they would face fines through no fault of their own.

To overcome this challenge, a unique risk t r a n s f e r s o l u t i o n , c a l l e d e p i d e mi c r i s k transfer solution, is recently developed. Unlike traditional insurance, this solution does not take property damage as the trigger of insurance indemnity.

WILL IT HAPPEN AGAIN? Experts with diverse backgrounds all over the world are working towards faster development of vaccines against COVID-19, including six Indian companies. Nevertheless, epidemics of infectious diseases are occurring more often, and spreading faster and further than ever, in many different regions of the world according to the World Health Organisation (WHO). The background factors of this threat are biological, environmental and lifestyle changes, among others. Although the healthcare and response system may improve after pandemic crisis, in terms of testing, reporting, communication intervention, epidemic should be included as one of the major risks solar energy industry needs to seriously consider and factor companies’ business continuity plan in the future.

Alternative risk transfer solutions for solar energy companies

Normally, the conventional insurance programme does not cover loss of revenue due to insufficient labour or suppliers’ shutdowns. To trigger the business interruption coverage, property damage is a pre-condition for that to happen. To overcome this challenge, a unique risk transfer solution, called epidemic risk transfer solution, is recently developed. Unlike traditional insurance, this solution does not take property damage as the trigger of insurance indemnity. Instead, it pays a claim based on the severity of an epidemic outbreak. This provides an effective risk transfer for solar energy companies. It can help to cover some extra cost that may be incurred, for example workers’ quarantine cost and worksite cleaning cost, as well as the loss of revenue due to the delay in start-up because of an epidemic and/or pandemic outbreak of known or unknown origin. The solution can be tailor made depending on the project size, construction period and company’ s budget. It can be offered as either a parametric or indemnity-based policy. The capital market could also be another solution provider. A very wellknown insurance-linked securities (ILS) related to epidemic outbreak is the pandemic catastrophe bonds sponsored by the Pandemic Emergency Financing Facility (PEF) established by the World Bank. The mechanism of the pandemic catastrophe bond is similar with the traditional catastrophe bond. If there is a pandemic outbreak in the world before the maturity of the bond and payout triggers are met, the bond issuer will not return the principal and interest to the bondholder. The bond principal amount will then be converted into an anti-epidemic fund. If the triggers are not met, the bond issuer will return the principal and interest amount to the investor as agreed. The interest rate of the pandemic catastrophe bond is higher than that of other bonds in the market. Protecting the solar energy industry in India

It would still take months or longer for us to know the full economic impact from the COVID-19 crisis. However, we have already seen its massive impact on solar energy industry in India. The government, India solar energy industry and global community are taking constructive and preventive measures to mitigate the losses and risks, especially in the post-pandemic recovery phase, ensuring that India stays on its path to pursue clean energy. Going forward, there are unique risk transfer solutions available to protect the investment interest of the industry. It is impossible to predict when the next ‘ black swan’ event can happen and impact the industry. Being ready for the unknown risk can always save vulnerable entities in difficult times while waiting for the light at the end of the tunnel to come.

HOW CAN GUJARAT MAINTAIN IT'S LEADERSHIP POSITION IN SOLAR ROOFTOP SEGMENT?

Artha Energy Resources.

Sunfraa Renewables LLP

Gujarat is amongst the top 3 most industrialized states in the country with a total installed roof-top capacity of 264MW. This capacity puts Gujarat as the state with the fifth-highest installation after Maharashtra, Karnataka, Tamil Nadu, and Rajasthan. Being the first state in the country to adopt netmetering, Gujarat has been the thought leader for the renewable energy industry. Despite its progressive approach and thought leadership, Gujarat lags other states in terms of the Solar Roof-top Segment. The Hon. Minister of Power, Mr. RK Singh, revealed in the Parliament that Gujarat has the highest roof-top installations in the country with 264MW. There were 50, 915 subsidized solar plants installed in the state against 79, 950 for the country. It represents a market share of 63%, which is an impressive achievement. Furthermore, the Gujarat government recently announced a scheme to install 600MW across 2 lakh households in the state and provided a budget of Rs 1000 crore for the same. It will further cement the leadership of the state in the residential roof-top segment. Subsidy of 20-40 percent is available depending on the size of the system. Excess power would be sold to the DISCOM at Rs 2. 25 per unit (Kwh). A benchmark installation price will be identified through a bidding process. The state had previously empaneled 450 firms from which consumers could choose for installation and is repeating the same procedure. All the above measures will ensure Gujarat will retain its leadership position in the residential roof-top segment. However, there is a longstanding demand for installers to have the subsidy released from the government on time. In many instances, the subsidies delayed by a few months, which increases the working capital stress for the installers. Apart from this, we believe Gujarat is doing a fantastic job, and continued support of the administration in ensuring timely sanctions, net-metering approvals, and faster subsidy release will ensure Gujarat maintains its lead in the segment. Lastly, an important fact being missed by all is that Gujarat is not the state with the highest roof-top installation in the country. It is due to poor penetration in the commercial and industrial sectors. Maharashtra has seen impressive growth in the roof-top segment due to higher power tariffs and, most importantly, the ability to install roof-top projects on the third-party ownership model. Currently, OPEX (third-party ownership) model is not allowed in Gujarat. Should the state re-look at allowing this model, it will ensure Gujarat on the fast track towards a pole position in the Solar Rooftop segment.

SOLARQUARTER | APRIL ISSUE 2020

Gujarat has always been a pioneer for solar energy since the inception of the Solar Power Policy 2015. There has been no looking back since then. As per the data by MNRE 2/3rd of the total rooftop installations of India are in Gujarat. People of Gujarat are prone to adapt new technologies as per the need of the hour compared to any other state. Having said that, the leadership of Gujarat in adopting solar energy has inspired other states to follow the same route and there has been a healthy competition which I see as a catalyst to achieve the 100 GW target. The fulfillment of recent tender of 600 MW rooftop for residential within 5 months is the biggest proof of Gujaratâ&#x20AC;&#x2122; s leadership in the segment. Measures taken by the government construction bodies like AUDA, GUDA etc. for mandatory installation of solar rooftop system in any new construction for BU permission shows the commitment of the Gujarat govt. to lead the segment. Also, Solar Rooftop system is the only entity which gives the beneficiary more than 20% annual return on investment and hence the business community of Gujarat needs no better reason than this to lead the path.

With the vision of Charanka, Solar Park, Gujarat had taken leadership in ground mounted solar projects. Gujarat is one of the most rapidly developing states in the country for renewable projects. Of late, the state has developed Rooftop Policy & the state has rapidly emerged number of Solar Rooftop Installation in residential segment like any other state of India. Aggregate 1. 1 Lakh+ Installation registered so far as per the confirmation by GUVNL and over all applications for 450+ MW capacity till February, 2020. To Maintain its leadership, followings are the key sectors where implementation on Policy required : Recent Policy Update for the SME Sector has not received much impact due to 15 Minutes Logging Interval & 1. 75 Rs. / Unit rate for the purchase of power. The growth of the SME Sector in Gujarat is very important. Hence for new Industrial Development, implemented Solar Policy for the same required with proper incentives. Revised policy for Residential Project required. Government had already declared incentives on the achievement of installing additional grid-connected rooftop capacity in all sectors over and above the base level, with the incentives being limited to the first additional 18 GW of rooftop capacity added in India. GoG Discoms to take maximum benefits of this Scheme. MNRE has announced a scheme that aims at 100 per cent Solarization of Village Modhera in Gujarat. Under the scheme the domestic and agricultural electricity needs of all the households of Modhera are planned to be fulfilled with solar energy. Gujarat can take leadership for adding more villages as per Modhera Model. As per visionary approach with correct policy the stateâ&#x20AC;&#x2122; s rise in promoting solar rooftop installations is a testament to the government. And with above Gujarat will become leader of residential solar rooftop systems in India.

Gujarat has emerged as a market leader in the Solar Rooftop segment in the country. As of Mar 2020, Gujarat state is leading the rooftop installations as it has installed approx 60% of total solar projects installed across the country. Gujarat state government has adopted the Surya- Gujarat rooftop scheme for 600 MW residential solar projects. Under this scheme quality of challenges were overcome by the empanelled agencies and more than 1 lakh applications were received. Of the 600 MW offer to bid, the state has registered applications for 490 MW capacity as of February 29, 2020. As the scheme remains unsubscribed for 110 MW, new tender has been facilitated by the Gujarat govt. to augment the use of solar energy in the state. This tender initiated by the Gujarat govt can surely be a welcome move as the customers are very well aware of solar energy benefits and consciously taking decision to switch towards clean energy. Incorporating Direct Benefit Transfer (DBT) policy could give Gujarat a competitive edge from other states in terms of state attractiveness of installing rooftop solar. DBT mechanism allows state to transfer direct subsidies to the beneficiary through their bank accounts, considerably reducing the financial risk involved for the solar developer and definitely create a win-win situation for consumer as well as developer. GEDA registration charges of Rs. 11, 800 is levied on commercial industrial customers irrespective of their plant capacity. This hefty cost demotivate small factory owners from installing solar plants. In suggestion charges fixed should be reasonable and based on registered solar capacity.

In Gujarat State, commercial and industrial customers are allowed to installed solar rooftops only 50% of sanctioned load. This implies that companies are required to arrange upfront capital for the rooftops which would cater to only part loads and are unable to realize complete savings. On top of that the plant load factor (PLF) of solar is around 17-18% which again affects the commercial viability of the project. For rooftop solar to completely take off in Gujarat, relaxation on sanctioned load should be given to resolve difficulties faced by people in optimum utilization of solar plants. Further, RESCO model has gained traction in different parts of the country. This has largely solved the challenge associated towards the upfront capital cost. Currently, Government of Gujarat only allows the CAPEX model and is yet to take a call on pushing the RESCO model in the State. Many small and medium scale industries are reluctant to invest upfront capital for rooftop Solar and also face challenges in raising financial capital for the same owing to their poor credit rating. Promoting RESCO model in Gujarat can see a rise in demand for Solar Rooftops for the Industrial & Commercial segment. Another challenge that the commercial and residential segment faces for installing of rooftop is space availability. Due to limited space and a common terrace in many multi-story buildings, individual unit owners/ residents are incapable of installing rooftops. This challenge can be addressed if the Government of Gujarat can initiate a scheme to set up small ground mounted solar parks of 5 to 10 MW where a pool of interested commercial/ residential owners can buy their specified quantum. This would not only ensure better solar generation but also solve the space constraint. Shifting this to the RESCO route would solve all the constraints of space and capital.

Gujarat has introduced the Solar Policy in September 2015 with the objective to promote green power and reduce the carbon emission in the state. In the “Gujarat Solar Policy 2015” total of approximately 500 MWp of rooftop installation is done with approximately 200 MWp of installation in Industrial and Commercial Rooftops while approximately 300 MWp of installation in Residential Rooftops. Gujarat presently is one of the leader in the Solar Rooftop Installation in the country. All the stakeholders GEDA, DISCOMS, GETCO, GUVNL, CEIG Office has designed an efficient policy and approval system for the Solar Rooftop Installation. To continue to be one of the leader in Solar Rooftop Installation in the country following are the recommendations: Present Policy:

A. Non MSME Industrial a) Maximum Plant Size: 50% of the sanctioned load in KW for the non MSME industry consumer b) Net Metering: Net Metering is allowed for plant size of less than 1 MWp Units settlement in the same month of billing No RPO or REC benefit can be taken by Industry Consumer c) Without Metering: With RPO Benefit taken by Industry Consumer: Excess units will be set off in the same month of billing at APPC Rates With REC Benefit taken by Industry Consumer: Excess units will be set off in the same month of billing at 85% of APPC Rates. d) Electricity Duty: Electricity Duty is exempted on Solar B. MSME Industrial a) Maximum Plant Size: More than 100% of the sanctioned load in KW for the MSME industry consumer b) Net Metering: Unit settlement will be done every 15 minutes c) Electricity Duty: Electricity Duty is not exempted on Solar C. Residential a) Maximum Plant Size: More than 100% of the sanctioned load in KW b) Net Metering: Net Metering is allowed c) Electricity Duty: Electricity Duty is exempted on Solar

Improvement in Rooftop Policy: Maximum plant size allowed can be increased to atleast 80% of the sanctioned load in KW. This will motivate the consumers to put the additional solar rooftop system. Electricity duty benefit is recommended be continued as per the exiting policy Excess units settlement is recommended to be done in the financial year instead of the same month It is recommended that Solar Rooftop installation on the OPEX (Pay per use) model should be allowed. It is recommended that MSME consumer should be allowed with the benefit of the Electricity Duty It is recommended that Transmission Charge, Transmission Loss, Wheeling Charge, Wheeling Loss, Cross Subsidy Surcharge, Additional Surcharge exemption should be continued as per the existing policy.

The state of Gujarat has so far been a pioneer in the rooftop solar segment. Taking the above new ideas and schemes into consideration it can not only maintain its leadership in solar rooftop segment in the country but also create a benchmark that serve as a guide to other states. By taking path breaking efforts it will bolster stakeholder’ s confidence and definitely help in achieving India’ s 2022 target.

The solar sector is progressing and has evolved rapidly. Solar power in India is a fast developing industry. The country's solar installed capacity reached 34.404 GW as of 29 February 2020. Talking about consumption, a new demand segment for solar power is picking up the trend i.e. solar rooftops. Photovoltaic systems are generally categorized into three

segments:

residential

rooftop, commercial rooftop, and ground-mount utility-scale systems and their capacities range from a few kilowatts to hundreds of megawatts. As of July 2019 by far the second largest segment of solar PV installed in India was rooftop solar at 2,141 MW which can be divided into residential solar, commercial, and industrial solar roofs as well as a range

According to the Government data, as of mid-March 2020, the total Rooftop Solar (RTS) installation in the country was 1, 922 MW, of which 346 MW have been installed in the residential sector or around a fifth of the total. If we look at the big numbers of the Renewable energy (RE) capacity target of 175 GW we hope to achieve by 2022, 40 GW is expected from rooftop solar (out of the 100 GW from solar as a standalone category within RE). As recently as January this year, the Parliamentary standing committee on energy has said that the 40 GW target is unrealistic. Further, given the current global situation due to the COVID-19 pandemic and the fact that 80% of the hardware components for solar power come from China, it will be unreasonable to expect any major boost to the growth in the rooftop segment, particularly the residential sector. From a mid to long term perspective, RTS is a great investment for consumers, but it is still not a high priority area. For utilities, including the EPCs that support them, the current priority is to ensure that we do everything within our capacity to ensure the essential energy needs of the country are met with little or no disruption. We will have to take stock once the nationwide lockdown is lifted and the economy gets back to normalcy.

that for the next three years, rooftop solar installs will grow at a CAGR of 50% suggesting a cumulative 13 GW of installed capacity by FY2021-22. Various studies show that the residential rooftop solar sector is growing steadily to know more about this, we spoke to several Indian business leaders for their insights on growth of residential rooftop solar sector in India.

SOLARQUARTER | APRIL ISSUE 2020

The time for the growth of residential solar was right just before March as many state governments have introduced schemes and subsidies for the acceleration of the market for the coming year 2020-2021. The unforeseen circumstances have changed this and now it depends on how the economy recovers - if there is some growth path in a couple of months the market might be open, it also depends on the government' s reaction towards releasing subsidies once lockdown is lifted. A lot of things have been affected by the Covid-19 lockdown; due to the slowdown of the economy, there may be some downturn in the growth of the residential solar market immediately. However, depending on how the next few months proceed and each state government' s reaction towards keeping subsidies ongoing or pausing subsidy delivery - the opportunity for the growth of the residential solar market can still be tapped in 2020.

The Solar Rooftop capacity in Indiaâ&#x20AC;&#x2122; s solar target of 100 GW by 2022 has been put at 40 GW. This Rooftop Solar target was initially met with a lot of pessimism but the capacity additions picked up pace and now finally it started showing a healthy growth. This has been possible mainly due to Solar rooftop tariff achieving grid parity for residential as well as rising corporate and industrial (C&I) market even without government subsidies. The Solar Rooftop capacity of India will touch 6. 5 GW growing at a CAGR of more than 50 percent. Considering similar growth in the next three years it is expected that it will comfortably reach 16-17 GW by 2022 end. However, still it will not be able to meet the target of 40 GW.

In 2019, 7. 3 MW of solar power plants were added in India. Out of which, 1104 MW came from rooftop solar power plants. The rooftop solar power plants capacity addition decreased by 33% YoY. Multiple reasons are being cited for this decline such as election year, economic slowdown, govt policy flip flops etc. 2020 didnâ&#x20AC;&#x2122; t start on a positive note either. With the coronavirus pandemic bringing the economy to a halt, the near future is not looking very strong for solar power plant projects in general and rooftop solar power plant projects in particular. Financing rooftop solar power plants has always been a bone of contention for consumers. As this pandemic will be followed by a liquidity crunch in the market, the stalled projects will take time to restart and new projects will be harder to come by.

Within the Rooftop Solar market C&I segment have led the growth till now capturing more than 80 percent of the market while the residential segment has been lagging at around 10 percent. The main reason for early adoption of rooftop solar and high growth by the C & I segment was higher grid tariff differential and thus achieving grid parity quite early. In India the residential and agricultural consumers enjoy a subsidized tariff which is compensated by making the tariff higher for the C&I segment. The residential consumers were initially attracted towards the subsidies provided for rooftop solar but later due to the painful claim process subsidies died out and they started going for solar without any subsidies. Lowering of solar system costs and aggressive marketing by many rooftop EPC players have been the reason for increase in rooftop solar installations among the residential sector in recent past which is a free market now. Such a market is now creating thousands of entrepreneurs eager to find a way to differentiate their offerings and respond faster to market needs with innovation.

The policy paralysis of the government regarding the subsidy of the solar power plants is creating an atmosphere of uncertainty. The consumers are also stalling the projects until there is a clear policy on grid support charges from the government.

As per MNRE a Rooftop solar system will make a good business proposition for any residential consumer whose monthly bill is more than INR 8000. The amount invested in such a solar system is recovered within 5 years whereas the system life is 25 years. The cost economics will be the dominant reason for the rise of residential consumers based in a price sensitive Indian mindset.

The continued growth of the rooftop solar plant sector will depend on a variety of factors such as ease of net metering procedure, clarity on the subsidy policy, quick disbursal of pending subsidy and availability of easy financing for solar power plants.

The supply chain is also going to take a severe hit because of the pandemic. The prices of the solar modules are going to rise in the immediate future until the production lines and supply chains in China come back to their full potential. The increase in rates of the solar power plant, in addition to the liquidity crunch in the market and policy flip flops, will result in further slowdown in the YoY growth of the rooftop solar plant installation in 2020. With the declining rate of growth, it is clear the target of achieving 40 GW through rooftop solar power plants will be missed by a huge margin. Until December 2019, only 4. 4 GW of rooftop solar power plants have been installed.

The residential rooftop market will not only maintain its existing momentum of growth but will find ways to surpass it due to many reasons. The improvement in the module efficiencies over the last 10-11 years have been significant in ensuring that the solar power generated per square meter keeps improving. Solar module manufacturing companies have come a long way today with 400 Wp becoming the new normal now. This is a direct four times jump on the roof area use efficiency in 10 years. With commercially viable bifacial technologies around the corner, this number will jump to 500 Wp within one to two years. A higher Wp per Square meter has an added advantage of reduced Balance of System (BoS) costs, which will push the industry and will help to grow the market. This year we are likely to see an increasing number of projects utilizing PERC cells as the supply ramps up and the prices slide consequently. It is expected that shift to mono-PERC modules will be rapid as they are more efficient and can help reduce roof area and other BoS costs for consumers, leading to shorter period in return of investment. The next revolution of the storage segment will also help in pushing the momentum of growth for distributed generation. Storage will change the way people depend on the grid for their everyday power needs. Energy independence will become a new norm. It is due to this result that even common people are also acknowledging rooftop solar power. EVs starting from two wheelers are going to enter Indian market this year. Electrical energy will be the new fuel and a rural India with large roof space is expected to grow the market like never before. COVID-19 pandemic is taking the residential consumers' realism towards becoming independent energy generators to save their households from power shortages in such situations. This will be a great marketing point coupled with power for consumption of EVs which can drive the unorganized rooftop solar sector to a new height.

TECHNOLOGICAL CREATIVITY AND QUALITY Powerline Communications Capabilities The 110kW inverter communication supports optional PLC. This means an additional communication cable is not required, which saves both time and money for installers. Reduced Self-Generated Errors Large PV systems are built with numerous panels, and each panel has its own set of unique characteristics. As a result, working with different panel manufacturers increases the risks of errors. Solis created a unique leakage current suppression technology through long-term PV power station data collection and technology development. This technology not only suppresses the impact of the PV system leakage current, it also reduces the number of erroneous errors, or “false alarms”, and significantly improves the stability of PV systems. Reduced Effects of Inverter Output Resonance Solis uses the "intelligent reconstruction" algorithm technology, which reduces the effect of high capacitive or inductive hardware to achieve a large-capacity square matrix resonance suppression function. Our advanced anti-resonance technology helps to increase more accurate readings and reduce inter-plant inverter interface, reducing downtime and increasing yield.

The initial steps towards cost-effective ways to speed up the installation of solar systems is choosing the best quality products with latest technologies like Bifacial, Mono PERC etc. and also an efficient workforce. Use of Drone technologies will bring the added advantage. For long term success of the project we need to design the project from a water availability perspective also. It will be good to have a waterless cleaning system to solve the lifelong water problem at the site. It is imperative to have all the settings and pre- assemble plans worked out as much as possible before arriving on site. As the current use cases of solar and solar storage become more convoluted, it is of utmost importance to lay emphasis on the role of teamwork and communication within the crew members. Also, the use of modern design software in both the design storage and operation of the systems has become much more important than ever. This further helps in creating a virtual twin of the system, simulates a year (or more) of operation, and allows iterations of variables to zero-in on an improved system leading to better efficiency and control.

Following are the few ways to speed up solar installation of solar system:

Standardization Design of Module Mounting Structure (MMS) MMS majorly comprise of columns, rafter & purlin. To become competitive EPCâ&#x20AC;&#x2122; s currently design and manufacture components of various shapes and sizes, which eventually converts into different numbers at component level. Like purlins of different sizes are used for same row which in turn increases the process of segregation, storage, and installation. Also, it increases the probability of mismatched installation leading to rework at site. Keeping in view if the components are standardized for the complete MMS, it will help in many fronts like appointing multiple manufacturers, fast production, easy logistics, minimal segregation at site and thus faster installation.

Optimized and Standardized Block Size Engineering team should implement best design practice to optimize & standardize solar block size, which will be helpful to speed up ordering process of major equipment. This entire process is useful to ensure sequential material supply chain as per the installation process and speed up solar module installation at site.

Utilization of robotic system at site helps faster module installation & other repeated work packages

SOLAR AFTER THE BLACK SWAN

Wikipedia defines a Black Swan event as a metaphor that describes a happening that comes as a surprise, has a major global impact, and is often inappropriately rationalized after the occurence. The phrase "black swan" gained currency a decade ago during the Great Recession after 2008 financial crisis. It was coined by a mathematician & economist named Nassim Nicholas Taleb. The Corona virus, is a perfect fit for Taleb' s definition. The extreme worldwide impact, in terms of human lives, dislocation, and economic losses at this point of time cannot even be imagined, forget estimated. “Was the emergence of such a dangerous virus really unpredictable ?" A whole host of Hollywood movies like World War Z, 28 Days Later and almost the blueprint of COVID-19, Contagion have all the time pointed at the bio-bomb mankind was sitting on. Nonetheless, the impact of such viral outbreak was certainly unprecedented and unimagined. Black Swan or not, the COVID-19 event will also have a profound impact on the Indian Solar industry. Firstly, let’ s look at the electricity generation and transmission industry of India in the recent past. Our PM Modi’ s ambition to electrify every village in the country has led to surging demand for grid power. Published data shows that over the five years through 2018, India added output both renewable as well as nonrenewable, equivalent to 50 small nuclear power stations. This booming market hasn’ t translated into good times for the industry. Less than 5% of these large electricity Companies are barely covering their costs (Bloomberg). The problem has seeds in the success of masselectrification campaigns like Modi’ s. While he drove the march to power outreach to every corner of the country, the distribution networks that are owned by state governments are run more with political objectives than commercial profits. Cheap electricity is a clear vote-winner. Thanks to regulated prices and the general mismanagement of the network, India’ s distribution companies (Discoms) lose around Rs. 0. 35 plus on every watthour of electricity they deliver. Topping that with transmission losses and theft, their independent survival looks impossible. With the advent of COVID-19 event Discoms are permitted to extend settlement of their dues to power generators by 3 months and that itself will weigh heavily on the bottomlines of all power generators including RESCOs. Most of these will see their mountain of debt rising to prohibitive extents and thus impacting credit ratings. RESCOs will find more and more difficult to offer packages against these depleted Credit ratings. Most large Solar Companies in the country are staring at this grey-dyed future. Cut back to mid-sized Solar equipment Companies and EPCs. The enduser client of such Companies is India’ s industry, corporates and entrepreneurs. It will require zilst Rocket Science to understand that most Corporate balance sheets this year will be stretched. Room for capital asset procurement will be squeezed to say the least. And then amongst the basket of capital assets for any manufacturing industry, Solar system might not figure on the top.

SOLARQUARTER | APRIL ISSUE 2020

For Solar system component manufacturers, let us divide these into 3 groups : 1) Cell & Module manufacturers , 2) Inverter manufacturers and 3) BOS manufacturers. A major chunk of raw material of Cell & Module manufacturers was imported and mainly from China and the Far-East. With overseas air and sea movement blocked / restricted, this channel will take some time to reach it’ s earlier efficiency levels. Local manufacturers of similar items have a splendid opportunity if they are able to deliver quality. Next are the Inverter manufacturers. Almost entire ongrid requirement of Solar inverters in India is imported, leave a bit and hence immediate shortage is impending. Also how much import from China will be permitted by the Government will decide the availability of such equipment. Indian manufacturers of Ongrid inverters have not been able to deliver reliable products at competitive prices, though the technology is available. This is their big opportunity ! Offgrid inverter manufacturers in the country are already having a good chunk of the pie having mastered indigenousization. They are the least affected barring few imported components. The third subset are the BOS component manufacturers including the structure, cable and minor items. All these are least affected since their import component was minimal. Hence we could deduce that in the medium term cost of a Solar Plants will slightly inflate with major components, panels and inverters heading for short supply. But this will also be offset by low industrial demand envisaged in this financial year. The EPC guys will have to take a shave to survive the low-tide. Next is the bunch of medium-small EPC contractors. They will do themselves a world of good by focusing on Government residential Schemes, water pumping Schemes as well as Solar Homelighting. Survival of the fittest will be the mantra. The Government on it’ s part can offer 2-pronged assistance to the industry. One is obviously step on the pedal of Solar Schemes and disbursements especially residential / homelighting and minigrids. Secondly, it can create an additional push for the Solar industry without directly investing, by increasing the depreciation rate of Solar Systems for Corporates, thus improving their ROI on Solar investments. Many Companies including PV Power Technologies have written to the Commerce Ministry as well as Finance Ministry with the upcoming woes of Solar industry and hope to see some positive action.

THE

SHIFT

The first part of the article “The transition from Lead Acid battery to Lithium Ion battery: Why is the shift necessary?” introduced the need of storage and further detailed about the lead acid battery. It also discussed major disadvantages which were associated with the lead acid battery. This part of the article shall educate its readers about Lithium Ion battery, its working and its advantages over lead acid battery. Further it shall also detail the market dynamics of Lithium ion battery and its applicability in the Indian sub-continent. While considered to be one of the most emerging technologies in the storage industry, lithium ion is just 50 years old. Similar to most of the battery technologies, the lithium ion battery has cathode, anode, electrolyte and a separator. The cathode of the battery is usually made up of combination of lithium & oxygen (known as the “active material”), a conductive additive and a binder. The anode of the battery is usually made up of graphite which is known for good structural stability, low electrochemical reactivity, better affinity to lithium ions and lower price. The most common electrolyte used in the battery is a lithium salt, such as LiPF6 in an organic solution. The separator in the battery is usually made up of polyolefin as it has excellent mechanical properties, good chemical stability and lower costs.

WHY

However these batteries had higher thermal runaway, meaning that there was a fair chance that the battery possessed risk of exploding if it were damaged or overcharged. This directly led to compromised safety and life span of the battery. Lithium Iron Phosphate (LFP): Discovered in 1996, LFP batteries offered good electrochemical performance with reduced resistance, excellent safety and long life span but moderate specific energy and a lower voltage than other lithium-based batteries. Its excellent thermal stability and enhanced safety enabled it to be utilized in applications which needed higher load currents and endurance, for ex: EVs, solar PV plants, UPS. Lithium Nickel Manganese Cobalt Oxide (NMC): One of the most balanced performing lithium ion batteries is NMC. The cathode combination ratio which is usually one-third nickel, one-third manganese and one-third cobalt means that the raw material cost is lower than other types of batteries. Such combination further also allows NMC battery to be either utilized as a high energy battery or a high power battery. The battery found its application in EVs, medical devices, industrial applications, etc.

Figure 2: Comparison of various lithium battery technologies (Source: Battery University) Let us now understand the advantages of Lithium ion battery over lead acid battery:

Figure 1: A typical Lithium Ion battery (Source: Samsung SDI)

Light weight and easily portable: The lower weight of the lithium ion battery (compared to other commercial battery technologies) is probably one of its primary advantages. This is primarily because the battery utilizes lithium as its main components, which has both lower density and highest electrochemical potential. This further means that the battery has both higher energy density (3~4 times higher) and power density (3~6 times higher) which makes the battery even lighter when compared to lead acid battery. Additionally with the lithium battery utilizing dry electrolyte & electrodes, its installation and transportation becomes stress-free.

The Li-ion battery works on the principle of electron-ion exchange, similar to most of the batteries. During discharging, the electrode with the high electron affinity will release electron (which is known as anode) and the electrode with the low electron affinity will gain electron (which is known as cathode). This electron would travel through the load and thus allowing the battery to supply energy. Each component however has a specific function to perform. Cathode primarily determines the battery capacity i. e. higher the amount of lithium at cathode, the higher is the battery’ s capacity. The anode enables exchange of lithium ion from/to cathode while charging/discharging. The electrolyte is one of the most important components of the battery. The salt present in the electrolyte allow only the passage of lithium ions and thus forcing the electron to be move via the external circuitry only thereby supplying the required energy to external load. The separator further facilitates such movement of lithium ion through its internal microscopic hole while also forming a physical barrier between the electrodes.

Shorter charging times and high energy delivery rates: With the application of storage now diversifying to in EVs, power plants, micro grids, etc. where the end application calls for the devices to be charged quickly and deliver high energy in a short span of time, lithium ion seems to be the perfect match. Compared to lead acid battery, the charging time of lithium ion battery could be reduced by 60% which makes it suitable for such applications.

Let us now understand the (few important) existing battery technologies of lithium ion:

Better performance in extreme climates: Considering a case of India where extreme ambient temperatures are normal, a battery is required to be operational in all such conditions. Comparing both the battery types, the available capacity of lithium ion battery is better compared to lead acid battery (refer Figure 4) at both the extreme temperatures. This directly points out that lithium ion battery could be utilized at much better levels at all the temperature ranges.

Lithium-Cobalt-Oxide (LCO): One of the earliest commercialized chemistry (in 1985) for Lithium ion batteries were the LCO batteries. These batteries had high stable energy capacities which allowed them to be utilized in applications in laptop, mobile phones, etc.

SOLARQUARTER | MARCH ISSUE 2020 SOLARQUARTER | APRIL ISSUE 2020

Higher cycle life: One of the major concerns for storage is the duration up-till when it could be used. A battery is known to be rendered useless if its capacity reaches to 80% of its rated capacity. A typical lead acid battery runs for 300~500 cycles which means that it need to be replaced between every 1~2 years. A lithium ion battery on the other hand runs between 1, 500 to 2, 500 cycles which is almost 5 times more than the lead acid battery.

TECH TRENDS

This part of the article shall educate its readers about Lithium Ion battery, its working and its advantages over lead acid battery.

Figure 3: Capacity Available versus Temperature (Source: ALLCELL) The above factors make it clear that the Lithium Ion battery (and its variants) have a clear potential of covering almost all the applications which utilizes lead acid battery. The battery technology which has started seeing the light of the day is expected to have an exponential uptake, thanks to few specific applications like EVs, energy storage, consumer electronics, E bikes, etc. EVs are already creating a buzz in the automobile sector primarily due to the ill effects of traditional fossil based vehicle. The lithium-ion battery demand for EVs is known to grow from around 200 GWh in 2020 to 1, 748 GWh annually by 2030, showing a rise of 900%. Such rise is primarily known to fuel the growth of the battery technology is the next decade. Further with the increased electrification around the world, the need for 24x7 reliable supply of electricity is increasing. With the lifetime limitations of lead acid battery, it is much expected that the grid managers and the generators shift towards lithium battery. It is almost known that no technical breakthrough can make it to the market if it is not cost effective and the same is true for lithium ion as well. The costs of the battery in 2019 have reduced drastically to around 83% when compared to that in 2010. This cost is further expected to reduce by 65% and stay at around 60 $/kWh by 2030. Such price drop would further fuel the growth and adoption of lithium ion battery. Talking about the Indian scenario, the country has announced bold plans to adopt and integrate (directly and/or indirectly) storage or more appropriately lithium ion batteries in its energy mix. The National Electric Mobility Mission Plan (NEMMP) aims that the country starts manufacturing, adopting and utilizing electric vehicles. It is further also believed that all the vehicles sold after 2030 shall be electric in nature. The National Energy Storage Mission (NESM) adds on and supports the NEMMP in the country. It aims that to set up the entire supply chain for lithium ion battery thereby capturing the market opportunity between INR 2, 000 to 3, 000 billion. While the above two plans are still on papers, the scheduling and forecasting regulation (already passed in various states) for solar PV plants directs them to provide a forecast of their generation. A regulation like such demands the power plants to be equipped with adequate storage to ensure that they maintain steady and declared energy output.

We at Waaree Energies keep close look at the market trends and in order to facilitate the shift which Indian storage market is undergoing, we have started a new lithium ion battery manufacturing plant. Capable of producing battery packs of both NMC & LFP technology, our batteries could be used specifically for EVs, power backup at grid level/power plant level, solar street lights, etc. These batteries are tested in accordance with all the national and international standards ensuring that the end customers get more than desired returns on their projects.

MINIMIZING

THE

IMPACT

COVID-19: SUNGROW, MANAGED

Sungrow, headquartered in Hefei, China, is one of the leading suppliers of solar inverters and battery energy storage systems in the world. The company’ s manufacturing capacity got affected by the impact of COVID19 in early Feb, 2020. This was the time when the Chinese New Year holiday was extended to contain the spread of the virus. Further, as a safety measure, people who returned from holiday travel were mandated to be in self-quarantine for 14 days before joining to their workplaces. Since maximum of Chinese people travel to their hometowns during this period, many Sungrow employees also travelled during this Annual holiday for the celebration. As many factory personnel returned from hometown after the extended holiday, they also stayed in the self-quarantine as per the issued advisory. This initially had a short-term impact in the factory. The employees from other departments could work from home unlike the workshop which needed manpower at shop floor. As a tactical response to the newly developed challenging situation, Sungrow hired and trained hundreds of workers on temporary basis to get the manufacturing jobs that didn’ t require much technical know-how or expertise. Although Sungrow received approval to restart production in February, it ensured that the necessary safety measures were in place and protections were available for its workers. Employees were provided gloves and masks, and temperature measurement at the entrance were strictly followed to prevent them from getting infected. Sungrow’ s 50-gigawatt capacity factory is equipped with high level of automation and state of the art technologies. This high level of automation and spacious workshop helped the workers to maintain social distancing within the factory while doing their job on the shop floor. Workers were also prohibited from gatherings during lunch time at cafeteria and the food were delivered to respective workstations as an alternate method. Sungrow put together a task force to facilitate quick decision-making once it realized the severity of the COVID-19 impact. The company also took the cue from its earlier experience of crisis-management, due to the tariffs imposed on imported Chinese products as a result of the U. S. -China trade war. Sungrow had understood the importance of quickly reaching out to its suppliers to ensure the availability and access to the raw materials and components needed for inverter production and thereby minimizing the impact. Sungrow Indian team has also applied the same proactive approach to communicate and update timely to their customers.

DURING

HOW

FAR

The COVID-19 has had minimal impact on Sungrow’ s ability to deliver inverters, so far. Majority of the order bookings are still being completed on time, and those that are delayed are just a few weeks behind the original schedule. As per the data released by China Custom regarding Inverter export in Feb, 2020, Sungrow had the first place with export value exceeding $12 million (excluding the Indian factory segment). The company shipped total 943 MW in February, with almost 50% coming from China and India factory each. “For the first quarter, we were able to supply, in part, that is because the manufacturing was done prior to that period. We are in close touch with our customers regarding their order deliveries from China. Our India factory will also resume to production with necessary precautions and safety measures in line with our HQ strategy once we get the go ahead from Govt. ” said Mr. Sunil Badesra, Business Head of Sungrow India. Sungrow’ s production at its Headquarter was back at full capacity by early of March, 2020. Also, the orders for Indian market for upcoming projects in 2020 and 2021 are healthy to indicate years of steady growth ahead. Mr. Sunil also mentioned the caution about the recent development of COVID-19 across the globe and in India. “The severity of its impact is slowly starting to be seen in many parts of the world with lock downs, temporary shutdown of businesses in many countries as a preventive measure. Though we want to share the confidence, at the same time, we are living in a continuously evolving story with high level of uncertainty. The real impact is yet to be seen and hence communication with our customers is the key. ” said Mr. Sunil.
