ndia to reach RE Target Of 175 GW by 2022

Power and New and Renewable Energy Minister Raj Kumar Singh has exuded confidence that the renewable energy target of 175 gigawatt (GW) by 2022 would be achieved.Singh, who took charge of the ministries in the second term of Modi government, said 80GW of renewable energy has been established while another 24GW is under installation. Speaking about his priorities, he said the top priority will remain to achieve the targets set by the government.


ndia Achieves The Lowest Cost Producer Tag of Solar Power Globally

India is now the lowest-cost producer of solar power globally, according to a report by the International Renewable Energy Agency (IRENA). According to experts, India’s status of lowest-cost producer of solar power has multiple reasons. India has high solar potential that leads to improved asset utilization and the country imports majority of hardware for installation from China which is cheaper and helps cut the cost by a huge margin. Also, the cost of land and labor is cheaper than the rest of the world, it also contributes to low-cost production of solar power in India.

(GSECL) and Gujarat Narmada Valley Fertilizers & Chemicals Ltd (GNFC). Currently, BHEL has a portfolio of more than 850 MW of solar PV plants, of which nearly 500 MW has already been commissioned.


TPC Ltd Tenders 1 GW Of Solar Power Purchase

India’s largest power generation company and government-owned NTPC Limited has issued a tender inviting consumers to purchase solar power. This is a first-of-its-kind tender as to date only consumers (or agencies representing consumers) have issued tenders inviting developers to set up projects. NTPC is reported to have around 1.8 gigawatts of renewable energy capacity operational in India. NTPC has itself issued several tenders inviting developers to set up large-scale projects at solar power parks. Like its thermal power plants, NTPC looks for distribution utilities that are willing to buy solar power from these solar parks. Power is then sold at the tariff quoted by project developers to the distribution utilities, with NTPC playing little to no part in the transactions.


evision In PPAs To Adverse Impact Investor Sentiments


ndia Sees A Drop In Solar Energy Installations By 49% In Q1

As per some reports, solar energy installation dropped 49% to 1,737 MW in Q1 of this calendar year. It was 3,377 Mw in the same period a year ago. The reasons include the general election, no auctions and lack of finance availability. Similarly, rooftop installation saw a slow down and dropped 33 per cent over a year, after four quarters of solid growth.

Government of India Secretary (New and Renewable Energy) Anand Kumar has purportedly written a letter to Chief Secretary L.V. Subrahmanyam, suggesting to him to apprise Chief Minister Y.S. Jagan Mohan Reddy of the fact that revisiting the Power Purchase Agreements (PPAs) in the solar and wind energy sector would shake the confidence of investors and adversely affect the future bids and investments in the State and in the country. The letter referred to media reports that the State government is contemplating revisiting the PPAs, wherein the tariffs were either fixed by the State Electricity Regulatory

Prospective developers need to have worked on a minimum of 10 MW of operational capacity or more. Eligibility criteria for interested bidders specifies that among others local manufacturers of solar PV cells, modules or battery, PV system integrator, can also bid for this capacity.


inistry Seeks Removal Of Priority Lending Limit For Renewable Energy

The Ministry of New and Renewable Energy (MNRE) has decided to request the Reserve Bank of India to categorise renewable energy into a separate segment from power, and remove priority sector lending limit for the sector to ensure higher financing. The development is expected to help developers get access to easy finance. Power Minister R K Singh also pointed out that the tariffs discovered for several renewable energy projects in recent auctions are not unviable. He added that the maintenance cost of those projects is low and the efficiency is improving.

bottlenecks may become an impediment for the growth in RE targets for ground mounted capacity. What also needs to be done is getting connectivity to STU at 132 KV in the scheme of things. MNRE budget may be used for waiving off the transmission charges of the STUs for the bids under NTPC/SECI. This will accelerate the capacity building.

Has the industry started planning and implementing a recycling policy for solar equipment too? The answer would be “No”. However, people have started thinking about it. The investors are looking for the provisions in the financial model for the decommissioning and dismantling of the plant. The stock reply to such query from investor is that the plant will have the residual life of 3-5 years and the revenue during this period shall be adequately

What further policy interventions are required to accelerate the market in India? Solar sector in India is current going through many challenges in both phases of the projects i.e. Development and Operation. Operating projects face the issues of Backing down / curtailment by Discoms. The payment delays are mounting beyond 8-10 months from certain Discoms. The regulatory or administrative interventions are needed to be substantially enhanced to bring receivables

MNRE guidelines specifies that the developer shall be responsible for the disposal of the solar panel in accordance with the e waste rules (which incidentally do not cover PV modules). First Solar, the thin film manufacturer from US has incorporated the take back policy for its modules. However, one can be skeptical about such solution becoming a regulatory norm in the near future. The solar projects in India have started from 2009 and hence there is adequate time for the formulation of policies and implementing mechanisms for the recycling of solar panels.

to a reasonable level and ensure that the generating companies are able to meet their contractual obligations. For the projects under development/construction, there are uncertainties on GST. Different state authorities have different interpretations on the services contracts. Funding of Safeguard duty has become an additional burden on the developers. There is a further challenge of possible tariff reduction on the projects won post introduction of Safeguard Duty. In the aftermath of IL&FS issue, the liquidity in lending to this sector has become tight. With lack of long-term track record of generation performance in the sector, lenders are taking recourse to unrealistic generation numbers in assessment of solar projects. The solar sector needs to be considered separate from Conventional Power sector.

During FY 18-19, we have added 820 MW of solar projects to our portfolio, the majority of which comes from ISTS bids. This includes 50 MW solar floating project under SECI bid and first large scale IPP Solar floating bid from SECI.

Thankfully, the industry is coming together and MNRE is providing support to resolve the issues at various levels.

Do you think aggressive tariff caps for solar tenders hampers the investors sentiments? In theory, the aggressive caps on the tariffs should not deter the lowest tariff discovery as long as bids are received. However, prescribing the similar caps for the projects across the country is best avoided. The Solar radiation is different, so is the off-taker risk profile and land costs. We have now solar park vs non solar park and state Discoms vs NTPC/SECI distinctions in the projects which can be clearly seen in the discovered tariffs of such tariffs. Aggressive tariff caps and subsequent discovered tariffs has set a relatively low benchmark. Going forward, it may be difficult to sustain the same. This may result in off-taker delaying

Yes, the Solar sector has seen a slowdown since the last 3 quarters. Introduction of government policies such as Anti-Dumping and SafeGuard duties on imports of solar cells and modules has raised concerns amongst several solar developers and contributed towards this. Another major contribution for slowdown in the sector could also be attributed to the cancellation of auctions by SECI in Gujarat, Maharashtra and UP.

Could you brief us about your upcoming projects in the RE Sector? HREPL is executing several Open Access projects for high credit rated C&I Clients. These projects would be commissioned by the end of the year. Further, the Company is building a strong pipeline to support its vision of achieving GW level portfolio through both greenfield and brownfield approaches. The Company is also passionately looking to develop and provide EV charging and clean mobility solutions in the near future.

How do you see India’s growth in the Solar sector against the background of ambitious targets set by the Government of India? Currently India is the third largest market globally. Given the ambitious target of 175GW by 2020 in 2010 which was later revised to 100GW by 2020 in June 2015, India has managed to achieve a sizable portion since the inception of JNNSM in 2010.

This would help the country achieve stability in the grid. The ongoing progress can be achieved by bringing storage solutions into utility scale plants which can help in effective FAS. The Government is also working towards introducing green energy corridor schemes, which is a prerequisite for large scale grid integration of renewable energy

The Solar industry is presumably upbeat at the political stability at the Centre. What is your take on the renewed investment confidence for the Industry? Political stability at Centre is good news for the entire business community. A stable Government can always take difficult decisions for the good of industry which are not populist in nature. India’s green energy play is expected to grow substantially with federal policy think tank NITI Aayog projecting increased capacities by 2040 in its new draft energy policy. Government has already started on a 100 days programme to achieve some quick results in various areas affecting the business growth. However, the solar industry is still not fully confident and keenly watching policy announcements by the Government. Announcement of “Rent a Roof” policy by MNRE is a welcome step in this direction to drive Rooftop Solar. Once the framework and modalities are known, the industry can take it forward with fresh investments.

Sunvest Capital was launched in 2019 as an NBFC (Non-Banking Financial Company), to solve for the market gap in rooftop solar financing. We provide access to easy EMIs for reliable solar equipment that is installed by most trusted local installers in your area. We monitor your system across the life of the loan so you don’t worry about maintenance. Our journey has been from an installation company to a financier but our focus and vision have always been consistent. Every home and every business in India have the potential to go solar and drive economic, social and environmental benefits. We are playing our small part in Making Solar Possible.

What are the key challenges & main growth drivers in the rooftop solar segment? Challenges The key areas of development in the rooftop solar segment are: � Consistency in net metering processes � Clarity around subsidies � Easy access to financing � Need for quality / standardization of the equipment, installers � A strong push for consumer awareness The industry needs to work with the central and state governments and other regulatory bodies to work on streamlining the net metering and subsidy related processes. We have to work with the utilities and ensure there is a win-win for everyone. Industry can and must solve for the issues around access to financing and quality standards. Finally, I believe for consumer awareness, we need to come together as civil society and deliberate over the innumerable benefits of going solar. The awareness will increase only through dialogue and there has to be a mindset shift towards going green and going solar. In the past, we have seen the Government run very successful campaigns against social issues for example: cleanliness. We need something similar for decentralized solar adoption.

While large C&I projects have, to some extent, mitigated financing challenges via IPP routes and / or development finance, it’s the small-scale solar segment i.e. residential and small C&I that yet to see any robust financing solutions. At Sunvest Capital, we realized that for any high upfront investment like homes, cars, mobile phones, an easy loan product is essential. A solar loan is akin to your car loan or any other asset finance, where you put down a certain amount of margin and take a loan for the remainder amount. You repay your loan through EMIs over a certain tenure. Based on our market insights we have launched a solar loan product and I would like to share some details on the product and how we are with the customer across the solar loan journey:

Before the loan – Inspiring Trust � Equipment – Our proprietary methodology considers over 50 data points across quality, presence, strength, brand, service, technology, bankability to qualify the most reliable equipment. Additionally, we work with a leading global reliability and testing lab, where equipment gets tested for various technical parameters on an ongoing basis � Installers – India has many solar installers. Some are fly by night and some will stay the course. We know it’s hard for you to decide, hence we use a rigorous process to verify a network of trusted installer partners. We have obtained detailed feedback from their existing customers, conducted audits on their solar projects and checked their ability to execute high quality projects and obtain requisite approvals from authorities

The Solar Loan – Easy EMIs � You put down 30% margin, we finance the rest, such that your EMI will pay out of your electricity bill savings � No collateral over and above the solar system � Our fintech algorithms mean less paper and faster loans

Please brief us about your company’s product and solutions offerings? ACVA Solar Pvt. Ltd. is a MNRE approved channel partner established since 2010, by three young entrepreneurs. It’s a premier organization undertaking the Design, Integration, Installation & Commissioning and Maintenance of Photovoltaic Solar Power Systems. ACVA Solar is established with the goal of developing a customer-centric and risk free technology to harness solar energy; and to help provide a cost-effective and environmentally sustainable solution to meet the energy needs of India. ACVA Solar Pvt.

It also has tie up with international players like Schott Solar & Darfon. Its application development work includes “reverse grid feedback controller” and the first ever “type test” of solar+wind hybrid system at RDSO Lucknow for Indian Railways. The ACVA Products at a glance:

Additionally reducing prices and competition has seen corresponding reduced margins which are un-tenable, given the larger life cycle of the projects. Also the advent of inexperienced entrepreneurs has seen unsustainable prices. The effect of this is very much evident by way of shakeout in the industry and the landscape being full of failed enterprises. Government through MNRE, State Nodal Agencies with concerned departments need to make concentrated efforts to establish the standards of components and implement and strictly adhere to the set standards in the systems that are implemented. Increasingly substandard or qualitatively cheap material is being installed which may not last the intended lifetime of the system/product. Here all the stakeholders including the Government not to mention the Owners of the projects are going to be big losers. The real impact will be felt over the next half a decade with systems maturing over the next couple of years and real impact of harsh conditions are experienced.

Is net metering a success story in the state of Gujarat? Very much “Yes”. Even though the open access and third party sale of solar electricity is still

Safeguard Duty is a step in the right direction by the Govt. to support and promote a healthy national solar environment. However, the effect has been nullified to some extent by levying the same only on certain countries of origin of the product. This stipulation has been circumvented by some operators and nullified the impact to an extent.

the strategy chosen.

contributing to this trend could be that growing numbers of auctions are being designed to achieve additional objectives other than price. One of those objectives is supporting the integration of variable renewable energy (VRE). Solar PV and wind are the most commonly auctioned renewable energy technologies, accounting for 97% of auction volume in 20172018. This reflects a global trend over the past decade: Solar PV and onshore wind are also the most widely deployed renewable energy technologies by a large margin, driven by their growing maturity and falling costs. VRE, however, has characteristics that distinguish it from other generation sources, related to its dependency on the weather. VRE technologies are relatively more limited in the degree to which their output (and consequently their dispatchability) can be controlled, and they exhibit seasonal and diurnal (i.e. within-day) variability in its patterns of production. VRE generation can be forecast, but not without some uncertainty. Variability

The strategies are ordered according to the degree of central planning required, from the highest to the lowest. For example, under the project-based strategy, developers have little flexibility in the design of their power plants, whereas the product-based strategy allows them the maximum degree of flexibility: they need only to guarantee the availability of a predetermined quantity of a given product (capacity, energy, system services, etc.). While this framework may hide nuances, it attempts to classify design options according to a predetermined approach to system integration that reflects country conditions (resources, power market structure, objectives, etc.). PROJECT-BASED STRATEGY: Where this strategy is being applied, outcomes are highly predictable, as central planners maintain tight control. Parameters such as the size and location of projects, as well as the technology involved, are determined before the auction.

WHAT ARE THE BIG CHALLENGES FACED while installing solar energy projects in manufacturing industries? Mr. Raghav Malhotra Global Head of Project Management Cleantech Solar

all works performed, demarcated work areas and constant on-site oversight by Cleantech Solar’s project management team. Cleantech Solar follows the hierarchy of control with respect to health & safety and to drive electrical safety, only fully qualified electrical workers are permitted to work on or near exposed energized parts. In addition, Cleantech Solar’s

In our extensive experience with manufacturing clients with global presence, we observe two major categories of challenges faced while installing solar energy projects in this industry: the expectation of the highest safety standards and overcoming en-route technical challenges. Safety concerns mainly arise from the risks associated with working at heights with electrical components, while technical concerns arise out of site preservation as well as ensuring the day-to-day operations of the customer are not hindered during the installation. To help manufacturing companies implement solar plants in compliance with their stringent safety standards, Cleantech Solar has its proprietary protocols and procedures that are presented and discussed with the customer prior to the installation activities on site. These are then tailored as per site-specific requirements to ensure compliance with the customer safety requirements and operational constraints. The main components of our protocol and process control are high-quality safety equipment such as lifelines, walkways and handrails, along with strict adherence to industry best practices such as maintaining a minimum exclusion zone from the edges of the roof, a buddy-system for

design also implements global practices that minimize risks associated with electrical works through the implementation of redundancies and best practices such as ‘lightning loops’, which are unique to Cleantech Solar’s plants in India. Site preservation is critical to the smooth operations of the customer’s business activities. To address this, Cleantech Solar conducts necessary structural analysis of the roof to ensure its stability with solar loads and conducts a pre-construction survey that documents all defects present on the roof so that the same can be rectified to ensure the longevity of the roof. During installation, all man and material movements are restricted to temporary and/or permanent walkways to ensure the load capacity of the roof is not exceeded and the roof condition is preserved. The Cleantech Solar project management philosophy facilitates continuous feedback and improvement throughout the project installation cycle. By virtue of our industry-leading practices and processes, Cleantech Solar has been able to build a highly trusted brand and a solid track record of delivering safe, reliable and repeatable solar projects for the manufacturing sector.

Industrial consumers are now blessed with a plethora of options when it comes to power portfolio management. Earlier they were confined to either Discom supply or captive generation. With the advent of Exchange, they were given access to the market based competitive prices. Imposition of various tariff and operational barrier did slow down the growth of open access segment. Lately, falling prices complemented with generous public policies made renewable a blue eyed boy and now everyone wants RE in their energy pie. In fact the convergence of conventional and renewable power prices is nudging industries to compare them on commercially level playing field also. Although. the large scale grid connected RE projects set up under competitive bidding, with waiver of ISTS transmission losses and charges, are allocated to Discoms only. As a result, Industries are left with an option to either go for third party (interstate or intrastate) or captive. Such interstate transactions will have no waivers/exemptions and RE project has to purely compete on the energy cost. In case of intra-state, currently freebees in form

is absorbed by Discoms through banking provisions. It was manageable till the time renewable had a smaller pie in the total generation mix. With this pie expected to be dominant in the near future such preferential treatment may not be a sustainable option for long and eventually will fade away. With such a scenario in hindsight industries may find it really tough to commit for a longer duration PPA on the other hand developer may not be in a position to accept a shorter duration PPA as it put its capacity at financial risk. It is of utmost importance for an industry to take an informed decision and create a portfolio of available options for power procurement and try to leverage all options which complement its energy need and load profile. It is worth mentioning here that Indian Energy Exchange (IEX) plan to introduce Green power market which will facilitate industries to buy bundled power to meet their energy needs and also RPO compliance. One important question which still needs retrospection whether industries want to go for ‘green power’ as a sustainability measure or ‘cheaper green power’ as economical measure.

The Philippines received the lowest bid of USD 43.9/ MWh for a 50 MW auction (Billini, 2018). Onshore wind was auctioned primarily in Europe, followed by South and East Asia and the Pacific, driven by the richness of wind resources in these regions. Germany alone auctioned more than 6 GW in seven rounds during the period at an average price of USD57.17 MWh. Offshore wind auctions saw considerable uptake in Central and Western Asia, led by the announcement of a 1.2 GW auctions in Turkey (Tisheva, 2018). Biomass auctions were concentrated in

they were unable to gain from the fall in the prices of solar equipment. The introduction of GST has certainly simplified tax regime in the country, and rooftop solar too like other business sectors observed a stuttered growth compared to its potential but as the business at large adapts to the GST and teething problems are reduced, we don’t see GST as a dampener in the growth of rooftop solar sector in the long term.

No doubt that GST has imposed extra burden on the industry but I think That solar is now a grown up child and it can contribute this much to the economy.

Since the Electricity we consume is not in GST purview the GST paid on projects could not be claimed by the clients which in terms increases the Cost of project for the clients on a product or service which was earlier tax free.

The industry is of the view that applying 18% tax would derail India’s plan to add 100 GW of green power by 2022. Intense competition in recent years has driven down solar power tariff discovered in project auctions.

As is evident, components of solar power plant system comprise about 85% of total project cost. Any increase or decrease in cost of system components, due to GST would directly impact the project cost. Apart from the direct impact of GST on solar tariff, there are likely to be other developments in the solar sector after the implementation of the GST regime, which could either promote or hinder solar development in India in both the short and long run.

Mr. Naresh Bazzar Co-Founder & Senior Business Development Analyst GSE Renewables India Pvt. Ltd. Maharashtra’s appellate authority for advance ruling (AAAR) on 5 September 2018 set 18% as GST on solar projects cost considering service and 5% as GST on solar projects cost considering material, endorsing an earlier ruling by the statelevel authority for advance ruling (AAR) and dismissing solar developers’ demand to be taxed at a lower 5%.

the GST implication. Sudden changes in the GST rate from 5% to 8.9% mainly affected ongoing solar rooftop projects i.e. the projects registered under Subsidy Scheme for Solar Rooftop has affected the Purchase of EPC (engineering procurement and construction) Developers. Though it can be beneficial for Ground Mounted Solar Systems as there is more Civil and Construction work is involved in comparison to Rooftop Projects. Many EPC developers who are more in solar Rooftop Projects are demanding to have 90:10 Service to goods ratio to avail the benefits of solar or uniform 5% GST throughout the country. The Uniform Clarification on GST will Boost up the government’s target of 175 GW of renewable power by 2022 which includes 100 GW of solar power.

If India is targeting 100 gig watts (GW) of solar power capacity by 2022, up from the 23GW at present then applying such higher GST rate will slow down the said 100 gig watts target. The country has a total renewable power generation capacity of over 70GW currently, half of which comes from wind power. Even intense competition in recent years has driven down solar power tariff discovered in project auctions and factors that helped producers bid for projects aggressively using measures including lower prices of imported solar panels and efficient financial structuring of projects. However increase in efficiency due to GST will impact growth and flourishing of solar for captive consumer driving capex investment in solar, GST inward tax credit can be set off against outward supply but RESCO investment where set off is not possible and as a result it causes enhancement in Solar tariff to consumer and reduces its saving up to great extent and as a result solar become bit less lucrative.

What Is The Potential Of Hybridisation Of Existing Wind/Solar PV Plants? Mr. Prabhat Kiran Business Head – Technical Assistance Program SunAura Technologies Pvt. Ltd.

Mr. Rajsekhar Budhavarapu Independent Business Consultant/Entrepreneur

A “Wind-Solar Hybrid Power Project” means a hybrid project where the rated power capacity of one resource is at least 25% of the rated power capacity of the other. In a wind-solar hybrid power plants, both the Wind Turbine Generators (WTGs) and the Solar PV systems will be configured to operate at the same point of grid connection.

RE-Hybrids with co-located storage solutions has the ultimate

It would, though, be very helpful if the GoI estimates the cost of Variable RE (VRE) grid integration, for it would help value FRE better.

Should it serve Round-The-Clock (RTC) power for 24 hours or 18 hours or 12 hours or 6 hours or be construed as firm dispatchable power for shorter periods.

� More balanced power mix for sale Potential of Solar-Wind Hybridization in India: Superimposition of wind and solar resource maps of India show that there are large areas where both wind and solar have high to moderate potential. Thus, it would be very advantageous if the existing wind farms are augmented with added solar PV capacity and similarly wind turbines could be setup in the vicinity of an existing solar PV plant. Most of the Indian states are endowed with good solar irradiation levels and the states of Gujarat, Rajasthan, Karnataka, Andhra Pradesh, Telangana and Madhya Pradesh, with a high wind potential i.e. above 200 W/m2 (minimum wind speed of 6 m/s at 50 m) and with a solar radiation level between 5-6 kWh/m2/day2, have been deduced to be the most suitable sites for Wind-Solar hybrid projects. According to industry estimates and studies, the efficiency of standalone wind and solar projects range between 18 to 28 percent of the installed capacity. With the hybrid power plants, that figure can jump up to 40 percent! India has witnessed an exponential growth in the renewable energy sector in the last five years. As of December 2018, 35.29 GW of Wind and 26.03 GW of solar capacities have been installed. What we are about to witness next is a wave of Wind-Solar Hybridization in India.

or purely from the administrative ease perspective. We also need to exercise caution from having a very fixed definition, for there should not be any difficulty in the future for accommodating changes (in configuration) on account of technology advances at legacy projects (installed under previous RE-hybrid definition). Answers to the above questions, would allow us to either look at RE-hybrids purely as Wind-Solar PV configuration [with defined ratios] or as any configuration between different RE technologies and any ratio. It may be noteworthy that Solar CSP-Solar PV hybrid projects with over 15 hours of energy storage via molten-salt, are already known to provide competitive utility-scale firm & dispatchable power. Should such projects be also part of RE-hybrid project definition in India?

Mr. Kunj J. Shah CMD, Zodiac Energy Limited Chairman, Renewable Energy Committee, ASSOCHAM Gujarat Chapter The technologies for harnessing solar energy in India are constantly evolving to reduce the overall levelised cost of energy (LCOE) from solar energy. With the prices of major solar components hitting its bottom and now bouncing back due to increasing global demand, following are the key engineering trends in Utility scale Solar PV Power Plants, which can be drivers to bring down the LCOE in utility scale solar power plants. 1. 1500 Vdc Solar Modules: Modules and inverter system voltage (inverter DC input voltage) has changed from 1000Vdc to 1500Vdc in recent days. This allows more numbers of modules to be connected per string. It allows reduction of costs by reducing the land area, cable length and cost of AJB/DCDB etc. 2. Bifacial Solar Modules: Bifacial is the latest module technology which is trending in solar PV market.A typical 72 Cell module can have a maximum of 420Wp whereas a multicrystalline can produce a maximum of 330Wp or 340Wp in same area. It allows reduction of costs by reducing the land area, cable length, Module mounting Structure tonnage, Civil Foundation and cost of AJB/DCDB etc. 3. MonoPerc Solar Modules:

Mr. Samrat Laha Director Solace Renewable Energy Private Limited

India has witnessed the integration of utility scale solar power plants at different parts of the country to achieve its goal of carbon dioxide mitigation over a decade. But a rapid growth in the solar market has been witnessed in the last four years. Innovative approach along with cutting edge technology has increased the load factor of solar power conditioning units, reduced the size of solar photovoltaic modules with appreciable increase in their respective efficiencies.

Mr. Yogendu Joshi Principal Associate Tatva Power Projects And Associates Utility-scale solar has been expanding fast on PAN INDIA basis due to its cost competitiveness and day by day is improving accordingly. During initial stage viability of the Large Scale Projects was based upon cost of Technology. After grown up of 10+ Years in Gujarat, the cost momentum of large scale projects turn up in to more of a LAND cost, Transmission Line Cost & Substation Cost. Due to technological upgradation the pressure on costs, margins and speed is intense, and most of the solar companies have dominated the industry so far. Now the key question is, will this trend continue, or does utility-scale solar can hold viable opportunities for energy incumbents going forward? As per global trend LOCE (Levelized Cost of Energy) decreased by 68%. Now to search answer of our Key Question against LOCE, some of the healthy Engineering Selection Required :� Selection of Land :- As we know, for large scale projects, huge amount of land required. And selection of Land is playing major role to balance capital investment. And hence it is

w w w . s o l a r q u a r t e r . c o m

efficiency (~99%), which are standard features of Sungrow Inverters, help large scale utility projects to generate better yield and thereby higher ROI.

The benefits of MonoPerc solar modules are also similar to that of bifacial solar modules, it is one of the latest technologies in Mono crystalline solar modules, wherein the module efficiencies are higher compared to typical polycrystalline modules. 4. Single Axis tracker: Single axis tracker helps achieving higher energy generation in projects in Northern parts of India and as a result, the cost of Land, MMS, and civil foundation etc reduced thus reducing overall project costs and LCOE. Combination of Bifacial solar module with single Axis Tracker gives better LCOE for utility scale solar projects. 5. Robotic Module cleaning: Robotic Module cleaning reduces the consumption of water and manpower costs for O&M of Solar Power Plants. It also reduces the soiling losses resulting in higher generation from plant and lowering LCOE. 6. Floating Solar PV Plants: Floating Solar PV Plants are built on water bodies. Though the BOS cost is high in floating solar, it has zero land cost and costs associated with land development. Also due to lower temperature of the modules, the energy yield are higher in floating solar power plants. All these factors results in lowering the LCOE. Proper engineering on case to case basis by employing one or more of the above can result in to the lower LCOE over the plant life cycle.

Recent developments in material composition of solar modules by stacking three separate layers of solid state elements at the base have enhanced its optical property, making it capable of absorbing light wave of various wavelengths. Development of antireflective encapsulant stands out to be a major reason for an increased energy conversion capacity of present solar modules. Modern trend of microcontroller based automatic cleaning robots capable to sprinkle water on requires an area of the solar modules moving across the surface of the solar arrays is an advanced solution. This automatic cleaning solution alongside real time remote monitoring system brings in precision and effectively optimize the maintenance operation. Modern engineering approach has made it possible to setup solar power plants from few hundred kilowatt to megawatt scale at little to least structural cost on roof sheds. This innovative approach for designing of compact module mounting brackets to hold solar modules with optimal mechanical and thermal strength has also bring down the cost of large capacity solar power plants in no time.

advisable to select land which are more of a flat in contour to avoid Land development cost. Also preferably land must be near to Discom’s Substation to avoid huge cost of Transmission Line & ROW charges. � Selection of Technology :- Major cost in Solar System is based upon PV module & Inverter. However nowadays selection of ancillaries like Cables, Structures are playing a major role. And that is the reason Value Engineering of project designing is most important i.e. using most efficient design, identification of shortest routes, avoiding complexity and maximum use of renowned components. Designing most efficient system is not always setting up economics of the project. But agility in selection without compromising of output is most important. In many cases Small Scale of String Inverters are cost effective compared to Centralized Grid Tie Inverters. Use of Aluminum cable against copper is always debatable for LOSSES but definitely wiser use of Aluminum cable can set the economics of the project. � Financial Modeling :- Though it is not part of technology but most of the projects are based upon Financial Modeling to estimate ROI. Contribution of Loan Interest Components is vital. To take care of budget, burden of interest components must be minimum. In nutshell, Solar Industry to keep on learning new technology and to develop the use of integrated system, right use of resources, close study of market, policies & customized approach for every land parcel are important.

The Rising Sun and the occasional cloud Forty years ago, when President Jimmy Carter installed 32 solar panels on the roof of The White House, little did the world realise that it was an important step towards ushering in an era of a clean, reliable and abundantly available natural energy source. Countries across the globe are increasing focusing on renewable energy to sustainably fuel their growth plans, which as yet have heavily relied on fast depleting and often polluting carbon fuel. India, too, has taken ambitious strides in leveraging its geographic advantage that offers abundant sunshine over vast areas for most of the year. India installed 8.3GW of solar capacity in 2018 and that formed roughly 8% of global installations (104 GW). While the number may first seem impressive, it gets dwarfed when compared to China’s installation of 44.3GW. India’s per capita power consumption (0.6 tons oil equivalent per year) is low in its peer group of BRIC countries (China leads the pack at about 2.6 tons oil equivalent per year) and that emphasises the potential energy-requirement for the future. India is hoping to achieve most of that energy requirement from its ambitious plan of 100GW of solar energy by 2022. The opportunities and challenges that await India as it readies to accomplish the mission are many and all the key stakeholders, the Government of India (GoI) through MNRE (Ministry of New and Renewable Energy), the SECI (Solar Energy Corporation of India), IPPs (Independent Power Producers), DISCOMs (Distribution Companies), financers and the risk management community, have an all-important role to play. As per the GoI’s stated objective, about 40% of the installed capacity by 2022 needs to come from solar parks. Considering the challenges and sensitivities around land acquisition and infrastructural requirement for power evacuation, solar parks provide a comparatively hassle-free solution. While the intention is well-founded, execution remains a challenge and delay in commissioning dates is leading to cost escalations.

The role of risk management, therefore, over the large cycle of 25 years becomes very important. Well considered safeguards need to be incorporated at the drawing-board stage itself. Besides the obvious risks of property damage caused by natural and man-made perils, the projects should be able to cope with and respond to deteriorating power generation caused by excessive panel degradation and lower than expected radiation.

The way forward The success of solar relies heavily on visioning goals that encourage stable and sustainable long term development. Although power primarily remains as a state subject, increased collaboration and coordination between the centre and state will be crucial to improve efficiencies while also articulating a clearer industry roadmap. Similarly, industry associations need to work in tandem with policy makers and risk managers to create a knowledge repository and leverage data more effectively to better understand and mitigate risk. This will improve the long term project sustainability and financial viability for all involved stakeholders. Renewable energy has the potential to create many employment opportunities, especially in rural areas. Apart from providing energy security, the large savings generated can also be better utilised in a fast developing country. India is slowly but surely gaining global prominence in the generation of solar power and the rising sun bears testimony to it.

Compared to 2017, there was an approximate 11% drop in fresh capacity addition in 2018 as far as PV installation is concerned. While demanding lower solar tariffs, the policy making machinery would be well advised to take a holistic view of the surrounding complex situation. This includes a combination of factors like auction cancellations, safeguard duty on imported panels, GST implications and the volatile rupee – all shrinking the profit margins of IPPs. With more than 88% of panels still being imported from China and Malaysia, we still have a long way to go as far as the “Make in India” drive is concerned. The scale and expertise achieved by large-scale Chinese players still eludes local panel producers. The apprehensions of IPPs regarding Indian panel producers need to be allayed by offering quality products backed by long term panel warranties, as is the case with Chinese imports. Likewise, Risk Managers and Insurers need to be closely involved right from the conceptualisation stage to ensure technical and financial viability while at the same time develop products that will instill confidence and facilitate enterprise level risk-taking.

MR. SUMIT DUTT Head – Property and Casualty, Willis Towers Watson India Insurance Brokers

MR. SAURABH VERMA Executive Vice President–Property & Casualty, Willis Towers Watson India Insurance Brokers

On one hand, IPPs cite hyper competitive pricing as a major impediment for investments in comprehensive risk management, and on the other, insurers remain cautious of offering long-term insurance products. Given the nature of contracts that need to provide cover for as long as 25 years, the risks are many, including radiation changes over the years, panel performance, power evacuation on a committed basis and timely payouts. Other factors such as the recent NBFC financial situation, auction cancellation of PV projects in Gujarat (which incidentally adopted a renewal energy policy quite early), Karnataka stopping any new solar energy projects, have all further exacerbated the challenge for IPPs. It is no wonder that new capacity additions is almost flattened in 2018 giving the policy makers jitters.

Policy making and regulatory framework The SECI, entrusted as the custodian of the solar mission in India, holds the key to developing a fertile ground for solar projects to sustain and thrive. While attractive pricing will provide financial incentives for solar power generation, hyper competition introduced by way of maximum ceiling price-driven tenders are detrimental to all. Panel standardisation and approval should be the starting point to bring homogeneity in the entire eco-system. The role of MNRE could also evolve on the lines of SEBI or TRAI with an increased impetus towards setting standards, best practice implementation, governance and compliance. The certification of panels is an immediate concern and it is alarming that the backbone on which solar expects to build, i.e. the solar panels, are devoid of any certification besides the basic ones by IEC (International Electrotechnical Commission, a global standards body for solar panels). The government, also needs to do its bit in ensuring grid-stability as increasingly, this is getting tested against sporadic power production. Smart grid still remains a challenge and there needs to be a long term commitment to address issues around balancing.

Risk management framework Whether it be dependency, asset idling during night time, large scale land requirement, cutthroat bidding or long tail nature of PPAs, the solar energy space is as perilous as it is prized. Given the long term nature of PPAs, it is imperative that key risks like cost risks, schedule risks, performance risks and operational risks are all identified and mitigated. While the lack of actuarial data in a nascent industry, such as solar, makes it challenging to structure and/or price risks, a well detailed risk mitigation framework can be a first crucial step towards addressing this issue. This, however, calls for a paradigm shift in the mindset while dealing with solar projects, which only have a fixed cost and practically non-existent variable cost. Borrowing solutions from other power generation channels like thermal or hydro power will not be suitable in this case.

Further, the PR for mono based power plant was found to be 81.70%, which is at an average 0.62% higher than poly based power plant. Overall, it was found that implementing mono crystalline modules would enable the end customer to annually generate 13.7 MWh (refer Figure 3) more.

Found mostly in coastal areas in India, this zone is mostly recognized by its humid climatic conditions around the year. Further, they may experience summers with temperatures ranging from 35~42 °C coupled with moderate winters. Accounting to mostly moderate to sometimes high temperatures around the year, the power plant utilizing mono modules are expected to save 0.84 kWh/kWp/day attributed to temperature losses. Compared to summer, the winter experiences 5.10 % gain in the PR, thanks to the clear skies. Further, mono crystalline based power plants experience a gain of 2.95% over the plants utilizing poly crystalline modules. Additionally, it is expected that utilizing mono technology shall enhance the output of power plant by 0.16 kWh/kWp/day. This gain when considered for power plant based on fixed area would result in 45.5 MWh more (refer Figure 4) energy generated from a mono crystalline module based plant.

This zone typically has the climatic combination of both hot & dry and moderate zone i.e. it has extreme summers and extreme winters while the monsoon are typically coupled with cloud covers. Pertaining to such extremities, the temperature loss in a mono crystalline plant stays at 23.5 kWh/kWp which is 1.20 kWh/kWp less than that obtained in a poly crystalline based plant.

The mono crystalline based power plant injects 10.3 MWh (or 7.67%) more energy into the grid per MW of power plant installed in such areas (refer Figure 5 for more details).

While the monsoons are coupled with cloud cover, they stay relatively short in this zone.

Moderate climatic zone Moderate climates are known to be balanced throughout the year. Such climatic zones, other than its intensely cloudy monsoons are considered preferable conditions for a solar power plant. When comparing power plant in fixed area, we find that the average energy gain of mono over poly stands fairly constant throughout the year i.e. at 17.65%. Further owing to the fact the ambient temperature in this zone remains fairly constant throughout the year, the gain over temperature losses remain equivalent to around 1.00 kWh/kWp throughout the year. The performance of the overall power plant however is known to be much better when a plant uses mono crystalline module i.e. 50,621 units more (refer Figure 6).

Will Your Modules Perform for 25+ Years?

Convincing investors, insurers, developers and policy makers that PV modules will reliably produce power for 25-35 years has become increasingly important, given the need for sustainable and affordable power that is accessible to all consumers. . PV modules in India are subjected to climatic extremes including higher solar insolation, UV, temperatures, dust, precipitation, compared with several countries where solar installations have happened. Solar panels need to withstand the combined effect of these stresses to avoid pre-mature appearance of project performance issues. Now, more than ever, it is critical that the materials used in your module be reliable for the duration of its operational service life. As service lifetime expectations of PV modules continue to grow, it is important that we understand the impact of PV materials durability on module performance and safety so that different stakeholders can make informed decisions on materials selection. Backsheets, in particular, play an important role in ensuring your module will be sufficiently durable to reach your financial objectives. While a module may pass standard qualification tests, backsheet defects can develop after just a few years of deployment in the field.
