Do's and Don'ts for Indian MW Solar Power Plant


There are three main categories of solar power plant developers in India:

  1. Super duper companies such as Sun Edison, Welspun Energy etc that are both large and financially well-heeled, as well have real professional expertise in putting up solar power plants, both large and small.

  2. Small-medium companies that are existing business keen on solar power, but not well versed with putting up MW solar power plants

  3. Individuals (usually high net worth) who are perhaps experts in some other profession (doctors, software professionals…) but know next to nothing about solar power plants.


This post is not for the first category, though who knows, anyone can improve!


This post is for categories 2 & 3 – folks who are keen, and can afford, to invest in MW solar power plants, but know little about these.

For many of them in this category, it is important that they understand the Dos and Donts of putting up MW scale solar power plants. Such an understanding can make a big difference between making a few additional crores of rupees – or LOSING THOSE FEW ADDITIONAL CRORES!

This post is for them. I’m not going to give you the do-s and dont-s by the busloads. Just 3 of them in each!



  • Do not invest on anything tangible without a PPA. This must be obvious, but we find that a number of prospective developers start keenly investing in land especially without a PPA in hand. Don’t. Focus your energies on getting a PPA.

  • Do not go for an EPC based on your friends’ or relatives recommendations. How many of your friends or relatives could really be experts in solar? I would bet very few or hardly any. So why would you go with a non-expert’s recommendation on such a vital selection as an EPC? Don’t. Do your research or talk to industry experts before deciding on an EPC.

  • Do not skimp on costs and end up with lousy panels, inverters or other BoS. This is an old warning, and one presumes that every solar developer worth his salt would be knowing this. But surprise, surprise, we still find some developers’ first question being “is this the cheapest product?” instead of “is this the best product?”


  • Ensure you are bidding at a tariff that will provide you a decent financial return. The country has seen some ridiculously low bids from companies that most likely are not in a position to bid those prices – we are not talking about Sun Edison or Softbank who probably can bid at low prices and still make money because of their scale and access to competitive financing. Unless you have the AD (accelerated depreciation) benefit, make sure that your bid tariffs will give you project IRRs of at least 12%.

  • Get an expert to be with you from beginning until the first unit of power is generated. All right, we definitely are doing a bit of self-promotion here!, but seriously you don’t have to necessarily appoint a consultant like us, at least make sure that there is someone in your friends or close business contacts someone who can handhold you throughout the process. Don’t try to avoid getting professional help because of the few lakhs you could be spending on this.

  • Consult with more than one bank, and include consultations with IREDA as part of your financing. We have seen that most banks start negotiating tough, but we have also seen they had come down on their rates once the clients were able to prove they can bring good collateral security and also show that other banks or financial organizations such as IREDA are able to fund at much lower rates. Spend enough time researching other banks and bargaining for the best deal.

Hope I made some sense, and hope these 3 dos and don’t are indeed useful to you.

I look forward to your questions and comments.


And all the best to your solar power plant efforts!

  • It doesn’t generate much power, but it works during the one time of day that solar cells can’t: night. Aaswath Raman was driving through a village in Sierra Leone in 2013 when an idea came to him as suddenly as, perhaps, a light bulb switching on. The village was not equipped with electricity, and Dr. Raman, an electrical engineer at the University of California, Los Angeles, was unaware he was in a village until he heard the voices of shadowed human figures. “It took us about five minutes to realize we were passing through a town, because it was completely dark,” Dr. Raman said. “There wasn’t a single light on.” Dr. Raman wondered whether he could use all that darkness to make something to light it up, not unlike the way that solar panels generate electricity from the sun’s heat and light. He did. In new research published on Thursday in the journal Joule, Dr. Raman demonstrated a way to harness a dark night sky to power a light bulb. His prototype device employs radiative cooling, the phenomenon that makes buildings and parks feel cooler than the surrounding air after sunset. As Dr. Raman’s device releases heat, it does so unevenly, the top side cooling more than the bottom. It then converts the difference in heat into electricity. In the paper, Dr. Raman described how the device, when connected to a voltage converter, was able to power a white LED. “The core enabling feature of this device is that it can cool down,” Dr. Raman said. Jeffrey C. Grossman , a materials scientist at the Massachusetts Institute of Technology who studies passive cooling and solar technology, said the work was “quite exciting” and showed promise for the development of low-power applications at night. “They have suggested reasonable paths for increasing the performance of their device,” Dr. Grossman said. “But there is definitely a long way to go if they want to use it as an alternative to adding battery storage for solar cells.” Everything emits heat, according to the laws of thermodynamics. At night, when one side of Earth turns away from the sun, its buildings, streets and jacket-less people cool off. If no clouds are present to trap warmth, objects on the Earth can lose so much heat that they reach a lower temperature than the air surrounding them. This is why blades of grass may be glazed in frost on clear fall mornings, even when the air temperature is above freezing. The cloudless atmosphere becomes a porthole to the void, through which warmth flows like air through a porch screen. Read more....
  • What sounds more innovative than ‘solar paint’? A paint that can generate electricity, but still works as normal paint? The ability to turn not only a roof, but an entire building into a solar-generating surface? If that doesn't scream innovation, then I don't know what does. So far, the lifeblood of the solar industry has been traditional photovoltaic solar panels. Solar panels are a well-proven technology that save homeowners a ton of money. However, the hassle and expense of rooftop panel installations often deter people from switching to solar energy. Now imagine a world where we could simply paint our roofs and walls with a type of paint that can generate electricity. I am imagining this world - and it looks very promising. So, what is solar paint? The most important thing to know is that it isn’t a single product; currently there are three different technologies that are referred to as 'solar paint'. The 3 types of solar paint The idea of using a paint-like substance to generate electricity has been discussed within the scientific community for many years. Only recently have promising, real-world applications emerged. There are three separate innovations that are classified as solar paints. Here we explore what they are and what they might mean for the future of solar energy. #1 Solar paint Hydrogen A team of researchers from the Royal Melbourne Institute of Technology (RMIT) have developed solar paint that generates energy from water vapor . Put simply, the paint works by absorbing moisture from the air and using solar energy to break the water molecules into hydrogen and oxygen. The hydrogen can then be used to produce clean energy. This is how the paint actually works: it contains a newly developed substance, synthetic molybdenum-sulphide. Absorbing moisture from the air, it works similarly to silica gel, which you’ve undoubtedly seen packaged with consumer products in order to keep them dry. This solar paint also contains titanium oxide, a substance already present in conventional paint. The titanium oxide helps the paint use solar energy to break down the absorbed moisture into hydrogen and oxygen particles. The hydrogen can then be used to produce clean energy. #2 Quantum dot solar cells, aka photovoltaic paint Quantum dots, also known as photovoltaic paint, were developed at the University of Toronto. They are nanoscale semiconductors that can capture light and turn it into an electric current. ‘Colloidal quantum dot photovoltaics’ - to use the full technical term - are not only cheaper to manufacture, but are also significantly more efficient than traditional solar cells. According to research paper author Susanna Thon, “There are two advantages to colloidal quantum dots. First, they’re much cheaper, so they reduce the cost of electricity generation measured in cost per watt of power. But the main advantage is that by simply changing the size of the quantum dot, you can change its light-absorption spectrum.”  These dots could end up being up to 11% more efficient than traditional solar panels. At some point in the future, we might even be able to paint these quantum dots on our roofs and other surfaces in order to transform sunlight into electricity. #3: Perovskite solar paint Known alternatively as spray-on solar cells , what makes this type of solar paint possible is Perovskites. Named after Russian mineralogist Lev Perovski, Perovskite materials are derived from a calcium titanium oxide mineral. Perovskite structure was first discovered in 1839, but it was only 10 years ago that a research team in Japan debuted the first-ever application of Perovskite for the production of solar cells. There are many properties that make Perovskite solar cells special, but the most revolutionary is the fact that they can take liquid form, making them the perfect candidate for solar paint. In fact, researchers have developed a way to spray liquid perovskite cells on surfaces, known as spray-on solar cells. The first-ever spray-on solar cell was developed at the University of Sheffield in 2014. A Perovskite-based mixture was sprayed onto a surface to form a sun-harnessing layer. Out of all the new inventions that could potentially revolutionize the solar industry, Perovskite cells are possibly the most promising. Read more...
  • In the area of solar rooftop installations, Gujarat has stood first in the country with total 261.97 megawatts (MW) of installed rooftop solar capacity as on July 23, 2019. As per the Central government data, total rooftop solar installations in India is 1700.54 MW. Responding to a question raised by MP Parimal Nathwani in Rajya Sabha, Union Minister of State for New and Renewable Energy and Power R K Singh informed that Maharashtra and Tamil Nadu have solar rooftop installations at 198.52 MW and 151.62 MW respectively. The government of India has provided total financial assistance or incentives of Rs 678.01 crore in fiscal 2016-17, Rs 169.73 crore for fiscal 2017-18 and Rs 446.77 crore in fiscal 2018-19 under the Grid-Connected Rooftop Solar programme, the official statement said. The Government of India has set a target of installation of 40,000 MW of Rooftop Solar (RTS) projects by the year 2022 in the country including installation of RTS on rooftop of houses. The minister also stated that in Gujarat out of total 261.97 MW installation, 183.51 MW are subsidised installations and 78.45 MW are non-subsidised installations. The minister’s statement also said that no formal study has been done to assess the quantum of power generated through solar panels installed at rooftops of the houses, but on an average it is estimated that 1.5 million units per MW per year are generated from solar rooftop units.
