Sujoy Ghosh, Country head of First Solar India, says on solar energy has a place in the generation mix

    In the two years it has been in India, the American solar panel manufacturer, First Solar, has gathered as much mind-share as market share. The company has been in the news for both positive and negative reasons. On the positive side it is seen as an aggressive company that has quickly bagged orders from developers and EPC contractors.

Today, it has about a fifth of the market under its belt. The country’s first grid connected utility scale plant — Moser Baer’s 5 MW plant in Sivaganga, Tamil Nadu — has First Solar’s thin film panels. Recently, the company secured an order for 25 MW of panels from Green Infra, a sizeable order in the solar industry.
On the negative side, First Solar is seen as a company that has succeeded on the back of some aggressive lending by the US Exim Bank. Besides, the company’s Cadmium Telluride-based technology is frowned upon by environmentalists and its order book has been fattened by an ill-advised skew in the procurement policy of India’s largest solar programme. The National Solar Mission allows developers to import thin-film based modules, but mandates local procurement if they opt for crystalline silicon technology.

Sujoy Ghosh took over in May as the country head of First Solar India, which contributes 8 per cent to First Solar’s revenues ($2.8 b in 2011). Sujoy earlier worked for GE and Tata Honeywell. In an interview to Business Line, Sujoy speaks on the maths and myths of First Solar. Excerpts:

What is your order book position today?
Today, there are 225 MW of operating assets with First Solar modules. There are several more under construction by developers who won projects in Batch-II (of the first phase of the National Solar Mission), but I would not like to disclose the details because it is up to our customers to disclose them.
We now have about 20 per cent share of the Indian solar market and we will maintain the market share.

You have incorporated your company here. What is the idea?
When we entered India in 2010 —that’s the time National Solar Mission was taking off — we had a fairly satisfactory run of the market, in terms of selling modules to either third-party developers or EPC contractors — first to some of the ‘migration projects’ and then to Batch-I of Phase-I of the NSM and then Gujarat. Over the two years we have developed confidence in the Indian market that solar is here to stay. Solar has a space in the overall generation mix of the country.
What prompted us to open an entity is we want to build local capabilities on the ground and have a much broader relationship with the solar market in India.

Could you amplify on that?
Sure. When I say local capabilities — look at First Solar’s capabilities. We have the expertise to develop projects, do EPC, get financed, both on debt and equity, maintain those assets for the investors. The thing which we like about the development business is it helps to develop a pipeline. While the programme in India has been successful, it is lumpy in terms of demand. All the PPAs get signed on one day, everybody wants COD on the same day, decisions are delayed till the last moment, either on expectations of a drop in prices or to work through the documentation. This creates stress on the system in terms of people like us or EPC contractors who have to stock inventories and keep people on the bench, or let go of the opportunity.
For us as a company, our manufacturing process is continuous, unlike crystalline silicon. We are still the lowest cost manufacturer because we run out production lines optimally to full capacity to hit those cost points. If we run out lines only three months in a year we can’t.Therefore, it helps if we start developing our own pipeline of projects, it helps us to bring predictability of demand which then enables us to leverage our backend organisation — not just manufacturing, but system design and EPC and plan for building capacity as it comes. That helps us become more competitive.
That’s what prompted us to look at India as a key market. One of the five ‘sustainable solar markets’ for us based on their natural economic need, good irradiation or the country wanting to conserve their fossil resources are India, Australia, Saudi Arabia, South Africa and Chile — India and Chile because of the high penetration of diesel.
Our technology enjoys a good footprint in India and we want to broad base that relationship and get into a bit of development from our side, bring in our systems engineering expertise. A lot of these plants — the first wave of plants, either under NSM or Gujarat — have been built, in a lot of cases, by EPCs who don’t have much experience in doing solar. Yes, there have been a lot of European EPCs who have plenty of solar experience in terms of building assets, but there have also been an equal number of home-grown EPCs who have come in and built plants.
I think asset quality in some cases might have been compromised. Fifty per cent of the cost of energy is the funding cost. I think, as a stakeholder in the industry, it is our duty to make lenders comfortable with the asset. Only then will they lower their risks and only then will we see good quality capital. Right now, many of these projects have been built with recourse to the balance sheet. That is not really project financing. For Indian banks, ‘will it work’ is the question that they want to see because there is not much record of generation. Large Indian lenders, for instance PFC and REC, who lend to other parts of the power sector, have not really got into solar and unless that happens you cannot sustain an industry in India.

Do you organise funding for your customers?
Our customers have been able to organise finance, a combination of local banks and foreign banks, we are not privy to the nature of the …
There is an impression that you have been successful in India because of the backing you have received in the form of low-cost financing by the US Exim Bank.Well, first of all, US Exim is not captive to First Solar — there are other US manufacturers in the market besides First Solar.
The other thing is — while I am not sure about the exact percentage — a majority of our 225 MW is not financed by US Exim. The number of projects financed by US Exim is probably a third.
The point is, we are selling because our technology, at least in hot climatic conditions, produces more power than polycrystalline silicon.
We hear very divergent views on that.
See, it is like this. Our nameplate efficiency figure is about 12.7 per cent. The poly guys maybe at 15.5 to 16 per cent. The mono crystalline may go up to 20 per cent. All these efficiencies are at ‘25 degrees C, one atmosphere’ conditions. Now, each manufacturer publishes what is called a temperature co-efficient. The degradation curve — as your ambient temperature rises, your efficiency will fall. For the First Solar modules, that degradation is 0.25 per cent per degree rise in temperature. For the average polycrystalline, it is 0.45.
So, as the ambient starts hitting 40 and above, our modules start producing more. This is ambient 40. Typically, the cell temperature is 15-20 per cent higher than the module temperature. FS modules typically produce 8-10 per cent higher energy under high ambient conditions.
The second thing about thin films generally is that the impact of diffused sunlight —cloudy conditions, or dusty conditions — that causes poly output to drop further, compared with TF. India is a combination of high ambient and diffused. So generally we find that we get a higher energy yield in India. That’s been fundamentally the reason for our success. That helps to lower the LCOE (levelised cost of energy).
Thin Films, in general, and First Solar panels, require more space. But the incremental cost of land is outweighed by the incremental yield

In how many months in a year in India would the temperature be higher than 40 degrees?
Rajasthan and Gujarat practically nine months in a year.
First Solar modules are best suited only for these states then?
In other places, even if the ambient temperature is lower, the cell temperature is 15 per cent higher. If the ambient temperature is 35, then the cell temperature is 50. I am saying, at more than 40 degrees our panels start producing more electricity.
The other impression going around is that thin film has a market in India because of the skew in Government policies (that permits import of thin film modules, but requires crystalline silicon modules to be made here.)
In Gujarat there is no such policy lacuna. The National Solar Mission was 150 MW, and Gujarat was 600 MW. We got more share in Gujarat than in NSM competing against Chinese companies.
I think people have bought us primarily because of our yield performance. Second, they see First Solar as a profitable company. In projects that are financed on non-recourse basis, the lenders demand a great amount of due diligence and look at the solvency of the supplier for enforceability of guarantee and warranty obligations.
True, US Exim has indeed helped people who have bought from us. But then exim financing is available from other countries too. Exim is not a captive product of the US. Exim is an enabler, but people first make a technology choice. If they go for Chinese technology, they have access to the same level of funding from the Chinese banks. It is unfair to say that the only reason why we are successful or we got this kind of installed base in India is because of EXIM.
Some experts say that thin film modules made sense when the price differential between thin film and crystalline silicon was large. But now the delta is so small and hence thin film modules do not make sense.
That argument is absolutely correct under temperate conditions and rooftops. Because you end up paying higher price for ‘balance of system’ for marginally higher price of the modules. But because of the yield and because of the diffused sunlight and relatively low cost of land in the overall economics of the project, there is still a significant amount of advantage that the thin film brings.
The other point that we must remember is that crystalline silicon pricing seen in the market today — in our view and as is evident from the balance sheets of the companies — they are selling below their manufacturing cost. So, the question is whether this cost is sustainable.
So, you have the balance of systems penalty for TF and the higher yield advantage. Net-net, thin film is still advantageous.

Within thin film, do you think your Cad-Tel technology will continue to rule the market?
Within thin film, we have CIGS, Cad-Tel and amorphous silicon. I don’t know whether you are aware or not, First Solar was also looking at CIGS, very actively, trying to build an alternative technology. The cost of CIGS in our view is at a point that it will take them a long time to catch up with us.
It is one thing to say ‘we have hit a certain efficiency level in the lab’ and quite another thing to say ‘we are bringing such efficiencies on a sustainable basis in our production line’. That’s a considerable gap.
Second, are the efficiency levels (claimed by CIGS manufacturers) bankable? How much data do you have to back that efficiency? Any lender will say, you have reached that efficiency in the lab, fine, but show me where it is working.
Crystalline guys would then have the same argument against you? Do you have the same performance data as they do?
Why, we have performance data for 16 years.
In India?
In India also we have data. In India, even the crystalline guys have date only for two years, because the grid-connected plants are only two years. Off-grid is not a real measure of efficiency.

What about amorphous silicon?
In today’s world any new breakthrough technology requires a lot of money to scale up commercially. The incumbent technology people will also continue to improve their technology. Even we are working on our technology to improve our efficiencies. It will be incremental.
On the poly side, you put in more material you will get more efficiency. If you scan the global solar scale, you might see a lot of interesting concepts. But if a company like GE, which was pursuing its own solar programme gave it up, I’m sure other smaller players will find it very difficult.
Thin film is really about the manufacturing process. How you lower your rejection rate? How you are able to consistently produce the same module-after-module, deposit the same material in the same way so that you get the same results? It is about consistency in the process. It takes considerable amount of time before you hit that. Till you hit that there is a lot of rejection.
We have passed that point. Relatively we are pretty stabilised.

Is the market then a blue ocean for you?
I am not saying that. It is not a blue ocean. India has got other challenges. We are just discussing technology. I think from a technology standpoint we have got certain advantages when it comes to utility scale solar. That’s one dimension.
The challenge is our competition pricing their products at probably below cost. I think the bigger challenge, as these programmes get built in India is about ‘will this policy sustain’? Will the grid keep pace? You can build a solar plant, but you do face grid congestions.
Finally, solar has to reach a point where wind is today, for it to be really sustainable. Pricing of power, cost of power from that aspect, has to be something where you need a FIT (feed-in tariff) to keep the wheels turning. As an industry, all of us are trying to look into that point. Because all of us do believe there is a shortage, and if we can bridge some of the gap — it may not be huge in energy terms — people might be willing to pay a higher price because right now the alternative is no power.
Do you see a situation where for a want of funds for FiT, the industry is pushed to only bilateral PPAs?
The National Solar Mission is going to be there. The Government has made a commitment.

But where is the money for NSM?
Look at it this way. The average price of Batch-II was Rs 8.50. The average HT price is at Rs 6 — and in the southern states even if you pay the price you get power for three days a week. So, there is a demand. Question is, are people willing to pay more for the demand? Second is, how much are they willing to bet on the future price of coal. Solar is a good hedge against that, because fuel is free.
A lot of us in the industry are trying to discover a demand outside of FiT. But at the same time I think the NSM will be needed to give scale. Indian industry needs to scale up. For that, both forms of programmes (FiT and bilateral PPAs) need to co-exist.

Who is going to pay for the FiT?
Today, the gap between the price of conventional power on the higher end and the price of solar power coming from FiT is not that big. The differential has come down. You should intuitively believe that coal prices should go up. Who predicted coal prices will be $140 a tonne. That’s where you hit the grid parity point.
The question is, even if grid parity happens, will it uncork large demand? Just by doing grid parity, it may not. You need other things such as open access, how you are going to wheel and bank this power … really the grid and the grid operator being comfortable with this kind of power coming in. The solar assets which one creates also need to have features that make them dispatch-able.
We are building assets such as a 550 MW A/C in the US. These are large chunks of power coming into the grid. There is a well defined grid code which we have to install in the design of the solar plant which will make this power-grid-friendly.
I think as the plants in India, NSM Batch II come up, people will begin to see some of those features being installed. Same like wind. From the 250 kV class machines today you have 2 MW class machines. A 2 MW machine has got a lot more features in terms of voltage ride-through, voltage control, and some of those features which allow the machine to not go off-grid when there is a grid disturbance — it rides through the disturbance.
A solar plant is also similar in nature. In wind you have what’s called a converter. In solar it’s an inverter. It’s virtually the same thing. What these Government programmes will do is, to help people to scale, demonstrate that the power can be integrated into the grid properly, which will give confidence.
Bilateral deals will happen, but again, we will not see bilateral deals such as 100 MW happen in year one. People will test the waters. Even if I have a PPA — even if I am generating, who is assuring me that the grid is available? That’s where in this whole ‘bilateral deals’ we will still have to figure out how to take the grid companies along with us.

So you still continue to depend upon these Government-sponsored programmes?
We need both. I am saying that while the Government programmes are important to scale…
Look at it this way. We’ll see probably the first few deals happening on bilateral basis. If it works, I am sure there is enough demand for people to move into these bilateral deals.
Today it is not about the appetite to take power — there is the appetite. There is appetite to put the assets up. The key is really the grid.

What are First Solar’s ambitions in India?
Our goal is to see if we can create a pipeline which is predictable enough for us to then figure out if the Indian market is mature enough for us to put in manufacturing operations here.

How do you intend to create a pipeline?
By developing our own projects. We are in discussions. As you would recognize, when we do development … development and EPC construction requires a lot of local expertise. We do believe that in India there is enough local expertise available already.
So what we are trying to do is to structure partnerships. Like: you got local developers who want to build projects. First Solar is here. We’ve got the technology, got the experience to do this. We know how to put a quality asset together. We also have some leverage in terms of financing. So we are trying to put our combined expertise together instead of recreating competencies.

Does it mean that you will not own the assets?
We ideally would not. We are not an IPP. We are a technology company. What we want to do by development is really try to enable a pipeline.
Are you going to adopt the ‘wind model’, where a manufacturer puts up a wind farm and then sells slices of it to investors or IPPs?
We are trying to make that a model. The challenge for us, unlike say Suzlon building a farm, is the price of power. Also, the Suzlon model was built around ‘accelerated depreciation’. Whereas what we are trying to do is to enable more solar energy coming into the grid. Slight differences, but in the end the model remains same.
We want to create the assets and then ultimately transfer the ownership to somebody who wants to own it long term and then have an O&M agreement so that we deliver our performance for as long as the guy wants to be comfortable with the asset. This is what we do in the US, Canada and elsewhere.
At what stage is this thinking?
It would be premature for us to disclose to plans, but we are looking at States where there is good solar irradiation, and States which have good demand. Bilateral PPAs make more sense in South India. Currently, that is where the power constraint is more. The Southern grid is starved of energy. The bilateral PPAs will immediately make sense here.

What are your major concerns?
The big question mark is the enforceability of the RPOs (renewable purchase obligations). It has not really happened, even if it happens in the industrial sector —because in energy terms they are a big consumer — if you start enforcing it across discoms, how are you going to monitor, there is not enough monitoring capacity available — even if you enforce it on a limited scale on the industries, I think that will give a fillip to the market. REC/RPO is a good programme, but without enforcement it has no meaning.
We are in the initial development stages with some partners, looking at land options, looking at how we get the optimal PPA pricing and as soon as we sort out some of these things we could probably begin construction.

Will the removal of accelerated depreciation for wind power developers work in your favor?
There is some interest from some of those who have AD appetite, but to my knowledge no deal has got closed. But remember, these AD customers will start placing orders in February. So, it is early days yet.
What is your take on the manufacturing in India? Should the Government mandate local procurement or not?
Our view, as a developer, is that there should not be any restriction on their ability to source stuff. For the manufacturers, it is a function of predictable demand — solar manufacturing is all about scale. Also cost of power, cost of utilities in India is extremely high. We have to really see what kind of incentives Government is giving to people who are putting capital. That is secondary. The biggest issue is, is there enough scale domestically created which can justify manufacturing at the same time not impact the developers.
Because, if you set up a smaller scale manufacturing plant…globally there is over capacity. The solar developer community is trying to lower the cost of power so that it creates more demand, and at this point in time if you impose restrictions on them, saying they have to source only from domestic, they lose the advantage.
Therefore, it is a function of a) on the front-end, how do you create scale, which will come if policies are consistently enforced. Enforce RPO, you immediately create a market. If it is a natural economic need, definitely people will come and put up manufacturing. We cannot have and should not have a policy where you restrict the ability of the developer to bring to you the lowest cost of power. If you do that, if cost of solar power goes up, it is going to shrink the market, and it will be a non-starter. It will have exactly the opposite effect of what you are trying to create.

Do you think there is scope to bring down costs outside modules, say, in Balance of Systems?
I am not an expert on that subject, but here is what I would say: the amount of cost focus that has been there has not been there on the BoS front. But at the same time, remember, the BoS has got like fifty different components.
Take the biggest — the inverter — is there a good scope for cost reduction?
Even if you take 30 per cent cost of the current inverters—inverter is like 2 cents per watt in an overall project cost of, say, $ 1 .75. It is not going to make much difference.
But the module is only 50 per cent of the overall cost. In some cases it is just about engineering, more than taking cost out — things such as structures. In the first wave, the good ones, the EPCs mostly came from abroad, because there was no Indian. They adopted the global designs to do the first level of projects. People have learnt from that.
The Indian EPCs looked at their experience in non-solar and built something. They have learnt from that. The way you do electrical systems, foundations etc. There is scope to take BoS costs out, but a lot of it is about how you engineer the plant and get more efficiency around engineering—how do you design the plant for Indian conditions. People have learnt a lot.

What would you say about the high warranty claim reserves set off by your parent company?
Any semi-conductor material which goes into higher temperature will experience more abuse. It is physics. What we said was historically 90-95 production used to go to temperate climates. Over the past few years, India had about 8 per cent of our global revenues; we are building a lot of plants in the US in very hot conditions. What we said was as our demand changes from 90-10, to exactly the opposite, we will have more warranty reserves, because we could naturally expect some recall of projects, because of the more abusive conditions. That’s all to it.

Indian Solar Summit 2013

With aims to accelerate the number of solar installations in the country to reach a target capacity of 30GW by 2017, India has established itself as one of the most attractive renewable investment markets in the world.

In order to make this target a reality, India’s premier solar show – The Indian Solar Summit and Exhibition – is back in 2013.
Start Date : 18th April, 2013
End Date : 19th April, 2013
Place : Mahatma Mandir Convention Centre, Gujarat

why solar ???


        Since the earth was born every natural object transforms its steady state into the non-steady state by reducing its energy. Tree grows up by acquiring energy from its surroundings in the form of water, sunlight and minerals. Animals intake that energy by eating products from those trees. In this way all the living things are dependent on surrounding energy stock which is mainly provided by the sun. Yes, except the geothermal energy all kinds of energies are drawn from the sun.
       Due to the pressure difference created by the solar radiation, wind is generated. All types of Bio fuels are developed by solar energy, all conventional energy sources are older forms of solar energy (as they are made up of buried vegetation, animals with some amount of minerals mixed with them). So any form of energy that we are using these days are, ultimately, products of solar energy. 
Then why not use it in the direct form and make the world a better place to live in? :)

Azure Power (Gujarat)


 

Three solar power companies are in a legal tangle with the Gujarat Government over the issue of ownership of the companies that are putting up the projects. All the three – Azure Power (Gujarat), Millennium Synergy and ESP Urja – are wholly owned by American solar power developer SunEdison.
The point under dispute is whether or not these three companies are in breach of a covenant of the power purchase agreement which stipulates that the “power producer shall continue to hold at least 51 per cent of equity from the date of signing of this agreement”.
Azure Power (Gujarat) and ESP Urja have a 5 MW plant each, while Millennium runs a 10 MW plant.
Gujarat’s nodal agency Gujarat Urja Vikas Nigam Ltd had issued notices terminating the power purchase agreement for Azure Power (Gujarat) and had stopped making payments for the purchased power for the other two companies.
Azure Power (Gujarat) was initially promoted by Azure Power India, a company whose various projects have been funded by the German development finance agency, DEG, the US Exim Bank and IFC (Washington).
The three companies have petitioned the Gujarat Electricity Regulatory Commission. The Commission, in its orders passed recently, has stayed the operation of the termination notice served on Azure Power and has directed GUVNL to make the due payments to Millennium and ESP Urja.
“It is unfair and unjust that the generator is not paid for the power supplied by him to the distribution licensees,” the order says.
In the case of Millennium and ESP Urja, GUVNL had raised the issue of compensation to be paid by the project developers for any violation of the PPA covenants. But the Commission dismissed it saying that was “not a subject matter of the present petition.
”The IFC-funded SunEdison’s contention, as spelt out in the order relating to the Azure Power case, is that it signed the shareholder agreement – for taking over the ownership of the developer – prior to the signing of the PPA.
The question as to whether or not there is a breach of the PPA with respect to the covenant relating to the shareholding pattern is yet to be decided by the Commission.

solar vs wind

As the world continues to search for the best renewable energy resources, two sources continually come to the forefront: solar and wind. Although both of these sources are considered to be environmentally friendly, there are pros and cons to be aware of.
Wind Energy
In many parts of the world, wind power is available in abundant amounts. Along with this, it is 100 percent free. Areas that are clear of obstructions (such as the United States plains), close to the shoreline, or at a higher altitude make a better fit for wind energy.
Pros
  1. Wind energy does not release any pollution into the air: Along with this, it does not contribute in any way, shape, or form to global warming – except in their manufacture. When you add the fact that wind turbines do not consume any water, it is easy to see why this is at the top of the list in terms of alternative energy sources.
  2. Wind power does not cost a dime: In short, it is clearly one of the best renewable sources of energy as it is considered inexhaustible. In other words, there will always be wind. There is only so much oil and coal in the world. Along with this, it must be extracted from the earth which costs a lot of money. On the other hand, wind turbines can continuously harness the endless supply of kinetic energy derived from wind.
  3. A great source for local jobs: From construction of wind turbines to daily maintenance, as the use of wind energy increases more and more local jobs will be created. With the unemployment rate rising and no end in sight, any jobs created by this form of energy should be considered a huge benefit. Additionally, wind resources are often located in remote areas that are already at an extreme economical disadvantage. Bringing wind power to these areas can provide steady revenue to local communities including land owners and farmers.
Cons
  1. Not a reliable source in all parts of the world: In short, this form of energy is only efficient when there is enough wind to power the turbines. As you can imagine, there are many parts of the country that lack the necessary wind force.
  2. Wind farms are unappealing to the eye: Do you enjoy driving down the highway, looking off into the distance to admire the view? Well, this could come to an end, to a certain extent, as more and more wind farms are built throughout the world. Although beauty is in the end of the beholder, some feel that wind farms are nothing more than an eyesore.
  3. Land is expensive: One of the biggest costs associated with wind energy is the land on which the turbines will be constructed. Not only will this land need to be purchased or leased, it is often times more expensive in the areas (such as coastal communities) in which wind power is most effective.
Solar Energy
Over the past five years, solar energy has become more and more popular. This holds true both among commercial and residential properties. Although there are many benefits of solar energy and this appears to be the wave of the future, there are disadvantages holding back mass production and installation.
Pros
  1. No pollution: For some, this is the clearly the number one benefit of solar power. Solar panels give off no pollution. The only pollution produced is the direct result of the manufacturing process.
  2. The sun is an endless, clean supply of renewable energy: As long as the sun continues to shine this form of energy will do its job. On the contrary, finite fossil fuels, such as oil and coal, are not going to be around forever.
  3. Saves money in the long run: There is no denying the fact that solar panels can be an expensive upfront investment (more on this below). That being said, this source of alternative energy can save you money in the future. Since you are using less energy, your utility bills will be much less. In some cases, you may not owe any money at all.

Cons
  1. Cost of installation: As noted above, installing solar panels on a home or commercial property can be very expensive. This is a large upfront investment that is not affordable for everybody. However, if you can afford the initial cost you will more than make your money back in the long run thanks to smaller or non-existent utility bills. Generally speaking, the cost of a residential 5-kW system is approximately $35,000 depending on your location.
  2. Aesthetics: Are you aware that solar panels can take up a lot of space on your roof? For this reason, they are often times eyesores that homeowners are not willing to deal with. This is one of the biggest drawbacks because there is no solution.
  3. Not efficient for around the clock use: Solar panels only work when the sun is shining. When the sun goes down, you are forced to rely on stored energy from the panels or an alternative system. In turn, this could result in a small utility bill every month.

Veer Energy Buys New Millennium Solar Panels for India Project


Veer Energy & Infrastructure Ltd. (JHI), a Mumbai-based wind-power developer, bought solar panels for its first project in India from U.S.-based New Millennium Solar Equipment Corp.
Veer plans to install 400 thin-film panels of 58.5 watts each for a rooftop project in the Sanand district of the western Indian state of Gujarat, the company said in a filing today.
It will be Veer Energy’s first solar installation. The company, which plans to pursue larger megawatt-sized projects after this pilot, expects to earn an additional 20 million rupees ($374,111) profit in the year to March 31, 2014, from its solar business, it said.
New Millennium Solar was acquired in September 2011 by Sunlogics Inc., a Rochester Hills, Michigan-based company backed by General Motors Co. (GM) Sunlogics has changed its name to ViSole Energy Inc., according to its website.

A grid connected pv system

Size of the PV generator
The economically optimal size of a grid-connected PV system  depends mostly on different financial incentives and legal parameters, since grid parity - meaning the costs of photovoltaic generated electricity are equal to or cheaper than the price of grid power - is achieved only in a very few regions today.Net metering concepts, as they are widely in use in the US and Canada, provide - like with stand-alone systems - no incentive to build systems that generate more electrical energy than consumed at the same estate during the year; the grid replaces only a local battery storage. Feed-in tariff systems on the other side render big systems with net excess profitable.
A PV system may cover the whole roof; the pictured solar roof (233 square meters) has a nominal power output of 24,2 kilowatt (kWp). Picture: Hieronimi regenerative Energien GmbH

- Required module space:
Within bigger systems mostly crystalline silicon modules are used today. To install a nominal capacity of 1 kWp (Kilowatt Peak) with such modules and area between about 7 m² (using monocrystalline cells) and 10 m² (using polycrystalline cells) is required. Otherwise unused pitched roofs are in many cases the most cost-efficient places to install a PV system, especially if they are oriented to south and inclined to a degree of about 30° to 37°.

- PV Orientation and Output
The efficiency of the photovoltaic process is at its highest if the sun rays hit the panel vertically. Therefore PV modules should be oriented to south (speaking of the northern hemisphere) and somewhat inclined; the optimal inclination angle depends on the location (including latitude, altitude and other factors). As a rule of thumb the inclination angle would be best between 3/4 and 4/5 of the latitude – resulting            in angles of 32° to 38° in Middle and Western Europe or 30° to 36° in most of the US. However: Small divergences from the optimal orientation and inclination result only in even smaller reductions of energy output per year.
In order to most effectively use Solar Radiation, a PV Module or Collector of a photovoltaic system and Solar Heating System, respectively, is aligned to absorb or collect as much of the radiation as possible. The radiation's angle of incidence, the tilt angle of the module or collector, and the azimuth angle all play roles in achieving the greatest possible power production.
The azimuth angle (β) in the picture at right) specifies how many degrees the surface of the module or collector diverges from the exact south-facing direction. The tilt angle (α) specifies the divergence from the horizontal.
Experiments show that photovoltaic systems operate most effectively with an azimuth angle of about 0° and a tilt angle of about 30°. Of course small variances in these values are not at all problematic: with the system oriented towards the south-east or south-west, about 95 % of the highest possible amount of light can still be absorbed. Large systems with arrays are fitted with electric motors which track the sun in order to optimize output.

- Power inverter:
PV systems provide direct current (DC) voltage. To feed to the grid, this DC voltage has to be inverted to the grid alternating current (AC) voltage by a »mains-commutated« or grid-tied inverter, synchronizing automatically its AC output to the exact AC voltage and frequency of the grid.
This MPP fluctuates during operation in an interval depending on the radiation, the cell temperature and the cell type und has so to be tracked by the inverter controlling unit.
The second important job of the solar power inverter is to control the PV system to run near its Maximum Power Point (MPP), the operating point where the combined values of the current and voltage of the solar modules result in a maximum power output. This MPP fluctuates during operation in an interval depending on the radiation, the cell temperature and the cell type und has so to be tracked by the inverter controlling unit.

experts view on rooftop solar panel by MAHESH BHAVE & DEBASHIS CHATTERJEE

With will and vision, India’s energy prospects can be changed from grim to green, and the world will benefit as a result.
The failure of the country’s electricity grid on July 30 and 31 highlights its vulnerabilities and underscores a larger national need: about 400 million Indians are not connected to the grid at all, and those who are have unreliable access. At 571 kWh per capita, India’s electricity consumption is one-fifth of China’s (2,631 kWh) and less than one-twentieth of the US’ (12,914 kWh). India’s electricity demand will only grow.
Burning coal for electricity is increasingly expensive, causes global warming, and jeopardises the planet’s health. In any case, India has ash-rich coal, limited oil, unknown amounts of gas, poor mining productivity and inadequate transport. Power plants struggle to get reliable fuel supplies. Solar electricity today at Rs 7.50 a kWh is economical compared with subsidised diesel-generated power at roughly Rs 15 a unit, but more expensive than coal-based electricity at about Rs 6. What, however, is the true cost of coal-based power? Prices are distorted by subsidies, State boundaries, vote-bank politics, and uncharged carbon-emission costs. Average prices matter less than peak prices. When India sheds load to manage peaks, customers use expensive diesel power.

Universal access

How do we come out of this energy and infrastructure bind? Nothing short of a fundamental re-imagining, starting from first principles, of all energy solutions is essential to address India’s energy needs. Can India leapfrog into a clean-energy future rather than extend the conventional grid with fossil fuels at its core? In a nation blessed with abundant sunlight, to what extent should electricity be a networking service at all? Could India tap ambient solar energy for most of its needs?
India’s single-minded focus should be massive and rapid solar deployment, not only through utility-scale solar plants, but also through distributed generation, household-by-household, nationwide. Electricity in Indian homes should be rooftop-to-room and solar based with energy self-sufficiency as the goal; the grid can complement and serve as back-up where available. Much as TV antennas once sprouted on rooftops, so should solar panels.
Public policy should have a singular aim: universal electricity access.
By implication, policies aimed at encouraging domestic manufacturing, local content requirements, or favouring one technology over another should be put aside as tertiary.
The aim should be personal power just as we have personal computers. Slowly, we will get there. In the meanwhile, solar electricity is poised to become a friendly, industrial scale, cottage industry, like vegetable patches in home gardens. Photovoltaic technologies have matured sufficiently and present us with simple, affordable electricity alternatives to the traditional grid.
Enabling public policy can unfetter entrepreneurial energies and give birth to millions of small and large solar-related businesses, and thereby generate employment. Distributed solar generation can spawn innovations. Standardised 1-kW solar kits, for instance, can be mass produced and installed easily. The household deployments can extend to communities and neighbourhoods resulting in self-sufficient micro-grids.

Partnership with China

Community micro-grids for tens and hundreds of households in villages, towns and cities should be India’s preferred electricity infrastructure. Anchored with solar, the solutions may include combinations with bio-diesel, batteries, wind, biogas, micro-hydro, etc. At night or when the sun is behind clouds, alternative yet local sources can assure electricity. Once solar energy takes root, India will need less of the colossal and wasteful transmission, distribution and generation infrastructure except for industrial operations such as running factories and trains.
China has recognised the importance of solar energy and invested in numerous solar-panel factories. Taiwan is doing the same. Due to the manufacturing excess, prices have dropped by over 70 per cent in the past three years, and the fall continues. India presents a ready market for that production. The formula, ‘China produces, India deploys’, makes for a winning partnership.

Moral Imperative

Among competing national priorities, what can be more catalytic of overall welfare than universal electricity? It can extend working hours, reduce pollution and diseases, and help prevent food waste. Beyond lighting homes, solar solutions allow for the spread of the Internet and therefore education, e-governance kiosks and ATM machines.
Solar panels facilitate a parallel infrastructure for clean transport — charging batteries for electric bicycles, scooters and cars. Solar energy aids cooking, powers streetlights, operates irrigation pump sets and substitutes diesel burning for cellular towers. Stubborn problems such as efficient battery storage persist, but they can be dealt with as the market evolves.
The grid failure has crystallized the solar market. There has never been an India-sized market for solar electricity, with relentlessly rising demand, talented people, old infrastructure and plentiful sunlight. The scale can establish new low-price benchmarks and thereby aid the entire world. Unfavourable economics has been the primary barrier to the spread of solar energy until recently, but no longer.
Universal electrification is a human-rights, inter-generational-justice and human-capital-growth issue all in one. For how many decades should a third of India’s citizens use kerosene for light and cooking, children study by smoky, unhealthy flames, and income-earning opportunities fade with sunset?

Ahmedabad Municipal Corporation ropes in IIM-A startup for LED streetlights

AHMEDABAD: The Gandhi bridge in Ahmedabad will soon get eco friendly streetlights, courtesy a venture by an Indian Institute of Management, Ahmedabad (IIM-A) alumni.
IIM-A alumnus Akshat Khare and his partner Dhaval Shah, a Nirma University graduate, through their startup-Nessa Illumination Technologies, will run a pilot project on Gandhi bridge by replacing 10,000 conventional street lights with LED lights.
Ahmedabad Municipal Corporation (AMC) spends about Rs 12-15 crore annually on external lights in the city. Our business model will help them save up to one-thirds on electricity bills. Besides, the lights are maintenance free, which will help them cut additional costs," said Khare, director, Nessa.
The startup will run the pilot project this month. Instead of paying the entire cost upfront, AMC has the option to pay from the savings on electricity bill. According to the company, any organization that installs the LED lights and solar solutions can see pay backs within a year of installation.
Nessa has also sold solar products to the 600 MW solar power park in Gujarat, promoted by chief minister Narendra Modi as Asia's first and largest. Nessa has also replaced 150 watts sodium streetlights with on IIMA campus with 60 watts LED streetlights.

Bosch Solar, a unit of German company Bosch, will soon electrify villages in India. The €788-million solar division of Bosch has implemented a micro-grid based solar power project of 5 kW at a village in Bihar, jointly with NGOs, and is working on more such rural electrification projects in Maharashtra and Tamil Nadu, said Mr C. M. Venugopalan, Sales Director, Solar Energy Division at Bosch Ltd.
The pilot project (funded by Bosch’s solar division) in a local market in Bihar’s Tamkuha village supplies about 15 units of electricity everyday, powering over 50 shops, the company said. Bosch entered the solar energy segment in India in June last year. It is present across the value chain and manufactures silicon, ingots, solar cells, and modules, besides executing power projects.
Rural electrification apart, Bosch will focus on executing commercial and industrial rooftop solar solutions in India.A certified partner of the Ministry of New and Renewable Energy, the company can get the Ministry’s 30 per cent subsidy for rooftop projects, Mr Venugopalan said.
“The company is in the final stage of executing a few such projects in Gujarat of about 100 kW capacity,” he said. The company also provides EPC (engineering, procurement and construction) services where it designs, procures equipment and sets up plants for power project developers. Bosch Solar has executed a one-MW grid-connected solar power project in Gujarat, and also expects to “set up a couple of more 1 MW-scale projects in Gujarat, Maharashtra and Rajasthan by the end of this year,” Mr Venugopalan said.
For the grid-connected power projects, the company would have some projects under the Renewable Energy Certificates scheme, Mr Venugopalan said. REC scheme is one where producers of renewable energy that opt out of the preferential feed-in tariff get tradable certificates.

chhattisgarh's rural electrification story

A Chhattisgarh government initiative has succeeded in electrifying many remote villages with solar energy where other states have failed
Around 50 villages in Chhattisgarh’s Barnawapara Wildlife Sanctuary, that are not connected to the national grid because they are in a remote area, have been enjoying the benefits of electrification since 2003 under the Remote Village Electrification Programme of the Union Ministry for New and Renewable Energy (MNRE).
The four-kilowatt solar power plant that provides seven hours of electricity every day to all 75 households and lanes in Deba village, in the Barnawapara Wildlife Sanctuary, for instance, generates 28 units (1 unit=1 kWh) of electricity a day.
The technology for such projects is simple and the source of power abundant, making it the obvious choice for electrification in rural areas. Yet solar off-grid projects under the programme have not been as successful as expected across the country. Chhattisgarh is an exception with 1,400 solar-powered villages.
The failure of the system is said to be due to poor maintenance and lack of monitoring. Equipment has been stolen or is lying defunct in several states. In Kalahandi district of Orissa, for example, the government installed solar home lighting and street lighting systems in 40 villages in 2009. A survey by Desi Technology Solutions, a consultancy firm in Bhubaneswar, reveals that the system in 30 villages became defunct within a year.
Chhattisgarh experienced much the same problems initially. In 2003, the Chhattisgarh Renewable Energy Development Agency (CREDA) installed solar home lighting systems in 500 villages. The system is an assembly of solar panels, cables, an inverter, a battery and two 11 Watt CFLs.
“Half of the panels got stolen within a year. Some (people) even sold them or mortgaged them for money,” says S K Shukla, director of CREDA. A survey in 2004 showed that of the 617 solar modules installed in tribal hostels, ashrams and primary health centres, 500 were stolen. And so CREDA opted for micro-grids.
A solar module of 37 W costs Rs 14,000. With the 90% subsidy provided by MNRE, each module costs the state Rs 2,750. Compare this with the cost of setting up a micro-grid (solar photovoltaic power plant and transmission cables) per household, which is approximately Rs 25,000. The state shells out about three times more for a micro-grid than a solar home lighting system.
“Micro-grids require more investment from the state exchequer because the subsidy by MNRE is limited (90% of the installation cost or Rs 18,000, whichever is more). But they prevent theft and require minimal maintenance,” says Shukla. CREDA organisation installed the first micro-grid in 2004.
CREDA started electrifying villages in two ways. Micro-grids were installed in big concentrated villages (of the 1,400 solar-powered villages, 500 have micro-grids of a total installed capacity of 2.35 MW, providing electricity to over 35,000 households), while in villages and hamlets where houses are scattered solar home lighting systems were installed as it was not feasible to invest in wiring over long distances.
The problem of maintenance remained and to tackle it CREDA envisaged a three-tier system: a local operator from the village to carry out simple repairs and clean the solar modules, for which he receives Rs 5 from every household; a contractor appointed by CREDA who employs technicians to service a cluster of 10-15 villages and carries out regular servicing of batteries and invertors and more serious repairs; and CREDA itself. The contractor-appointed technician files a monthly report on the status of all the work he has done and is paid Rs 25 per household per month by the state government. CREDA monitors all installations through the monthly reports and replaces faulty equipment.
The system works well when the demand for power is limited. If villagers begin to use TV sets and other electrical equipment it proves inadequate. Under the programme, a 37 W solar system is provided to a family, which does not even meet the minimum electricity requirement of 1 unit a day mentioned in the Electricity Act. 
Despite this, demand is growing in the state of Chhattisgarh. A solar power distributor in Sarguja district says sales have increased almost five times in the past seven years -- from Rs 15-20 lakh in 2004 to Rs 4 crore this year. Solar power is not used only in remote areas but augments grid power too in many places.
Solar power is clearly a viable option to hasten the electrification of India without involving environment-destroying and capital-intensive costs. How well governments use it remains the crucial question. :)
