However India's biggest capital good equipment company BHEL owned by the government is plannning a $500 million investment to build a solar cell factory in at Sakoli which is part Union heavy industries minister Praful Patel's constituency Bhandara.Talk about how dumb you can get. BHEL hardly has too much expertise in the solar panel industry and with solar cells in massive oversupply,it is almost sure to lose money. However that is how things work with Indian government companies where investment is made at the whims of ministers rather than rationality and business sense.BHEL is currently trading at one of the lowest valuations in its 10 year history and its not a big wonder why. The company has benefited in the past as did other machinery and engineering companies from an infrastructure invesment boom. However those glory days are over for the company as it faces competition from the Chinese companies and decreasing orders flow. Praful Patel the minister has already spent a few years in the airline ministry presiding over the conversion of the state owned carrier Air India ino a basket case. Now its the turn of BHEL to be turned into a basket case as well.

The Indian government is not going to impose any new duties on imports of Chinese solar cells. This is despite the petition by the Indian solar panel manufacturers to give a level playing field. Note Chinese solar panels have virtually destroyed the solar manufacturing industry in the West with big companies falling under the relentless price pressure where solar panel prices have gone down by 60% in one year. Only the Koreans seem to be standing up to the Chinese government backed top tier solar companies from China. The rest have mostly folded up and are facing survival questions including those from Taiwan. Indian solar companies were never that big and cost competitive anyway given the headstart and support of the Chinese backed companies. The price crash in 2011 has seen most of them close their factories as they can't even cover their costs at the Gross Margin Level.

JA Solar is the biggest solar cell producer in the world with more than 2000 MW of silicon cell capacity.The company has one of the lowest costs in processing of solar cells from solar wafers.The company is primarily a supplier of solar cells to most solar panel producers in Europe and Asia.However the sharp fall in solar panel prices in 2011 has resulted in most of the European companies shutting shop which has meant that JA Solar has faced a large loss in customer orders for its solar cells.Unlike its peer Trina and Yingli Solar,JA Solar does not have a good brand name or distribution of solar panels.It is more of a upstream supplier of solar products to solar comapnies rather than a end distributor of solar panels.JA Solar has diversified into making solar panels of its own and in partnership with other companies.Having a strong presence in the end market has become essential to survive in the cutthroad solar market.

What is a Solar Cell
A solar cell is an electrical device that converts light energy directly into electricity by the photovoltaic effect.Note Solar Cells can be made of many materials like Silicon,Cadmium Tellerium,CIGS and even on Organic Substrates.However almost 90% of the Solar Cells produced in the world currently are made of crystalline silicon.The drastic fall in prices of silicon solar cells has seen an explosive growth in demand with solar cell supply increasing by almost 50% per year in the last decade.

Multijunction Solar Cell Concept
The basic principle on which solar cells work is Photovoltaic ie. they convert the photons from the sunlight into usable electricity. However, in this process neither is all the light absorbed nor does all the photons get converted into electricity. High energy blue light photons do not have all of their energy converted into electricity, some is wasted as heat & low energy red light photons are not absorbed at all. Sunlight is made up of a broad spectrum and depending upon these various wavelengths, photons of light also have different energy levels.Hence, to minimize this wastage & to enhance the efficiency of solar cells, scientists came up with the concept of multijunction solar cells.

Solar Energy is the fastest growing industry in the USA and has been one of the fastest globally as well with solar demand rising by more than 150% in 2010 fueled by massive cuts in prices of solar panels especially those from China.While this has led to a major drop in solar energy stock prices this has also led to a massive boost in volumes due to demand elasticity.Only the top solar companies will be able to survive this brutal consolidation that is taking place with some companies like Solyndra already consigned to the death list.Solar Industry is a global one and has a big supply chain as well.This means that looking at only one stock market will deprive you of better opportunities that might exist in other stock markets.There is also a big supply chain associated especially with crystalline solar panels.There are companies that exist only in Polysilicon,Wafers,Cells,Modules.There are also companies that are suppliers of material like encapsulants and metal alloys to these industries.This article will give you a very broad idea on the complete list of solar energy stocks that exist in each part of the supply and different parts of the world.You can also look at the 2 solar ETFs that trade on the US stock markets TAN and KWT .

Dye sensitized solar cells are next-generation solar cells based on innovative technology. Unlike conventional silicon-based solar cells, dye-sensitized solar cells consist primarily of photosensitive dye and other substances. A dye-sensitized solar cell is a low-cost solar cell. This cell is also known as the Gratzel cell & was invented by Michael Gratzel and Brian O'Regan. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. It belongs to the group of thin film solar cells.

Solar Products in India are set to grow at a tremendous rate in the future driven by the declining costs of solar power and the increasing price of fossil fuel energy products.Already we are seeing massive power cuts across the country due to shortage of coal.Beside this,the prices of electricity has increased tremendously as well and is approaching seriously high levels due the increasing price of coal and gas.This has made it inevitable that people will turn towards solar products which are not only becoming cheaper but are also greener.Solar Products comes in a wide variety and range from almost all electrical home appliances.You can solar air conditioners,solar fans,solar toys etc.The main uses of solar products however are those in generating electric power .These are known as solar panels and poised to become ubiquitous in the days to come.The day is not far off when almost every house in India will have solar panels on their roofs to generate cheap electric power.Beside this solar lanterns are already replacing expensive and polluting kerosene lamps in poor households.Solar Lighting is also increasing particularly in those areas where the electricity power grid cannot reach.Solar Heaters have become extremely popular in southern India as solar water heaters are much cheaper than normal electricity powered water heaters.Though Solar Cookers have not caught on in a big way,there are also very cost effective and clean.Below is listed out the main solar products sold in India along-with their suppliers

Photovoltaic Cells have grown tremendously in the last few years spurred on by lowering costs and high demand in European countries like Germany.Photovoltaic Cell Manufacturers have also increased particuarly in low labor cost regions of Asia like China and Taiwan.In fact most of the solar panels have solar cells from companies in Asia.Solar Cell Manufacturers have incresased their capacity at a fast pace to meet the increasing demand.Currently due to oversupply of Photovoltaic Cells,the prices of solar cells have crashed with top quality solar cell prices almost 50% down from that one year ago.This is one of the best times to install solar cell panels in your roof given the rapid decline in the cost.Most of the independent solar cell suppliers are from Taiwan and some from China.European solar cell producers have mostly disappeared due to the high cost base of the European factories.

Solar Thin Film Companies are coming under siege again due to the relentless fall in the prices of crystalline silicon panels in recent months of 2011.Note large number of thin film companies went bankrupt the last time polysilicon prices fell off a cliff in the post Lehman crisis period in 2008 end.Applied Material the biggest solar equipment company killed off its SunFab Division which has a large customer list.Applied Materials saw the writing on the wall and concentrated its efforts on crystalline silicon equipment buying HCT Shaping and Baccini to become a billion dollar supplier of solar equipment.A number of weaker hands in solar thin film went out of business.However the prodigious growth in solar demand in 2010 saw large investments being made again.The biggest failure (not complete yet) seems to be the DOE and Obama darling CIGs startup Solyndra which has already used up a billion dollars with nothing much to write home about .Now Republicans are investigating whether the more than $500 million US government loan was done improperly.Abound Solar a CdTe startup has also managed a $400 million loan and I doubt whether it will manage to ever pay off the loan given that the lowest cost manufacturer of solar panels First Solar itself is under pressure from sharp cost reduction by integrated solar panel companies like Trina Solar.

Solar Power in India is set to be one of the biggest energy industries in the 21st century due to a unique set of favorable converging factors with declining cost the biggest one.The Indian government has recognized this fact and set a 20 GW of solar energy capacity target by 2022 and Indian states are boosting solar energy too through their own set of subsidies and solar supportive policies as well.However a number of problems have cropped up in the initial phases as solar electricity price is still high at Rs 14-16 unit compared to the retail electricity price of around Rs 4-5/unit.Though solar subsidies by the government should provide support till the prices come down.Major Indian solar companies like Moser Baer,Lanco are predicting that the solar electricity costs will fall by 40% or more in the next 3-5 years as technology improves,scale increases and more of the components like glass,solar inverters are manufactured domestically substituting expensive imports from countries like China and Taiwan.

Solar Panels have grown exponentially in the last few years driven by declining costs and growing energy prices.The advent of the low cost manufacturers of silicon solar panels from China,falling raw material polysilicon costs,subsidies from governements fighting climate change have all contributed to the more than 150% increase in world solar demand in 2010.Solar Panels are not only being used on roofs and giant rooftop ground plants,but also are being integrated in buildings known as BIPV applications.Solar Panels are also available in flexible forms which can be used in backpacks and other innovative ways.Now there is another niche for solar panels that is growing.Note most of these companies are using the Concentrated Photovoltaic Technology (CPV).The traditional CPV suffers from heating problems as high concentration of sun power leads to high temperature.Building the CPV systems on water will help them solve their problems according to these companies.

Note Big Oil and Gas has been slowly been retrenching form the solar energy industry despite initial leadership.Shell which was one of the biggest solar players has become almost non-existent while BP has shut down a number of solar factories outsourcing production to China.Other Oil and Gas companies like Exxon,Valero,Chevron and others have concentrated their energies on related green sectors like algae based biofuels rather than on solar and wind energy.So the move by Total comes as a surprise as it acquires one of the top 15 solar panel companies in the world.Sunpower is being acquired at a cheap price considering its world beating solar cell technology and its massive systems business which has gigawatts of solar projects under development.Note Sunpower makes the highest efficiency solar panels on a commercial scale and recently tied up with AUO.It is the 2nd biggest solar plant installer in the US and has a massive presence in the commercial and government sector.Total said it looked at over 200 companies before buying Sunpower.Note M&A has been strong in the Solar Thermal Industry and has now started picking up in the Solar PV Industry as well.With solar company valuations at a historic low,it makes sense for the larger chemical and energy companies to pick up good companies on the cheap.
