.The cost of the solar panel can also vary a lot depending on the retailer,size of the solar panel,technology and the brand.This makes buying solar panels a confusing problem though most residential and commercial buyers are not involved leaving the decision to the solar installer/EPC company.The advent of Chinese solar panels has made the Western and European solar panel companies lost marketshare rapidly.In fact most of the European companies are shutting factories to open plant in Asia where the costs are much lower.Japanese solar companies however continue to keep their manufacturing in developed countries as they get a premium for their solar panels which are considered of superior quality.
Kyocera is one of the oldest solar panel manufacturers and is second only to Sharp amongst the Japanese companies.It also manufactures industrial ceramics, telecommunications equipment, office document imaging equipment, electronic components, semiconductor packages, cutting tools, and components for medical and dental implant systems.Kyocera Solar Corp. in Japan was founded in 1996, and Kyocera Solar, Inc. in the U.S. in 1999.The company has production bases in Japan, Mexico, Europe and China and is planning a factory in California as well.The company plans to reach 1000 MW of production by 2013.

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.

olar Panel Manufacturers are present in most parts of the world with Korea,China,Taiwan,USA,Japan and Germany dominating.Solar Panels are of mainly 2 type – crystalline and thin film.Most of the solar panels produced today are of the crystalline type and are mostly used in residential rooftops.Thin film panels are mostly used in large ground solar power plants.Thin film solar panels are of lower efficiency and are lower priced as well.However falling costs of crystalline solar panels has led to their increasing dominance.
Solarworld AG
Germany till a couple of years was the home of the biggest solar panel manufacturers in the world.This was driven mainly by the German Renewable Energy Law (EEG) which is the most successful renewable energy subsidy in the world.The German Solar Market has become the biggest in the world for the last 2-3 years and an estimated 25 GW of solar panels would have been installed in Germany.Capitalizing on a large domestic market a number of solar companies like Q-Cells,Solarworld,Solon and others became the biggest in the world.

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.

DuPont Apollo is a wholly-owned subsidiary of DuPont started a 50 MW thin-film photovoltaic module manufacturing facility at Shenzen in 2010. DuPont Apollo is focused on the China domestic market but seems like that they are not getting too much traction in the hyper competitive Chinese market and now trying its hand in the Indian market where solar manufacturing industry is not too competitive.
Indian Solar Energy Market has seen the entry of many foreign companies eager to tap this huge opportunity.This list of foreign solar companies in India keeps growing on a daily basis with both startups like Abound and large companies like First Solar,Suntech making India as an integral part of their global growth strategy.DuPont the global chemicals giant too has entered the solar energy industry in partnership with Wipro EcoEnergy.DuPont Apollo will supply Wipro with its Thin Film Amorphous Silicon Solar Panels which will be used in the grid projects.Note a number of Joint Ventures in Indian solar industry have been recently formed.

Having good solar radiation data is essential for building solar power plants anywhere.USA and European Union have a well-developed insolation map so that developers and investors in solar energy have no difficulty in getting good data while planning an investment.However Indian developers are at a distinct disadvantage as there is no good primary data to go on.Solar Radiation data makes a huge difference to the economics of a project and no bank will give a loan based on incomplete data.For the inexperienced developers this has become another problem among a host of other problems.With little understanding of the technology and other factors,many of them jumped in and are now in a deep soup.However the prospects of the Indian solar energy are great even with these initial hiccups.The flushing out of the weak hands should help in strengthening the solar energy industry in India in the best traditions of capitalism.

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.

Maharashtra which is the largest power generating state in India but deficient in renewable energy sources of generation will not use the discredited reverse auction bidding mechanism being used in the First Phase of the JNNSM Federal Solar Subsidy Policy.The reverse auction bidding was done due to the massive deluge of applications for setting up solar PV and solar thermal power plants.Based on the Rs 17.91/Kwh Feed in Tariff,developers had bid discounts with the solar project owner offering the biggest discount winning the right to build the solar power plant.This had led to irrationally low bidding for projects and it is all but certain that these solar projects will either be not be built at all or run into heavy losses.

Silicon for Solar Cells that are used to make the normal crystalline solar panels is known as Polysilicon.This is a highly purified form of the Silicon Metal that is mined.Note Polysilicon is made through chemical processes which help in purifying the raw silicon and removing the impurities.The Silicon that is used to make Silicon Cells is also used to make semiconductor wafers which is the raw material for the Electronic Industry.Solar Cells require slightly lower purity of 6N compared to the higher 9N required by the Semiconductor Industry.Once Polysilicon is produced it has to be made into flat wafers which require further industrial processes like pouring the metal in crucible to make ingots and then cutting the ingots by wiresaws to make solar wafers.The solar wafers are then converted into solar cells by processes like diffusion,etching etc.

A lot of confusion exists about solar cells efficiency about which technology results in how much efficiency and the difference between solar cells and the solar panels efficiency.Note the biggest differentiator of a solar cell besides its cost is its efficiency.Not only do different materials give different efficiencies,even different companies have conversion efficiencies which differ for the same technology.Silicon Solar Cell Efficiency also depends on the purity of the solar wafer which is used as raw material to print solar cells besides whether it is monocrystalline or multicrystalline solar cells.With most of the low lying fruit already gathered in respect to lowering cost of the silicon solar cells,most of the big Chinese solar companies are concentrating their efforts in improving the efficiency in order to cut down costs in the cutthroat solar industry where the stars of yesterday are fighting to stay alive (Energy Conversion Devices,Evergreen Solar).This rising tide of the solar industry in 2010 has not been able to revive the fortune of some companies though European companies have made enough to fight another day.Solar Cells Efficiencies also differ in the champion cells tested in labs like NREL and on commercial lines.But here is a general range of efficiency of different types of solar cells made from different technologies
Solar Cell Efficiency Improvement is the best way to reduce the costs of solar power and reach grid parity in most places in the world.Solar Cell Efficiencies have improved continuously and with a number of companies and startups investing billions of dollars in research,it will keep improving.However cost considerations are an important factor as well and the technology which balances the two will win the solar energy race
