Japan's Solar Energy Manufacturing Industry is quite large and second only to China which may surprise a lot of readers. Sharp was the largest solar company by revenues and the other six zaibatsus have been present in the solar power manufacturing for a long time.Mitsubishi the Japanese conglomerate with diversified global interests has a big presence in solar and wind energy as well.It has a low profile solar module and system business.The company is known for its high quality panels and has a decent presence in USA and Japan.However like Kyocera it has not been aggressive enough leading to loss in marketshare.

JSW Energy has set up JSW Green Energy a 100% subsidiary to enter the renewable energy in India.Not while Wind Power in India is already a huge industry with more than $3 billion in annual investment,Solar Power in India is set to eclipse this soon.JSW Green Energy is looking to set up solar power plants and solar rooftops in the country.For this it has ordered 500 KW of CIGs solar panels from embattled American Thin Film company Energy Conversion Devices.Note ENER is already under huge pressure as it fails to compete with low cost Chinese players.ENER which markets its BIPV Solar Panels under the United Solar brand sells mostly in France and Italy which have higher subsidies for BIPV Panels.Like other American companies ECD has significantly ramped down and moved Green Jobs to Mexico in order to suriveNote CIGs Panels are of lower efficiency than the normal mainstream crystalline solar panels.ENER Solar Panels are mostly used in BIPV and BAPV applications since they are not as cost effective and efficient as normal solar panels.Thin Film in India is rapidly increasing penetration with the Thin Film Leader First Solar targeting 100 MW of Solar Panels in 2010 itself which would make it the biggest solar panel supplier in India.

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

It is surprising to see the US Media jumping about saying the General Electric will build the biggest solar factory in the US when it is completely factually wrong.There are other companies that add 400 MW in a single quarter these days (eg.LDK). By the time GE builds its 400 MW Cadmium Tellurium Solar Panel facility,there will be around 20 players in the world with more than 1000 MW capacity.GE has been claiming high efficiencies for its Thin Film Solar Panels but the claims that it will be able to dethrone First Solar as the Leader seems far fetched currently.Note First Solar will have almost 7 times more capacity worldwide by the time GE builds its first solar panel facility.GE has been long been developing the Cadmium Tellurium Technology buying up Prime Solar.

Solar Industry is one of the fastest growing industries on the planet and the number of companies in the industry have increased dramatically attracted by the strong growth prospects and low entry barriers.The easy availability of solar producing equipment and low capital requirements for small companies have led to a mushrooming of the number of players in the industry.Its possible to set up a small 30 MW module production factory for as low an investment as $10 million or lower.Though the value add of a pure play solar panel production factory is low and the competetive position quite questionable nonetheless there are hundreds if not thousands of such small module producers in the world right now.Other parts of the crystalline silicon supply chain have also got a number of players though the technology and captial requirements are much higher.Listing out all the solar companies in the world is a difficult task and somewhat useless as well as many of these small scale solar companies will not exist in a few years as competition keeps intensifying.Consolidation in the solar industry will ensue sometime or the other and lead to a much smaller and sustainable industry.

Solar Roofs are a niche area but is growing in popularity with the entry of more and more companies selling products tailormade for this area.What are Solar Roofs exactly - does it mean a Roof with Solar Panels installed on it or something else.Solar Roofs are not roofs where solar electricity is generated by putting in solar mounting/racking systems and mainstream solar panels,rather they are roofs where specialized solar products called solar shingles are installed.Solar Roofs can also mean a roof where Building Integrated Photovoltaic products are installed.Some companies make BIPV products like flexible solar panels or organic/dye solar cell panels ( these are niche companies).

Solar Energy in Japan has a long future dating back to 1994 when the government introduced capital subsidies to boost solar energy installations on rooftops.Till 2004,Japan was the largest solar market in the world after which it was overtaken by Germany.After 2004,the growth in the solar industry tapered off as the government reduced the subsidies for solar panels to almost zero.The huge domestic market gave rise to Japanese companies like Sharp,Mitsubishi,Kyocera,Panasonic-Sanyo become top solar panel producers in the world.However the low cost Chinese solar module producers have pushed back most of the Japanese companies.Since the last year,the Japanese government has again started giving generous solar subsidies and feed in tariff to boost the renewable energy production in the country which remains far off targets.This has led Japan to become the top non-European market after USA and the growth seems set to continue in the future as well.Japan has relatively low installations costs and is much nearer to grid parity.Also lack of wind energy makes solar energy more attractive as a renewable energy choice.While large scale solar installations in Japan are almsot absent,there remain large numbers of rooftop solar installations.

Chinese Solar Companies have increased their global marketshare of the Solar Panel to around 60% from virtually 0% in 2006.The Solar Panel Dominance of the Chinese has been growing since last year as Europeans and Japanese have found no answer to their cheap solar panels.Q-Cells,Solarworld and other European companies have been reduced to bit players in the Solar Market as the low cost Asians have ramped up their capacity and shipments in 2009 and 2010.The only reason that they continue to survive is the more than 100% growth in the Solar Demand in 2010.With oversupply expected in 2011,Europeans will be virtually wiped out from the world solar panel market due to their high cost uncompetitive business models.European solar factories are closing as the remaining companeis shift their production to low cost Malaysia and Singapore.

First Solar,the US based Cadmium Tellurium (Cd-Te) is the lowest cost panel producer in the world today if you don't include any penalty for low efficiency.Even if you penalize the Cd-Te Technology for its lower efficiency vis-a-vis the higher efficiency crystalline technology,First Solar is clearly the leader with a core cost of 74c/watt.The company has a roadmap of reducing the cost to 52c/watt by 2014 and given its track record it seems quite achievable.In Cd-Te,some new competitors have claimed even lower costs than First Solar but they have yet to prove it in large scale production.General Electric,Abound Solar are some of the other Cd-Te players which are planning commercial production in a year or two.But with around 2 GW of capacity,they will have a lot of catching up to do.

Solar PV Technology have made a huge advance in the last 2-3 years leading to a demand explosion with more than 100% growth forecast this year.Crystalline PV Technology as well as Thin Film Technology like CIGs and CdTe have reduced their costs drastically.While Solar PV still requires generous government subsidies for their growth,grid parity has come very close.Solar PV Technology has become economically competitive in parts of Italy where a unique combination of high electricity rates and sunshine have made Solar PV Technology very attractive.Costs are being reduced at more than 10% per year which would make Solar PV competitive in 2-3 years in most parts of the world.However mainstream and reputed forecasters and companies like Boston Consulting Group remain blind and ignorant to this.BCG in a recent report has said that biofuels and Concentrated Solar Thermal (CSP) Technology will become competitive.I have issues with both of these technologies.

Solar Frontier is a subsidiary of Showa Shell Sekiyu and is listed on the Japanese Stock Exchange.The Company has big plans for the Solar Energy Market planning to increase its capacity by more than 10 times in 2011 to around 1 Gw in total.All its 3 plants are located in Miyazaki in Japan and uses previous plasma plant of Hitachi.Solar Frontier claims 11.5% efficiency for its CIS modules which are expected to go upto 14% by 2014.The Company is spending around $1 Billion in Capex for building the 1 GW capacity implying roughly $1 capex/watt which is not exactly cheap though not very expensive either.Note Thin Film Competition is hotting up with Saint Gobain-Hyundai,TSMC,Miasole,Oerlikon Solar,Sharp,Nanosolar all making plans for huge capacity expansion in the next couple of years.Solar Frontier has signed some small deals for supplying 1-3 MW in Thailand,Japan and Australia Recently.However the cost structure of the company is not known till now just like Sharp.While Solar Frontier looks good on the capacity and partnerships front,it has still to prove itself on costs to really push the Chinese Solar Companies which are dominating the Solar Scene right now with their low cost polysilicon panel production.Note 60% of the Solar Panel Production in Q210 was estimated to be done by Chinese based manufacturers.

GE is now looking to dethrone the No.1 Solar Energy Producer First Solar using its all round strengths.GE had invested in a Cadmium Tellurium Startup Prime Solar which is ramping up production.Note Cd-Te is the same technology which is used by First Solar.GE has said that it has managed to attain 15% efficiency on commercial glass.Don't know how much of it is true since First Solar only manages around 12% efficiency despite around 10 years of dedicated R&D.However if GE can even manage to get near to that level then it would surely give First Solar a run for its money.GE has also tied up with Japanese Solar Frontier to market its CIGs based modules.Note Solar Frontier or Showa Shell is building a massive 900 MW plant in Japan.This would make Frontier Solar one of the biggest Solar Players in the world.GE is offering an integrated solution comprising of modules,inverters,services and other BOS equipment to get a leg up on competition.

Saint Gobain like Semiconductor Giant TSMC is betting on Copper Indium Gallium Selenium (CIGs) Technology rather than the mainstream crystalline silicon technology.CIGs is getting the most significant investments these days compared to other thin film technology.Yesterday Ascent Solar (ASTI) got an IEC certification for its flexible modules which would enable it to target the mainstream rooftop market from niche applications earlier.Miasole has improved the efficiency and costs of it CIGs greatly while Nanosolar can't be counted out because of its strong backers.Solyndra however remains mostly in the shadows despite around $1 billion in private investment.Stion is another strong contender partnering with TSMC and also thinking of opening a plant in Taiwan on its own as well.Saint Gobain is already a big player in the solar market as it suppliers glass to a lot of solar companies for their modules.Getting into panel manufacturing will further allow it to get a foothold of this new potentially giant industry.Du Pont,Dow Chemicals,Corning all have considerable presence in the solar equipment market as well.

TSMC Cost Targets Would be Incredulous coming from any other Company
TSMC has said that it would look to become amongst the top 5 suppliers in the world in the next 5 years and looks at a Cost per Watt of only 19c/watt in the next 3 years which would be further reduced to 14c/watt.This is much lower than the current costs for the Solar Leader First Solar which is at around 75c/watt.This target if achieved would make solar energy the cheapest form of energy and would definitely make TSMC No.1.Note First Solar is planning a cost target of 52c/watt in the next few years.TSMC is planning to start production in Q211 with 200 MW of production planned for 2012.

Applied Materials which was the 800 lb Gorilla in the a-Si Thin Film Equipment raking in Billions of Dollars in Orders from established Solar Leaders like Q-Cells and Suntech also found itself in trouble.With its SunFab Division leading Millions of Dollars and fast losing its economic viability,AMAT was forced to conduct Euthanisia.Its customers like SunFilm,Moser Baer,Suntech also have pretty much shut down their factories writing off large investments.However Oerlikon is not giving up like AMAT

Honda's modules have an efficiency of 11.6% which seems lower than those claimed by the TSMC-Stion,Miasole and Q-Cells.These companies are claiming 13% efficiency though none of these companies have large scale commercial production as of now.Q-Cells and Miasole are at the head of the CIGs pack with companies like Nanosolar,Solyndra,Solar Frontier and TSMC-Stion closely following.CIGs technology is said to be the best thin film technology better than the Cd-Te technology used by First Solar and a-Si technology used by Sharp and the now bankrupt Applied Materials thin film division.

SMC seems to have made a strategic call to focus on the thin film Cadmium Indium Gallium Selenide (CIGs) Technology instead of the mainstream crystalline silicon (c-Si) technology.Note CIGs technology is the most promising thin film technology with yields much higher than the other technologies like Cadmium Tellurium (CdTe) used by First Solar and amorphous Silicon (a-Si) which was used by AMAT's Subfab division.
