Kaneka is a Japanese company which is present in a number of product categories like chemicals,functional and expandable plastic products, foodstuffs, life science products and synthetic fibers.However the main focus of the company is in Thin Film Solar Panels.Kaneka has been developing amorphous silicon thin film technology since 1980 and has advanced manufacturing into developing higher efficiency tandem microcrystalline silicon solar panels.The company also sells transperant see through solar panels.Note Thin Film Technology is facing existential threat from the rapid price reduction in the mainstream crystalline silicon technology which comprises about 85% of the global solar panel market.Kaneka sells its solar modules under the HYBRID brand name which refers to its hybrid tandem thin film silicon technology.Note other companies like Sanyo,Mitsubishi.Oerlikon have also developed this form of technology which gives higher efficiency solar panels as it captures a bigger part of the solar spectrum.
Solar Power in Australia has grown massively in 2010 and 2011 driven by state feed in tariffs also known as the solar bonus scheme or solar credits.This has resulted in the capacity limits being reached and most of the state solar subsidy schemes have been withdrawn (see the current state feed-in-tariff schemes below).However the Australian federal government is still offering the Renewable Energy Credit Scheme under which solar power generated is eligible to get solar credits which can be solar in the open market for cash.This will still drive the use of solar energy as the falling prices of chinese solar panels has made solar energy near electricity price parity in a number of places.Australia which gets a lot of sunshine is ideal for solar energy which promotes climate change mitigation as well besides reducing pollution.Australia has the highest average solar radiation of any continent in the world, which means solar industry has the greatest potential.
Solar Inverter Efficiency is increasing every year with increasing scale of operations,greater competition and rising R&D dollars being poured into solar inverter development.PV inverter Efficiency is vital to decrease the costs of solar power which is currently more than that of fossil fuels.While the cost of solar panels has come down drastically by almost 75% in the last 3 years,solar inverter costs have gone down by only 10% every year at most.The reason is that competition is lower in the PV inverter market because of the higher entry barriers of technology.While Western solar inverter manufacturers routinely get above 95% efficiency,the Asian low cost players have not been able to cross the technology hurdle of high efficiency.Note the Power Electronics in a solar system can make a huge difference to the power yields with even a 1% change resulting in thousands of dollars in difference in large scale solar farms.This is the reason that high efficiency solar inverters from the West command a big price premium over the less reliable lower quality PV inverters.You should be careful of any lesser known inverter brand they are offered as part of a home solar power system before installing them. While some of these inverters may have certification this does not mean they can perform as well as the good brands.Skimping of a few dollars here and there may make you penny wise and pound foolish.
Bosch started out into the Solar Energy field by making a very expensive acquisition of a Tier 2 German solar company Ersol in 2008 for Euro 1.1 billion.Bosch paid a premium of 60% for buying out Ersol which was a manufacturer of wafers,cells and modules.The company paid a very price to buy Ersol which was a jack of all trades kind of solar company without any substantial competitive advantages.Bosch had set a target of Euro 750 million from renewable energy (don’t know whether they met it ).Bosch made a bad decision because at the current stock prices it can buy almost the entire German solar panel manufacturing sector for Euro 1.1 billion.Its doubtful that Ersol would have survived the current solar panel downturn and was extremely lucky to get bought by Bosch for that price.The company also bought two other small German solar companies at expensive valuations Aleo Solar and Johana Solar (a thin film solar panel producer).It could have similarly bought these companies or even better companies at much cheaper prices.
Solar Panels are sold by hundreds of companies around the world ranging from small to very large and comes in various shapes and sizes as well.Besides this solar panels are also made of very different materials for example silicon solar panels and thin film solar panels.So comparing solar panels and choosing a solar panel is a very difficult process if you want the best solar panel according to your need.The most efficiency solar panels are needed in cases where the land area or rooftop area is at a premium.Note a typical 200-250 watt solar panel requires an area of 60×38 inches which means an area of around 2000 square inches.1 megawatt of solar panels would require an area of between 5-10 acres of land depending on the efficiency of the solar panels.However this can be reduced by using solar trackers which can increase the output of solar panels though they to increase the area requirement slightly.Also the area also depends on the location of the place since a place recieving high sunlight for example California would require lesser area for generating the same amount of electricity compared to London (upto 30% fewer solar panels).Note solar panels with higher efficiency have a higher price tag associated with them since they require higher cost to manufacture.The most efficiency solar panels which are used in spacecraft and have a efficiency of around 35-40% may cost upto 100 times more than the normal silicon solar panel.
Solar Panel Manufacturers in USA are facing a torrid time from the falling prices of Chinese solar panels.This has caused the bankruptcies of some big solar panel companies in recent times like Solyndra,Spectrawatt and Evergreen Solar.Only those solar panel companies with the lowest cost and good quality will manage to survive the price war in solar panels that is currently on.Most companies are running losses as the prices of solar panels have decreased by 40% in 6 months.This would cause any industry to see massive bankruptcies and this is the case with the solar panel industry as well.Note Solar Industry is a new one with rapid technology and cost changes which makes startups with bad business models go bust.This is a natural effect of capitalism and nothing to be afraid of .However you have to be careful of which solar panel manufacturer to buy from as your 25 year solar panel warranty will become useless if the solar panel manufacturer from which you brought the solar panel goes out of business.On the Bright Side the sharply declining costs of solar has made it the biggest advantage of using solar power.
