DC Solar Power System Solar battery
The world has nearly 200 companies producing solar cells, but the production plant mainly in the hands of Japanese companies.
South Korea's Samsung, LG have expressed the desire to actively participate in the Chinese cross-strait is also very enthusiastic. It is reported that China's Taiwan 2008 crystalline silicon solar cell production capacity of 2.2GW, the future will be 1Gw annual production capacity to expand, then began to produce thin-film solar cells, will be greatly enhanced, Taiwan look forward to the European "solar cell power" line. 2010, countries and regions have more than 1GW production plan of solar cell manufacturers are Japan Sharp, Germany Q-Cells, Scho ~ Solar, Norway RWESolar, China SuntechPower and other five companies, the remaining seven more than 500MW production capacity of the company.
The world's solar cell market triumph, a good, but a rare financial crisis brought about by the economic crisis, the same pressure on the head of the solar cell market, a dark cloud, the main business, such as the German Q-Cells performance should be reduced, the world's solar power market Will be due to weak demand, oil prices and competitiveness of the anti-promotion and other unfavorable factors and fell. But at the same time, people also see the United States. Obama will come to GreenNewDeal policy, including its green energy plan may have 150 billion US dollars of subsidy funds, Japan will also implement the subsidy system to continue to popularize the application of solar cells.
At present, about 90% of China's solar cell production before the supply of overseas markets, mainly for European countries and the United States, but with the European debt crisis continued fermentation, the US Department of Commerce in March 2012 made a countervailing counter on China's solar cell products The investigation of the preliminary ruling, found that China involved enterprises there 2.9% -4.73% range of subsidies, and traced 90 days tax. These factors directly affect the performance of these enterprises, so the relevant enterprises in a timely manner to make business strategy adjustment, to switch to China's domestic market. July 2011, the Chinese government announced the solar photovoltaic power generation price, affected by a number of companies began to plan in the country to build large-scale solar power stations, solar cell companies in China will focus on opening up the local market. China has more than 800 solar cell business, is expected in the future competition in the local market will be very intense.
Solar use editing
The use of solar energy is divided into several aspects: the family with a small solar power station, large-scale grid-connected power station, building integrated photovoltaic glass curtain wall, Yuxiang solar street lights, wind and solar street lights, wind and solar power supply system, the main application for the building And the wind and light complementary system.
