Modern technology solar thermal polymerization of the sun and use its energy to produce hot water, steam and electricity. In addition to the application of appropriate technology to collect solar energy, the building can also use the sun's light and heat, is added in the design of appropriate equipment, such as the giant south-facing windows or can absorb and slowly release the sun heat the building materials . Major domestic manufacturers of solar cells is experiencing a rare "rainy days."
Since more than 95% of export production, and rely too heavily on the European market, the domestic solar companies in recent months of continuous interference by a number of negative factors: the debt crisis in Europe, the euro plunged, the European cut solar subsidies. This series of negative factors that solar cell manufacturers both domestic worries, as well as into the future. However, the resilience of domestic companies are trying to control operating costs and demand ends of the risk. Domestic solar cell manufacturing sector has two distinct characteristics.
First, the "national speed" rapid development of global market share of 1% from 2003 to 2009 soared 30%, emerged Suntech, Yingli, Trina Solar and other battery manufacturers.
Second, over-reliance on the European market. In 2009, domestic production capacity of solar cells for about 240 million kilowatts, but the domestic solar power installed capacity of only 12 million kilowatts, 95% of export capacity, which is the most important market in Europe. Over the past few years, Europe has been the focus of the world's solar photovoltaic power generation.
In 2009, Germany, Spain, Italy and the Czech Republic's new capacity of more than 4.2 million kilowatts, accounting for 60% of the world. From the beginning, Greece, Spain and other euro-zone countries outbreak of the debt crisis, the rapid deterioration of the euro, the euro fell against the dollar for more than 12% of the domestic solar cell manufacturers suffered serious losses.
