Solar is experiencing growing worries Who "labor pains" pay - heat pumps, solar energy, air conditioning - heat pump industry

Solar Energy The decrease in solar panels price solar energy sufficient to manufacturers of Western "very hurt", but not low to make solar power in the electricity market is very competitive.

Solar popular because it is a clean and abundant resources. Its problem is the high cost of electricity. According to the International

Energy Department has estimated the cost of solar PV 200-600 USD / MWh, the cost of the main factors affecting the efficiency and the future installation of a discount rate of output. According to the International

Energy Department estimates the cost of U.S. land-based wind power is about 50-70 USD / MWh. Not to impose greenhouse gas emissions in the emissions tax case, the cost of fossil fuel power generation is even lower.

The cost of solar power has been declining, in sunny areas, the next few years, the use of solar power may be lower than the cost of purchasing electricity from the power-line costs. This is the future expectations, but the front view, without government subsidies, solar power generation market is still competitive.

View of the different countries of the subsidies, some countries subsidies are generous, the local market can grow rapidly. According to Bloomberg research institute New Energy Finance estimates that by 2010 global demand for solar PV will reach 10.5 GW. Global demand in 2006 was only 1.7 megawatts. Germany, the electricity price subsidy policy is that the four years the engine of prosperity, the solar industry, Germany's policy to ensure each piece in the German solar panels are installed profitable. At present, the global solar cell supply and demand in balance.

However, solar cell prices started to decline last year. Mainly due to relatively low prices of Chinese companies to enter the solar market. 2007, California launched an incentive to install solar panels on the roof "solar installation project," At that time, China's solar energy components from only 2% of the share, however, the fourth quarter of 2009, the group from China the proportion of cases have accounted for 46%.

Lower component prices, electricity price subsidy policy looks more attractive. Prices, installed capacity of solar cells in Germany rose. Germany 2009 MW cumulative power generation capacity of 9677, this number is almost 21,500 MW of total generating capacity of the world half. Therefore, the German electricity price subsidies reduced, and will continue to decrease this summer. According to Germany's largest solar cell maker Q-Cells, said the company's market value in 2009 reduced by half. Solar cell manufacturer profit margins greater degree of decline. Companies with good brand can sustain high prices, but after all, solar is still commodity, capital is king in the era of low-cost solar energy manufacturing industry in the areas necessary to conduct large-scale production, which is a lot of companies outsource production to China reasons. According to the World's largest solar energy equipment manufacturer, Applied Materials, Inc. technical staff Mark? Pinto say, now half of the world's production capacity in China. He added: "The Chinese solar product manufacturing capabilities far beyond the projected Applied Materials, the world's 2 / 3 of the new capacity from China."

Solar panel prices make people more interested in building solar power stations. In 2007, Spain launched huge electricity price subsidies, led to a wave of building solar power stations. In the Spanish government before the introduction of caps on the total installation of 2 GW installed.

First Solar is currently the largest supplier of solar cells. It is mainly the development of thin film solar cells, this battery required silicon content than the less crystalline silicon solar cells, and even do not need. However, the conversion rate is also its greatest weakness. Thin film solar cell is more suitable for the desert or the sunny suburbs, does not apply to the roof, the roof, after all, space is limited. First Solar's cadmium telluride thin film to as raw material, made of thin film solar cells more expensive than the cost of silicon-based thin film solar cells is much lower. However, many people do not optimistic about thin film solar cells. They are based, once the general decline in the cost of solar cells, thin film is no more on the edge. Moreover, the film production process that does not show the traditional production process of destructive, on the contrary, large companies are often willing to invest in films, because they want to diversify their investments.

Solar power are not only costly disadvantage, as well as use of low rates. As the night, cloudy days, solar panels, dirty face and other reasons, the utilization of a solar power station can only reach its maximum power output of 1 / 5.

Despite the global economic recession is at, though full of solar energy industry is experiencing troubled adolescence, however, the global solar energy industry installed capacity and investment, both showing a growth trend.

The Editor Solar energy has a cute little guy, and placed in it infinite hope. Perhaps one day it will grow into a robust citizen, or as a great growth. However, at present neither a spoiled child, did not grow into a Duchuang adult world, it is in the small adolescent love. The embarrassment of solar energy to the hope that it "grown up" and hope to profit from government enterprise to challenge. How to support the national policy in the end, companies should continue to develop thin film crystalline silicon or turn? These are the growing solar energy had to answer. No one doubts that the future of solar energy industry continued to develop, but the question is, who pays the bill for these growing pains.
