about the use and development of energy, is a global discussion hot topic in the recent 20 years. First, regardless of his lack of energy of the whole world alone, China have experts have made investigations, thus draw the conclusion that, in accordance with the existing energy demand, China's coal is less than 100, ok the oil less than 20 years, wind, water resources, even if all development can all provide 20% of its energy, and our country's energy demand is still at the rate of doubling every 10 years rapid growth. So many questions, not future generations, and so on, our own?

the people confused problems, solar energy as the 21st century it is possible that the time is the most clean and renewable resources into people's horizons. According to relevant data reflect, and the sun is the source of most forms of energy on earth, if able to one over one thousand of the solar radiation energy for power generation in China, is enough to solve the national electricity demand. When the human face of traditional energy sources dried up, only the abundant sunshine, is the problem of energy a permanent solution. Now, the solar power generation capacity equivalent to only a small power plant, the global solar power generation capacity and no one of the three gorges, photovoltaic (pv) in the future market space is huge, Including solar street light, solar garden light) 。 Since the second half of 08, last 1 years of the global financial crisis, a winter brings to the photovoltaic market. Component prices fall more than half of the year. Brought greater opportunities but at the same time, the pv KWH cost from $36 m solar street lights above dropped to close to 1 yuan. Governments around the world photovoltaic huge potential economic value, gradually begin to realize the necessity of photovoltaic application and promotion. Pull the power of the pv market growth extended to many countries. The United States, China, Japan, Italy and other countries of the government's push, will drive the photovoltaic industry prosperity once again.

the long term, thermal power, hydropower, wind power, nuclear power are faced with raw material prices, the rising cost of resources, comprehensive cost are facing a sharp rise. Coal, for example, according to greenpeace, considering the external costs, such as resource depletion, pollution, the comprehensive cost of 0. 6 yuan, and the growth rate is about 5% per year. In all the major forms of energy, photovoltaic, only has a huge space for cost reduction. According to this trend, photovoltaic power generation cost would no longer be a disadvantage in five years. Especially in the global energy prices higher region ( Including Europe, North America, etc. ) , the cost of photovoltaic power generation will start below the electricity price for residents, the so-called parity throughout the Internet &; 。 That is to say the government is no longer needed subsidies, pv's own economy can prompt people to install. By then, cheap, clean solar electricity will be sought after by money, while facing the real blowout. Current global photovoltaic industry chain in China, more than 60% of the annual sales revenue contribute one hundred billion yuan scale. Despite the rapid development of experienced in the past five years, however, the industry has just walked out of the bud, standing at a new starting point, to prepare for the foreseeable future, usher in a no one can predict the height of the.
