Experts predict that over the next 20 to 30 years, the world's energy structure is bound to a fundamental change in the 50s of this century, new energy and renewable energy will account for the entire energy constitute 50%. Solar as a great potential for development of new and renewable sources of energy, has long attracted wide attention from countries around the world, China has also done a lot of research, it is regrettable that many years have passed, solar power seems to have been in people Is a distant concept and symbol, you can feel better, but it may not close, then the threshold of solar power, how high can not end the industrialization of the disease and there, this new energy power generation of what one of the main characters When gorgeous debut, all people want to untie the Miju ... ...

       How many capacity of solar energy

According to the authority of the world's energy sector, the world's proven reserves of fossil fuels, the main production and the people of the world can not be optimistic. Remaining recoverable oil is only 41 years, their share of world total energy consumption of 40.5 percent; remaining recoverable natural gas 61.9 years, their share of world total energy consumption of 24.10 percent; remaining recoverable coal in 230 years, In its World Energy accounted for 25.2 percent of the total consumption; remaining recoverable uranium 73 years, their share of world total energy consumption of 7.6 percent; otherwise water in the world in its total energy consumption of 2.6 percent. 

Traditional fuel energy is being reduced day by day, the energy issue has become can not be ignored global issues. Search for new energy sources has become urgent. It soon had focused its attention on the side of renewable energy, wind energy, solar, geothermal, biomass power generation ... ... The new energy has become a substitute for the traditional one-time goal of the new energy. And a wealth of daily solar radiation is inexhaustible, pollution-free, low-cost, free use of human energy and become the first people into the field of vision the best choice. Solar energy per second to reach the ground up to 800,000 kilowatts, if the earth's surface to 0.1 percent of solar energy into electrical energy, changes in the rate of 5% per annum capacity of up to 5.6 × 1012 million kilowatt hours and the equivalent of the world's energy consumption 40 times or so.

China's solar energy is one of the resource-rich countries. China's desert area has 1,080,000 square kilometers, mainly in the light of resource-rich Northwest. 1 square km area to install 100 megawatts of photovoltaic arrays, the annual power generation 150,000,000 degrees; if the development and utilization of 1% of the desert, they can be issued equivalent to the year 2003 China's power consumption. At present, in China's north, and many other coastal areas, the annual amount of sunshine are more than 2,000 hours, Hainan has reached more than 2400 hours, is worthy of the name of the great power of solar energy resources.

Such a huge energy reserves, the development of our situation and how it?

China's solar energy industry reduced to a processing plant outside the environmental protection industry

Solar cells can convert solar energy into direct current energy, solar photovoltaic industry is the production chain, the most critical. At present, the world's most widely used solar cells are crystalline silicon solar cells, and the production of crystalline silicon solar cell raw materials - high-purity polysilicon in China but there is a tremendous shortage, most of the need to rely on imports. According to the Chinese Academy of Engineering experts to investigate, in 2005 China's demand for polysilicon 3800 tons, of which photovoltaic industry needs 2691 tons, and in 2004 China's output of polycrystalline silicon is only 60 tons, even if the supply of all the photovoltaic industry, Only 2.6 percent of the market demand, the rest have to rely on imports. To form a well-known Chinese PV industry, "two out" phenomenon: 90 percent dependent on imports of raw materials, 90 percent of exports. On the surface, because the high cost of solar cells, temporarily unfit for domestic widely used. The direct cause of this phenomenon can not keep up because the technology and raw materials under control.

Solar photovoltaic cell manufacturing chain: quartz sand - polysilicon - cut into silicon (or a single crystal silicon) - battery components and battery (not a single piece battery power), and then components Combination in the final installation projects for power generation. The monopoly of transnational corporations, it is polysilicon. The world's seven major companies control almost all the high-purity polysilicon sales and manufacturing, they do not cooperate or joint ventures, technology completely closed.

In fact, the upper reaches of the polysilicon raw materials quartz sand in our country there is no shortage. Polysilicon many overseas companies have a direct procurement from China. However, Chinese enterprises for the silicon purification technology, has been the lack of progress.

In the 1990s, there are more than 40 small companies in the study of polycrystalline silicon technology, but is not a company can undertake large-scale production of polysilicon. Technology can not break through the bottleneck, many others will be completed, even if there are no raw materials, technology, we can only become cheaper abroad, the environmental protection industry processing plants. Thus I have been led to the solar industry move forward. Solar power generation and the cost of traditional coal power generation costs than the current price of solar power generation Internet is about 3.5 yuan / kwh, is a common electricity generating units of the Internet about 10 times, so be very costly and is clearly not popular Possible, so we have no alternative but to enjoy the warm sunshine, looked at a lot of energy in the loss of close to, and do nothing!

A number of walking legs, China to seek a way out of the new solar power generation In order for solar power generation at an early date close to the people, domestic research institutions have done a lot of work. Recently, the Japan Science and Technology Agency take the lead in China's Wuhan University of Technology, Tsinghua University, Shanghai Institute of Silicate and Japan Aerospace Exploration Agency, Japan Aerospace Technology Foundation, Northeastern University and Japan's Toshiba to participate in the solar thermal power complex The system will continue to develop and will start in April this year in China's desert area in Inner Mongolia for one year model of durability testing, and gradually turn into one operation. Solar thermal power generation system is complex and visible use of the ordinary solar system useless or harmful infra-red new power generation system. The system through the special lens to gather the sunlight for the separation of infrared and visible light, visible light through reflection for the small solar cells, through a special infrared camera modules for electric power generation. At the same time, due to the use of both visible light and infrared energy, power generation efficiency of existing solar-powered 2-fold. In addition the system can also use waste heat to provide hot water, solar energy utilization rate reached 65%. In the absence of removable parts, is a maintenance-free power generation methods, applicable to the desert area. The system in the western region to support the country as a "bright project" part of western China will be 23,000,000 lack of power to provide electricity to families.

There are recent news, the China Science and Technology University developed a new type of Tingri mirror, can effectively track the sun's rotation, making use of solar power generation than coal-fired electricity generation is expected to lower the cost of in-house. Tingri this mirror mirror on the sun's position for any incident that can be effectively eliminated by the mirror design defects caused by the aberrations that can effectively track the sun's rotation, the system can be controlled by the normally-Tingri Just down the required two-dimensional control for control of one-dimensional. As the solar condenser of a significant reduction in the cost of human will be in-house costs more than coal-generated electricity low.

This shows that through the efforts of solar power generation in China is not in power when the tension is a new concept of energy speculation over the years not just listen to the talk leading role debut of the situation will become a thing of the past, solar energy as the most potential and resources of the richest The new renewable energy, power generation used in a large number of the day, and so we will not call for a long time!

Foreign solar energy industry development Germany: Bavarian State will build a large-scale solar power generation market  Solar power generation technology in the world in the forefront of Germany, in the Franconia region of Bavaria's Stein Arne into large-scale solar power generation market, and its power generating 12.4 megawatts, at the same time meeting the family's 3500 electricity needs.

The solar field covers an area of 77 hectares, will have 1,500 sets of solar power installations. It consists of two private joint planning, after the completion of power generation is currently the world's largest 5-megawatt wind power station more than twice as much. The two companies plan to complete the purchase through private methods to raise funds to build the necessary market 75,000,000 euros. The purchase of personal sets of solar power installations need to invest 14,400 euros. According to the survey, the solar energy market to raise funds to build new channels in Germany have broad prospects for development. 

 Production of renewable energy resources of modern science and technology has been popular in Germany. German Environment Ministry commissioned the Forsa market research agency in early May 2005 to investigate the results showed that nearly 62 percent of Germans think we should increase the renewable energy input. The majority of respondents support the use of wind power, and endorsed the efforts in the next 20-25 years to achieve. The use of offshore wind power stations to meet the country's electricity demand by 15%. 

In the next 20 years to 30 years, solar energy will be another great strides in the development of energy sources. The survey also showed that 85% of the German people to solar energy as a substitute for the traditional ideal.

Japan: Government to sell its power generation but also 

In 1973 the first oil crisis broke out in Japan has had a major impact on the oil crisis put an end to Japan's era of rapid economic growth. Since then, the Japanese government to promote energy conservation and strengthen the development of new energy, energy relaxation of restrictions on developing new energy sources, the use of solar, wind, fuel cells, hydrogen energy, such as superconductors can be. Japan is seeking strong angles and a full range of energy security, these efforts to protect the environment and to build new levels of sustainable development. In the alternative energy and energy-saving technology R & D, Japan willing to invest in an attempt to ensure that the future of energy science and technology high ground, to launch "a new scheme sun", with an annual allocation of more than 570 billion yen in research renewable energy technologies, energy transportation and storage technology.

In Japan, solar power is very popular. Within the family, the popularity of solar power generation cost is very high and difficult. The purchase of solar devices can cost more than electricity cost is the key, which is impossible in the past. At that time, the solar power plant is difficult to sell because the sale of a small number can not be a large-scale mass production.

Now, the family purchased the device, half the cost of government subsidies to, so now sold more and more, the price also declined. It is understood that 10 years ago, Japan 3 kilowatts of power generation equipment, the price is about 6,000,000 yen, which is probably enough to pay for decades of electricity, and the current market price to reduce by half. Converted into yuan, 400,000 yuan down from about 20 million.

In Japan the use of solar power generation device has a unique advantage: no electricity during the day, but power companies to sell electricity or government, which has an active acquisition, so that income can be used to offset part of the electricity. According to the statistics we can see an interesting situation - in the popularity of solar power generation family of devices, power-saving work done instead of better.

After years of hard, and Japan as the world's highest energy efficiency one of the countries (the United States for 2.75 times). Japan, the world's leading solar energy technology, in 2002 Japan's solar power generation accounts for 46% of the global total.

South Korea: in 2006 the building will be the world's largest solar power plant South Korea, South Jeolla Province government has said they will be held in April the company together with the United States, the world's largest solar power plant construction, power generation 17 megawatts per hour.

The power generation plant of its kind in Germany than 5 MW power plant per hour, is currently the world's largest solar power plant. Earlier, South Jeolla Province government and the U.S. wholly-owned by the Group of Kore a project agreement, the project 150,000,000 U.S. dollars of foreign capital injected.

The agreement is based on the region's government and the United States in 2004 Memorandum of Understanding (MOU) on the Korean Peninsula in the city of Mokpo building solar power plants. MOU clear Kore Group to provide financial resources and supervision.

Israel: legislation to promote the development of solar energy It is well known that Israel is an ample sunshine, and solar energy resources in the country with better conditions, the use of solar energy technology research and development, not only by government departments, research institutions and enterprises attached great importance to and at the same time, with the United States, Europe and Australia Countries and regions have wide-ranging co-operation between Israel so that in this area has been the world's leading ranks.

An area of 1000 acres, generating power for 500,000 kilowatts of the world's largest solar power plant in southern Israel in the Negev desert in the building. The solar power plant generating capacity will reach a 100,000 kilowatt, the project completed in 2012, generating capacity will reach 500,000 kilowatts and the power output to the national electric power production accounts for about 5%. For a long time, Israel has always attached great importance to solar energy technology research and development, domestic well-known research institutions in the development of solar energy technology has made many important achievements in the development of Israel and the use of solar energy technologies to maintain the world's leading level. However, due to the high cost of solar power, Israel has greatly restricted the development and utilization of solar energy. The power station is Israel's first solar power station.

Israel's lack of conventional energy is the only legal requirement to be civil to install solar water heaters, therefore, Israel's penetration of solar water heaters up to 90%, per capita use of solar water heater area in the world.
