Photovoltaic cell production in the world

First post by: www.itbattery.com

As one of the new solar energy Sony laptop battery, in addition to extensive use of light in the form of heat that is common in the form of the use of solar water heaters, etc., can also generate electricity. One of the more common is the photovoltaic power generation, that is, solar radiation will be converted to electrical energy, is more mature power generation technology, widely used.



National Association of Industry and New Energy Chamber of Commerce executive vice president, group-wei, chairman of the board, said Liu Hanyuan, with renewable energy is hydroelectric power, wind power, Toshiba Laptop Battery and Fujitsu Laptop Battery compared with the four major advantage of solar power generation. The first few links into the use of direct. At present, crystalline silicon solar cell conversion efficiency in the practical level of 15-20 percent, to be used in one-time conversion of energy efficient new energy. The second is less consumption of resources. Solar power generation area of land occupied by wind power is only 1 / 8-1 / 10, and biomass power generation of 1 / 100, to build large-scale hydropower dams to the land occupied by much smaller. Third, the volume contains abundant solar energy resources. Judging from the current development of China can contain the amount of resources, approximately 378,000,000 kilowatt hydropower, wind power, about 253,000,000 kilowatt, while solar energy is 2,103,900,000,000 kilowatt. The fourth is in the process of solar power is no waste residue, waste, waste water, waste gas generated.  Judging from the current generation of various forms of carbon emissions, if we count the upstream area, solar photovoltaic power generation close to zero emissions, coal and oil for power generation,  natural gas and even wind power, he must meet certain emissions.



For this reason, solar photovoltaic industry has been regarded as the most environmentally clean and sustainable energy forms, in recent years has been the rapid development of the world. Over the past 10 years, the global PV industry average annual growth rate of 41.3 percent in the past 5 years was 49.5% in 2007 than the 56.2 percent growth in 2006. In the face of resource depletion, environmental degradation caused by the energy crisis, solar energy, with its broad distribution of the resources of clean, renewable energy technology development, as well as the full, has been favored by many countries.



Sync with the global, China is rapidly emerging as a solar PV cells produce power. In 2000, Chinese production of photovoltaic cells was only 3 megawatts by the end of 2007 reached 1088 megawatts, ranking first in the world. Since December 2005 Suntech Power Co., Ltd. in New York Stock Exchange, less than two years, there have been more than 10 Chinese enterprises in the PV market at home and abroad.



The local market to be developed



The Chinese government supports the development and utilization of solar photovoltaic power generation. 2002 to 2004, the National Organization of the rural power transmission project, the central and local governments will total 4.7 billion of funds in Inner Mongolia, Qinghai, Xinjiang, Sichuan, Tibet and Shaanxi provinces and regions in 12 townships in the city of 1065, Sony PCGA-BP2T battery the building of a Photovoltaic power granted to renewable energy-based power plant.



Before and after the Olympic Games in Beijing this year, solar photovoltaic skill demonstrated time and again. May, Suntech's successful Olympic torch climb Everest services, and later for the main Olympic stadium provides a bird's nest of green emergency power system. In the landscape of the Olympic Park Avenue, Sony PCGA-BP2V battery stands the Art produced by the Group of 29 solar power generation components of the column of information, played a shade, power generation, multi-function watch, and so on.



However, with China's huge production capacity of photovoltaic cells, solar photovoltaic in China is still a small market has lagged far behind the industry. Now, China's solar photovoltaic industry is a typical export-oriented sectors - raw materials and sales markets Sony PCGA-BP4V battery are mainly abroad. According to statistics, in 2006, China's primary energy consumption,  solar energy accounts for only 0.51 percent; in 2007, China's installed solar photovoltaic capacity was less than 1% share of the world, producing countries and very different position.



In addition, the application of solar photovoltaic and solar energy resources, China is also rich out of proportion. Chinese solar Sony PCG-Z505 battery energy rich region's land area and account for 2 / 3 or more years of radiation over 6,000,000,000 J / m, the surface each year to absorb the solar energy equal to about 1,700,000,000,000 tons of standard coal of energy, especially in the northwest, Tibet and Yunnan And other regions, Sony PCGA-BP71 battery is particularly rich in solar energy resources. Wan Gang Minister of Science and Technology predicted that if the Chinese use of the existing 20% and 2% of the roof area of the Gobi Desert and the region would allow the solar photovoltaic installed capacity of 22 million kilowatts in generating capacity of up to 2,900,000,000,000 kilowatt Time. Now installed capacity of less than one ten thousandth.



Solar photovoltaic barriers to the development of the domestic Sony VGP-BPL2 battery  market mainly from the high cost, high cost of power generation. At present, the cost of photovoltaic power generation in each unit of electricity at about 4-6 yuan, equivalent to about 10 times the power generation, and commercial applications are still a considerable distance.



But in the long run, solar photovoltaic, Sony VGP-BPS3 battery, Sony VGP-BPS5 battery or there are a number of comparative advantages. China's first home in the U.S. Nasdaq-listed solar PV companies - CSI Qu Xiao Hua, president of Art, said: "People often talked about solar power generation can only see the ultimate price of energy than conventional power generation to be as expensive, but very few To consider the use of traditional energy caused by the environmental cost of land, as well as the cost of energy for sustainable development potential if these are taken into account, solar photovoltaic in fact have a great advantage. "



Look forward to the support of state policies



"Renewable energy development" 11th Five-Year Plan "," China clearly put forward by the year 2010, renewable energy in energy consumption in the proportion of 10%, the total solar power capacity 300,000 kilowatts.



Many believe the industry, Sony VGP-BPS8 battery photovoltaic power generation due to the current high cost of power generation is still totally rely on market-driven, the photovoltaic industry will be difficult, so policy support to promote PV market has become the major driving force for growth, one of the important point is to proceed " Internet pricing "policies to improve the problem.



National Association of Industry and New Energy Chamber of Commerce executive vice president, Suntech Power Co., Ltd. Shi Zhengrong, chairman of an interview with reporters, said that starting as early as this area is Germany, in 2004 the implementation of the revised "tariff", Implementation of compensation for the purchase of electricity, Sony VGP-BPS9 battery according to the different forms of solar power, the government for a period of 20 years, different levels of subsidies. Compensation for the purchase of electricity from the introduction of German photovoltaic market has become a catalyst for growth, just a few years later, Germany won over Japan as the world's largest photovoltaic market. Despite the current financial crisis hit the world of the photovoltaic industry continuation of the policy thrust is still some strength still increasing government subsidies.



Although China passed the "Renewable Energy Law," and expressly stated that the "purchase price" and "the whole network assessments" of the provisions of the laws and regulations, but the implementation of the rules and regulations is not yet in place, Sony VGP-BPS10 battery do not have a strong operational. "Solar power is a new thing into concrete policy, how the Internet, how pricing, government, power companies, enterprises do not have experience, summed up the need to explore." Shi Zhengrong said.



However, China's photovoltaic power generation prospects, Shi Zhengrong is still full of confidence. He predicted that, Sony PCG-R505 battery through the upper reaches of the industrial chain of polysilicon prices and a decline in industrial technological innovation, Tak in 2012 is expected to achieve the photovoltaic power generation per 1 yuan money. He said: "When the cost of photovoltaic power generation with the same thermal power, we have reason to believe that the photovoltaic market will have unlimited room for growth."Photovoltaic cell production in the world
