Solar power, how high the threshold


Experts predict Toshiba Laptop Battery that the next 20 to 30 years, the global energy mix will be a fundamental change in the 50s of this century, new energy and renewable energy will account for the entire energy constitutes 50%. Solar energy as a great potential for development of new and renewable sources of energy has long been a concern all over the world, China has also done a lot of research, it is regrettable Laptop Battery that many years later, solar power seems to have been in people’s is a concept of distance and symbols, you can feel better but it shall not close, then the threshold of solar, how high, delays in the industrialization of disease in the end there, this new energy, one of the protagonists Ho gorgeous debut when are people want to solve the… …

How much solar energy

Under the authority of the world’s energy analysis, the world has proven a major fossil fuel reserves and production can not be optimistic about the world. Length of remaining recoverable oil is only 41 years, their share of world total energy consumption of 40.5%; number of years of remaining recoverable natural gas 61.9 years, their share of world total energy consumption of 24.10%; number of years remaining recoverable coal 230 years, their share of world total energy consumption by 25.2%; number of years remaining recoverable uranium 73 years, their share of Toshiba Satellite A100 Battery world total energy consumption by 7.6%; other hydraulic their share of world total energy consumption of 2.6%.

Traditional fuel energy is being reduced day by day, energy issues can not be ignored have become global issues. Search for new energy sources, has become a top priority. They soon focused its attention on the people around us in the renewable energy, wind energy, solar, geothermal, biomass power generation … … the new alternative to traditional energy sources have become new targets one-time energy. Wealth of daily solar radiation is inexhaustible and pollution-free, low-cost, free use of human energy and vision to become the first Toshiba Satellite A10 Battery to incorporate the best choice for people. Solar energy per second to reach the ground up to 800,000 kilowatts of energy, if the Earth’s surface to 0.1% of solar energy, change rate of 5 percent, generating an annual output of about 5.6 × 1012 kilowatt hours and the equivalent of the world’s energy consumption about 40 times. Our country is rich in solar energy resources in the world. Desert area of China has 1.08 million square kilometers, mainly distributed in the light of the northwest region is rich in resources. 1 sq km area that can be installed 100 megawatts of photovoltaic arrays, generating 150 million a year degrees; 1 percent if the development and utilization of desert, you can issue the equivalent of China’s electricity consumption throughout the year in 2003. At present, China’s northern, coastal, and many other areas Toshiba Portege 4000 Battery, the volume of annual sunshine hours in 2000, Hainan is reached more than 2400 hours, the solar energy resources to name but a few large countries.

Such a huge energy reserves, we have developed is the situation be?

China’s solar energy industry into the environmental protection industry processing plants abroad

Solar cells can convert solar energy into DC energy, the production of solar PV industry chain is the most crucial aspect. The world’s most widely used solar cells are crystalline silicon solar cells, crystalline silicon solar cells production of raw materials - high-purity polysilicon has a severe shortage in our country, the vast majority of the need to rely on imports. According to experts in the Chinese Academy of Engineering survey, in 2005 the demand for China’s polysilicon for 3800 tons, of which the demand for photovoltaic industry 2691 tons, while in 2004 the output of polycrystalline silicon in China only 60 tons, even if all the supply of photovoltaic industry, but also only 2.6% of market demand, and the rest can only rely on imports. To form the photovoltaic industry in China well-known “two out” phenomenon: the raw materials for more than Toshiba PA3591U-1BRS Battery dependence on imports, exports more than九成. The reason is that the face of high cost of solar cells, temporarily unfit for wider use of home. Caused by the direct cause of this phenomenon is that technology can not keep up, raw material control.

Solar PV cells manufacturing chain as follows: quartz sand - polysilicon - cut into a silicon (or into a monocrystalline silicon) - batteries and battery components (individual cells can not generate electricity), then components portfolio, and finally installed in projects for electricity generation. Product monopoly of transnational corporations, it is polysilicon. Seven companies around the world, controlled almost all the high-purity Toshiba PA3506U-1BRS Battery polysilicon sales and manufacturing, they do not cooperate, or joint ventures, technology is completely closed.

In fact, the upstream poly-silicon raw material quartz sand is no shortage in our country. Polysilicon many overseas companies are direct procurement from China. However, Chinese enterprises for the silicon purification technology, has been the lack of progress. The’90s, there were more than 40 companies in the study of small poly-silicon technology, but is not a company can take on large-scale production of polysilicon. Technology can not break through the bottleneck, there will be others to complete, so even if there are no raw materials, technology, and can only be a low-cost processing of foreign environmental protection Toshiba PA3291U-1BRS Battery industry. Thus led to the solar industry, I have been hesitant. Solar power generation cost and the cost of traditional coal-fired power generation than the current purchase price of solar power is about 3.5 yuan / kilowatt-hour, there are the ordinary generating units of the purchase price, about 10 times the cost is so high dell inspiron b120 battery,dell inspiron b130 battery, it is clear there is no universal possible, so we have no alternative but to enjoy the warm sunshine at the same time, watching a lot of energy in the close loss, but could do nothing about it!

Number of legs to walk, to find a new way out Toshiba PA3356U-1BRS Battery, for China’s solar power generation

In order to make solar power closer to the people at an early date, the domestic research institutions have done a lot of work. Recently, the Japan Science and Technology Agency to take the lead, China, Wuhan Polytechnic University, Tsinghua University, Shanghai Institute of Ceramics, and Japan Aerospace Exploration Agency, Japan Aerospace Technology Foundation, Toshiba and Tohoku University in Japan to participate in solar power generation solar thermal compound system will continue to conduct joint development and will be the beginning of April this year in China’s desert area in Inner Mongolia for a model test the durability of the year, and gradually moved to Toshiba PA3250U-1BRS Battery one run. Solar thermal power generation system is a composite of visible light and ordinary use of solar energy systems useless or harmful infra-red system for the new generation. The system through a special lens to gather sunlight for the visible separation of light and infrared, visible light, after reflection of solar cells for small, infrared, through the special lens used in electric power generation module. At the same time as a result of the use of the visible and infrared sources of 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%. Because there is no removable parts, is a maintenance-free power generation methods, applicable to the desert area. The system to support the western region as the “bright work” part of China’s western region will be 23 million families with a lack of electricity Toshiba PA3395U-1BRS Battery power.

There are news in recent days, China University of Technology developed a new type of Tingri mirror, can effectively track the sun’s rotation, which makes use of solar power generation than coal-fired electricity generation is expected to lower internal cost. This mirror mirror Tingri to any position of the incident sunlight, can be effectively eliminated by the mirror caused by deficiencies in the design of Toshiba PA3399U-1BRS Battery aberration that can effectively track the sun’s rotation, the control system can usually Tingri by the mirror reduced to only two-dimensional control required for one-dimensional control. Condenser as a result of the cost of solar energy a significant reduction in the human will be more than the coal-house low-cost electricity.

It can be seen that through the efforts of solar power generation in China is not tight in the power of a new energy concept of speculation over the years not only done the protagonist of the situation debut will be the past, solar energy as the most potential and most resource-rich new renewable energy inspiron e1405 battery,dell inspiron e1505 battery, its large number of days used in power generation Toshiba PA3084U-1BRS Battery will not tell us to wait very long!
