Is now a large-scale commercial applications forward, solar power plant regulation Die from the previous kilowatt-class development to the current megawatt-class, solar cell manufacturing plant production capacity from hundreds of kilowatt-class to the current tens of megawatts to 100 megawatts. Countries around the world have developed PV development plans, and invested heavily in technology development and accelerate the industrialization process. The idea and principle of the use of temperature-difference semiconductors, thermionic, thermophotovoltaic, and direct thermal generation of disc-type or trough-type solar heat using alkali metal thermoelectric direct converters (AMTEC)

Table, but ultimately not practical, are in the research stage. China's solar photovoltaic industry compared with the advanced countries in the world, due to late start, regardless of the technical level, production capacity, application areas there is a big gap. Especially in the development of solar cells, production is still lagging behind the international level, as a whole is still in the production of small, narrow application, the product of a single, backward technology in the early stages. Beijing Institute of Solar Energy and the Institute of Electrical Engineering, Chinese Academy of Sciences assumed the key technology of solar thermal power generation project.

Solar street lamp advantages
The main advantages of solar street lights include: ① energy-saving, solar street light is the use of natural natural light, reducing the consumption of electricity; ② safety, municipal lighting, lighting may exist due to construction quality, material aging, power supply disorders and other reasons Security risks. Environmental protection, solar street lights without pollution, no radiation, in line with modern green concepts; ④ high-tech, solar energy, solar energy, solar energy, solar energy, solar energy, solar energy, solar energy, Street lights with intelligent controller to control, according to 1d in the natural brightness of the sky and people in a variety of environments need to automatically adjust the brightness of the brightness; ⑤ durable, the vast majority of solar cell production technology, are sufficient to ensure that 10 ⑥ low maintenance costs, in remote areas away from the town, in order to maintain or repair conventional power generation, transmission, street lamps and other equipment costs are high. ⑥ low maintenance costs, in the remote areas away from urban areas, in order to maintain or repair conventional power generation.
