Solar power station type solar archaize street lamps is introduced

The light of the photovoltaic power generation is to use semiconductor interface will be born v effect in a technology light energy directly into electrical energy. The technology of the key element is the solar cell. Solar cells after a series of packaging protection can form a large area of solar energy battery components

photovoltaic effect of photovoltaic power generation is to use semiconductor interface technology converts light energy into electrical energy. A key part of the technology is the solar cell. Solar cells in series after packaging protection, form a large area of solar cells, modules, photovoltaic power generation device is composed of power controller with other parts. Solar power has two kinds of methods, one is light solar power; Another is hot ndash lightweight asphalt. Direct conversion of electric power. ( 1) Light ndash ndash electricity conversion method using solar radiation produced by thermal power generation. Usually, the solar collector will absorb heat energy is converted into industrial steam, and then to drive a turbine to generate electricity. The previous process is light ndash thermal conversion process; After a process is hot ndash electric energy conversion process is the same as the normal thermal power. The disadvantage of solar thermal power generation is the low efficiency and high cost. It is estimated that the amount of at least 5 ~ 10 times that of ordinary coal-fired power plants. ( 2) Lightweight ndash electricity direct conversion method this method solar radiation directly into electricity by photovoltaic effect, namely light; Electrical energy conversion is the basic equipment of solar cells. The solar cell is a kind of solar energy directly into electricity by photovoltaic effect. This is a semiconductor photodiode. When sunlight on the photodiode, photoelectric diode to convert solar energy into electrical energy and generate an electric current. When many cells in series or in parallel, they can become the solar array output power is relatively large. The solar cell is a promising new type of power supply, and permanent, clean and flexibility to three big advantage. Solar energy service life is long, only in the case of the sun, can one-time investment for long-term use. Compared with thermal power and nuclear power, solar cells will not cause environmental pollution. Road signal light pole
