The principle of solar street lamp power generation
Nov 02, 2017

Solar photovoltaic power generation system is the use of photovoltaic effect of the principle of solar cells can be directly converted into solar energy into electricity. The solar cell is the smallest unit used for photoelectric conversion. Its size is about 4 square centimeters to 100 square centimeters. Solar cell operating voltage of 0.45 a 0.50 volts, generally can not be used as a separate power supply. Will be able to drum cells in series, parallel and packaged, it becomes a solar cell components. Its power from a few watts to several hundred watts, can be used alone as a power supply. Solar cells and then through the series, parallel and installed in the bracket, it constitutes a large solar cell array. It can output hundreds of watts, where the kilowatt or greater power, is the power plant of photovoltaic power plant. Commonly used solar cells are mainly silicon solar cells. There are three commercially available silicon solar cells in the world: monocrystalline silicon solar cells, polysilicon solar cells and amorphous silicon solar cells.
