1 Solar street light works

Solar street light using solar cell photovoltaic effect of the principle of daytime solar cells to absorb solar energy to generate energy, through the controller stored in the battery, when the night falls or lighting around the lamp is low, the battery through the controller to the power supply set by the controller Time after the cut off.

2 composition of solar street light

Solar street light mainly by the following components: solar modules, component bracket, solar controller, battery, light source, light pole (including lamps) and so on.

Polycrystalline silicon solar modules.

Solar panels are the core of solar street light, solar lighting is the highest part of the value. Its role is to convert the sun's radiation capacity into electricity, or sent to the battery stored.

In many solar cells in the more common and more practical monocrystalline silicon solar cells, polysilicon solar cells and amorphous silicon solar cells and other three. In the sunny sunshine good sun and the east, the use of polysilicon solar cells as well, because the polysilicon solar cell production process is relatively simple, the price is lower than the single crystal. In the rainy days are more, the sun is not very adequate in the southern region, the use of monocrystalline silicon solar cells as well, because the monocrystalline silicon solar cell performance parameters are relatively stable. Amorphous silicon solar cells in the case of outdoor sun is not good, because the amorphous silicon solar cells on the sun light conditions are relatively low.

The entire solar cell is encapsulated in a preferred EVA transparent film between the surface tempered glass and the multilayer wear resistant polymer backplane. Anodized aluminum frame is used around the assembly to protect the assembly and increase strength.

Polycrystalline silicon battery PV module quality process quality, in full compliance with international standards IEC61215 test requirements and through certification. Solar components can withstand a variety of adverse weather conditions, including dramatic changes in temperature, moisture, strong winds and hail impact.
