The solar panel is the central part of the solar street lamp, which converts the radiant energy of the sun into electric energy and then transfers it to the storage battery for storage. There are mainly three kinds of useful solar panels: monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells. It is best to choose polycrystalline silicon solar cells in areas with sufficient sunlight, monocrystalline silicon solar cells in areas with relatively insufficient illumination, and amorphous silicon solar cells in areas with insufficient outdoor sunlight.

2. battery?

The main function of storage battery is to store electric energy to compensate the unstable input energy of solar photovoltaic power generation system. Batteries mainly include lead-acid batteries, nickel-hydrogen batteries and nickel-cadmium batteries.

3. Special controller for solar street lamps?

In the solar street lamp, an essential component is the solar controller. The primary function of the solar controller is to maintain the battery, and to avoid deep charging and discharging of the battery by limiting the charging and discharging conditions of the battery. In places with large temperature difference, the solar controller also has the function of temperature compensation.

4. Luminous body?

Luminous body is an important goal for the normal operation of solar street lamps. Solar street lamps usually use LED, low-voltage sodium lamp and low-voltage energy-saving lamp. At the same time, LED lamps have long service life and low working voltage, and are the most widely used luminaries in solar street lamps.

5. lamp pole and lamp shell?

The height of the lamp pole really depends on the width of the road, the lighting standard of the road and the distance between two lamps. The requirements for the lamp shell are not very high, and the first thing is to save energy and be more useful.
