Resource saving is the main theme of this era. Taking street lamps as an example, they play an important role in people's night life. Without them, people will not have a good night. Solar streetlights give people a symbol of safety and warmth. With solar streetlights at night, walking, chatting, sports, playing cards and square dancing make people's life more colorful.

　　Solar street lamp takes solar energy as energy source. When it comes to solar energy, of course, we should think of its huge energy. People who use solar energy don't have to worry about the exhaustion of light energy, and solar energy is very easy to obtain, which contains infinite power. As long as it is reasonably used, it is inexhaustible energy, which provides a prerequisite for the development of solar street lamp.

　　Solar streetlights use solar panels to gather sunlight and absorb solar energy in an all-round way. As long as there is a little light in the daytime, these panels can capture and gather enough energy to convert the solar energy into electric energy. As soon as the sun sets, these streetlights will be turned on in time for illumination with enough brightness to send light and safety for people's travel at night .

　　The use of solar street lamp can get rid of the control and bondage of electric power, avoid the unstable brightness and power failure caused by the unstable AC power, and will not worry about the power supply difficulties caused by the low voltage during the peak period.
