Solar street lamp is an independent power generation and lighting system, that is to say, it generates electricity for lighting without connecting to the power grid. During the day, solar panels convert light energy into electric energy and store it in the battery. At night, the electric energy in the battery is supplied to the light source for lighting. It is a typical power generation and discharge system.
So how many years do solar street lamps generally use? About five to ten years. The service life of solar street lamp is not only the service life of lamp beads, but also the service life of lamp beads, controllers and batteries. Because the solar street lamp is composed of many parts, the service life of each part is different, so the specific service life should be subject to the actual things.
1. If the whole hot-dip galvanizing electrostatic plastic spraying process is used, the service life of the lamp pole can reach about 25 years
2. The service life of polycrystalline solar panels is about 15 years
3.The service life of LED lamp is about 50000 hours
4.The design service life of lithium battery now is more than 5-8 years, so considering all accessories of solar street lamp, the service life is about 5-10 years.
The specific configuration depends on what kind of materials are used.
