We know that the solar street lamp is composed of solar panel, solar controller, battery pack, light source, lamp pole and lamp shell. Among these components, the lithium battery currently used by the battery pack will have a service life of about 5 years, and the performance will decline after that. The service life of LED lamp source is about 50000 hours, about 5 years, and the service life of solar panel is 20 years, As long as it is not artificially damaged, it will not be easy to damage. The solar controller also has a service life of 8-10 years, and has the functions of overshoot, discharge and lightning protection.
Therefore, the service life of solar street lamps is a great benefit for the new countryside. After installation, there is no need for electricity. Solar street lamps use solar energy as power supply to provide road lighting at night. They can be used as long as the sun is sufficient.
