There are also street lights in some cities that want to install solar energy, but there are already city circuit lights on the roads and they don't want to abandon them, that is, they want lights like city electricity plus solar energy. It is precisely because people have this demand that they can promote the development of social technology, and gradually developed street lights that meet such requirements, that is, commercial power complementary solar street lights. On the one hand, the use of complementary solar street lights can meet the requirements of urban road lighting, and on the other hand, it will not cause waste of resources. This is the best advantage of the complementary combination of solar photovoltaic power generation and commercial power generation in road lighting. . In some less demanding occasions, the lights on the road are allowed to go out for a certain period of time. The complementary solar street lights of the mains can be switched into the mains with a delay, or it can be controlled by a timer according to the season or the ambient temperature. Mains. When the sun is enough, we can also use solar energy instead of using city electricity, which is convenient and easy to use.
