The lighting time is short. After using solar street lights for a period of time, even if there is sufficient light, it is possible that the lighting time may be short, and it is not possible to provide lighting normally on rainy days. Most likely, there is a problem with the battery, and its storage capacity has decreased, which naturally leads to insufficient storage. It is necessary to replace ...

Solar photovoltaic power generation: When sunlight shines on some special materials, it can cause the movement of electrons in the materials, forming a potential difference. Solar photovoltaic power generation is based on this principle, using solar cells to directly convert solar energy into electrical energy. Solar photovoltaic power generation system is a new type of power generation system tha...
