In today's society, we can see solar street lights everywhere. This paper first introduces the components of solar street lights, then elaborates the working principle and advantages of solar street lights, and then introduces the application field and application principles of solar street lights.
The working principle of the solar street lamp is to convert the solar energy into electricity so as to achieve lighting. On the top of the street lamp is a solar panel, also known as a photovoltaic module. During the day, these photovoltaic modules made of polysilicon convert the solar energy into electricity and store it in the battery. It absorbs solar light and converts it into electricity.
