15W led solar garden lighting system

working principle

The solar street light relies on solar energy, which is clean, endless and environmentfriendly. 

The system is mainly composed of solar panel, light source, controller and battery. 

In daytime, when there is sunshine, the solar panel can convert the solar energy to electric energy and 

store it in the battery. 

At night or rainy or cloudy condition, the battery shall supply power for normal lighting. 

The controller can judge the brightness of daylight and automatically switch on the light. 

The whole process is operating in completely automatic mode, without human action.
