Working Principle
1. LED solar street light relies on solar energy, which is clean, endless and environment-friendly.
2. The system is mainly composed of solar panel, light source, controller and free-maintenance battery.
3. 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 cloud condition, the battery shall supply power for normal lighting.
4. 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.
Application
A. Highway
B. City main road
C. School campus road
D. Sidewalk
E. Pathway
F. Farm & ranches lighting
G. Villa lighting
H. Landscape lighting - park, square etc.
The below points of solar street light are required for design and quotation:
1. Where is the final installation place (Country & City name)? Or tell us the latitude and longitude of lighting place.
The solar radiation will be checked according to the installation place to ensure the lighting time,
And save the cost at the same time
2. Lighting time per night & backup rainy or cloudy days?
The lighting time usually is 8 hours, 10 hours or 12hours, or choose half power design according to actual conditions.
Besides, how many backup days under rainy or cloudy weather will be required too.
3. Light pole height, and pole style?
Please choose your favorite pole style in our solar street lights, and tell us the pole height you need.
Solar street lights usually adopt light poles from 5M-10M.
4. The power of light source?
The light sources for solar street lights are usually 18W~120W LED.
