The High Lumen Street Light Housing smanufacturer hares that the working principle of solar street lights is actually not complicated, rather simple:

Solar street lights are solar panels made using the principle of photovoltaic effect. During the day, solar panels receive solar radiation energy and enter it into electrical output.
The charge and discharge controller is stored at night and the lighting is gradually reduced to about 10lux. The open circuit voltage of the solar panel is about 4.5V. After the charge and discharge controller detects the voltage value, the battery will be discharged to the light source. 8 hours After the battery is discharged, the charge and discharge controller ends the battery discharge. The main function of the charge and discharge controller is to protect the battery.

Through the above introduction, 50w Street Light Housing Manufacturers hopes that you can simply refer to the content of this article in future use.
