Explanation of working principle of solar street lamp:
(1) Under the control of intelligent controller, solar panels absorb sunlight and convert it into electric energy. During the day, the solar cell module charges the storage battery, and at night, the storage battery supplies power to the LED light source to realize the lighting function.
(2) The 2)DC controller can ensure that the battery pack is not damaged by overcharge or overdischarge, and has the functions of light control, time control, temperature compensation, lightning protection and reverse polarity protection.

Solar street lamps do not need to lay underground cables, nor do they need to pay for lighting electricity. The key components of solar garden lights, such as solar panels, intelligent controller for solar DC street lamps, maintenance-free batteries, lighting lamps, etc., have all passed the photovoltaic product certification of National Development and Reform Commission /GEF/ World Bank.
