Solar street lighting system
Working principles:
In the daytime, when the sunlight shines, the solar panel can generate electric energy and charging the battery through the controller based on photovoltaic effect.
At night, the working voltage and current continuously drop with the sunlight gradually weakening. When the working voltage is less than the set voltage of the controller, the controller starts a load. At this time, the solar light turns on.
When the setting time is up or when the environment lights are too strong, the controller stops the load automatically.
