Working Principle of SOKOYO Solar Street Lights

During the day time, solar panels generate DC power, it passes through the controller to change the battery, when the night comes the controller detects no current coming from the panels then it gives an order, to the LED lamp to turn ON, and the lamp will turn OFF again once the controller detects power current coming from the panel again on the next day.

In case of a non-sun rainy day while no current coming out of the panel for the whole day, the controller was pre-set to turn ON the lamp for a certain amount of hours using the backup capacity of the battery which could be determined upon customer request.
