The solar energy is converted into  electricity stored in the battery by the solar panel through the day time. The  solar panel voltage will decrease gradually in the dark time. When the solar  panel voltage is lower than stipulated voltage, the controller will make the  battery supply electricity to load; when the day become bright, the solar panel  voltage increase gradually. After the voltage is lager than stipulated voltage,  the controller will stop the battery supplying the electricity to load.
 This is the principle of solar street  light.
