Solution: Repair the light source or replace the light source.
2. the solar panel is damaged
Connect a multimeter to test the voltage of the solar panel without any load. Usually the system operating voltage is 12v, which is higher than 12v under normal circumstances. Only when the voltage is higher than 12V can the battery be charged, if it is lower than 12V The battery cannot be charged. The solar street light system cannot work or the working time is not enough.
