What to do when solar street lights suddenly stop working? There are several reasons why solar street lights may not illuminate. Below, we provide insights from a manufacturer of solar street lights.
1. Damage to the solar panel
This situation is quite rare, as solar panels generally have a long lifespan. However, no product is perfect, and it is possible that the solar street light system may not function or may not operate long enough.
Solution: The only option is to replace the solar panel.
2. Failure of the LED light source
This is a common cause, as the LED light source may fail due to natural or human-induced damage, leading to the solar street light system not functioning. When turned on, the light may not illuminate or flicker.
Solution: Inspect or replace the LED light source.
3. Incorrect polarity connection of solar battery
First, check if the positive and negative terminals of the panel are reversed.
After installation, the solar street light system may only light up once, and the light will not illuminate when the battery is depleted.
Solution: Switch the positive and negative terminals of the solar battery.
4. Aging or disconnection of wires
The solar street light system may not function correctly, and the LED may not illuminate or flicker.
Solution: Reconnect or replace the wiring.
5. Controller error
The control panel has no buttons, so a handheld terminal may need to be added or connected to a computer via a data cable for software reset. Assistance from the supplier may be necessary.
The solar street light system may not operate correctly. The LED lights may not illuminate, nor stay on long enough at night, or may fail to turn on at dawn.
Solution: Thorough inspection of the controller’s settings, programs, and hardware is required, or direct reset and replacement of the controller.
6. Failure of the constant current source
Eliminate issues with the system restarting the bulb for proper operation.
The solar street light system may not function, and the LED lights may not illuminate or flicker.
Solution: Inspect or directly replace the constant current source.
7. Human-induced damage to the solar street light system hardware
This situation is commonly serious, leading to the solar street light system not functioning normally.
Solution: In this case, it is necessary to repair and identify the damaged hardware of the solar energy-efficient light, then fix or replace the damaged components.
