- Controlador: The controller is what receives the signal and controls when the light should light up. If you find that the indicator light on the controller doesn’t light up, you can try to rewire the controller or replace it.
- Sensor de luz: The light sensor can change the resistance value according to the brightness of the surrounding light. But sometimes it will make the wrong judgment. You can try to reduce its sensitivity or replace it.
- Painel solar: The controller makes the light light up when the voltage is low. And the more light solar panels receive, the higher the voltage. So there may be something wrong with the panel.
