When using solar lights, it is inevitable that the lights will not light up. So what causes the solar lights not to light up? Let’s analyze the reasons why the solar lights are not on, and look at the related maintenance methods.
What is the reason why the solar light does not light up?
1. Reasons and maintenance methods for solar lights not working
1. The light source is damaged
If the solar street light does not light up, it may be due to natural or man-made damage to the light source, resulting in the solar street light system not working, turning on and off, flickering and so on.
Maintenance method: Check and repair the light source or replace the light source.
2. The solar panel is damaged
When there is no load on the solar panel, connect a multimeter to test its voltage. Generally, the operating voltage of the system 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, which means that the solar street light system cannot work or the working time is not enough, resulting in the solar light not working
Maintenance method: replace the solar panel.

3. The positive and negative poles of the solar panel are reversed
The solar garden light system will only light up once after installation, and the solar garden light will never light up again when the battery runs out. Then, it may be that the positive and negative poles of the solar panel are reversed, which may cause it.
Maintenance method: Replace the positive and negative poles of the solar panel.
2. Other troubleshooting methods of solar lamps
How to repair and replace solar lamp battery:
1. Remove the controller.
2. Dig a hole and take out the battery.
3. Thread the correctly matched new battery cable, and connect the cable according to the original wiring method.
4. If the lead-acid battery is replaced with a lithium battery, professional technical engineers are required to match the battery voltage and capacity, and then replace the dedicated controller and charger for the lithium battery. Install and debug according to the correct wiring method before it can be used normally.
