One of the most common reasons why your solar light isn’t working is the wire between the solar panel and the battery. This wire is responsible for transferring the generated electricity from the solar panel to the solar battery — charging it in the process. If this wire is broken, then your batteries won’t charge no matter what you do.
Most of the outdoor solar garden lights come with ON/OFF button, and that button needs to be turned ON. In many cases this simple thing is ignored by many people and this is one of the main reasons why your solar light isn’t working as expected.

If your outdoor solar lamp has stopped working, the rechargeable batteries might need replacement. You can test the lights with a regular battery to ensure if the rechargeable battery is at fault. A faulty battery could either not get enough charge or be unable to hold it for long.
Regular maintenance, such as cleaning the solar panels and checking for obstructions, can prevent many of these issues. When only half of a solar light string works, it could be due to individual bulb issues or battery charging problems. If solar lights are not working after rain, it may indicate water damage or short-circuiting.
Most solar lights have a built-in sensor (usually a photoresistor) that acts like an automatic switch, keeping the lights off during the day so the battery can charge and turning them on when it gets dark. But if the sensor isn’t working, it might not “know” when it’s dark, so the lights stay off at night.
To fix solar lights not working, check and remove the battery pull tab, replace or deep charge the batteries, repair any damaged wiring, clean the solar panels, and ensure they’re positioned in direct sunlight. How Do You Reset a Solar Light?
