Why are my solar lights not bright?

If you find that your solar lights are not as bright as they used to be, try changing the angle of the solar panel. Sometimes a slight adjustment can make all the difference.

Why does my solar charger not show at night?

This is a safety mechanism, the reason to still enable the output is to allow a system to self-recover from a battery low situation. Solar Chargers only show this error when there is solar power available and thus the device is ready to initiate charging. It does not show at night.

Why is my solar light not working?

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.

Do solar chargers need sunlight?

Sunlight is the lifeblood for any solar device. If a plant doesn't get enough light it can't photosynthesize and thrive. Similarly, solar devices need ample sunlight exposure to charge. If your solar charger's location is not getting enough daylight, you may need to move it to a sunnier location. Even the best batteries die after a while.
