Solar Lights Not Working After Rain- Best Solutions

Is it raining there and your solar lights are not working? Don’t worry! Here are some solutions to your problems.

If your solar lights are not working after rain there is a possibility that water build-up can be inside the solar lights. This water can damage the internal circuit. You can check this by removing the upper head of the solar lights and look whether there is water or not inside the solar lights.

Why Do Solar Lights Not Working After Rain

Generally, solar lights use outdoors, so they have built-in resistance from the rain. But there may be possibilities that the solar lights stop working after rain. Some of the reasons for not working solar lights are as follows:

Reason 1: Rain-Water Has Flowed Inside the Solar Lights

Generally, rain doesn’t harm Solar Lights, because solar lights built-up in such a manner that they can resist rainfall. But there is still a possibility that rainwater has flowed inside the solar lights and your solar lights suddenly stop working after rainfall.

Reason 2: Improper Installation of The Solar Lights

Due to poor and improper installation of the solar lights, rainwater flows inside them. If the solar lights don’t properly install, due to the wrong placement angle, the rainwater can make its path to go inside the solar lights. This rainwater can damage the internal circuits of the solar lights.

Reason 3: Wiring Breakage Due To the Heavy Rainfall

If there is heavy rainfall, it can damage or break the wiring of the solar unit. Heavy rainfall can also be the reason that your solar lights are not working.

Reason 4: Absence of any Protected Sheet On Solar Lights

The solar lights should be covered by a protected sheet or any plastic cover, so solar lights can be protected from water or rainfall. If the solar lights are not protected rainwater can flow inside the solar lights and your solar lights don’t work after rain.

Solar Lights Not Working After Rain- Reasons and Solutions

Reason 5: The Sensor of the Solar Light Has Broken

In automatic solar lights, there is a sensor that detects the dark and automatically turns on the solar lights at night. And it senses the daylight and automatically turns off the solar lights in the daytime. If the sensor has broken due to rainfall, your solar lights will not work after rain.

Reason 6: Shortage Of Direct Sun-Light/ Cloudy day

A cloudy day can also be the reason that your solar light is not working. On a cloudy day, the sun doesn’t rise with its full sunshine, and the solar lights or panels are not getting enough sunlight for proper function.

Reason 7: Dirty Solar Panels

There may be other reasons that can cause the non-functioning of the solar lights. Dirty Solar Panels can also be the reason. If the panels are dirty they cannot absorb sunlight.

Solutions for Not Working Solar Lights After Rain

If your solar lights are not working after rain, some solutions for your problem are as follows:

Solution 1: Install The Solar Lights Properly

Take great care during the installation of solar lights. If the adjustment angle of solar lights is not correct there is more than a 90% chance that rainwater flowed inside the solar lights. Adjust the solar lights in such a way that they can be protected from rainwater.

Solution 2: Wipe Out Rainwater Inside the Solar Lights

If rainwater accidentally flowed inside the solar lights, it can easily wipe out with a dry cloth by removing the panel head. Cover it again when the water dried out.

Solution 3: Check Wiring After Rain

Must Check the wiring after rainfall and make sure that there is no breakage in the wiring. If wiring breakage occurs, your solar lights will not illuminate after rain.

Solution 4: Check Light Sensor After Rain

You must check the solar light sensor after rain. If the light sensor breaks after rain it will not detect light and will not automatically illuminate solar lights after rain.

Replace the Sensor, if the sensor has broken.

Solution 5: Clean The Solar Panels

You should regularly clean the solar panels. You can follow the given instruction to clean the panels.

  • Make a cleaning schedule for the solar panels and must follow the schedule.
  • Turn off the panels before cleaning.
  • Clean the panels with a soft cloth.
  • You can use soap and water to clean the panels.
  • Distilled water can also be used for cleaning panels.
  • Call the professional, if you are afraid of cleaning by yourself.

Can Solar Lights Charge on a Cloudy Day?

Although the sun is the key to charging solar panels, however, solar light can charge on a cloudy day, but not like that as on a sunny day.

What Happens If The Solar Light Gets Wet?

The little moisture doesn’t harm the solar lights, because solar lights are water-resistant. But it is better to dry out the water.

Should We Turn OFF Solar lights During Rain?

No, the solar lights can remain turned on during the rain because they are water-resistant.
