Solar Panel Not Working? Here’s What You Need To Know

Solar power systems consist of several components, including solar cells, a solar array, and a solar inverter.

While solar power is a reliable and cost-effective source of energy, solar inverter problems can cause significant issues with your system's performance.

Therefore, it is essential to regularly inspect and maintain your solar power system, including the solar inverter, to ensure optimal energy production and cost savings.

Dirty Solar Panels

One of the most common reasons for decreased energy production from solar panels is dirty panels. Dirt and debris on the surface of the panels can block sunlight and reduce their efficiency. To prevent this issue, it is essential to regularly clean your solar panels. You can do this by spraying them down with water and wiping them with a soft brush or cloth.

Faulty Wiring

Faulty wiring can also be a reason for solar panels not working correctly. Damaged wiring can disrupt the flow of electricity from your panels to your home. If you suspect wiring issues, it is best to hire a professional electrician to inspect and repair the wiring.


Shading is another issue that can affect the efficiency of your solar panels. Trees, buildings, or other objects that cast shadows on your panels can reduce the amount of sunlight they receive, leading to decreased energy production. To avoid shading, it is important to place your panels in a location with direct sunlight and minimal obstructions.

Inverter Failure

The inverter is a critical component of your solar system that converts the DC energy produced by your panels into AC energy that can be used in your home. Inverter failure can lead to a complete shutdown of your system. If you suspect your inverter is not working, it is best to call a professional to inspect and replace it if necessary.

Battery Issues

If your solar panel system includes batteries, battery issues can also affect your system's performance. Old or damaged batteries can cause your system to shut down or not produce enough energy. If you suspect battery issues, it is best to contact your solar panel installer to troubleshoot and replace them if necessary.

Weather Conditions

Extreme weather conditions such as high winds, hail, or heavy snow can damage your solar panels and affect their performance. It is important to prepare for extreme weather by ensuring that your panels are installed correctly and securely. If you suspect damage from extreme weather, it is best to call a professional to inspect and repair your system.

Power Outages

If your solar panel system is connected to the grid, power outages can cause your system to stop working. This is because your system is designed to shut down automatically when the grid goes down to protect utility workers from electrical shocks. When the power comes back on, your system should start working again. If it does not, it is best to call a professional to inspect and troubleshoot the issue.

System Maintenance

Lack of maintenance can also cause solar panel performance issues. It is essential to perform regular maintenance, such as cleaning your panels and inspecting your system for any issues. This can help to identify and fix problems before they become more significant issues.

System Age

The age of your solar panel system can also affect its performance. Older systems may not be as efficient as newer ones and may require upgrades or replacement. If your system is over ten years old, it may be time to consider upgrading or replacing it.

Installation Issues

Lastly, installation issues can also cause solar panel performance problems. Incorrect installation can lead to shading, wiring issues, or other problems. If you suspect installation issues, it is best to contact a professional to inspect and fix the issue.
