6 Useful Solar Panel Maintenance Tips

If you have solar panels installed on your home, it’s important to keep them maintained properly.

Failing to do so can result in decreased efficiency and lower solar output.

In this blog post, we will discuss six solar panel maintenance tips that will help you keep your system running smoothly.

Inspect your solar panels for damage every month

Look for cracks, loose connections, or other signs of wear and tear.

If you notice any damage, contact a solar panel technician to have it repaired.

By inspecting your solar panels regularly, you can catch problems early and prevent them from getting worse.

Cracks in solar panels can allow water and dirt to seep in, which can damage the cells and decrease efficiency.

Loose connections can cause arcing and heat build-up, which can lead to fires.

These are all things that you want to avoid, so make sure to inspect your solar panels every month.

Clean your solar panels at least twice a year

Dirt and dust can accumulate on the surface of solar panels over time, which can reduce their efficiency.

Solar panel manufacturers typically recommend cleaning solar panels twice a year – once in the spring and once in the fall.

You can clean solar panels yourself with a hose and a soft brush.

If you have a large solar panel array, you may want to hire a professional solar panel cleaning company to do the job for you.

Check the inverter to make sure it’s functioning properly

The inverter is what converts the DC current produced by solar panels into AC current that can be used in your home.

If the inverter isn’t functioning properly, you won’t be able to use any of the electricity that your solar panels produce.

To make sure the inverter is working correctly, check the indicator light on the front panel.

It should be green if it’s functioning properly. If it’s not, you may need to have the inverter serviced.

Tighten all connectors and electrical wiring every six months

Over time, connectors and electrical wiring can become loose due to vibration or thermal expansion and contraction.

This can cause arcing and heat build-up, which can be dangerous.

To prevent this from happening, make sure to tighten all solar panel connectors and electrical wiring every six months.

Replace any broken or cracked tiles on the solar panel array

If your solar panels are mounted on a roof, they’re likely covered with solar tiles.

These solar tiles protect the solar panels from weather damage and help keep them cool.

If a solar tile is broken or cracked, it needs to be replaced as soon as possible.

Broken or cracked tiles can allow water and dirt to seep in, which can damage the solar panels.

They can also cause shade problems, which will reduce the solar output of your system.

Keep trees trimmed so they don’t shade your solar panels

If you have trees near your solar panel array, make sure to keep them trimmed.

Over time, tree branches can grow and shading can become an issue.

Shading can reduce the solar output of your system by up to 30%.

By keeping trees trimmed, you can prevent shading and maintain optimal solar output.

Leaves and other debris can also accumulate on solar panels, which can reduce their efficiency.

Make sure to keep the area around your solar panel array clean and free of clutter.


Maintaining your solar panels is an important part of ensuring that they continue to produce energy at their peak efficiency.

By inspecting your panels for damage every month, cleaning them regularly, and checking the inverter function, you can avoid costly repairs and keep your solar array running smoothly.
