Should I Get My Solar Panels Cleaned?

If you have solar panels installed on your home in Somerset, you may wonder whether they need cleaning to keep them working properly.

The short answer is: usually not very often, but sometimes it does help.

Do Solar Panels Get Dirty?

Over time, solar panels can collect dirt such as:

• Dust and pollen
• Bird droppings
• Leaves and debris
• Moss in shaded or rural areas

In towns and villages around Wells, Glastonbury and rural Somerset, panels can get dirtier than expected, especially if your home is near trees or farmland.

Does Dirt Affect Performance?

Yes, but usually only slightly.

A light layer of dirt will not stop your solar panels from working, but heavier build-up can reduce how much electricity they generate. Bird droppings and thick debris are more likely to block sunlight and affect output.

For most homes, the loss is small, but over time it can add up.

Does Rain Clean Solar Panels?

In many cases, yes.

UK rainfall often helps wash away dust and light dirt, which means most solar panels stay fairly clean on their own. This is why regular cleaning is not essential for every household.

However, rain doesn’t always remove stubborn dirt, moss or bird mess.

When Is Cleaning Worth Considering?

You may benefit from cleaning your solar panels if:

• Your panels look visibly dirty
• You live near trees or fields
• There is moss growth on or around the panels
• Your system’s output has dropped unexpectedly

A simple visual check from the ground is often enough to decide whether cleaning might help.

Can I Clean Them Myself?

It’s not recommended to clean solar panels yourself, especially if they are on the roof.

Using the wrong equipment or climbing onto a roof can be dangerous and may damage the panels. If cleaning is needed, it’s best done safely by professionals with the right tools.

The Bottom Line

Most solar panels in Somerset do not need frequent cleaning. Rain usually does the job, and light dirt won’t cause major problems.

However, if panels are heavily soiled or performance has dropped, a professional clean can help restore efficiency and protect your investment.
