Solar panel maintenance

A clearer surface for your solar panels

Solar panels are exposed to dust, pollen, bird droppings, and other outdoor debris. Buildup can block sunlight from reaching the panel surface.

Our solar panel cleaning service removes surface contamination as part of your property’s ongoing maintenance. Results depend on the condition of the panels, the type of buildup, and your system—we do not promise a specific increase in energy production.

A considered approach

Cleaning planned around your property

Every installation is different. Before scheduling, we review the panel location, access, approximate panel count, and visible buildup to determine the appropriate cleaning approach.

Helpful answers

Frequently asked questions

How often should solar panels be cleaned?

The right frequency depends on your surroundings, visible buildup, and the panel manufacturer’s recommendations. Nearby trees, dust, and bird activity can affect cleaning needs.

Will cleaning increase my energy production?

Removing buildup may help when dirt is blocking sunlight. Any change in output depends on the system and conditions, so we do not guarantee a percentage increase.

Can you clean every rooftop installation?

Service depends on safe access, roof conditions, and the panel layout. We review those details before confirming the job.

Can you provide an estimate from photos?

Photos can help us assess the panel count, condition, and access. Some properties may require more information or a site visit.

Can I request window or gutter cleaning too?

Yes. Let us know which services you need, and we can review them together when preparing your estimate.
