Why is cleaning your rooftop solar panels so important?
Many people assume rain is enough to wash the dirt off their roof. Rain does wash away some dust and pollen, but stubborn soiling such as bird droppings, accumulated dust, industrial fallout, moss and algae stays put. Even a small amount of dirt can mean 5 to 10% less energy output, and that loss only grows if you never clean the panels.
Regular cleaning also extends the lifespan of your installation. A clean panel performs more consistently and lasts longer. And by removing dirt build-up, you prevent hotspots: areas where dirt or minor damage causes extra heat, leading to permanent damage over time. Having your rooftop installation cleaned is a smart investment in both yield and longevity. Read more about solar panel cleaning.
How often should you have your rooftop solar panels cleaned?
That depends on the surroundings. Do you live in a city with a lot of fine dust, in a farming area with pollen and fertiliser in the air, or close to the coast, where salt and sand add extra soiling? Then your installation will get dirty faster.
In general, we recommend having your panels cleaned every one to two years. In heavily polluting conditions, such as intensive farming or industry nearby, every six months is better. Can you see dirt, streaks or deposits on your panels? Then get in touch with us for targeted advice.

The benefits of professional cleaning
- 01
Higher yield
Various studies show that a clean can improve yield by anywhere from a few percent to as much as 15%, depending on how dirty the panels are.
- 02
Longer lifespan
Preventing dirt build-up and hotspots helps your whole system last longer.
- 03
Safety and warranty
Many manufacturers recommend professional cleaning to keep your warranty valid. And climbing onto a roof yourself is not without risk.
- 04
Time savings
With the right tools and experience, we get a large installation done quickly. You can spend your time on other things.
- 05
Sustainable approach
Pure water and robotic cleaning keep the use of harmful chemicals to a minimum. Better for the environment and for the panels themselves.
Frequently asked questions about cleaning rooftop solar panels
Can’t find your question? Browse all frequently asked questions or get in touch.
Can I clean the solar panels on my roof myself?
You can, but bear in mind the risk of falling and make sure you use the right cleaning products. A professional clean is safer and usually gives a better result.
Isn’t rain enough to keep the panels clean?
Rain only washes away loose dirt and often leaves limescale or minerals behind. Bird droppings, dust and algae usually stay put, which leads to yield loss.
What does Solarco clean with?
We mainly work with pure water and robotic cleaners. As a result, chemical cleaning products are usually unnecessary, which is better for the panels and the environment.
How much does it cost to have solar panels cleaned?
The price depends on the number of panels, how accessible they are and the size of the installation. We always prepare a tailored quote, so you know exactly where you stand.
Is robotic cleaning suitable for every roof?
Usually, yes. We do always assess the pitch and condition of the rooftop installation first to decide which method suits it best.
