Your Solar Panels Only Make Electricity When Sunlight Can Reach Them.
Here in the UK, we usually get enough rain to keep most solar panels fairly clean. For many homes, the weather does a lot of the work. Some panels need a little extra help.
Dust, pollen, bird mess, moss and lichen can build up in ways rain alone won’t shift, and all of it gets in the way of the daylight your panels need. Less light in means less electricity out.

In the UK, rainfall usually does most of the work for you, washing away everyday dust and pollen on standard-pitched roofs. That said, an annual solar panel cleaning is worth it if you’re near a busy road, farmland, or an industrial site, under trees where sap and droppings build up, or have a low-pitch or flat roof where rain doesn’t run off as effectively.
If any of these apply to you, a clean every couple of years helps maximise your savings by keeping your panels generating at their full potential rather than losing output to a build-up you can’t always see.
For rooftop solar panels which cannot be seen close up, the easiest sign is a drop in your system’s output. If your monitoring app or inverter shows lower generation than the same month last year, even in similar weather, dirt could be the cause.
From the ground you might see a dull film across the glass, bird droppings, moss or lichen around the edges, or leaves and debris gathering at the bottom of the panels. Panels near trees, farmland, busy roads or the coast tend to get dirty faster. If you’re not sure, get in touch and we’ll take a look.
Yes. Just let us know before your visit and we’ll add it to your quote. Doing both at once means one visit and less disruption, and it stops birds nesting under your panels, where they can damage cables and leave mess that builds up quickly.
TrueCare clean solar panels for homes and businesses across England. Wherever you’re based, we can get a team to you. Contact us for a quote and we’ll arrange a time that suits you.
We advise against it as it’s not always straightforward — panels are often on a pitched roof, and the wrong technique or equipment can leave streaks, scratches, or even void your warranty. There’s also a potential risk of electric shock.
Harsh chemicals, abrasive cleaners, and high-pressure jets should all be avoided, as they can damage the glass and its protective coating.
A professional solar panel cleaning service ensures the job is done safely and without any risk to your panels.

No — solar panels aren’t designed to take the weight of a person and can crack or break underfoot. Their surface can also be slippery, which is especially risky when working at height, so it’s best left to a professional solar panel cleaning service with the right access equipment.
The cost of solar panel cleaning depends on the size of your system/how many panels you have. Get in touch for a quote based on your specific setup.
Most commercial and ground-mount arrays benefit from a clean once or twice a year. Sites near farmland, quarries, busy roads, industrial areas or the coast may need more frequent cleaning, because dust, pollen, salt and bird activity build up faster.
Ground-mount arrays can also be affected by vegetation and soil splashback. On larger systems, a small drop in efficiency adds up to a significant loss in generation.
We can set up a regular cleaning schedule for your site, work around your operations, and provide a report after each visit.
Yes — if diagnostics identifies a fault, our engineers can carry out the repair for you. And if your system is still under warranty, we’ll handle liaising with the manufacturer to get parts replaced or repaired on your behalf.
