Domestic Solar Panel Cleaning

Specialist Solar Panel Cleaning for Homes Across Bristol & London

Protect Your Panels, Boost Your Output

Dirt, bird droppings, moss and dust can accumulate on your solar panels over time, blocking out the sun’s rays and decreasing your panels’ effectiveness. DW Windows & Gutters Ltd is proud to provide safe and efficient solar panel cleaning for homeowners using only pure water and soft bristle brushes to ensure your system’s longevity.

Frequently Asked Questions

Why should I get my solar panels cleaned?

Dust, debris, and bird droppings block sunlight and reduce energy output. Cleaning helps improve efficiency and extend the life of your system.

How often should domestic panels be cleaned?

Once a year is ideal for most homes. If you’re in a dusty, coastal, or high-pollen area, a 6-month schedule might be better.

Do I need to turn off the panels before cleaning?

We recommend it for safety. If you’re unsure how to do this, we’ll advise before the visit or guide you on the day.

Is it safe for my roof and panels?

Yes! We use soft brushes and deionised water, no chemicals, ladders, or pressure washing, so your panels and roof remain undamaged.

Where do we cover?

DW Windows has a large operational area, and are very proud to cover such a large geographical location. In particular we have a large footprint in both Bristol and London, both of which are key locations for us. We have a long history of happy customers and proven track record in both cities. We offer the same high-quality workmanship, dependable service, and specialist installation knowledge to every customer.

In Bristol, our coverage includes not just the city centre, but also many outlying areas like Clifton, Redland, Stoke Bishop, Downend, Westbury-on-Trym, Filton, Bradley Stoke, and beyond into North Somerset, South Gloucestershire and more. So, whether you live in a flat or house in a modern development in the suburbs, or an old Victorian terrace in one of Bristol’s historic neighbourhoods, we’ve got you covered for residential and commercial projects.

In London, we work throughout the capital, including many boroughs like Camden, Hackney, Islington, Hammersmith, Richmond, and more. We also travel to Outer London areas including Croydon, Ealing, Bromley, Kingston, and others. So, whether it’s a luxury refit in Central London, or energy efficient replacements in a suburban semi in Greater London, our team is on hand to take care of the job with the same dedication and attention to detail.

In fact, we don’t just cover the larger cities of Bristol and London. We also serve a number of outlying towns, villages and rural areas. So if you live just outside one of these cities in the Home Counties, the South West or the Severn Valley region, there’s a good chance we can cover your area. Our team travels well beyond the city limits on a regular basis to service our customers.

If you can’t see your location mentioned above, don’t panic, please get in touch! We are always more than happy to discuss your project and confirm whether or not we can help in your location. At DW Windows, we love what we do, and we love providing a top-quality service – so if you’re anywhere near Bristol, London or even just a bit outside of these locations, it’s always worth giving us a call to find out!
