Ascent Exteriors clean domestic solar panels across Saffron Walden and the surrounding Uttlesford & NW Essex villages, from £4 a panel. We don't sell or install panels — we clean them, using purified water and soft brushes (no chemicals) to restore the output that dirt, pollen and bird mess steal. Fully insured and locally based.

Dirty solar panels can lose up to 25% of their efficiency. Bird droppings, pollen, dust, and general grime build up over time and block sunlight from reaching the cells.
Our specialist clean restores your panels' performance so you get the most from your investment. We use purified water and soft cleaning tools — no chemicals, no risk of damage.
Why clean your solar panels?
Solar panels only earn their keep when light actually reaches the cells. Studies put the loss from a dirty array at 15–25% — and in our part of Essex the culprits are specific: tree pollen in spring, dust off the surrounding farmland in summer, and bird mess from the mature trees that line so many local gardens. A panel that looks "fine" from the ground is often quietly costing you generation. A clean typically pays for itself in recovered output.
We clean panels — we don't install them
Worth being clear: Ascent Exteriors is an exterior cleaning company, not a solar installer. We don't sell, fit or repair panels. If yours are underperforming, a professional clean is the cheapest first thing to try before you call an installer — and it's exactly what we do, across Saffron Walden and the nearby villages.
How we clean them — safely
We use a purified-water pole system and soft brushes, reaching most installations from the ground so there's no ladder leaning on your roof or panels. Purified water dries spot-free with no detergent residue — important, because household cleaners and abrasive pads can smear panels or damage the anti-reflective coating (and even affect some warranties). We work gently, check for any obvious shading or debris while we're there, and tell you honestly if a panel looks faulty rather than just dirty.
How often should panels be cleaned?
Once or twice a year suits most homes. If your array is under or near trees, backs onto farmland, or sits at a low pitch (where rain runs off too gently to self-clean), lean towards twice a year — spring and late summer. We'll give you an honest view for your roof rather than booking visits you don't need.
