Solar panel cleaning prices, per panel.
Solar panel cleaning priced the way the trade prices it: a rate per panel set by access, floored by a firm minimum charge — sold on protecting the asset, not just a wash.
How it prices: A rate per panel (£5–£12, around £8 typical) times the panel count, floored by a minimum charge of £60–£65 that is never broken. Access and soiling set where in the band you sit. Bird-proofing — pigeon mesh around the array — is the high-ticket upsell at £300–£600+, shown here as an indicative £450 and quoted for real after seeing the roof. Treat the output as a starting band, not gospel — gather 15–30 local price points before you commit to a number.
What solar panel cleaning costs in the UK in 2026
Solar panel cleaning is priced per panel — typically £5–£12 a panel, around £8 as a starting point — with a minimum charge of about £60–£65 that every domestic job is floored at. A standard 12-panel home array is around £90–£95; a larger, mossy or awkward roof pushes toward the top of the band.
The pitch is return on investment: a dirty array can lose real generation, so a £90 clean protects a £6,000–£7,000 asset — not just "a wash".
If you're the one with the pure-water pole
Panels book on an annual or twice-a-year cycle, so a £90 clean becomes a customer worth several hundred pounds over a few years. The high-ticket add-on is bird-proofing — pigeon mesh around the array at £300–£600+, quoted separately — plus gutters, windows and fascias while the pole is out.
The full method — per-panel pricing, the minimum charge, bird-proofing, annual plans, commercial arrays — is in The Solar Panel Cleaning Works, £47.
Pricing questions, answered plainly
How much does solar panel cleaning cost in the UK?
Around £5–£12 per panel (about £8 typical), with a minimum charge of £60–£65. A standard 12-panel home array is roughly £90.
Is there a minimum charge for solar panel cleaning?
Yes — £60–£65 is standard and never broken. If the per-panel maths comes to less on a small array, the minimum is what's charged.
How often should solar panels be cleaned?
Once or twice a year in most of the UK — dirt, moss and bird mess reduce output, so an annual clean protects the generation the panels were installed for.
What is bird-proofing for solar panels?
Pigeon mesh fitted around the array to stop birds nesting underneath — a separate one-off job at £300–£600+, quoted after seeing the roof, not folded into the clean price.
