Solar Panel Cleaning
Dirty solar panels lose up to 20% of their output. Our specialist purified-water cleaning service restores peak efficiency, protects your warranty and is carried out by trained technicians who understand PV systems.
Professional Solar Panel Cleaning in North Somerset
Solar panels attract bird droppings, pollen, dust and atmospheric grime that gradually builds up and reduces energy output. Studies show dirty panels can lose 15–20% of their efficiency — potentially adding up to hundreds of pounds in lost generation over a year. Top Glass uses the same professional purified-water systems we use for window cleaning to safely clean solar panels without chemicals or abrasives, restoring performance and protecting the panel surface coating.

Your Solar Panel Cleaning in 4 simple steps
Output check
We review your inverter output data before cleaning so we can compare performance before and after the clean.
Panel inspection
We check each panel for any cracks, damage or bird strike before cleaning begins, noting any issues in our report.
Purified water clean
Panels are cleaned with deionised, purified water and soft brushes — no chemicals, no residue and no risk to panel coatings.
Post-clean report
We document the clean and share before/after photos. We'll also advise on any panels showing signs of damage or shading issues.
What Affects the Price?
Every property is different. These are the main factors we consider when putting together your quote.
Number of panels
We price by the number of panels in the array. A typical domestic installation of 8–12 panels costs less than a larger array of 16 or more.
Roof pitch & access
Panels on a steep roof pitch or with difficult access take longer to clean safely, which is reflected in the quote.
Bird fouling
Panels with heavy bird droppings require additional attention and time compared with panels with light dust or pollen accumulation.
Cleaning schedule
Customers who book annual or biannual scheduled cleans receive preferential pricing compared with one-off reactive bookings.
