Solar panels sit outside in all weather, which means they pick up dirt, dust, pollen and bird fouling over months and years — and unlike a window, most people never get up close enough to notice how grimy they've become. Our solar panel cleaning service in Hull and East Yorkshire clears that build-up safely, using the right equipment for the roof.
What's included
- Assessment of panel layout, roof pitch and access before we start
- Removal of dirt, dust, pollen and bird fouling from every panel
- Cleaning with soft brushes and purified, deionised water — no harsh chemicals
- Ladderless, pole-fed cleaning wherever access allows
- Rinse and finish to a streak-free result
- Final visual check once cleaning is complete
Why solar panels get dirty
Dust and airborne grime settle on panels gradually, but the bigger culprits are usually pollen in spring and bird fouling year-round, especially on panels near trees or overhead wires. On low-pitched or shaded panels, algae and moss can also take hold at the edges. None of it is usually visible from ground level, which is why panels often go years without a clean.
Why it's worth cleaning them
A layer of grime or bird mess sitting on a cell can partially shade it, and a shaded cell doesn't generate as well as a clean one. Keeping panels clean can help maintain performance over time — we're careful not to overstate this, as the actual effect depends on your system and how dirty the panels were to begin with. Think of it as routine maintenance rather than a guaranteed energy saving.
How we clean safely
We use soft, non-abrasive brushes with purified deionised water, which dries without leaving mineral deposits or streaks — no detergents or chemicals needed. For most bungalows and standard houses we use a ladderless, pole-fed system that reaches the panels safely from the ground or a stable platform. Steeper roofs or unusually positioned arrays are assessed individually, and we'll always confirm the right approach before booking.
Domestic and commercial systems
We clean domestic arrays on houses and bungalows across Hull and East Yorkshire, and can also quote for small commercial installations — get in touch with details of the site and we'll let you know what's involved.
Our process
- 1. Assess — we check the panel layout, roof pitch and access before quoting
- 2. Prepare — we set up the pole-fed pure water system or appropriate equipment for the roof
- 3. Clean — each panel is soft-brushed and rinsed to lift dirt, dust and bird fouling
- 4. Inspect — a final check confirms an even, streak-free finish
How much does solar panel cleaning cost?
Solar Panel Cleaning from £60, which covers a standard domestic array of up to 10 panels. Larger arrays are £4 per panel after that, and we'll always confirm an exact price before starting work.
What affects the price:
- Number of panels in the array
- Roof pitch and how easy the panels are to reach
- How long it's been since the last clean
- Whether it's a one-off clean or a regular maintenance visit
