Why Solar Panel Maintenance Matters
Solar panels are designed to be low-maintenance, but occasional cleaning and inspection can help them keep generating well. Dirt, bird droppings, moss and debris can reduce how much electricity your panels produce, and how much depends on your roof and surroundings.
A maintenance visit can include cleaning, electrical checks, mounting inspections and a look at your generation data, so faults are found before they cost you more.
What a Solar Maintenance Visit Can Include
Visual Inspection
- • Check for physical damage or cracks
- • Inspect mounting and roof attachments
- • Examine wiring and connections
- • Look for signs of wear or corrosion
Professional Cleaning
- • Deionised water cleaning (no streaks)
- • Remove dirt, pollen, and bird droppings
- • Clean around panel edges and frames
- • Safe roof access and working practices
Electrical Testing
- • Check inverter performance
- • Test output and voltage levels
- • Verify safety systems functioning
- • Compare to expected generation
Performance Report
- • Detailed maintenance report
- • Photos of panels before/after
- • Performance data and trends
- • Recommendations for improvements
Benefits of Regular Maintenance
Keep Output Up
Removing heavy dirt or shading can help panels generate what they should
Catch Faults
Checks on wiring, fixings and the inverter can find problems early
Protect Investment
Finding problems early can help avoid bigger repair bills later
Maintenance Costs
We don't publish maintenance prices because we have no reliable national figure. Prices vary with system size, roof access (for example whether scaffolding is needed) and location, so get a written price before work starts.
Is It Worth Paying For?
Compare your generation with the same months in previous years. If output hasn't dropped and nothing looks damaged, you may not need a clean yet.
How Often Should You Clean Solar Panels?
Check Your Output (All Homes)
Use your inverter app or generation meter. An unexplained drop compared with the same time last year is the clearest sign something needs attention
More Often If Panels Get Dirty Quickly
Homes near busy roads, farms or trees, or with shallow-angled panels that rain doesn't rinse well, may need cleaning more often
Follow the Manufacturer's Advice
Check your panel and inverter warranty terms for any cleaning or servicing requirements

Common Questions
Can I clean solar panels myself?
Don't climb onto the roof or walk on panels. Working at height is dangerous and panels can be damaged. If you use a cleaning company, ask whether they have public liability insurance and how they access and clean panels.
Does rain clean solar panels?
Rain rinses off some loose dust, but it may not remove bird droppings, moss, lichen or tree sap, especially on shallow-angled panels.
Will dirty panels damage my system?
Everyday dirt mainly reduces output rather than causing damage. Heavy patches, such as bird droppings left for a long time, can shade part of a panel, so it is worth dealing with them.
Is maintenance covered by warranty?
Warranties usually cover defects, not cleaning or routine servicing. Read your panel, inverter and workmanship warranty terms to see whether they require any maintenance, and keep a record of any work done.
