Whether your panels are roof-mounted or ground-level, find checked solar panel cleaning services in Argyll And Bute with Checkatrade to keep them in top working order.

Dirty solar panels can lose performance, especially if you live in a dusty, coastal, or polluted environment. Regular cleaning helps to maintain their efficiency and protect your investment.

What is solar panel cleaning — and why it matters

Solar panel cleaning involves removing dust, grime, bird droppings, pollen, and other debris that block sunlight from reaching the photovoltaic cells.

Over time, ‘soiling’ (dust and particulate accumulation) can reduce a panel’s output by a significant amount. That is, they’ll become less efficient and you’ll notice a drop in performance.

Cleaning your solar panels helps to restore performance, extend their lifespan — and may even be required under some manufacturer warranties.

How do you clean solar panels?

A checked solar panel cleaner will typically:

• Inspect the array and note any damage or hotspots
• Safely shut down the system
• Access panels (often using extension poles or lifts, especially for roof-mounted arrays)
• Clean panels using soft brushes, water-fed poles, and non-abrasive, biodegradable cleaning fluids
• Rinse, dry, and restart the system, testing for proper operation

The method must avoid damaging the glass, seals, or electrical components.

How much does solar panel cleaning cost?

The cost of solar panel cleaning will vary based on the number of panels, height and pitch of the roof, difficulty of access, condition of the panels, and travel/time.

However, as a guide, solar panel cleaning typically costs around:

• £15 per panel
• £60–£100 to clean ~40 panels at ground level
• £150–£300 to clean ~40 panels if above one storey

Aim to get a selection of quotes from solar panel cleaners who cover your area. That way, you can be sure of getting a fair and competitive price.

How often should you clean solar panels?

The frequency of cleaning largely depends on the conditions where you live and where your panels are located.

• Most installers suggest cleaning your solar panels 1–2 times per year, especially in dusty, coastal, or polluted environments
• If your panels are on the roof and you get plenty of rain, cleaning every 12–18 months might be sufficient
• In some cases, if your panels are on the ground, are heavily soiled, or show visible drops in performance, they may require more frequent cleaning

DIY vs professional cleaning

You can clean your own solar panels if they’re easily accessible and safe to reach — but it’s risky on rooftops and may void warranties.

A checked solar panel cleaner will bring safety equipment and the correct tools and experience to avoid damage and ensure full coverage. They also often comply with warranty conditions.
