Professional Solar Panel Cleaning in Cornwall

Solar panels are a long-term investment in both your property and the environment — but like any exterior surface, they’re constantly exposed to the elements. In coastal regions like Newquay and across Cornwall, algae, lichen, moss, and grime can accumulate quickly, especially on panels that haven’t been cleaned in years.

At Atlantic Clean, we specialize in non-abrasive, biocide-based solar panel cleaning that’s specifically designed to remove organic build-up without damaging the delicate surface of your panels.

Why Solar Panel Cleaning Matters

Dirty panels don’t just look bad — they reduce energy output. Studies have shown that even light soiling can cut efficiency by up to 20%, and in cases of thick algae or lichen buildup, the losses can be much higher. For panels to function properly, every cell needs clear, unobstructed access to sunlight.

In one recent project, we removed years of baked-on algae using a solar-safe biocide treatment. This advanced formula breaks down biological growth at the root level and continues working over time — keeping the panels clean long after the initial application.

Our Process: Safe, Thorough, Long-Lasting

We never use pressure washers or abrasive tools. Instead, our solar panel cleaning system follows best-practice guidelines from panel manufacturers and industry standards:

• Inspection & Rinse: We start by assessing panel condition and rinsing loose debris.

• Biocide Application: A specialist solar-safe biocide is applied across all affected areas. This targets algae, moss, lichen, and bacteria at the source.

• No Scrubbing Needed: The treatment penetrates and breaks down growth gently, avoiding any risk of scratching or damaging the anti-reflective coating.

• Self-Cleaning Action: The panels continue to self-clean with rainfall in the months following treatment, helping maintain performance.

The Result? Cleaner Panels, Higher Output

After our treatment, panels regain their original clarity — and their efficiency. Homeowners immediately see a boost in energy generation, along with the peace of mind that comes from knowing their system is protected and performing.
