Solar Panel Cleaning in Stirling –Lichen and Dust Removal

We recently completed a professional clean on a solar system in Stirling, just outside Balclutha.

Despite being only a few years old, the panels had become coated with lichen and dust, affecting their energy output and overall health.

Before the clean

Why Lichen and Dust Are a Serious Problem for Solar Panels

While dust alone can block sunlight and reduce energy production by up to 15%, lichen is even more damaging.

Lichen attaches itself firmly to the panel surface and can cause:

• Permanent staining

• Surface etching if left untreated

• Hot spots that reduce panel efficiency and lifespan

Dust on its own scatters sunlight and decreases output, but when combined with lichen growth, the impact on system performance can be even greater.

Without regular cleaning, panels can suffer long-term damage that affects both their output and their warranties.

The lichen spreads from the frames and moves to the panels

Our Cleaning Process: Deionised Water and Careful Lichen Removal

At Eco Solar Clean, we use pure deionised water and specialized cleaning equipment to safely remove dust, lichen, and grime without damaging your solar panels.

For heavy lichen, we:

• Gently loosen the growth without using harsh chemicals

• Use deionised water for a streak-free, residue-free finish

• Protect the panel’s anti-reflective coating and surface integrity

This ensures a thorough clean while preserving the full efficiency and value of the solar system.

Why Regular Solar Panel Cleaning Matters in Rural Areas

Properties in rural areas like Stirling are especially prone to both lichen and dust accumulation due to:

• Higher moisture levels (encouraging lichen growth)

• Open farmland generating airborne dust

• Limited rain runoff on low-angled panels

Without a regular cleaning schedule, panels in rural environments quickly lose efficiency and risk permanent surface damage.

We recommend cleaning your solar panels every 6 to 12 months to keep them operating at peak performance.
