Solar Panel Cleaning

Dust, pollen, bird droppings and Western Sydney grime quietly eat into your solar output all year. Professional panel cleaning restores generation, protects your warranty, and pays for itself faster than most people expect.

We clean with purified water and soft brushes only — no detergents or high pressure that could void panel warranties — and we work safely on all roof types.

Ask about combining panel cleaning with gutter cleaning: we're already on the roof, so the bundle price makes sense.

  • Purified water and soft-brush cleaning

Common questions

How much output do dirty panels lose?

Studies and installer data commonly show 10–25% losses on panels that haven't been cleaned in a year or more, especially at lower tilt angles.
