Solar Panel Cleaning Melbourne

Dirty solar panels can lose up to 25% of their energy output. Dust, pollen, bird droppings, lichen, and general grime build up gradually, blocking sunlight from reaching the photovoltaic cells. At Spot On Maintenance, we use purified, deionised water and soft brushes to safely clean your solar panels without scratching the surface or leaving mineral deposits that tap water causes.

Our solar panel cleaning service is more than just a wash. While we're on the roof, we visually inspect each panel for micro-cracks, hot spots, loose clamps, deteriorating seals, and bird nesting underneath the array. Bird nesting is a growing problem in Melbourne. Nesting materials create fire risks and accelerate panel degradation. We offer bird proofing mesh installation to prevent birds from nesting under your panels permanently.

We clean panels on all roof types including tile, metal, flat, and steep pitch. Our crews are trained in working at heights and use appropriate safety equipment on every job. For maximum energy recovery, we recommend cleaning every 6-12 months depending on your location. Properties near trees, busy roads, or the coast accumulate grime faster. Many customers combine solar panel cleaning with gutter cleaning and roof washing for a complete roof maintenance package.
