Professional Solar Panel Cleaning in Coffs Harbour

We recommend solar panel cleaning at least once per year — and every 6 months for properties near the ocean or under trees. The Coffs Coast’s salt spray, high humidity, and bird activity create a triple threat that rain alone cannot address. Professional cleaning can restore up to 25–30% lost efficiency, which translates directly to savings on your electricity bill.

Improper cleaning can void your warranty — which is why professional cleaning matters. Pressure washers, abrasive tools, and harsh chemicals can scratch the glass surface and anti-reflective coating. Laing Pressure Washing uses warranty-safe methods only: purified water, soft brushes, and gentle low-pressure rinsing that comply with all major manufacturer guidelines. In fact, many manufacturers require panels to be kept reasonably clean as part of their warranty conditions.

Dirty solar panels can lose between 15–30% of their energy output depending on the type and severity of buildup. On the Coffs Coast, the most common efficiency killers are salt film, bird droppings (which can cause hot spots reducing output by up to 33% even from a few droppings), and mould growth. For a typical 6.6kW residential system, a 25% efficiency loss means approximately 1.65kW less generation — a professional clean typically pays for itself within weeks.

Yes — from residential rooftop systems to commercial and community solar arrays across the Coffs Coast. The warranty-safe method is the same either way (purified water, soft brushes, low-pressure rinsing), but commercial arrays are scheduled around your operations, carried out to site safety requirements, and invoiced to the business or managing agent directly. On larger arrays where lost output is measurable, a scheduled maintenance clean typically pays for itself in restored generation. Fully insured — call 0492 914 209 for a free quote.
