Solar panel cleaning across Townsville.

The method — deionised water + soft-brush, no pressure.

We use a telescopic carbon-fibre pole fitted with a soft natural-bristle brush head, fed by deionised water from a roof-mount DI cartridge tank. Deionised water is essential because tap water leaves mineral spotting as it dries on the panel surface; DI water dries clean. Soft bristles physically lift bonded dust and dropping spots without scratching the anti-reflective coating. We never use pressure-washers, stiff bristles, abrasive pads, or detergents — all of which void Tier-1 manufacturer warranties.

What we remove.

• Red dust — inland-blown August-November westerly load, often mixed with monsoon-rain residue into hard mineral streaks.
• Bird droppings — ibis, corella and seabird acid spots, hard-baked under the dry-tropics sun. The single biggest output killer in the eastern suburbs.
• Lichen and algal growth — usually accumulates around panel-edge silicone seals where moisture pools after monsoon.
• Salt-air film — bonded mineral coating on coastal-facing arrays (North Ward, Pallarenda, South Townsville foreshore).
• Organic debris — mango leaf, jacaranda flower, palm-frond fragments in the inner-city suburbs with mature street trees.

Cleaning frequency for Townsville.

Annual minimum across all of Townsville. Some properties need more:

• Semi-annual (6-monthly) for coastal-fringe properties exposed to salt-spray — North Ward, Pallarenda, South Townsville foreshore, Bushland Beach.
• Semi-annual for properties immediately under high-traffic ibis or corella flight paths — Strand foreshore, Ross River corridor, Annandale Lakes precinct.
• After-event clean following a major dust storm or extended bushfire smoke event.
• Pre-sale clean for any solar-equipped Townsville home going to market — immediate ROI in presentation and avoided buyer-side price negotiation.

Expected output restoration.

We measure inverter output before the clean and again after, using the inverter’s own display or telemetry app. Typical restoration for a Townsville array that hasn’t been cleaned in 12+ months is 15-25% of nameplate output. Coastal or ibis-zone arrays neglected for 2-3 years can recover 30%+. We provide a written before/after report with each clean — dated, photographed, suitable for your Tier-1 warranty file.
