You bought solar to save money. Without proper solar panel cleaning Sunshine Coast residents quietly lose 15–25% of their output within a year — and most never notice.
Why output drops
Coastal dust, salt spray and bird residue form a film that blocks light. Even a thin layer reduces panel efficiency measurably. The system keeps running — it just stops earning what it should.
Hot-spotting damages cells permanently
Bird droppings and uneven shading cause individual cells to overheat. Over time this degrades the panel itself — not just the output for the day.
Why you can't just hose them off
Tap water leaves mineral deposits that block light long-term. Pressure cleaning scratches the panel surface. Both reduce future output.
The right way
Deionised (purified) water, soft-brush method, zero PSI on the panel surface. Spot-free dry, no scratches, full output restored.
An annual solar clean protects the ROI you already paid for. Most owners recover the cost within months of the next bill.
