Why Bird Proof Your Solar Panels?
The sheltered gap under roof-mounted panels is prime nesting territory. Left open, it costs you output, risks damage, and can void warranties.
Lost output
Droppings and nests shade cells and block the airflow panels need to run cool — draining output by as much as 25%.
Fire risk
Dry nesting material packed against wiring and hot componentry is a genuine, well-documented rooftop fire hazard.
Roof & wiring damage
Acidic droppings corrode connectors, cabling and roof sheeting — turning a cheap fix into an expensive repair.
Which birds nest under solar panels?
In Australia, a handful of species cause the vast majority of solar bird problems:
- Pigeons: The most common culprit — they roost and nest year-round in the warm cavity under panels.
- Sparrows: Small enough to squeeze through gaps and build persistent nests between rows.
- Indian mynas: Aggressive nesters that displace native birds and foul the roof cavity fast.
- Starlings: Flock in numbers and pack nesting material tightly against wiring and cells.
The cost of inaction vs the cost of a kit
A professional array clean costs a few hundred dollars — and the birds simply return, so you pay again and again. Meanwhile lost output quietly adds up every year the gap stays open. A one-time mesh barrier from $129 (the galvanised steel kit) or $219 (the 316 stainless steel kit) blocks access permanently, so the problem is solved once rather than managed forever.
Both kits use a thicker 1.3mm gauge steel mesh, with marine-grade 316 stainless available for coastal homes, and every kit ships free with a 10-year warranty.
