The gap between your solar panels and the roof is prime nesting real estate for pigeons, starlings and cockatoos. Left unaddressed, it causes shading, cable damage, gutter blockages and a mess of droppings down the wall. Bird proofing mesh closes the gap.
What bird proofing mesh does
A perimeter clip system holds a stainless steel or powder-coated mesh around the entire edge of the solar array. Birds can't get in; airflow underneath is unaffected.
- Blocks pigeons, starlings and cockatoos entering the under-panel space
- Stops nesting material clogging gutters and downpipes
- Protects solar cables and micro-inverters from rodent and bird damage
- Preserves warranty on most solar systems (unlike DIY netting)
Why it matters for solar performance
Bird droppings on cells reduce panel output. Nesting material shades sections of the panel and causes hot spots. Over years, both accelerate cell degradation.
DIY vs professional
DIY plastic netting under solar panels typically lasts a season, sags into panels, and can void solar warranties. A properly installed clip-based mesh system lasts the life of the array.
Key takeaways
- Bird proofing mesh clips around the panel perimeter — no drilling into panels
- Protects panel output, cable insulation and gutters below
- DIY netting usually fails within a season
