Pigeons Under Solar Panels: The Damage They Cause & How to Stop It
Pigeons love nesting under solar panels. The gap between the panels and your roof is warm, shaded, sheltered from wind and rain, and safe from predators — essentially a purpose-built pigeon penthouse. Unfortunately, what's great for pigeons is bad news for your panels, your roof and your health. Here's what actually happens, and how to stop it for good.
Why pigeons nest under solar panels
Rooftop solar creates a protected cavity that pigeons (and sparrows, mynas and starlings) treat as prime real estate. Once a pair moves in and breeds, others follow, and a small problem becomes a colony surprisingly fast.
The damage birds cause
- Droppings and health risks: Pigeon guano is acidic and carries bacteria, fungi and parasites. It builds up on your roof and in your gutters and can pose a genuine health hazard.
- Lost solar output: Droppings and nesting debris shade cells and block the airflow that keeps panels cool, quietly dragging down the output you paid for.
- Fire and wiring risk: Nesting material is dry and flammable, and birds nesting around cabling can damage wiring — both real safety concerns on a live electrical system.
- Roof and gutter damage: Nests block gutters and downpipes, and acidic droppings degrade roofing over time.
- Noise and mess: Cooing, scratching and constant droppings down your walls and windows.
How to stop birds nesting under solar panels
The proven, humane fix is mesh bird proofing: a steel mesh clipped around the perimeter of your array that seals the gap so birds simply can't get underneath — without harming them and without drilling into your roof or panels.
Spikes and gels are messy and unreliable around solar; a proper mesh barrier is what professionals use. Our DIY solar bird proofing kits use the same 1.3mm steel mesh and non-penetrative clips the pros use, and most homeowners fit them in 2–3 hours. Choose galvanised for inland homes or 316 stainless for the coast.
Do it once, done for good
Bird proofing is a one-time job that protects your panels, your roof and your investment for years. If birds have already moved in, clear the debris and fit mesh to keep them out for good. Read the installation guide →
