Key points
- The sheltered, warm gap under rooftop panels is ideal for pigeons, and in Melbourne also common mynas and starlings.
- Clip-on PVC-coated wire mesh around the edge of the array is the most reliable fix. Spikes, decoys and gels rarely work long term.
- Typical 2026 cost for a standard single-storey home is about $350–$700 (around $18–$30 per metre of perimeter). Two-storey roofs, large arrays and nest clean-outs cost more.
- Mesh should clip on without drilling panel frames. Native birds are protected, so check before removing an active nest.
Bird proofing solar panels means sealing the gap between your panels and the roof so birds can’t get underneath to nest. The usual method is a clip-on wire mesh skirt fitted around the edge of the array. It doesn’t touch the glass or require drilling. If you can hear cooing or scratching on the roof, or see nesting material poking out from under your panels, it’s worth acting early. Nests grow every season, and the clean-up gets bigger and more expensive.
Why do birds nest under solar panels?
From a bird’s point of view, the space under a solar array is close to perfect. It’s dry, shaded in summer, warm in winter, high off the ground and protected from predators. Pigeons (feral rock doves) are the main culprits in both Adelaide and Melbourne because they nest year-round and return to the same spot. Common mynas, starlings and sparrows also use the gap.
Low-pitched roofs and arrays with a large gap at the lower edge are most at risk. So are homes near shopping centres, train lines, silos or anywhere birds already roost. This guide is part of our solar maintenance and repairs guide.
Signs birds are nesting under your panels
- cooing, scratching or fluttering on the roof, especially early morning
- twigs, straw or feathers sticking out from under the panels or collecting in gutters
- a build-up of droppings on the panels, roof, gutters, paths or cars below
- birds flying in and out from under the array
- blocked gutters or downpipes, or a musty smell
- a gradual drop in solar output, which you may spot in your solar monitoring app.
What damage can nesting birds cause?
A few birds are a nuisance. An established colony can cause real problems:
- Lost output. Droppings on the glass shade cells. Because cells are wired in series, a few marks can reduce a whole panel’s output.
- Debris around electrical parts. Dry nesting material packs around cables, connectors and any rooftop isolators. It traps moisture and is not something you want near electrical equipment.
- Roof and gutter damage. Acidic droppings and wet nest material can stain and corrode roofing, and blocked gutters can overflow into eaves.
- Pests and hygiene. Nests attract mites, lice and rodents. Rodents can chew cable insulation.
- Harder servicing. Electricians can’t properly inspect wiring buried under nests.
If you notice burning smells, scorch marks or a fault message on your inverter, treat it as an electrical issue first. Follow our checklist for when your solar is not working and call a licensed electrician.
Bird proofing solar panels: options compared
| Method | How it works | Effectiveness |
|---|---|---|
| Clip-on wire mesh (PVC-coated or stainless) | Mesh skirt clipped to the panel frames and shaped to the roof, closing the gap | High. The industry standard; removable for servicing |
| Rigid guards or “solar skirts” | Solid or perforated strips along the array edge | Good on some roof types; less flexible on uneven tiles |
| Spikes | Stop birds landing on edges and ridges | Low on their own; birds still get underneath |
| Decoys, gels, reflectors, ultrasonic devices | Try to scare birds away | Low; birds usually get used to them |
| Netting over the whole array | Covers the panels | Not recommended; shades panels and traps debris |
Mesh is the method most solar and pest professionals recommend because it’s a physical barrier, not a deterrent. Good systems use UV-stabilised, coated mesh and purpose-made clips that hook onto the panel frame. Ask what the mesh and clips are made of and how long they’re warranted.
How much does bird proofing solar panels cost in 2026?
As of 2026, Australian installer price guides put professional mesh at about $350–$700 for a standard home, or roughly $18–$30 per metre of array perimeter. These are market ranges, not Solar Beat prices.
Worked example: a 6.6–7kW system with 16 panels in two rows of eight (portrait) is roughly 9.1 metres wide and 3.5 metres high. That’s a perimeter of about 25 metres. At $18–$30 per metre, the mesh works out to roughly $450–$760.
Things that push the price up:
- Existing nests and droppings that need removing and cleaning first
- Two-storey or steep roofs that need extra safety equipment
- Several separate arrays (more edges and corners to seal)
- Tiled roofs with uneven profiles that take longer to fit
- combining the job with a panel clean or electrical inspection (more work, but often cheaper than separate visits).
The cheapest time to fit mesh is when your system goes in, while the installer is already on the roof. If you’re planning a new system, ask for it in your quote. Our guide to the solar installation process explains what to ask for before installation day.
How professional bird proofing is done
- Inspection. Check the array, the extent of nesting and whether any birds or eggs are present.
- Nest and droppings removal. Material is cleared from under the panels and gutters, wearing protective gear.
- Cleaning. The roof under the array and the panel glass are cleaned without directing high-pressure water at panel seals, junction boxes or connectors.
- Electrical check. Ideally a licensed electrician inspects cables, connectors and any rooftop isolators exposed by the clean-out.
- Mesh fitting. Mesh is cut to size, clipped to the panel frames, shaped to the roof and joined at corners so there are no gaps.
Afterwards, rain should keep the panels reasonably clean. Our guide to solar panel cleaning covers when an extra clean is worth it.
Will bird mesh void my panel warranty?
It shouldn’t if it’s fitted properly. Quality mesh systems use clips that hook onto the panel frame without drilling, adhesive or contact with the glass. Drilling into frames or fixing anything to the glass can breach panel warranty conditions. If you’re unsure, ask the installer to confirm the clip type is compatible with your panel brand, and keep the invoice with your warranty paperwork.
Native birds and the law
Native birds are protected under state wildlife laws in both South Australia and Victoria. That matters because some natives, such as the noisy miner, look similar to the introduced common myna. If a native bird has an active nest with eggs or chicks, don’t remove it. Wait until the young have left, or seek advice from your state environment department. Feral pigeons, common mynas and starlings are introduced species. Even so, any removal should be humane, and no birds should be sealed inside the mesh.
In South Australia, PIRSA treats the common myna as a pest that isn’t yet established in the state and asks people to report sightings to its Pest Alert Hotline (1800 084 881). If you think mynas are nesting under your panels in SA, report it. In Melbourne, mynas are widespread, so mesh is often the practical answer. For local context, see our guides to solar in Adelaide and solar in Melbourne.
Frequently asked questions
Can I bird-proof my solar panels myself?
DIY mesh kits exist, but the job means working on the roof around live electrical equipment, which carries real fall and shock risks. Nest removal can also expose damaged cables that need an electrician. For most homes it’s safer to use a professional, ideally one who works with a licensed electrician.
Does bird mesh affect solar panel performance?
No. The mesh sits around the edge of the array, below the panels, and doesn’t shade the glass. It can actually help output by keeping droppings off the panels. Good mesh still lets air flow under the panels, which helps keep them cool.
How long does solar panel bird mesh last?
Quality UV-stabilised, coated mesh with purpose-made clips is designed to last many years. It can be unclipped and refitted when panels are serviced or replaced. Ask your installer what the mesh and clips are made of and what workmanship warranty applies, and have the mesh checked during your regular solar service.
Is it too late to bird-proof if pigeons are already nesting?
No, but the nests must be cleared first. A professional will remove nests and droppings, clean underneath the array and then fit the mesh so no birds are trapped inside. If a native species has an active nest with eggs or chicks, wait until the young have left or seek advice from your state environment department.
If birds have been nesting under your panels, our Adelaide and Melbourne team can inspect your system and any wiring exposed by nesting as part of a solar service. Planning a new home solar system? Ask about bird mesh in your quote. Contact us to book an inspection.
