Pigeons and Birds Under Solar Panels: Prevention and Cleaning
Short answer
Pigeons and other birds like the sheltered gap under solar panels, and once they nest there they bring droppings, nesting material and, sometimes, damage to cables. The most reliable prevention is a bird mesh fitted around the edges of the array without drilling into the panels, ideally at installation or as soon as birds start visiting. Droppings on the glass are a separate, simpler problem: regular cleaning with water and a soft brush handles them.
Birds are a common sight on Punjab rooftops, and many homes keep pigeons. This guide explains what birds actually do to a solar system, how to stop them nesting, and how to clean up safely.
Why birds choose the space under panels
The gap between a panel and the roof is shaded, sheltered from wind and rain, and hard for cats and crows to reach. For a pigeon, it is an ideal nesting spot. Low, flush-mounted arrays on sloped or flat roofs, with a small gap at the edge, are the most attractive. Higher elevated structures are more open and usually see less nesting, though birds may still perch on the frames.

What birds do to a solar system
| Problem | What happens | Why it matters |
|---|---|---|
| Droppings on the glass | Blocks light on a few cells | Acts like a small permanent shadow; output drops and hot spots can form |
| Nesting material | Twigs, feathers and debris collect under panels | Traps heat, blocks airflow, adds a fire-load next to cables |
| Pecking or scratching cables | Birds pull at cable ties and loose cables | Damaged insulation can cause earth faults and, in the worst case, arcing |
| Droppings on the structure | Acidic droppings collect on steel and fixings | Adds to corrosion over time, especially where water pools |
| Noise and mess | Constant activity on the roof | Droppings spread to water tanks and the roof surface |
A dropping on the glass may look small, but it blocks the cells underneath. Because cells and panels are wired in series, a covered cell can hold back more than its own share. Our guide to solar panel shading explains why.
Cable damage is the risk to take most seriously. DC cables on the roof carry high voltage whenever there is daylight. Loose cables hanging under panels are easier for birds to reach than cables properly clipped to the structure.
How to stop birds nesting under panels
Bird mesh (the most common fix)
A bird mesh is a strip of coated wire mesh fitted around the outer edge of the array, closing the gap between the panels and the roof. Birds cannot get underneath, but air still flows and rain still drains.
What good mesh fitting looks like:
- No drilling into panel frames. The mesh should be held with clips designed to attach to the panel frame or structure without drilling. Drilling a panel frame can affect the manufacturer's warranty, which; check its terms.
- Corrosion-resistant material. Coated steel mesh lasts better in Punjab's sun and monsoon than plain wire or plastic netting.
- The whole perimeter closed. A single gap is enough for pigeons to get in.
- Clear the area first. Remove nests, droppings and debris before closing the gap, and make sure no birds are trapped inside.
- Access for maintenance. Mesh sections should be removable so technicians can reach cables and connectors.
Other options
- Keep cables tidy. Cables clipped firmly to the structure, off the roof and away from edges, give birds less to pull at. This is part of good installation anyway; see our solar cable guide and MC4 connector and earthing guide.
- Anti-perch spikes on parapets and frame tops can reduce perching, but they do not stop nesting underneath and some birds learn to ignore them.
- Remove food and water sources near the array where you can.
- Keep pigeon lofts away from the array. If your household or a neighbour keeps pigeons, place lofts and feeding areas away from the panels.
What not to do
- Do not use loose plastic netting that birds can get tangled in.
- Do not use sticky gels or chemicals on panels; they can damage the glass coating and frames and harm birds.
- Do not stuff foam or other material under panels; it traps heat and can be a fire-load.
- Do not climb onto panels or lean ladders against them.
When to act
The best time to bird-proof is during installation or soon after, before birds settle. Once nesting starts, the job takes longer because the area has to be cleared first.
Signs that birds are using your array:
- birds flying in and out at the edge of the panels;
- twigs and feathers at the panel edges or in gutters;
- heavy droppings on the roof below the array;
- a drop in output on one string in the monitoring app, with no other explanation.
Cleaning droppings and nests safely
Bird droppings and nests can carry germs, so treat them with care.
- Clean from the roof, not the panels. Never stand on panels.
- Wear gloves and a mask, and avoid breathing dust from dried droppings or feathers.
- Soak droppings on the glass with clean water first, then wipe with a soft brush or sponge. Do not scrape with metal blades.
- Clean early morning or evening, when panels are cool. Cold water on hot glass can stress it.
- Do not pull nests out from around cables. Nests under panels often sit next to DC cables and connectors. Have a technician switch off the system following the inverter manual and clear them.
- Wash your hands afterwards.

How Solar Works Pakistan installs with birds in mind
Our own teams clip cables firmly to the structure, keep connectors off the roof surface and away from sharp edges, and leave the array tidy, which leaves birds less to damage. Structures are designed in-house and carry our 3-year structure warranty. Where nesting is a known problem on a site, our engineers discuss layout and structure height at the survey; see our guide to L2, L3 and elevated structures.
For systems we installed, our 1-year service warranty applies under the applicable project terms, and after the first year service is chargeable. We target sending service personnel within 48 hours of a registered complaint to begin diagnosis. More on our solar installation services.

Frequently asked questions
Why do pigeons nest under solar panels?
The gap under the panels is shaded, sheltered from wind and rain, and hard for predators to reach. Low, flush-mounted arrays with an open edge are the most attractive to them.
Do bird droppings reduce solar output?
Yes. A dropping blocks light on the cells beneath it and acts like a small shadow, which can affect more than its own share because cells are wired in series. Regular cleaning with water and a soft brush removes it.
Is bird mesh safe for my panel warranty?
Mesh fitted with clips that do not drill into the panel frame is the safer approach. Drilling or modifying a panel can affect the manufacturer's warranty, so check its written terms before any fixing.
Can birds damage solar cables?
They can peck or pull at loose cables and cable ties, and nesting material can build up around connectors. Firmly clipped cables and a closed perimeter reduce the risk. Damaged DC cable insulation should be checked by a technician.
Can I remove a pigeon nest from under my panels myself?
Clearing droppings from the glass is fine, but nests under panels usually sit near DC cables and connectors. Have a technician switch the system off and clear them safely.
Does Solar Works fit bird mesh?
