Pigeons Under Solar Panels: How to Keep Birds and Pests Out (and What It Costs)

Pigeons under solar panels are a common problem because the gap between the panels and the roof is a dry, shaded, predator-free spot to nest. The usual fix is to clean out the nests and debris, then close off the edges of the array with a wire mesh guard that clips to the panel frames without drilling. Doing it early matters, because nests trap debris and squirrels or rodents that follow can chew wiring.

Key takeaways

• The gap under rooftop panels attracts pigeons, sparrows and squirrels. Federal research on solar upkeep lists bird nests and animals reaching wiring as known maintenance issues.
• The standard fix is a mesh barrier around the edge of the array. Many products clip on with no drilling.
• Never drill into panel frames. At least one major panel maker's manual says not to drill extra holes, and calls unauthorized changes misuse that voids the limited warranty.
• Equipment warranties usually do not cover animal damage or the labor to fix it. Check your installer's workmanship warranty and your home insurance.
• Rock pigeons are not protected by the federal Migratory Bird Treaty Act, but many other birds are. Check what is nesting before you remove anything.

Why pigeons and other pests end up under solar panels

A rooftop array leaves a gap of a few inches between the panels and the shingles. To a pigeon, that gap is ideal. It is out of the rain and wind, hidden from hawks, and often warm.

The U.S. Department of Energy's Federal Energy Management Program (FEMP) tells solar owners to watch for debris buildup and remove animal nests as part of routine care. The national lab's O&M best practices guide (written by the lab formerly called NREL, now the National Laboratory of the Rockies, or NLR) says birds add soiling, plus "nests that need to be removed and seeds that can sprout on arrays." It also says squirrels and similar animals need to be kept away from wiring.

The usual suspects:

• Pigeons and sparrows nest and roost under the panels and leave droppings on the roof and gutters.
• Squirrels carry nesting material in and may chew on cables.
• Rats and mice can get in where the array is close to trees or the roof edge.

Warning signs of birds or pests under your panels

You rarely see the nest itself. You see what it causes. Walk around the house with binoculars once a season and look for these signs:

• Birds flying in and out from the edge of the array, especially in spring.
• Twigs, feathers or nesting material poking out from under the panels.
• Droppings building up on the roof below the array, on the gutters or on the panel glass.
• Cooing, scratching or scurrying sounds in the attic or near the roof.
• A drop in production in your monitoring app, or one panel or microinverter showing much less output than the rest.
• An inverter error about a ground fault or insulation problem, which can mean a damaged cable.

The national lab's guide notes that where bird populations are large, soiling losses can build up "as high as 0.5%/day." Uneven dirt can also lead to "localized hot-spot failures" on panels. A single smudge is no reason to panic, but a steady buildup is worth fixing.

How to keep pigeons out from under solar panels

The fix that lasts is a physical barrier. Spikes, fake owls and sound devices do not close the gap, so birds can still get in. A mesh skirt around the edge of the array blocks the way in.

Step 1: Clear out what is already there

A pro removes nests, droppings and debris from under the panels and the gutters first. If you seal the array with nests still inside, you trap the problem in and may trap birds too.

Step 2: Install mesh around the array edge

The mesh runs along every exposed edge of the array, from the panel frame down to the roof. Products differ in how they attach:

• Bird-X says its solar mesh kit uses stainless steel mesh and UV-protected nylon clips that fasten "without the need for drilling holes or using glue."
• Nixalite says its clips "slip over the lip of the solar panel framework" with no drilling, and its directions call for a clip every 18 inches or less.
• Racking maker Unirac sells a tool-free guard called GUARDIAN with metal clips that engage the panel's return flange. Unirac lists it for panels that have a return flange, so check your panel model.

Step 3: Leave the mesh as-is during upkeep

Mesh should stay off the panel glass and leave room for airflow. Any time a technician removes panels for roof work, ask them to put the guard back.

Bird proofing and warranties: what to protect

This is where a cheap job can get expensive. Read your panel manual before anyone fastens anything to the array.

Qcells' North American installation manual (revision 09, valid from March 2025) says: "do not modify the module (e.g. do not drill any additional holes)." The manual also says misuse, including unauthorized modification, voids the limited warranty. Other panel makers have similar rules, so a clip-on method is the safer choice.

Animal damage itself is usually your cost to fix. Enphase's IQ8 microinverter warranty (effective October 2023, US and Canada) excludes damage from improper handling, "acts of nature," and service by anyone who is not an Enphase representative. It also does not pay for labor. Your installer's workmanship warranty may cover pest damage that happened because the array was built with gaps, but terms vary. Ask, and get the answer in writing.

If your system is leased or on a power purchase agreement (PPA), the company that owns the panels usually handles maintenance. Call them before you hire anyone. If your installer has closed down, see our guide for solar orphans on finding someone to service the system.

What pigeon proofing and pest repairs cost

We could not find an official or dated national price for bird mesh installation, so we are not giving one. Prices depend on the size of the array, roof pitch and how much cleanup is needed. Get two or three written quotes. Published ranges for related work, checked in November 2026, give a rough idea:

Item	Published range	Source (checked Nov. 2026)
Loose or chewed wiring repair	$100 to $400	HomeGuide and Angi
Minimum service call (job fee)	$100 to $250	HomeGuide
Panel cleaning	$10 to $20 per panel; $150 to $500 total	HomeGuide
Annual professional inspection (if not in your contract)	$150 to $350	HomeGuide
Solar pro hourly rate	About $100 per hour	Angi

Compare those numbers with the cost of doing nothing. A chewed cable means a service call plus repair. Debris matters too: Unirac says its guard prevents debris buildup under panels, "reducing fire risk and maintaining airflow."

Is it legal to remove pigeons from under solar panels?

For pigeons, generally yes. In its April 16, 2020 Federal Register notice, the U.S. Fish and Wildlife Service listed the rock pigeon (Columba livia) among species the Migratory Bird Treaty Act does not apply to. The same notice lists Old World sparrows, including the house sparrow, and most starlings.

Other birds are protected, and state or local rules can add limits. If you are not sure what is nesting, or if there are eggs or chicks, let a wildlife or pest pro identify the species and time the work. Many homeowners simply wait until a nest is empty and then seal the array.

When to call a pro instead of doing it yourself

Bird proofing means working on a roof next to live electrical equipment. Panels produce power whenever light hits them, so wiring under the array can be energized even with the inverter off. Call a pro if any of these apply:

• Your roof is steep, high or slippery, or you are not comfortable on ladders.
• You see damaged or chewed cables, or the inverter shows a fault.
• Production has dropped and you do not know why.
• Your lease, PPA or warranty requires authorized service.

Choose a solar service company or a pest firm that does solar bird proofing often. Ask how they attach the mesh, whether they drill anything, and whether they guarantee the work. Our guide to finding a solar repair company covers the questions to ask, and our page on critter guards and skirts goes deeper on the hardware.

Next steps

Check your array from the ground this week. If you see birds going in and out, book a cleanout and a clip-on mesh install before nesting season. Keep the invoice with your system papers. If you are looking for a company to do the work, start with our solar company reviews, and if your installer no longer exists, use our solar orphans resources.
