Pigeons Under Solar Panels: Critter Guards $400 to $2,500

How much does solar panel critter guard cost

Published critter guard prices, newest first. Sources and dates per row; checked October 11, 2026.

Professional installation runs $400 to $800 in New England (NuWatt, April 2026) and $500 to $2,000 for a custom job (SolarReviews). Smart Energy USA, an installer, prices it at $8 to $15 per linear foot of array edge: $500 to $1,000 for 10 to 15 panels, $1,000 to $1,800 for 16 to 25 and $1,500 to $2,500 for 26 to 40, plus $200 to $500 to clean out existing nests. A DIY bird mesh kit is $60 to $200 (Fixr), but it still means working on the roof around an energized array.

Pigeons under solar panels

The gap under a rooftop array is shaded, dry and out of the wind, which is why pigeons move in. EnergySage notes that birds nesting under panels cause "a buildup of dirt and feces that can significantly lower panel efficiency." The fix is the same everywhere: clear the nests and droppings, check the wiring, and fasten mesh around the whole perimeter so they cannot get back in. Pigeons return to the same roof, so cleaning without a guard rarely lasts.

Rock pigeons are not protected by the federal Migratory Bird Treaty Act; the US Fish and Wildlife Service lists them among the non-native species the act does not cover, and European starlings and house sparrows fall outside it too. State and local rules can still apply.

Squirrels under solar panels

Squirrels are the bigger risk to the system itself. EnergySage notes that squirrels "sometimes nest under rooftop panels and chew through exposed or hanging wires." Chewed DC wiring under an array is a fire risk and can trip arc-fault protection. Heavier galvanized or stainless mesh, clipped every few inches, is the standard guard in the Northeast, the Mid-Atlantic and anywhere with oak trees. Smart Energy USA puts wiring repair after chewing at $500 to $1,500, more if the damage is extensive.

Birds nesting under solar panels

Most native birds are protected. Under a January 2025 Fish and Wildlife Service memorandum, destroying an in-use nest, one with eggs or nestlings, of a protected species requires federal authorization, while an inactive nest can be destroyed without a permit, though not kept or relocated. The practical rule: if a native bird is nesting under the array, wait until the young have left, then clear the nest and install the guard.

Signs of birds or squirrels under solar panels

• Birds entering and leaving the array edge.
• Droppings and debris on the roof below the panels, or nesting material sticking out at the edges.
• Chewed insulation on cables visible from the ground, or a panel reading zero in the app.
• Scratching in the attic below the array.

Why critter damage matters

Animal damage is not a manufacturing defect, so equipment warranties do not cover it, and an installer's workmanship warranty, if the installer still exists, usually excludes it. Many homeowners policies exclude damage from rodents. Prevention is the cheap option.

Solar panel bird proofing

Bird proofing a solar array means closing the gap between the panels and the roof so birds cannot nest there. The standard method is a galvanized or coated wire mesh clipped to the panel frames around the whole perimeter, after the existing nests and droppings are cleared and the wiring is checked. Clips attach to the frame without drilling, which keeps the panel warranty intact. The price is the same as a critter guard: $400 to $2,500 professionally installed in published ranges.
