Bird & Critter Guard Installation
The gap under your solar panels is an ideal nesting spot for pigeons and other birds — and it's a genuine fire and wiring hazard, not just a mess. Guard mesh keeps them out for good.
If you’ve heard cooing, scratching, or noticed droppings streaking down from under your solar array, you likely have birds — usually pigeons — nesting in the gap between your panels and your roof.
Why This Matters Beyond the Noise
Fire risk. Nesting material like twigs and dried grass builds up near wiring and electrical connections under your panels. That’s a genuine, not hypothetical, fire hazard.
Wiring and roof damage. Nests and accumulated droppings can degrade wiring insulation and roofing material over time. Bird droppings are acidic and will accelerate wear on roofing and panel frames if left in place.
It keeps coming back. Pigeons are creatures of habit — once a spot becomes a reliable nesting site, the same birds (and their offspring) tend to return year after year unless something physically blocks access.
Where This Comes Up Most in SLO County
Coastal and tree-adjacent communities see this most — Morro Bay, Los Osos, and Cambria’s mix of open space, ranchland, and tree cover correlates with higher bird activity than denser urban areas, though it’s a countywide issue anywhere panels create a sheltered gap.
What We Install
Bird and critter guard consists of galvanized or coated wire mesh installed around the perimeter and gaps of your solar array, physically blocking access to the space underneath while remaining unobtrusive from ground level. It doesn’t cover any part of the panels themselves, so there’s zero impact on energy output.
If Birds Are Already Nesting
If you have an active nest, we recommend nest removal and sanitizing first — clearing out existing material and cleaning up droppings and pheromone residue that would otherwise attract birds right back — before mesh goes in. Installing guard mesh over an active nest just traps the problem underneath. See our Bird Nest Removal & Sanitizing service for that step.
What It Costs
Complete guard mesh installation typically runs $800–$2,000, depending on the size of your array and the complexity of your roofline. If nest removal is needed first, that’s quoted separately (typically $200–$500) before installation begins. We’ll assess your specific roof and give you an accurate combined quote.

Bird & Critter Guard Installation FAQ
Why do birds like nesting under solar panels so much?
The gap between panels and your roof is sheltered from weather and predators, elevated, and generally undisturbed — basically an ideal nesting spot from a bird's perspective. Pigeons in particular are creatures of habit and will return to a good nesting spot year after year once established.
Is bird nesting under panels actually dangerous, or just annoying?
Both. Beyond the noise and mess (droppings staining your roof and panels, feathers and debris), nesting material — twigs, dried grass — is a real fire hazard when it accumulates near wiring and electrical connections. Nests and droppings can also damage wiring insulation and roofing material over time, and the acidic droppings themselves can degrade roofing and panel frames.
How is guard installation different from just cleaning up an existing nest?
Nest removal and sanitizing addresses an active problem — clearing out existing nests, droppings, and pheromone residue that attracts birds back. Guard installation is the preventive fix: mesh that physically blocks birds from getting under the panels in the first place. If you currently have an active nest, we typically recommend removal and sanitizing first, then guard installation, so mesh isn't sealing birds in.
Does the mesh affect how well my panels work?
No — guard mesh is installed around the edges and gaps of your array, not over the panels themselves, so it has no effect on sunlight reaching the cells or your system's output.
