Keeping Critters Out From Under Your Solar Panels - A Plain-English Guide
Last verified: September 2026
The small air gap under roof-mounted panels is great for cooling and drainage — and, it turns out, pretty appealing to squirrels, chipmunks, and birds too. Here's what a critter guard is and how to handle an uninvited guest, safely. Rather talk it through? My number is (330) 200-8042.
Critter and Bird Guards, at a Glance
The small air gap under roof-mounted solar panels is good for cooling and drainage — and also an appealing, sheltered spot for squirrels, chipmunks, and especially birds and pigeons to nest. A critter guard, a mesh or metal barrier clipped around the array's perimeter, keeps wildlife out while leaving the gap free to do its job. This guide explains why it happens, what a guard does, and how to handle it humanely and safely if you already have a visitor. There's a printable page-by-page version up top.
Common Questions
1 Why do critters get under solar panels?
The small air gap under panels — there for cooling and drainage — looks like a dry, sheltered spot to squirrels, chipmunks, and especially birds and pigeons looking to nest.
2 What is a critter guard?
A mesh or metal barrier clipped around the perimeter of the array. It blocks wildlife from getting under the panels while still letting the gap breathe and drain normally.
3 Can a guard be added to panels I already have?
Yes — it's a common, straightforward retrofit that doesn't require removing your existing panels or racking.
4 Is chewed wiring under panels a real concern?
Yes. Beyond the mess and noise, damaged wiring under an array is a genuine safety and reliability issue worth having a professional look at promptly.
5 Can I remove a nest or clean up myself?
Please don't. It still means being on a roof around panels and wiring. Removal and cleanup should go through your installer or a qualified, humane wildlife professional.
6 Do guards harm the animals?
No. A well-installed guard simply blocks access — it doesn't harm wildlife, and any existing nest should be handled humanely by a qualified professional.
Would You Rather I Just Help?
Noises overhead or a mess under the eaves are one of the more common, and more fixable, solar calls I get. I'm glad to help you figure out what's going on and line up the right professional — with no stake in the sale. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
