Illinois is squirrel country. And pigeons don't migrate. The space under your rooftop solar panels is exactly what they're looking for — dark, elevated, weatherproof, and warm. Once they move in, the damage starts immediately.
Panel manufacturers and inverter brands explicitly exclude animal damage from their warranties. If squirrels chew your wiring, you're paying out of pocket — regardless of how new your system is.
Chewed DC wiring is a serious fire risk. Solar systems run at high DC voltages — damaged insulation can cause arcing. This is not hypothetical; animal-caused solar fires have been documented across the Midwest.
Nesting debris under panels traps heat and blocks airflow. Solar panels lose efficiency as temperature rises — you may be losing 10–20% output without realizing it.
It's not a trap. It's not poison. It's a physical barrier — the only permanent solution.
We install galvanized or aluminum mesh wire around the full perimeter of your solar array. The mesh is rigid enough to resist gnawing and sized to block even small birds.
The mesh is secured using stainless steel clips that attach directly to your panel frames — no drilling into your roof, no penetrations, no warranty issues with your panels.
Every gap is sealed — sides, corners, and any irregular edges. We inspect as we go to ensure there are no entry points remaining. Animals are persistent; the installation has to be complete.
We assess your array layout, panel spacing, and check for any existing animal activity or damage before starting.
If animals have already been nesting, we remove all debris before sealing — leaving behind nesting material creates odors that attract new animals.
Heavy-gauge mesh is cut to fit and secured with stainless steel panel clips around the entire array perimeter, sealing every gap.
We walk the full perimeter, check every corner and junction, and confirm no gaps remain before leaving. You get a clean, sealed system.
Illinois-specific: The Midwest's large squirrel population and year-round pigeon presence make Illinois one of the highest-risk states for solar panel animal damage. Most installers don't include critter guard by default — it's an add-on that pays for itself many times over.
The #1 threat to Illinois solar systems. They gnaw through wiring, build large nests, and can completely disable a system. Active year-round.
Pigeons don't migrate and don't stop. Highly acidic droppings corrode hardware. Nests can accumulate for years if not blocked early.
Small birds build compact nests in tight panel gaps. They're quiet enough that you may not notice until significant debris has accumulated.
Less common on rooftops but not unheard of in urban areas. They follow squirrels and are equally destructive to wiring and insulation.
Critter guard isn't just about protecting your investment — it's genuinely the more humane outcome for the animals too. Squirrels and birds that nest under solar panels are exposed to serious risks: DC electrical wiring at high voltage, sharp panel edges and metal hardware, and no safe exit if a panel shifts or an installer works on the roof. Pigeons that roost in tight spaces can become trapped or injured by moving parts.
By sealing the perimeter before animals move in, critter guard redirects them to safer, natural nesting spots — trees, eaves, and ground burrows — where they belong. No traps, no poison, no harm. Just a physical barrier that keeps your system safe and keeps the animals where they're safer too.
No surprises. We price at $0.20/watt for roof pitches 32° and under. Steeper pitches are assessed on-site.
*Flat-rate pricing at $0.20/watt applies to systems on roofs with a pitch of 32° or less. Steeper roof pitches require additional safety rigging and are priced by on-site assessment. Final cost determined by system size and number of arrays. Get a free quote for your exact system.
Most pest control companies have never been on a solar roof. They don't know panel frame types, module layouts, or how to work around wiring without creating new problems. We do this every day — because we install and service solar systems across Illinois.
The gold standard in solar installation. We understand your system from the ground up.

"He is HONEST, thorough, respectful, follows the law and takes no shortcuts. In my 76 years I can't think of another consumer experience that is close to this one. #1 and no close 2nd."
"Jonathan just finished a project for us and we couldn't be happier! He was extremely professional and kind, and he KNOWS his stuff. He even brought his own house slippers to keep our floors clean. Highly recommend!"
"Very prompt and professional. From requesting a quote to finished — including ordering parts — was a remarkably short amount of time. His price was fair. Highly recommend."
