Keep birds and pests out from under your panels
Solar Critter Guards
A perimeter installation of PVC-coated wire mesh that helps reduce nesting under rooftop solar panels, protecting wiring paths, panel undersides, and roof areas from birds, squirrels, rodents, and debris buildup along the array edge.
- Material
- PVC-coated wire mesh, 1/2" openings
- Fasteners
- Stainless steel or panel-compatible clips
- Coverage
- Full array perimeter
- Scope
- Exterior protection only
Why it matters
What critter guards actually does for you
Ends the repeat cleanup cycle
Nesting material, droppings, and debris come back every season until the access point is closed. The guard closes it.
Protects wiring from chewing
Squirrels and rodents gnaw exposed cable runs under panels. A perimeter barrier keeps them away from the wiring in the first place.
Preserves drainage and airflow
We fit the mesh so rain still runs off and air still moves under the modules — the panels need that gap to shed heat.
Restores your roofline
No more visible nests, straw, or streaking down the shingles below the array.
Which one are you?
Fixing a problem, or making sure you never have one
Both jobs use the same barrier. The difference is how much cleanup comes first.
Remediation — something is already up there
Nesting under a solar array is not a one-time mess. Birds return to the same site, and squirrels widen whatever gap they found. Until the perimeter is closed, you are paying for the same cleanup on a loop.
What we look for
- Scratching or scuffling overhead, usually loudest around dawn
- Droppings and streaking down the shingles below the array
- Straw, twigs, or insulation poking out from under the panel edge
- Gutters filling with the same debris a few weeks after every clean
- Birds landing repeatedly at one particular spot on the array
How the job runs
- Clear nesting material and debris out from under the array
- Clean up what it left on the roof and in the gutters below
- Photograph the condition of anything we find underneath
- Fit the mesh around the full perimeter so it cannot come back
On wiring: rodents chew cable, and we do sometimes find damaged or exposed conductors under an array. We will photograph it and tell you what we see — but we are not electricians and we do not repair it. That work belongs to a licensed electrician or your solar installer.
Prevention — closing it before anything moves in
A guard fitted to a clear array is the simpler job. There is nothing to remove, nothing to clean, and no damage to assess — the same barrier for less work.
A brand-new array
The gap under a new installation is open from day one. Nothing has moved in yet — which makes this the cheapest and least disruptive time to close it.
An older array that has stayed clear
Luck, mostly. Pest pressure changes as trees mature and neighbouring roofs get their own arrays. Closing the perimeter takes the variable out.
Trees close to the roofline
Overhanging branches are a direct route onto the roof for squirrels. If you have them, it is a question of when rather than if.
You are about to sell
A clean roofline with no nesting under the array is one less thing for an inspector to write up.
Not every system needs one. Homes with frequent pest activity, visible nesting, or recurring debris under the array usually benefit the most. Our recommendations stay focused on fit, performance, and long-term value instead of pushing unnecessary equipment.
What gets installed
A mesh barrier that disappears into the roofline
New systems often use a mesh roll of PVC-coated wire mesh or similar heavy duty material with 1/2-inch openings, attached with stainless steel clips or other panel-compatible clips for a secure fit around the module frame.
- PVC-coated wire mesh with 1/2-inch openings
- Attached with stainless steel clips or other panel-compatible clips
- Secured around the panel frame and module frame for a secure fit
- A discreet finish that supports airflow, drainage, and roof access
- Follows the array perimeter, helping block access to the panel underside
- Limits roofline mess, droppings, and trapped nesting material
Black finish, sitting flush against the module frame. From the ground, most homeowners cannot pick it out.

How it works
What the visit looks like
Inspect, recommend, do the work, review it with you. No surprises added at the end.
Inspection
Inspect the array perimeter, roof type, and access conditions, and check the current intake ventilation and exhaust ventilation.
Recommend
Recommend the right material, attachment method, vent size, and mounting style for the panel frame, module frame, and roof setup.
Install
Complete the installation neatly around exposed edges, sealing the unit for clean roof integration while preserving airflow, drainage, and rain runoff.
Review
Confirm operation, review the finished installation, and explain what to monitor over time.

Straight answers
Solar Critter Guards questions
Are solar critter guards worth it?
For many homes, yes, especially where birds or squirrels are active and cleanup keeps repeating. They help block nesting access and can reduce long-term mess around the roofline.
Will a critter guard system pay back the cost of the installation?
Absolutely! Installing a Critter Guard around your solar system is a smart investment that can easily pay for itself. Critter Guard protects your panels from birds, squirrels, and other wildlife that can chew wires or build nests, potentially causing thousands of dollars in damage and creating serious fire hazards. By preventing these costly issues, the Critter Guard not only safeguards your system but also ensures your solar panels continue operating efficiently and safely for years to come.
How much does a critter guard cost for solar panels?
Critter guard cost depends on array size, roof access, guard material, and whether replacement work is needed first. A quote after inspection is the best way to price the job accurately.
Do solar panels need a critter guard?
Not every system needs one. Homes with frequent pest activity, visible nesting, or recurring debris under the array usually benefit the most.
What is the 33% rule in solar panels?
That term is not a critter guard standard. It should not be used to decide whether you need pest exclusion around your array perimeter.
