Solar critter guards (also called solar panel critter guards or squirrel protection) are physical barriers installed along the edges of rooftop solar panels. They close the open gaps underneath the array while still allowing airflow, keeping birds, squirrels, and other animals from nesting or chewing wiring.
Why Wildlife Is a Problem
Animals are drawn to the sheltered space under solar panels. Once there, they can:
- Chew through wires
- Build nests that trap heat and debris
- Cause system faults or reduced energy production
Damage often goes unnoticed until output drops or an inverter shows an error—leading to higher repair costs.
Do You Need Critter Guards?
Most homeowners with rooftop solar in Illinois and the St. Louis area benefit from them. If you have trees nearby, see frequent wildlife activity, or notice droppings, nesting material, or unexplained production losses, critter guard installation is a smart preventive step.
Even without current signs of animals, adding protection is relatively low-cost insurance for a system designed to last 25+ years.
Benefits of Installing Critter Guards
- Blocks animals from accessing the underside of panels
- Protects wiring from damage
- Helps maintain consistent energy production
- Reduces the risk of expensive repairs
- Supports longer system life
