Solar Panel Critter Guards: Best Types and Trusted Brands

A critter guard is a protective barrier—typically a mesh or skirt—installed around the perimeter of your solar panels. Its main purpose is to keep animals like birds, squirrels, and rodents from nesting underneath the panels or chewing on exposed wires. As outlined by NuWatt Energy, critter guards help preserve the efficiency, safety, and longevity of your solar system by preventing structural and electrical damage caused by pests.

1. Galvanized Steel Wire Mesh Guards

This is the most commonly used type of critter guard. It’s installed around the outer edges of your solar panels and made of galvanized steel mesh. While some installers may use stainless steel in rare cases, most commercial products use galvanized or PVC-coated steel for easier installation and adequate protection.

Benefits:

• Deters birds, squirrels, and other small animals
• Rust- and corrosion-resistant for long-term use
• Allows ventilation and doesn’t interfere with solar performance

2. Aluminum Skirt Guards

Aluminum skirt guards provide a rigid, visually appealing finish around the base of solar panels. They are beneficial for homes that value both protection and clean aesthetics.
