What is Critter Guard

Critter guard is a heavy-duty, narrow-gauge galvanized steel wire mesh coated in weather-resistant black PVC, to blend into the shadows of the solar array. This mesh material is fastened directly to the bottom frame of the solar modules using specialized nylon clips. These mechanical fasteners do not require drilling into the panels, ensuring that the manufacturer’s equipment warranty remains valid. The ½ in x ½ in grid pattern blocks pests while maintaining optimal airflow and water drainage beneath the panels, which keeps the system from overheating or losing efficiency.

Why Critter Guard Installation Is Essential

Rooftop solar panels create a warm, protected gap that acts as an ideal nesting ground for pests. Without a physical barrier, birds, squirrels, and rodents can cause devastating structural and electrical damage to your solar investment. Because solar panels are elevated a few inches off the roof on racking, they create a warm, shaded, and sheltered cavity that acts as an ideal nesting ground for pests like squirrels, pigeons, and racoons. Critter guard functions as a protective shield for this gap.

Our Core Specialization

Critter guard installation is not just an add-on option—it is one of our company’s s specialization.

  • Proven Expertise: We have successfully protected systems and completed hundreds of custom guard installations.
  • Premium Heavy-Duty Materials: We use only black PVC-coated galvanized steel mesh that resists rust, weather, and determined chewing.
  • No-Drill Fastening: Our team utilizes specialized nylon speed clips that securely grip the panel flange, ensuring your solar manufacturer warranty remains 100% intact.
  • Full-System Remediation: Before every installation, we thoroughly inspect under each array, and if necessary, remove all existing nests and waste.
  • Certified Technicians: Every installation is performed by trained experts who prioritize quality and ensure that the entire perimeter is complete entry-free.

Preventing Severe Property Damage

  • Prevents Wire Damage: Rodents—especially squirrels—frequently chew through exposed DC wiring, leading to arc faults, system shorting, and severe roof fire hazards.
  • Blocks Nesting: Birds, pigeons and raccoons use the nest, leaving behind highly corrosive droppings (creating highly unsanitary conditions), foul odors, and debris. At times, many rodents can die under the panels due to the heat caused under the panels.
  • Mitigates Debris Buildup: The mesh blocks leaves, twigs, and pine needles from accumulating under the array, reducing moisture trapping that accelerates roof shingle rot. Trapped debris retains moisture, rotting your roof shingles and causing costly structural leaks.
  • Eliminates Fire Hazards: Accumulated nesting materials like twigs, leaves, and dried grass can easily ignite from electrical sparks, especially if wires are exposed from chewing.
  • Avoids Out-of-Pocket Repairs: Most standard solar manufacturer warranties and homeowner insurance policies do not cover wildlife or pest damage. Once damage is done, it is up to the homeowner to cover the costs.
  • Saves on Remediation: Installing a barrier upfront will cost a fraction of the price of professional animal removal, wire splicing, panel replacement and/or roof repair on top of installing critter guard to prevent future damage.
