Critter guards are protective barriers installed along the edges of the PV racking system to prevent animals from damaging any wiring beneath the solar array(s); they are often constructed from a coated reinforced aluminum for added weather resistance.
The mesh is designed to be strong enough to withstand chewing or clawing from animals like birds, squirrels and raccoons while still allowing for airflow underneath the panels. In addition to preventing electrical issues from animals, critter guards also help reduce the buildup of debris beneath the solar system.
Installing critter guards will extend the lifespan of your solar system and prevent unnecessary maintenance. They are a simple and cost-effective way to protect your solar investment and ensure its safety and reliability for years to come.
