Solar panels create a sheltered space beneath the array that can be attractive to squirrels, birds, and other small animals. Unfortunately, those unexpected guests can build nests, store debris, or chew on wiring—potentially leading to costly service work and system downtime.

Critter Guard is a durable mesh barrier installed around the perimeter of a solar array. It is designed to block animals from getting underneath the panels while still allowing proper airflow and drainage. Because the mesh is low-profile, it is typically difficult to notice from the ground and does not interfere with normal solar production.

For many homeowners, Critter Guard is inexpensive protection for a much larger investment. Installing it when a solar system is new can be especially convenient, since crews already have safe roof access and can fit the barrier neatly around the array. A little prevention today can help protect wiring, roofing, and long-term system reliability for years to come.
