Quick Answer
Copper mesh is the best material for crafting homemade critter guards due to its effectiveness in deterring birds, bats, and other small animals from damaging solar panels. Its malleability and durability make it easy to shape and secure around panels. Its electrostatic properties also help to repel wildlife.
Choosing the Right Copper Mesh
When selecting a copper mesh for your homemade critter guard, consider the mesh size and thickness. A mesh size of 1/4 inch (6 mm) or smaller is recommended, as this will prevent larger animals from getting through while still allowing water and air to reach the solar panels. Choose a copper mesh with a thickness of at least 0.5 mm (0.02 inches) to ensure durability and prevent stretching or sagging.
Attaching the Copper Mesh
To attach the copper mesh to your solar panels, use a sturdy adhesive such as epoxy or silicone-based sealant. Apply the adhesive to the mesh and attach it to the frame of the solar panel, making sure to cover the entire surface. Use a level to ensure the mesh is straight and even, and clamp it in place while the adhesive dries.
