Quick Answer
To protect your solar wiring from rodents or pests, use rodent-resistant cable, bury wiring 12-18 inches deep, and install metal mesh or hardware cloth around the perimeter of your solar array.
Choosing Rodent-Resistant Cable
When selecting cable for your solar array, look for UL (Underwriters Laboratories) 2271 certification, which indicates that the cable has been tested for rodent resistance. This certification ensures that the cable is impervious to rodent damage. For example, Prysmian’s EVOLUX 500 cable is a popular choice for off-grid solar installations and meets this certification.
Burying Wiring for Rodent Protection
Burying your solar wiring can provide an added layer of protection against rodents and pests. Aim to bury the wiring 12-18 inches deep to prevent rodents from easily accessing it. Use a trenching tool or backhoe to dig the trench, and then lay the wiring in the trench, covering it with soil and compacting it to prevent settlement.
Installing Metal Mesh or Hardware Cloth
Installing metal mesh or hardware cloth around the perimeter of your solar array can help protect it from rodents and pests. This barrier should be at least 3 feet high and extend 12-18 inches below ground level to prevent rodents from burrowing underneath. Use a durable material like galvanized steel or aluminum, and ensure that the mesh is tightly secured to the surrounding structure.
