Critter guards

These guards, typically made from materials like PVC-coated galvanized steel mesh or metal screening, help protect solar panels from potential damage caused by these animals. The primary benefits of installing critter guards include:

1. Protection of Wires: Squirrels and other rodents can chew through the wires of your solar panels, leading to costly repairs and power loss.
   
2. Prevention of Nesting: Birds often build nests under solar panels, which can lead to a buildup of debris that reduces the efficiency of the panels and poses a fire risk.
3. Debris Mitigation: Critter guards prevent the accumulation of dry leaves and other flammable materials under the panels, reducing the risk of fire.

Critter guards can be installed either during the initial installation of the solar panels or as an aftermarket addition. They are especially recommended for homes in areas with high populations of small animals and birds. The cost of installing critter guards can vary, ranging from around $40 for DIY kits to upwards of $2,000 for professional installations.

Regular maintenance and inspection of the critter guards are important to ensure they remain effective. This includes checking for damage, cleaning any debris, and repairing or replacing any compromised sections.

Overall, while critter guards are not mandatory for every solar installation, they can be a worthwhile investment for those looking to protect their solar panels and maintain their efficiency over time.
