Critter guards/bird netting for solar panels: protect your system from squirrels & birds

A surprising threat to your solar panels may be the animals that live in the area surrounding your home. Birds and squirrels can damage your solar setup in several ways, leading to unwanted repair costs and headache. One solution to solar’s animal problem is to install “critter guards,” a physical barrier between your panels and the local fauna.

Why do you need a solar panel critter guard?

Home solar panels are typically installed on your roof, leaving them exposed not just to weather but also to local wildlife. In particular, birds and squirrels are known to cause damage to rooftop solar installations. Squirrels will sometimes nest under rooftop panels, and can chew through exposed or hanging wires. They can cut power lines from solar panels if they chew the right wire, leading to expensive repairs and power loss. Birds (such as pigeons) will also often nest under and around panels, causing a buildup of dirt and feces that can lower panel efficiency significantly.

Aside from local animals disturbing your solar system, environmental debris can also lead to panel damage. Dry leaves and twigs can build up under your panels, acting as a dangerous fire hazard near the electrical wires moving power from your panels to your home.

To combat damage from animals and the buildup of flammable materials, solar providers commonly offer “critter guards,” which are strips of metal screening resembling high-quality chicken wire that can be attached along the sides of rooftop panels. These are also sometimes referred to as “solar bird netting”. Because solar panels are installed with a gap between them and the roof for ventilation purposes, critter guards and bird netting can be installed to block squirrels and birds from getting under and between your panels and causing costly damage. They also block leaves, twigs, and other flammable debris from collecting under your panels and near the wiring, preventing a potential fire hazard.

How to get critter guards and bird netting for your solar panels

Many solar installers will offer to install critter guards with your new rooftop panel setup. If critter guards are something you might want to have installed with your panels, make sure to confirm with your solar installer that they can install them. If you decide you want to install guards post-installation, there are many places to find yourself a product. Companies like Snapnrack and SolaTrim manufacture different styles of critter guards, which are then sold to solar installers and resellers around the country.

When looking into critter guards, it is important to find a company that will install the guards for you, especially if you are looking to add them to an existing PV system. Attempting to install critter guards yourself can be physically dangerous, as well as dangerous to your existing system – rooftop solar setups can be complicated, and pulling a wire or shifting a panel by accident can compromise your entire system. It’s always best to let professional installers add critter guards for you.
