Protect Solar Panels from Shelter Searchers 9-30-22
Chelsea O'Donnell
Solar panels may be a step in the right direction in terms of energy efficiency, but one false move from a critter and your investment could be toast.
While great for absorbing heat, they also create shelter, offering two incentives for animals to build nests. Birds are one thing but small creatures such as squirrels will actually chew right through the solar panel wiring as well as the roof’s shingles, causing water to get to the plywood and into the attic. A fix entails removing the solar panels and patching the roof to ensure it wouldn’t be susceptible to more leaks in the future.
If you’re wondering how common this problem is, the answer is very. Once an animal has built a nest, it’s almost guaranteed that they are going to cause some damage unless its home is removed.
So what’s to stop the critters from coming back? If you’ve invested in solar panels, it’s worth also protecting them from potential damage. Most solar panel companies offer a guard that works just the same as a garden fence - it protects the solar panel and underlying roof from nesting birds and animals. Nests themselves reduce the airflow underneath a solar panel, causing the area to heat up and lessen the efficiency of the system. Animals like squirrels love to chew and wiring is just plain fun to chomp right through, so you need to stop them in their tracks.
If you’re just considering solar, don’t forget to ask your provider for an animal control solution. For those of you who have panels that aren’t protected, there are plenty of options available. To prevent unwanted guests, it’s simple to use wire mesh, but the key is to make sure there are no gaps as rodents can push themselves through tiny, seemingly impossible spaces. As with any roof work, don’t try to install a DIY solution yourself unless you are very comfortable on a ladder and have the proper safety equipment. A roofing contractor or your solar panel installer will be able to help you do the job safely.
