Solar and Squirrels: How to Protect Your Panels

Like any part of your home, you want to make sure that your solar panels are kept safe from critters.

One question our installers hear frequently is: How do I protect my solar panels from squirrels? It’s an important topic, particularly for roof-mounted solar systems. Squirrels have a nasty habit of building nests in solar panels because they’re warm and provide shelter. The problem is that they can chew on wires, causing damage to your system and creating a fire hazard because of exposed wires. Fortunately, there are steps you can take to keep your home and system safe.

Trim Back Tree Branches

Smart home maintenance says you don’t want trees too close to your home for several reasons, but especially for solar owners—and not just because of shade. Squirrels typically get into systems by climbing out on limbs that grow too close to roofs. The solution here is to trim back any branches that approach your roof. And look at all sides of your home, not just where your system is.

Monitor Your System

All Granite State Solar systems come with monitoring. This can tell you how much power you’re producing, and it also sends out error messages. Know that squirrel damage isn’t the only explanation for an error message (for instance, you may get an error if snow is covering or partially covering your array – this is totally fine and will clear up when the snow does). If ever you see an error message that you’re concerned about, our team is always here to help you.

Invest in Squirrel Guards

If you live in a particularly woody area, consider installing a squirrel guard. Granite State Solar installs SnapNRack Critter Guards, specifically designed to keep all sorts of animals away from the technology under your panels.

If you suspect squirrel damage or see a nest in your system, contact Granite State Solar. We can help you diagnose and solve the problem.
