If your solar panels are up and running smoothly, you might think you don’t need a critter guard. And hey, maybe you’ve never seen a squirrel up there or heard a peep from your roof. But here’s the thing: when critter damage starts, it usually happens quietly and it gets expensive fast.
Let us walk you through what really happens when you skip installing a critter guard.

1. Animals Move in Fast
Once your panels are up, they create the perfect little hideaway for animals.
There’s just enough space underneath for squirrels, birds, raccoons, you name it.
It’s warm, dry, and sheltered. In other words: the dream apartment for a critter.
And once they find it, they’re not leaving without a fight.
2. They Start Nesting or Chewing (or Both)
Here’s where the real trouble starts. Animals don’t just sit quietly under your panels. They chew wires, pull out insulation, and build nests.Birds drop feathers and debris, squirrels gnaw through the coating on wires, and raccoons can even lift or shift panels trying to get inside.
You might not notice anything at first. But over time, the system starts losing power and that’s when the damage becomes clear.


3. Your System Efficiency Drops
When animals are nesting or blocking ventilation under your panels, airflow suffers.
That leads to higher heat buildup and lower energy production.
So now you’re getting less power from your panels, and your utility bill starts creeping back up.
4. You’re Left Paying for Repairs
Chewed wires? That’s not covered by every warranty. Some manufacturers consider animal damage an external factor and that means you pay out of pocket. And solar repairs aren’t cheap. Replacing wiring, reconnecting panels, or dealing with short circuits can cost hundreds, sometimes more.
Installing a critter guard early prevents all of this and keeps those repair bills off your plate.


5. Roof Damage Can Follow
Animals don’t always stop at the panels. In some cases, we’ve seen squirrels chew through roof edges or burrow into attic vents after starting under solar systems. That turns a small issue into a full-blown roof problem.
Critter guards act as a barrier that keeps animals from even getting that far.
Final Thought: It’s Not Just About the Panels
When you skip a critter guard, you’re not just risking your solar panels, you’re risking your roof, your wiring, and your energy savings. Most homeowners don’t realize the damage until it’s already done. And by then, they’re paying for repairs that could’ve easily been avoided.
