If you have solar panels and something doesn’t feel right — production looks lower, alerts are popping up, or you’re hearing movement on the roof — you’re not alone.
This is something we see a lot, especially in areas with trees.
Most of the time, the issue isn’t the panels themselves.
It’s what’s happening under them.
Why animals end up under solar panels
Solar panels create a warm, protected space that animals naturally look for. Squirrels, birds, and even raccoons can squeeze in and start nesting.
Once they’re under there, they’re close to wiring and electrical components — and that’s where problems usually start.
What typically goes wrong
When we inspect systems with animal activity, we often find:
- Chewed or exposed wiring
- Loose or damaged connections
- Nesting material packed under the panels
- Moisture trapped where it shouldn’t be
Sometimes the system still works for a while. Other times, it shuts down without much warning.
Common signs homeowners notice
People usually reach out after noticing:
- A drop in energy production
- Error messages from the inverter
- Scratching or movement sounds on the roof
- Birds or squirrels constantly hanging around the panels
If you’re seeing any of these, it’s usually a sign something needs attention.
About warranties (this surprises people)
Most solar warranties don’t cover animal damage. It’s typically considered outside interference, similar to storm debris or physical impact.
That’s why prevention ends up being important, especially after the system has been installed for a while.
How critter guards help
Critter guards are installed around the edges of the solar array to block animals from getting underneath while still allowing airflow.
When installed correctly, they:
- Prevent animals from nesting under panels
- Protect wiring and electrical components
- Reduce the chance of repeat repairs
It’s a straightforward solution that helps avoid bigger issues later.
If animals already got in
When damage is already present, the process usually includes:
- Removing nests and debris
- Repairing any damaged wiring
- Securing loose components
- Installing critter guards to prevent it from happening again
Addressing it early usually keeps the repair simple.
A quick note for solar homeowners
Solar systems are built to last, but like anything on a roof, they need a little protection. If something feels off, it’s better to have it looked at than to wait for a shutdown or safety issue.
