Research around solar panels and critters is mixed – it’s unclear the degree to which home solar panels may lead to animal problems. It’s important to note that there is a gap between your solar panels and your roof where critters may nest. If you’re concerned about critters, we recommend you ask your solar installer about a critter guard. The recommended critter guard is a malleable metal screening installed around your solar panels to block off the gap between your solar panels and your roof.
