Can anyone help with ideas for protecting a rooftop PV array from squirrels or other rodents chewing up PV wiring? Is this a problem?

Specifically, the USE2 PV cables connecting the modules of an array are exposed, and I know that rodents generally like to chew cable insulation. Has this been an issue with PV cables, and if so what do people do about preventing it?

One could put the wires between modules in conduit, but the junction boxes on the back of my panels do not have knockouts. Furthermore, to cut knockouts would violate module warrantees, and the MC4 connectors are 1" thick (need >1" ID conduit to fit through). One could also surround the entire array with a hardware cloth apron.

What do people out there do about this problem, if it is indeed a problem

Thanks.
