[RE-wrenches] squirrel problems

[Kirk Herander, VSE]

I just had to rewire an array because of squirrel damage. They chewed the
insulation off of the use-2 on almost every panel within 2 inches of the
j-box. This was discovered because the inverter GFI kept intermittently
tripping, so one of the uninsulated positive leads must have shorted to the
grounded array frame, verified by measurements and arcing.  At least the GFI
did its job.... We found a massive nest underneath the array. And I just got
another call from a customer with the same issue, although we don't know yet
if damage has happened. Both these arrays are mounted on Unirac Solarmount,
parallel to and stood off from the roof about 6 inches. I'm thinking of
skirting the perimeter of the array with a metal mesh of some sort. Any
other ideas? Thanks. Most likely they will come back if I do nothing.
