How about hardware cloth along the back of the array beneath the rails?
I think that's been suggested on this list before.

Subject: [RE-wrenches] Ground Mount Screening

Hello Wrenches,
We are installing a ground mount system with Enphase inverters. 690.31
requires readily accessible source and output conductors OPERATING at
over 30 volts to be installed in a raceway. The Vmp of the REC230PE
modules is 29.4 volts. Of course it would go higher in cold weather. Do
I have any argument that would allow us to not install the DC conductors
in a raceway?
The NEC Handbook comments "Most PV modules do not have provisions for
attaching raceways. These circuits may have to be made "not readily
accessible" by use of physical barriers such as wire screening".
I have heard of a green screening material that has been used on the E,
W and N sides of ground mounts to render the area not readily
accessible. Does anyone know what this is? What else would work that
would be more cost effective than running a chain link fence around the
array?
Thanks,
Drake
