I use standard THWN-2 green of the appropriate size. Ground wire does not have to have the 1,000Vrating, as the copper inside is at 0 Vdc to ground (at least we hope it is J). Remember that EGC's can actually be bare copper (NEC 250.119), think of the ground wire in ROMEX, or the bare copper you see grounding light fixtures from IKEA... But if it's insulated or covered, it has to be green or green with yellow stripes. We don't normally have them bare in a PV install because we use metallic conduit and you don't touch bare copper to metallic conduits, not to mention insulated stranded wire is much easier to pull.
