We usually run a stranded equipment ground and tuck it in the module frame
with the PV conductors, to keep things tidy. However, using a larger, solid,
ground conductor for support of the PV conductors to the rack structure is a
good idea. I notice that the grounding point for these modules is in the top
of the frame, near the MC connector box, so this could work well.
Thanks,
