If your talking about conduit runs between arrays, we've always used minerallac clamps to attach to either the riser, or the frame, depending on the tilt angle and accessibility. The inspector has always accepted this as bonding between arrays.....

How do we bond both ends of >the conduit? How about using a water pipe clamps on the EMT. A bare copper, # 6 or larger, should be able to be run outside the conduit, as it is a bond between sub arrays.
