And that GEC/GE must then also be bonded to the existing premise grounding
system.

Drake,

Yes, it really is up in the air, and I am seeing it along different lines.

Most roofs are much more than 6 feet of an electrode.

The intent may have been that you take the most direct route from the array,
down along the side of the building to the ground and put your "additional
electrode" there.  If that is within six feet of the existing premise
electrode, then don't put in the additional electrode.

In any case, you have to run an additional GEC (separate from the DC system
GEC/EGC run as a single conductor from the inverter) from the array to this
new GE.
