Hi, question. Carport sits on 18" of agricultural dirt, with varying layers of hard and soft caliche beneath. It is supported by 18 4ft rebar anchors and 6 4ft trailer anchors. My panels are secured to unistrut with steel bolts and square washers, and that unistut is bolted directly to carport tin roof. So, steel to steel to steel. Although no anchor is 8ft in ground it does seem to me that my panels are sufficiently grounded. Would I be wrong?
Note: an 8ft ground rod will still be set for chassis grounds.
