This seem ridiculous to me..... the idea that an inspector is having you ground a hot water collector is akin to requiring a pressure relief valve on a pv module. Or am I missing something here? Ask the manufacturer of the hot water panel where in the UL listed connection point for the bonding point is. If required (oh the horror) then there will be one. They manu will most likely just laugh or say "wha?" In any case, the plumbing (copper?), unless isolated from the household by di-electrics, is grounded quite nicely and can serve as your 'ground' path. Pat Redgate Ameco Solar, Inc.
