How about extending your bonding wire out to the adjacent panels in roof areas with S5 clamps and attaching a ground lug to each instead of an L foot? I know it sounds a bit ridiculous, but an inexpensive and easy solution?
Michael D Nelson MD Electric & Solar, Inc. 707-684-0064 mobile 707-884-1862 office www.mdelectricsolar.com www.facebook.com/mdelectricandsolar Hey all, I had started a thread about bonding to metal roofs in 2018 but can't figure out how to respond via the archive. I know some things have changed since then, so I'm circling back and starting a new thread.
In NY one of our inspection agencies (NYSERDA) requires bonding of metal roof panels below the array, as well as within a 3' perimeter of the array. S-5! in combination with Ironridge is now listed to bond the roof under the array (so long as you hit every pan with an attachment) but this doesn't solve the problem of trying to bond within the 3' perimeter. For installs where we are only 18" from the ridge, this means we are required to bond the adjacent roof as well.
Whenever possible we install Illsco SGB-4 lugs under the ridge cap. But more and more we're finding roofs where the ridge cap feels inaccessible, tricky, or where we simply don't want to get into roof warranty issues associated with opening up a prior contractor's work.
Wondering if anyone else is coming up against this and what some possible creative solutions might be. I don't want to walk away from potential projects but...
As always, thanks for any thoughts Adam
