Folks, I used an IronRidge design tool and I'm building a ground based PV array out of 2" galvanized steel schedule 40 pipe as the baseand universal strut as the panel mounting channels. Its understood that you have to 'ground' the solar panels... but I read somewhere that the metal framework holding up the panels also has to be grounded.
Does this mean that there has to be an electrical bond thru the whole structure (i.e. panels AND metal framework)? If so, are U bolts around 2" pipe to hold on the universal strut - i.e. u bolt touching 2" pipe and nuts touching the universal strut - considered 'bonded' for grounding purposes?
Advice on this welcome.
Here's a picture of the 2" galvanized steel framework to give you an idea but I haven't added the universal strut yet.
