Carl just the suggestion that each metal roof panel be grounded is scary. There are probably no panels in existence with manufacturer installed grounding points potentially making any metal roof non-qualified for a PV installation using S5 clamps. This scenario was discussed a number of years ago on this or some other site. While it may come across as absurd for any AHJ to make such a call, it is entirely feasible.

I did not find any discussions on module grounding on this type of installation or any requirements for grounding the metal roof to which the modules are attached. It has been suggested to me that each roof pan which has a module attached should be grounded (perhaps under the ridge cap). Can anyone offer suggested best practice or requirements regarding this?
