If I install EMT on the racking of a roof mounted solar array, UNDER the PV modules, is this considered to be exposed to sunlight?
But nevertheless, above the roof. Look at the exact wording of the rule: 310.15, 2011But the EMT will be shaded by the modules. So to me that means out of direct sunlight.
That seems to support you completely, but I would make sure that at no time during the day can sunlight get past the array to touch any part of the EMT run....exposed to direct sunlight on or above rooftops
IMO, some direct rays of sunlight getting through the "cracks" of the array should not satisfy the condition... but ultimately determined by AHJ. However, 310.15(A)(2) Exception can be argued as negating the direct rays portion.But nevertheless, above the roof. Look at the exact wording of the rule: 310.15

YMMV.
