Hilton, I can't speak to the specific NEC rules but my experience here (canadian electrical code) for PV or other electrical work has been that if metallic conduit in needed unless the requirement is specific for ridged metal conduit, then teck cable is fine.
My bet is that you are safe, but why don’t you just ask an electrical inspector in your area? I need to get my hands on a copy of the NEC so I can read the wording of the rules you guys are following.
