Control wiring for boilers - 70 VA at 24 VAC requires nothing and is run in T-stat bell wire.
Q -Why 12VDC @ ? amps require EMT? Q - Is the PV circuit fused or breaker protected at the roof? Could it be? I have run numerous 12 & 24 VDC pumps on a circ pumps on many jobs with SO cord and never had an issue. See if this falls under heating low voltage circuits?

The wiring is run through the attic and down to the pump near the water heater. I've never ran into this before (but I have run into this inspector). :) Jason Szumlanski Fafco Solar
