<div dir="ltr">Please note we updated 2020 NEC 690.31(C)(1) to allow 24" between securing/supporting points for PV cable, and removed the problematic reference to 334.30. <div><br><div>The change was made because as you all know there is not always a way to secure wires within 12" of a box on the back of a PV module. Of course wires should definitely not be allowed to touch the roof but the hope is that 24" allows for proper wire management but with a little more freedom. </div><div><br></div><div>2023 NEC will update to 24" for \u2264 8awg, 54" for >8 awg.

The module is the half cut cell type with the DC leads coming from either side of the middle of the module. The modules come with the wires taped to the back of the module. If you remove that tape, there appears to be almost no way to properly manage those wires. Is that tape meant to just keep the wire on the back of the module forever? Would that even last more than a year? I am curious what other people have done for these if they have used them or something similar.
