We have always run paired positive and negative conductors in conduit so the question had never occurred to me. Obviously, you have to bond both ends of the conduit if it is over 250 v.

Any wire I use on the roof is rated for that type of service and I have some off-grid systems that have been in the sun for some 25 years where the wire still looks nearly new even when flexing it to look for checking/cracks. It seems the wire/insulation can take it, thus it seems like the key to "wire management is to keep the wire from moving and off the roof, secured to the racking, thus not compromising the insulation. </p>
