I found a company, Electriduct that makes a UV resistant wire loom tubing but only in black. They make white tubing, but not UV resistant. Compared to having red and black cables on the roof, a black wire loom isn't horrible. I don't know many people who are 10' tall and will see itProbably is 2" X 2". The first roll I used for installation was a 4" Eternabond Roof tape. That ran out and I started to use Dicor Roof tape I picked up off the shelf at a local Camping World. I Do cut the roofing tape into a square so its a bit bigger than the mount and will secure it. Got the method from this guy at 2:45 in
The PV wire I use is 10 AWG on the roof. That is here: https://www.wireandcableyourway.com/solar-photovoltaic-pv-wire. There is some 6 AWG wire in the area, but I don't think it made the pick.
Even though the PV wire was UV rated, to make the installation look better, I bought 100' of white split loom wire off E-Bay at this place: https://www.ebay.com/itm/131571481083. Could be that because the split loom is not UV resistant, I may need to replace in a few months. I may just take a split loom and paint it white.
Seems the 1/2" OD (.47 ID) should be large enough for a pair of PV cables. Do you remember the diameter of your tubing?
I bought one of those 20' extension OV cables I hope is long enough.
