Wanted to do a sanity check that I wouldn't be crazy to try and pull (16) 10 AWG XHHW-2 wires plus one 4 AWG (one of the existing cables which I will reuse) through 1.5" conduit over 230ft. This is an existing underground conduit and I can't redo it. I'll be pulling out the existing wire and replacing it with the wires mentioned above. It is fairly straight shot and I might even dig down and temporarily remove one of the 90 degree elbows in the field where the solar array would be located for easier pull. I've done 500ft pulls in past but with only 3 larger cables. Just wonder about the logistics of 16 rolls of cable (plus the one larger one for ground) being pulled.
This would theoretically be for 8 separate strings of bifacial panels with 6 in series (250V Vmpp) if I decide to do that many with Isc of 13.64 under STC per string. I was going to use 12AWG but realized from discussion in another thread with @Hedges that would be too low of ampacity.
