Anyone who has designed or built their own solar system, either mobile or fixed, have any recommendations for PV wire brand and supplier? I’m facing total degradation of the insulation on my home panel array, and have discovered the people that built it did so with standard THHN laying in the sun on the roof and draped over the racking. 15 years later, I have ground faults and short circuits to spare, so I’m working on a plan to re-wire the whole system. I’m guessing a 250-500’ roll would get the job done. Suggestions or experiences are appreciated!
