It is the preferred gauge for longer DC string runs, high-current modules above 11A Isc, and commercial systems where voltage drop must stay below 1.5%. For residential installations with standard 400W modules and runs under 100 ft, 10 AWG 2000V PV wire is typically sufficient. NEC 690.8 sizing note: always apply temperature derating (Table 310.15) and bundling derating before finalizing gauge selection. On a 40°C rooftop with conduit in direct sun and 4 bundled conductors, effective 8 AWG ampacity drops from 55A to approximately 31A.
