Sizing the run

10 AWG carries a 30 A string with under 2 percent drop to about 60 ft one-way at 48 V nominal; past that, or on 12 V RV systems over 25 ft, step to 8 AWG (available on request). Order one red and one black per string, and add 10 percent to the measured path for drip loops and combiner entry. Voltage drop calculator · PV wire gauge guide
