What Voltage would you use for a wire size calculator?
There is the fact that it is a 12 Volt panel, Its open circuit voltage it 21.2, and the optimum operating voltage is 17.7 VDC. My gut tells me I need to use the more conservative leading to the thicker wire size, so 12 Volts. I'm trying to calculate what size wire I need for a 600 Watt system, and there's bit of difference in AWG for a 10' run based off voltage.
