What solar panel specs are used for calculating voltage loss
Which solar panel specs are reasonably used for calculating line voltage loss?

Its not worth even thinking about if only a few hundred watts on the higher voltage. Just run a 10 ga cable for every 10-12 amps. I ran the first 2 panels on one 10 ga cable. When I got the 3rd panel I ran a 2nd cable, which will be good for a 4th if ever.
Concentrate more on the total amps from the controller on their way to the batteries, that's where the loss will make a difference.
