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

My calculator says 30 amps 22' #8 wire will lose less than 1 volt.
So you will have 16+ volts hitting the controller at full amp rating. Controller clips voltage to ~14.8 and you are good to go in all conditions.

Even #10 wire at 44' loses 2.7 volts putting 15 to the controller (17.9v - 2.7v =15.2v) and still good to go.
(I recommend #8)
