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

CWJ8, and Mr Wizard you understood without me being wordy.
For the more challenged, especially me.......I've got 2 160w panels (a 3rd is unlikely) I'll be wiring 22' 1 way to a PWM controller, then another 2' to the batteries. Their specs are VOC-22.4v, VOP-17.9v, ISC-9.87a, IOP-8.89a. These specs are likely inflated and come from a perfect world without temperature variables. (Depending on wire size) I've no idea what voltage or amps can REALLY make it to the controller or batteries. Bigger wire size helps and with a voltage drop calculator I might not have to throw darts at a reasonable size to use. I'm wanting to know the likely real world volts and amps to use with a voltage drop calculator.
