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

controller set point is currently 14.4
currently measuring 14.04 out at 20.59 amps
input voltage is 15.71
output is being read on a turnigy power meter
input is read with a Fluke 77 at the input wiring to the controller
the controller is the xantrex C-40
the wire run to the batteries is 4ga
voltage at batteries is 13.2v yes there is drop
my battery compartment is behind the rear wheels on passenger side and exposed to the elements, batteries get very dirty
controller is in storage compartment before the rear wheels
that was close as i could get and have it accessible, did nor want it under the bedroom closet behind the drawers, and that is where the wire goes to get thru the floor to the batteries
and there are loads, this PC and 5 small 120v fans and Fantastic vent fan on low (and ol yeah the fridge cycling)
when batteries are charged/nearly charged and only the fan loads are present voltage at battery is 14.1v
these fans have been running non-stop (except for dusting) for over a month, they are on, except for cleaning, until Fall weather arrives
as a side note the system hit 31.15 peak amps yesterday, 436.3 peak watts 1624.5 wHrs
the solar weather has been great this week NOT too hot
when its too hot (like it had been) all we can do is hide in full shade and run the Generator and A/C
