Break-even point between cable length and voltage drop?

I have two cables for my portable solar panel – one is 40 feet long, and the other is 70 feet long. (We boondock, and we like to park the trailer in deep shade and put the panel out in the open sun.)...

Just saw some of the prior posts. NOTE OP stated his controller is built into the panel and hence the wiring loss due to the cable is more significant and series panels/MPPT are not a option. But good considerations for a new setup.


most controllers attached to panels are easily removeable and then can be placed close to the batteries either permanently in the pass through or portable outside. Solves the problem.
