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.)...

Avoiding shade is the most important. Why choose length? Carry a 25' and 50' and use the shortest combination of 25, 50, or 75' to stay in the sun.

Always better to have the controller close to the battery.
