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.)...

Once in the sun all day worth rotating tilted array three times.
Sunset to SE
Mid morning to S
Mid afternoon to SW

Also tilt lower mid day with sun higher

Eg 130W in May at 49N daily AH haul

Flat 56
South tilted all day 70
Tilted rotate three times 90

OP 110AH batt 50% needs 55 plus 5 for heat so
60 is in range after using some to run things during daylight too and 120W other times of year and latitudes
