15 foot lengths of 10 AWG per panel should certainly handle the current without great V-drop (looks like 2.3%). Be sure that if you have more than two panels in parallel each has a fuse on it. These can be in the combiner box.
This would allow the use of the much cheaper PWM type controller.

Looks like you're on to a winner.
