$10 a watt, yikers!
Phil, 24v mono's can be pretty big and heavy. Two as a suitcase could be rather hard to manage. Just something to consider.
But yes, going 24v will decrease wire size. Mex pointed out to me the idea of going 12v in series, and bucking the voltage at the panels with a gizmo. That may be a viable way for you to go? I mainly went with heavy (6ga welding) cable, in hopes of it being more durable in the long term, and to accommodate going 12v in parallel.
It seems from my gizmo adventures that the gizmo required is not just the ordinary buck converter, but one that has extra circuitry to prevent the coil from being saturated. You get one of those in an MPPT controller, and it turns out that could be less expensive for all its features than using gizmos.
