There many options.
I see that 24V is common. so....build a 24V system.
(12x12V 51W)-->(6x24V 102W)
+(2x12V 210W)-->(1x24V 420W)
+ (3x24V 235W)
------------------------------------------
=24V 757w
Does not do much good without an inverter and a charge controller.
It will work with setting up a 36v setup but I would have to put a 24 vdc and a 12vdc panel in series.
