So would the best way to configure these 6 panels is in a parallel config, or 3 strings of 2 in series.

It is up to you, you will save some wire ($) if you go 3 x 2 over 6 parallel. You will lose a bit of energy as heat in the CC though, at 3x2 as you are down converting from '24v' nominal to 12 v.

eg. Due to distances mine will be 48V to 24V so I save on copper and line loss, cool location so a bit more heat.
