Your 10 gauge wire will safely handle 24 amps at an 80% loading factor, since they are generally rated for 30 amps. If your batteries are fully charged, the energy created by the panels is virtually wasted as it has nowhere to go, other than to continuously top off your batteries. I would agree with the series parallel combination, seeking as close to 30amps as possible on a normal day, achieving the best performance and maximum output.
