Removing our rear A/C unit.... to install solar panels

I've got a 30' Itasca with two 15,000 BTU air conditioners. One is dedicated to the rear bedroom. I'm planning to remove the rear A/C so I have room for a large group of solar panels. We live in Northern CA and typically avoid the areas that have very hot summer. We also use lots of battery power when we're camped. Our 2012 rig has only 38 hours on it.

I'd love to hear some suggestions for closing up the A/C opening on the roof that is water tight.

Thanks
Class A

    14" sq box from plywood
    insert from inside the rv to flush with roof
    fasten fro the inside with screws into the frame members
    on top, seal edges with enternabond overlapped onto the roof
    paint the plywood with rubber roof coat, several coats
    cover the whole thing with a two foot sq of rubber roof material EPDM or TPO

    or you could just install a standard roof vent
    and mount panels high enough that they go over the vent

    If you're not going to cover the hole with the panels, clear Plexiglas. If you're going to cover the hole, then doesn't need to be clear....
