RE: Connectors for Solar
My solar panel setup uses Anderson Powerpole connectors throughout.

My setup is not permanently installed on the top, it's stored inside when
not parked.  When the panels are deployed (gee that sounds fancy) they
connect with  25ft of #10 zip cord pair
<http://www.powerwerx.com/wire-cable/red-black-zip-cord.html>
(very soft and flexible) at a connector just inside the rear hatch.  From
that connector is another piece of #10 going forward to under the rear seat
where the controller and the aux battery reside. The large Powerpole
connectors can be permanently mounted (two screws) if that is needed.  I can
shut the rear hatch down (though not latched) with the cables plugged in.
Since the panels are not working at night they get unplugged at the rear
hatch so the hatch can be closed. If I ever mount the solar panels on the
pop top I'll bring the wiring in through the top at the drivers side rear of
the top and down through the rear cabinets.
