Our 3 x 100w Mandrake panels are stored and transported in a 3 bay frame on top of the front box on the Coota.
A steel rod through the lot, with a pad lock at each end, helps them stay there until I want them somewhere else.
They're wired into the system, so when the alternator is having a little rest, the sun takes over.
Once at camp, the panels can be slid out of the frame and set-up individually, or grouped together and wheeled around as a unit.
Pretty clever, huh??....
