You can make a floppy or a twirler. Both are shown here. If you want to make it easy, just use a dolly as was suggested earlier. It can twirl on its wheels and be propped up at different angles to suit the sun's altitude.
First I used the wooden tray on the roof for the single panel. It lies flat for travelling strapped to the cargo railing at the back of the roof, then on arrival I prop it up pointing South with a little stand I made or just against the air conditioner shroud.
