Hey Dan! If you're trying to maintain a battery while your vehicle sits for a long period of time you can use the OptiMate Solar Duo Portable Solar Panel with Controller # MA56JR. This has a 40 watt solar panel with a stand so you can sit wherever you want. If you're looking for something a little smaller we also have the # MA89JR and # MA69JR which mount using suction cups or can be permanently mounted with standard hardware.
