Does the "little solar panel" have a charge controller wired with it? If it does, great--you can leave the panel hooked to the battery, with the battery cutoff in the "off" position, and it should do a fairly good job of keeping your battery charged up during storage time. It's probably a good idea to turn the cutoff back on after a week, go inside and check the battery indicator to see what's up, and check the battery with a good voltmeter too. If it seems to be full, turn the cutoff back to "off" and go have a beer.
Now, if the panel does not have a charge controller, you could actually overcharge your battery--the controller turns the current flow off when the battery is full to keep it from overcharging and damaging the battery. So in the case of "no controller," I'd only leave the panel on for short periods and keep a closer eye on your charge/voltage level.
