Looking for one to keep the battery charged between trips.

FWIW, we have a 5W panel on our A/C and it was able to keep 2 12V and 2 6V batteries in usable shape from Nov-May in Ottawa, Ontario, Canada and this is with snow (so panel was certainly completely covered some days and short winter days. But as others have mentioned, it's only able to maintain them if the disconnect switch is on (i.e. there is 0 load on the battery).
