Yes, you can get a solar battery maintainer that will do the job, but for almost the same money you can get "some solar" that will do that plus help while camping if you ever camp off grid.
You can get portable (or installed on roof for more money for the installation cost), but then you might have problems with shifting the portable with the neck problem, don't know.
IMO do anything to avoid the rip-off hardware store low watt "solar" at $5 per watt compared with getting a real solar set from a real solar dealer at $2 per watt or less.
