I haven't heard of anyone doing that, I think it's because of the size solar panel you would need, and what happens on a cloudy day?
I have seen guys use them on top of t-tops to recharge batteries, but they aren't very powerful and usually just help hold a charged batter on a trickle.

There was a guy I met in FTL that had a panel on his pier cart that he used to power the 5 gal bucket type of baitwell with the bubbler. I believe the bubbler was 3 volt.
