You would need a pretty big solar panel with a lot of current for it to charge it effectively. Car batteries are pretty powerful. Those little panels barely charge a phone battery, I've tried :/
Solar panels also need to be in direct sunlight and not behind glass to work effectively. Glass actually filters out a lot of the non-visible light, especially UV.
