That's a great idea on the solar panel. Surprised that it only gives you 15 watts though, I had one roughly double in size that was rated at 80 watts.
Regardless, you're re-charging your battery at roughly 1.2 amps in best-case scenario, but even half that should be enough to keep your battery charged. Awesome!
