Looks like a really cool project. Is there a non-solar charging method, just in case? Have you done much testing in less than ideal solar locations?

There is! The solar charging should be enough for most everybody. We have done testing in a variety of locations. As a backup, though, it can be charged over USB.

Ahh, why not 12V?
