That being said, I really always liked the idea of putting solar panels pretty much everywhere. But price and and size is kind of an issue. Provided that the electronics would fit, and the OW gets changed into another version further down the road. There could possibly be a fold-able solar panel tucked away somewhere. I mean this highly theoretically, because it would make the whole thing cost a lot more, and probably not be of that much use to most people. Compared to say a "swap-able battery solution".
