Howdy, While I think it would be awesome - I don't think there are any solar panels efficient enough to charge near USB specs, that are that small. If you take a look at: http://yosemiteoutside.com/m/Blogs/02EA4A6B-8893-4F3E-87A8-C1E4B24C3AAB.html, he uses something called "PowerFilm" ( http://store.sundancesolar.com/po6v10flsopa.html ) for an iPod charger. Regardless of that, the solar panel is 6v @ 100mAh (which could be "adjusted" to meet get similar to USB specs). The problem is that the film is 4.5" X 5.9" for that "little" power. I really don't think the back of the Neo is enough room for a useful sized solar panel. Of course, that being said - a small solar panel could be used to trickle charge the battery. It won't give you 100% charge in the 5 hours you want - but at least it'll keep you running a little longer. -Jon PS. I'm no expert on solar panels, there may be better/more efficient panels to use.
