So as not to completely get off topic in one of Kev's threads, I'm posting my solar power stuff here.
Let me know what you think.
PowerFilm 10 watt solar panel
Nitecore usb battery charger
I can plug a usb cable or an Apple Lightning Cable right into the usb adapter
the battery charger...
OK, so I bought a little 20W solar panel off amazon to start tinkering and learning solar power. I have the panel itself, the little charge controller, and I plan to get a AA/AAA battery charger with a car adapter, and a 12V automotive socket. The instructions with this little panel were ... ah...
I found this article on how to make a 1volt solar panel with simple supplies cheap.
By soldering 12 together you could charge a car battery to power other things, perhaps hook it to a DC-AC adapter to run house...
