This question has never been about whether or not you can buy the parts - it's about if there's something idiot proof that does it all for you. I'm not an electrician or a physicist. The finer points of electrical engineering are Greek to me. That's a lie, I actually know more Greek than I do electrical engineering. | |

| May 15, 2013 at 12:57 | comment | added | Arne | Yeah, you're right. You need more than one panel to both power the Pi and charge the battery. However, if you are willing to charge the battery every couple of weeks using a conventional charger, you may need less panels. :) | |
| May 15, 2013 at 10:30 | comment | added | lenik | @Arne (24 hours * 0.7A) / (8h * 350mA) * $139 = $834 just to make it even. How did you arrive to the 200 USD figure? | |
| May 15, 2013 at 9:58 | comment | added | Arne | There seem to be solar panels with chargers for car batteries: batterystuff.com/solar-chargers/SP-5.html. @XAleXOwnZX mentioned that the car battery may last the Pi a week at least. If there's sun, you can recharge it using the above panel. Sounds like you may get away with 200 USD for the panel with charger, a battery plus you need a small 12V-5V adaptor. | |
