Hello Mark,
The best way to charge your batteries with a solar panel, in my opinion, is to use a car adapter on your charger. If you used an ac adapter and a solar panel that would probably work too but you would have to get a bigger solar panel because of the power losses in the ac dc conversion process. I can only guess what those losses would be but there will definitely be power losses when you use a power converter.
What you will need to do is to figure out - even if you have to guess - how fast your device(s) will use up the power that you expect to charge with a solar panel. i.e.- if your camera uses its battery in three hours of use, you will need to get a solar panel and charger combination that will charge your battery in approximately the same time. If your camera uses its battery in 2-3 hours and your solar charger set up takes 608 hours to charge, you will find it very hard to keep the battery charged - but this really depends on your expected use of the device(s) that will be charged. My opinion is tha tit is beter to have too much charge power available, and not need it, but that is my opinion.
Hope that helps.
Sincerely,
Curtis

| Hello, my name is Mark Kodiak Ukena, I will be hiking the Appalachian Trail starting this february of 2010, and was hoping to bring with me my Canon 5D, but I can't seem to find anything that will be able to charge my batteries while on the trail. The battery charger I have is a Canon CG - 580, INPUT: 100V - 240V 22VA(100V) -30VA(240V) OUTPUT: 8.4V DC 1.2A INPUT: 0.24A(100V) - 0.14(240V) E215051 The batteries are the BP - 511 7.4V 2000mAh Li-ion I figured that there isn't anything made yet to charge these by sun, do you have any suggested set-ups that would allow me to charge these, -like a roll-up solar panel, connecting to some kind of power converter with an AC outlet, so I could just plug the battery charger directly into it. I can't seem to find anything remotely close, what do you think? any help is greatly appreciated, if you have something I could purchase that could do this, that would be even better, thanks, Mark |
