solar energy

Im very new to electronics, say that i had something like a cellphone or mp3 player charging through solar power, would I just attach as many solar pannels as i please and wire them into the usb to whatever ipod uses cable? I assume that there would be some extra parts that i would have to put in like resistors and such. but what would i need?

You'll at least need a diode to stop current flowing back through the cells when it goes dark.

This link leads to the most basic circuit I could find.

in that circuit the cells lead to two AA's , i know that there are instructables on charging ipods through AA's, if i was to use something like this circuit and wire it into the AA ipod charger would it work?
Possibly - check the output voltage / current of the cells, and compare it to the rated output of a proper charger for your ipod. If the cells' voltage / current is too high, it might damage the ipod. I think. Possibly.
