Posted - Feb 22 2012 : 9:25:18 PM I am trying to construct a phone or electronic device charger using a small solar panel as the power source. I am a novice at this sort of thing and am wondering if anyone can give me some info on the components i will require in the circuit. The out put i am looking for is 5.0V=0.7A. Maybe even a schematic of something similar?

Posted - Feb 23 2012 : 2:23:23 PM The easiest thing to do would be to just connect up enough panels in series to generate 5V. The device you are wanting to charge probably already has a charging circuit built in and just wants about 5V that it would get from a USB port.
More complicated would be to use a DC-DC converter so that any voltage output by the solar panel would be converted to 5V. For example (found via Googling for "solar charge circuit 5V"): http://www.trevorshp.com/creations/solarcharger.htm
