I was looking to build a solar usb charger for all of our junk while we're out n about... Shopping about I found auctions for 3*6 panels, I figured a decent buy for about $1 each...
Average Power (Watts): 1.8 Wp
Average Current (Amps): 3.6 Imax
Average Voltage (Volts): 0.5 Vmax
The average power seems to be about .3 in the sunlight, if I can get something that'd take down to .2 it'd be ideal since I work in an office. They have decent efficiency, but for smaller projects, like the one I'm thinking, I need to step up the voltage, and can sacrifice the amps for it...
