HACKED!!!!!!!!!!!!
I found a 7805 voltage regulator that lowers 6-18 VOLTS to 5 VOLTS, Next I unsoldered it from the UPS pcb, soldered it correctly to 2 solar panels I had in my collection, and then to a USB port!

I have to say that I'm not sure where you can salvage solar cells/panels, But you can always put a lot of solar panels in parallel to have more amps... You can use these

Solar panels on some (obviously solar-powered and sometime also hand-cranked) radios, and solar garden
lights are where I usually see them being salvaged. Sometimes the
batteries on the garden lights will fade, but the panels are still good
(and the LEDs). And I have seen some really small ones (only one very small panel) on some
calculators.
