In this video I show a project I am working on, turning cheap solar lights into a full 12 volt Solar panel!
Power output of this set is about:
Open circuit voltage: 19.8-20 volts DC
Current at full sun: ~20-40mAh
Battery pack specs:
7 x 1.2volt AAA @ 300mAh = 8.4volts @ 300mAh
Batteries get a full charge in about 4-6 hours from the homebuilt panel. There is a diode in the panel circuit to stop the batteries from draining back to the panels that I salvaged from a cheapie speaker system.
