I have 10 used PowerFree 100 watt panels.
(Pmax) 100w (+0/3%)
(Vmp) 17.8V
(Imp) 5.62A
(Voc) 21.6V
Isc 5.97A
9 of them read roughly 22.0 volts and 6.5 amps when metered individually, on the ground, in full sunlight, on a 20 degree F. day.
One of them reads 11.08 volts but still has the 6.5 amps.
Could this be a result of bad Diodes in the panel's wiring box on the back of the panel? I can find nothing else wrong with the panel albeit I didn't look it over with a magnifying glass.
