Solar panel maxes at 1A, but expected 3.6A?
Each cell was supposed to be 1.8W and .5V, ergo 3.6A by the math. But all put together now (in series) I get 5-5.6 Volts and about 1A max (with meter leads directly on each panel terminal). Voltage seems right, but current seems low. I'd expect somewhere in the area of 10%-15% over/under the estimated max, but this seems very wrong.
I am guessing one panel in it is bad or cracked and I can't see it, and is limiting the whole deal. Does that sound right? Can I test the panels using the volt meter on the in/out leads on each cell, or do the other cells interfere after they're connected?
