Hey /diy/

I have a question: A solar panel I have has a 5 watt output but only releases .65 volts and over 7 amps. If I hooked it up it a converter that has a 5 volt input, would the converter still work? I ask this because with 5 watts you could have a 5 volt 1 amp output. I apologize if seems like im making no sense.

no, you need to be in the input voltage range for the converter

Why did you make two threads on the same topic?

Actually, OP needs some more. As pic related shows, the rated voltage is only reached at optimum conditions. 0.35-0.4V would be a more realistic approach. Therefore, at least 14 of such cells need to be connected in series.
A better approach would be IMHO to buy a cheap "12V" (actually more like 17V max) solar panel with 10-20W, which are quite cheap nowadays. Then, simply connect an MPPT tracker-like device to it, dial the input voltage to min 15V and the output voltage to max 5.2V, and you're set. I own this very device, and it works just excellent.
