Another question, I have an older 17watt solar panel that I'd like to add to the 2 80wt panels. How do I do it? Any negatives to doing it? Thanks, Larry

    First question - - what are the actual measured open circuit voltage in full sunlight, preferably with them side by side? Is for example, the small one putting out 17 volts and the bigger ones 21 volts? Or do they all put out 21 volts?
