    I read over and over about the difference between wiring 2 solar panels in
    series and in parallel and inevitably the examples are for identical cells
    where you add voltages or add currents. Straightforward enough. My question
    is what do you get when adding dissimilar panels. If you have a panel with
    1 Volt and 2 Amps in series with a panel at 2 Volts and 1 Amp you get 3
    Volts, but do you get 1 Amp? Or 2 Amps? Or no Amps because the 2 Amp panel
    puts too much current through the smaller panel and burns it out?

    Is the panel damaged if you drive current through it at higher than it's
    rated output, as in my sample case here of a 2 Amp and a 1 Amp panel in

    If you put the same panels in parallel do you get 2 Volts at 2 Amps? 2
    Volts at 1 Amp? Something between 1 and 2 Volts? Between 1 and 2 Amps?

  2. Add the volts and take the lowest current.
