I guess my thinking that multiple panels wired in parallel provides better protection against total system voltage sag from one or more panels being shaded assumes that a shaded panel's internal resistance increases.
Is my assumption true ... does a solar panel's internal resistance increase or decrease as it becomes more and more shaded?
P.S. I guess that the SolarMagic solution for isolating a shaded solar panel from the rest of the panels in an array didn't work out?: https://en.wikipedia.org/wiki/SolarMagic
