My interpretation is that since voltage drops off in the shade, a 12v panel is doomed. But a 24v one can still get enough volts to charge with.
I think you're wrong, but let other fellow nerds comment in more details ;)...
Nerd here. When a PWM 12v loses voltage from 21 volts (12v panel) it still has plenty to be over 13v so amps don't suffer. MPPT (37v "24v" panel) makes its amps from voltage so it does suffer if voltage goes down.
You can't make something out of nothing and solar is pretty much of an all or nothing deal. You can get an amp or two in the shade instead of your proper x amps, but so what? 1 amp for 8 hours is 8 AH. Whoopee do.
