OP: For example, if a panel is ~21 volts, 3 in series, each 11 amps, rated at 200 watts?~ 22V max, normally around 18V under load.
OP did not indicate the Voltage of each sub string (two sub strings connected in series to form one pane, l.E 36-CELL PANEL, each sub string has 18 cells with one bypass for each substring) of each panel, as you can see it has two bypass diode for each substring.
