2x2 Solar Panel Array Shadow Limitations
How does a 2x2 series/parallel panel array perform with partial shadows and bypass diodes with a MPPT controller? For example using 30V panels with 3 bypass diodes each and one panel has shade causing...

I believe your assumption is correct. In parallel the shaded panel will basically drop out. In series you lose voltage of the shaded section only. I also believe you lose a bit more than 10v per section because you are pushing through the diode.
Typically I recommend all series or all parallel. The series/parallel would seem to be inferior during shade issues. Unfortunately you are probably up against the controller Voc limit.
