Solar Panel Shadows and Bypass Diodes
The following data was collected from my 3x250W flat mounted solar panels on 1/16/15 in my storage area in the Phoenix area. The graph shows the significant transition as the sun just covers the 3rd r...

This shows an advantage of series panels with bypass diodes and an MPPT controller. For a compatible situation with parallel panels and PWM there would be no power for the batteries prior to the transition.

Don't understand this statement.
When all panels are under full shade, what does parallel versus serially connected panels have to do with power output? Or bypass diodes?
EDIT: Never mind, I get it, finally. That one panel was initially not under full shade. Rather it was under partial shade allowing the bypass diodes to do their thing.
I understand that mppt can be better in full shade.
