My shed has one side of its roof facing east, and the other west. When the sun rises and sets, this will mean that half of my panels are in sun and the other half are not.
What I have done is put a schottky rectifier between the two pairs of panels so the side in sun is not dragged down by the one in shade.
This is my shed here with 4 of the 8 panels visible. Each side has 4 100 watt panels in parallel.

All of the negatives of the panels are linked together. The 4 positives of the left side go into the left side of the diode and the right 4 positives go into the right side. The middle pin of the rectifier goes to the controller.

So, is this a good setup and is the diode needed? The panels themselves have no blocking diodes, only bypass diodes.
