We didn't DIY. Our installer was happy to put the panels wherever we wanted.

Our roof is an even East/West split. So one side powers our morning and the other side our afternoon.

It's really interesting that you still get a smooth production graph with east/west, I wasn't sure what that would look like.

We have east and south and our peak production is when the sun is at the south-east, in the middle of the two faces. The east face production drops off from there on out until it's a fraction of what the south face is generating.
