Pinball, would you mind sending me specifics about those $0.74/watt panels? Secondly, is the space above the panels or between them. The spacing for the Enphase wire connecting panels is at a fixed distance so I can't put too much room between them on sides or the connect spot would not be below panel.

What would you recommend for spacing? I have lots of room on the big shop roof.

Thanks - and it is good to be back on reading and such.

You can see it in this picture.
They are 4-5” up off the roof and you can walk between them to change out a microinverter.
I had to mount them that way so I could bolt the racks into the rafters.

I still used the portrait cable it just runs from the bottom to the top.

The landscape cable is more money and adds to much voltage drop.

I sent you a message on the panel prices let me know if you don't get it.
