Solar on Roof -- How You Park-Series vs Parallel ? UPDATE

I wonder if the large differences in amps per panel wrt to total amps I reported in the OP was more from the sun being so low mid-day.

The minor angle differences of flatness on the roof would be bigger wrt to the sun's angle than if the sun were higher. Perhaps with the sun higher, the amps differences would be less in proportion to the total amps, and become trivial?
