The only significant shadow object is the AC and you layout clusters the panels around that item. I think you can do better.
Mount 2 panels lengthwise along the front vent. They will slope to the front with very little AC shadow. Perhaps mount them several inches high and hence the vent can be opened some with no shadow. See
my son's install for an example.
Mount 2 more panels length wise in the rear. One in front of the ladder and one in front of the DS rear vent, or maybe over this vent and just in front of the skylight. Mount them above the sewer vent, etc and slope them to the outside. Again no shadows when the vents are closed.
If closed vents are a problem then raise the panels enough to allow you to open the vents some. Depending upon your orientation they can be opened more at mid day.
If your power vent has a high rain cover remove it.
If you plan to remove the panels when you sell the unit I would mount the PS front panel over the batwing and find an alternate location for a second TV antenna. Maybe one that doesn't crank up located next to the AC. Connect the coax into the existing coax on the roof.
