The morning and afternoon sides of this curve still contain slight notches from the dormer, but the morning notch is partly caused by the neighbor's roof, because the sun rises quite far to the south. The afternoon notch is partly caused by the pine trees by the neighbor's garage, but the sun is far enough south that the maple tree is no longer a contributor. Most noticeable is that the flat-topping effect appears to have been eliminated, but now there is a differently-shaped notch caused by large pine trees in the neighbor's backyard (close to his house), which shade the west side of my roof from about 11:30am until 2pm.

• The red lines in this image show the actual energy generated during a cloudless day in late autumn.
• The dashed yellow lines (from left to right) indicate 8:30am (when the shadow of the dormer and/or neighbor's roof left the panels on the west side) and noon (when the sun was due south).
• The black curve represents my theoretical estimate of the energy that could have been generated under ideal, unshaded conditions.

Summary:

Condition	Energy	Percent of Theoretical
Theoretical	17.3 kWh	100%
Actual	14.8 kWh	85.6%
Dormer Shading (morn + eve)	0.6 kWh	3.7%
Pine Tree Shading (11am-4pm)	1.9 kWh	10.7%
Flat-top Effect	0.0 kWh	0.0%
