The Shortest and Longest Days of the Year, December 21st & Jun 21st

The solar panel placement below demonstrates the path of the sun and shadows in South Park on the shortest and longest days of the year.  The house will block the sun for the last 22 minutes of so before the sun sets on the winter solstice.  During the summer months, the sun sets north of the barn, but without a tracking mechanism to allow the panels to follow the sun, they would not be generating once the sun is no longer shining on the panels.

The video starts at sunrise (0724) and ends at sunset (1638), and then rewinds back to sunrise.
