On the other hand, if there are nearby walls and trees, I need to know
the angle of the sun off the horizon and the sun's path, the height of
the wall and distance to my patch of ground, and a bunch of trig to
figure out how much sun the area gets.
Does anyone know of a resource to help me make these calculations?
