• Useful to study latitude (not much difference) vs time of day (lots of differentce, as this difference is determined by air mass. Think of space: in space around the earth, insolation would be constant.

• Dual axis trackers improve energy gain by 40% [1]. Is that over fixed mount or seasonal change mount?
• Bifacial panels add 14-40% more energy gain, and tracking adds about 40% [2]
