Earth Geometry
Understanding Earth geometry is important for solar PV systems because the amount of solar energy that can be harvested by a PV system depends on the position of the sun relative to the PV panels. The angle and direction of the sun's rays change throughout the day and throughout the year as the Earth rotates and revolves around the sun, and this affects the amount of energy that can be captured by the PV panels.
