Sun angles depend upon the day, time of day (solar time), and latitude location. Solar declination (δ) is the angle formed between the plane of the equator line drawn from the center of the sun to the center of the earth. This angle varies between ±23.45° on the summer (June 21) and winter solstices (December 21), and is 0° Figure 1. Different
