neath the sun. The solar azimuth angle (Φs) is the angle formed between the current east/west position of the sun from true south, where true south is used as the ref-erence in the northern hemisphere and has a 0° relative angle. A positive azimuth angle is before solar noon and a negative angle is after solar noon; remember that solar
