      In general, the Sun declination angle, δ, is defined to be that angle made between a ray of the Sun, when extended to the center of the earth, O, and the equatorial plane. We take δ to be positively oriented whenever the Sun’s rays reach O by passing through the Northern hemisphere.

      The collector angle (θ) between the sun and normal to the surface is cos(θ) =sin(β1)cos(β2 ) +cos(β1)sin(β2 )cos(α1 −α2) (11) where α2 is the azimuth angle normal to the collector surface, and β2 is the tilt angle from the ground. If θ is greater than 90°, then the sun is …

      The altitude angle (β) is determined by measuring the angle between the sun and the local horizon directly be-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.
