Figure 2.1a shows the monthly period variation of solar altitude angle in Tunisia made along the year according to the calculations using the MATLAB® program. The maximum value of the local solar altitude angle, where in Tunisia, reached 75° in summer season (June 21) and a minimum value to 30° in winter season (December 22). Figure 2.1b shows the period variation of solar azimuth angle in Tunisia for every month made along the year according to the calculations using the MATLAB software program. The local largest solar azimuth angle occurs as 90° (June 21) and the smallest solar azimuth angle occurs as 62° (December 22).

The zenith is the vertical line, perpendicular to the horizontal surface. Hence, the zenith angle θz is the angle between the zenith and the line to the sun's rays. Another important geometric term is the solar altitude angle αs—the angle between the horizontal line and the line to the sun. This is the complement of the zenith angle, as shown in the Figure 2.3. The solar azimuth angle in Figure 2.3 is the same as the surface azimuth angle γs. If one were to project the ray of the sun vertically on a horizontal surface and measure the angle that it makes with the south, this will provide the solar azimuth angle.

Solar azimuth (angle) The projected angle between a straight line from the apparent position of the sun to the point of observation and due north. The angle is measured clockwise using the projections on the local horizontal plane, 0–360°.

The spacing between two rows in a multi-row PV panel array for eliminating the shadow due to front row module on to the back row module can be found out by using basic trigonometry. Solar azimuth angle and solar altitude angle of the place under consideration can be obtained from the solar chart.
