PV-Tracker-Angle

What influence has the layout of the solar site on the positioning of the PV modules to the sun at a specific location? One can enter the gps-coordinates from ZIMMERMANN PV-Tracker commissioning preparation form to analyse tracking behaviors for different site conditions (azimuth angles, row pitch, panel witdh & maximum turning angle) during the year. The displayed information shows the tracker angle to the sun and and supports conclusions on optimal design for the power plant.
