The Azimuth axis: It controls horizontal rotation from east to west, following the sun's daily path. For flat-panel photovoltaic systems, trackers are used to minimize the angle of incidence between the incoming sunlight. . The two most common orientations are: 1. Vertical (Portrait) Orientation: The longer side of the panel runs up and down. This is because as we know, the more surface area that is exposed to direct sunlight, the more output the photovoltaic panel will produce. The greater the perpendicular alignment with the sun's rays, the greater the efficiency. In this way, less light is. .
