Outdoor Study of the Efficiency of Photovoltaic Power Plants with Sun Tracking in a Hot Desert Climate

Using solar tracking PV systems as an alternative to traditional fixed PV installations on inclined surfaces has become a viable option for increasing the electric output of PV silicon technology. This paper examines the performance of power plants with and without sun tracking in real outdoor conditions. The goal is to investigate the effects of climate change on their behavior and efficiency. The findings demonstrate that the dual-axis tracking photovoltaic system generates more energy than the static photovoltaic system (16.72% and 13.66 ^% ) in a clear sky with few clouds and a cloudy day, respectively. The energy yield produced by a two-axis sun tracking system, a one-axis tracking PV system, and a fixed tilt angle on days with little to no cloud cover and a clear sky is 25318.55 kWh-23395.09 kWh, 24766.94 kWh-22707.58 kWh, and 22275.15 kWh-20042,84 Wh, respectively.
