Experimental evaluation the effect of tilt angle on solar panel performance in Baghdad Available to Purchase

With the increasing need for economically viable, environmentally friendly, and sustainable power sources. Solar photovoltaic (PV) systems are becoming more popular. The efficiency of a photovoltaic (PV) system is greatly influenced by its tilt angle and orientation. Few scientists investigated the impact of tilt angles on photovoltaic efficiency to produce electricity under the Baghdad climate. An experimental investigation was conducted to detect the difference in PV efficiency and electrical characteristics at various tilt angles in Baghdad circumstances. In this study, the solar PV plant consisting of two PV panels was used. The efficiency of the solar PV plant was evaluated during the months of June, July, August, and November under tilt angles namely (15°, 33°, 45°and 55°). Results show that the best experimental inclination angle for PV-panels during summer season is 15° degree for the months June, July, August, and November. This allows for higher power developed and improved PV-panels operating efficiency. During the July month, the PV-array efficiency was found in the range of 10 to 12% for different inclination angles. The experimental findings reveal that the acceptable tilt angle for Baghdad climate is 15°. This angle will capture the most energy from the sun and thus improve its performance.
