Advanced Optimization of Photovoltaic Systems Using Response Surface Techniques (RSM)

01.Jan.2025

​This work includes an analysis of experimental results obtained for a 2 kW grid-connected photovoltaic system mounted on an adjustable sun tracker system. A suitable optimization model is exploited to determine the optimal factors' settings that maximize the performance of a photovoltaic system in the lowest productive period in the year concerning solar irradiance (W/m 2). This system was installed at Philadelphia Solar Ltd. in Amman-Jordan. Response surface methodology was the optimization model employed in this study, and it was applied for multiple responses of interest. These responses were the input current and the input voltage; these responses were assumed to be affected by the tilt angle and the azimuth angle. It was found that the optimal tilt angle was 35, and the optimal azimuth angle was 0. These installation settings ensured their validity when used in periods with the worst environmental conditions in Jordan. The efficiency of the photovoltaic station can be increased by 10% in this period by operating the station using these settings, where the current value is 7.9197 A and the voltage value is 225.451 V.​
