An Experimental Comparison Between Fixed and Single-Axis Tracking Photovoltaic Solar Panel Performance: Zakho City as Case Study

Abstract

The tracking system that uses for PV solar systems has a vital role to improve the energy performance of the solar panel. In the present study, the performance of both the fixed PV solar system and single -axis tracking PV solar system is investigated experimentally. The power for each PV solar panel is 150 W. The performances of the two systems are compared to display the efficient improvement of a single-axis solar tracking (SAST) system with fixed solar (FS) system under the climate conditions in the Zakho/ Kurdistan region/ Iraq. A mechanical tracking device with a controller and linear actuator was designed, and its performance was comprehensively investigated with a PV system. The findings for a sunny day due to the use of a single axis tracking system with a solar panel as compared with those of a fixed panel, that the enhancement in the overall power generation and electrical efficiency are about 28 % and 29 %, respectively.

Solar Panel Efficiency Improvement through Dual-Axis Solar Tracking with Fuzzy Logic and Water Treatment Techniques

“…Similarly, the analysis on fixed and single-axis tracking solar panels by [25] highlight the benefits of tracking systems but fall short of the significant energy yield increase as shown in this research. The method on this research not only confirms the effectiveness of solar tracking as seen in [26], but also significantly advances it in terms of energy output.…”
