Wind load analysis and cost assessment of a dual-axis stand-alone photovoltaic structure

Abstract

This study investigated the effect of wind load on the structural stability of a dual axis tracking system developed at the Botswana International University of Science and Technology (BIUST). Through simulations, the study explored wind speed variations, from 8 m s−1 to 28 m s−1, while simultaneously adjusting the azimuth and elevation angles of the structure. Utilizing computational methods and numerical simulations, the study models wind flow interactions with the dual-axis tracker system. This knowledge can be used to improve the system’s design, ensure safety, and optimize energy production and efficiency. The findings of this study contribute to the field of renewable energy, specifically in the context of solar power generation using dual-axis tracker systems. The results offer valuable insights into the wind load behavior, structural response, and energy consumption, facilitating the development of more robust and efficient tracker designs. Furthermore, the study used the levelized cost of electricity (LCOE) to investigate the cost effectiveness of the solar system. The aim was to establish how the energy production of the system, the installation, operation, and maintenance costs compare to other systems using the local electricity tariffs.
