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 to 28 m/s, 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, its installation, operation, and maintenance costs compare to other systems using the local electricity tariffs.

“…The standard k-epsilon model is a widely adopted and robust turbulence model known for accurately representing turbulent flow phenomena. The efficacy of this turbulence model has been highlighted in numerous recent research studies examining the impact of wind load and patterns on solar PV panels and arrays, making it a frequent choice for conducting numerical simulations in this context [10,[28][29][30]. By solving the transport equations for turbulent kinetic energy (k) and the dissipation rate of turbulent kinetic energy (ε), the model accurately predicts the flow behaviour.…”

Efficient implementation of clean energy technologies is paramount, with mobile solar PV systems on trailers (MSPTs) emerging as pivotal solutions, particularly in regions with limited power grid access. This endeavour is vital for meeting escalating electricity demands and aligning with the UN Sustainable Development Goal (SDG), aimed at ensuring dependable and sustainable energy provision in developing countries. This study investigates the aerodynamic behaviour of a designed MSPT using numerical simulation and experimental methods, thereby offering optimization potential for MSPT design and enhancing overall performance and reliability. Specifically, the study focuses on the effects of wind velocity and tilt angles on the drag and lift forces, as well as drag and lift coefficients on the panel used in the MSPT system. The overall wind force on the entire MSPT, including nine large solar PV panels, is scrutinised, considering combined wind flow and system geometry effects. The numerical investigations were conducted using ANSYS-Fluent software (version 2022/R2) and experimental testing was performed within the C15-10 Wind Tunnel, utilizing scaled-down models to validate the accuracy of the simulation. The findings from the numerical investigations showed an increased turbulence caused by gaps between panels, resulting in almost 62% higher suction flow velocity and 22% higher suction pressure compared to a single panel. Drag and lift forces on the entire MSPT were approximately 6.7 and 7.8 times greater than those on a single panel with the same 30-degree tilt angle, respectively. The findings revealed that scaling forces on a single panel is insufficient for accurately predicting the aerodynamic forces on the entire MSPT. The insights and the knowledge from this study pave the way for further improvements in mobile solar PV technology.
