An Analytical Study into the Impact of Wind Load on the Stability and Robustness of Solar Panel Support Structures

Abstract

Renewable energy sources, including wind, hydro, solar, and tidal power, are experiencing a growing global focus. Given the escalating ubiquity of expansive solar arrays, it is crucial to prioritize the dependability and structural soundness of the supporting frameworks for solar panels. The current study examined the effects of different wind loads on the lateral stability of frames of sup- port made for solar panels using the finite element approach. The research examined wind speeds ranging from 72 to 144 kmph, and the calculation of wind forces was performed using mathematical approaches. The results of our investigation demonstrate that wind loads significantly influence the structural soundness of solar panels, resulting in noticeable enhancements in total deformation and maximum equivalent stresses. The investigation findings indicate that the points of intersection within the supporting structure of the solar panel saw the highest levels of stress equivalence. Moreover, it was observed that the structural deformation exhibited greater prominence in the central and foundational areas. The research investigation has yielded valuable insights into the spatial patterns of stress and defor- mation, two critical parameters that play a pivotal role in the design, durability, and efficiency of support systems for photovoltaic modules. The implications of these findings carry considerable weight regarding the future progress of large-scale solar arrays, hence requiring further investigation to optimize the design and functionality of the supporting frameworks.
