Numerical Simulation of a Ground-Supported Solar Panel PV Array Subjected to Periodic Flow

Abstract

Detailed numerical modeling and research were conducted to assess the influence of wind loads on various solar arrays using commercial software such as Ansys. A large amount of damage has been recorded from solar arrays and mounting frames worldwide owing to strong winds. This paper exemplifies the analysis of displacement and stresses of the structure due to strong wind flow and wind load around the solar panel. Since the solar panels are located in the same panel array at the same spacing, we assume that periodic flow conditions can be applied in the flow direction. The model displays a flow field with a free flow velocity of 10 m/s , 25 m/s, and 50 m/s and calculates the resulting structural stresses and displacements. This model uses two other studies. Initially, Turbulent Flow, a k? physical interface, is used to resolve turbulence around the solar panel. The other uses the Solid Structure physical interface to resolve structural stresses and displacements. Fluid Structure Interaction, Fixed Geometry Multiple physical coupling features are used to connect the boundary load of a fluid flow to a solid region in the fluid region. It corresponds to unidirectional fluid structure interaction analysis..
