Effect of photovoltaic panel on the distribution of the external pressure coefficient for flat roofs

Key Points

The presence of photovoltaic panels alters the distribution of external pressure coefficients on flat roofs.
Values of external pressure coefficients were obtained through simulations using Computational Fluid Dynamics (CFD).
The study identifies significant gaps in existing wind standards regarding data on photovoltaic panel impact.
Results emphasize the need for updated wind standards to include considerations for photovoltaic systems.

Abstract

The article presents an assessment of the impact of photovoltaic panels on the distribution of wind pressure coefficients on a flat roof. It highlights the lack of data on this issue in the currently applicable wind standards. The analysis was conducted using AxisVM software, employing a tool based on Computational Fluid Dynamics (CFD) for simulating a wind tunnel. The external pressure coefficient values were provided for the parameterised case
