The aerodynamic research of solar panel assemblies and the determination of wind load are presented in this chapter. The task is solved in the first phase using a 1:1 computer simulation of the wind flow around the suggested rectangular assembly using the FLUENT ANSYS programme, followed by experimental measurements in the wind tunnel with a boundary layer (BLWT) in Bratislava. The solution's goal was to figure out the maximum pressure and suction wind loads on the top and bottom surfaces of panels. The greatest local pressure in each panel row as maximum values from all wind directions is represented by the resulting net pressure coefficient. The experimentally determined net pressure coefficient values were compared to computer simulations and processes described in STN EN 1991-1-4. It is clear that the inner panels are loaded far less than the norm requires. The panels on the side of the assembly or along the aisle's edge are loaded substantially higher than the norm allows. In addition, frontal panels are less wind-stressed than the norm specifies.
