Jubayer and Hangan (2014) carried out 3D Reynolds-Averaged Navier–Stokes (RANS) simulations to study the wind loading over a ground mounted solar photovoltaic (PV) panel system with a 25 ° tilt angle. They found that in terms of forces and overturning moments, 45 °, 135 ° and 180 ° represents the critical wind directions.
The wind load is especially important for floating photovoltaic systems. Fig. 2, a floating photovoltaic system is above the sea or a lake. A floating body supports the solar panels by the buoyancy force, which is balanced with the weights of the solar panel and itself.
Different roof types cause different flow patterns around PV panels, thus change the flow mechanism exerted on PV panels. In this study, the effects of roof types, heights and the PV array layouts on the net wind loads of the PV panel is investigated.
For the stand-alone case, the most influential wind flow directions correspond to oblique directions for local pressures and along wind direction for overall forces. For the case of the photovoltaic module array, it is observed that the wind loading over the leading panels is decisive for the design.
This study investigated the aerodynamic structure surrounding the roof-mounted PV array and the net mean Cp on PV panels by means of the RANS approach, and mainly analyzing the mean wind loads of panels. The simulated results of downstream panels deviate from the wind tunnel tests apparently due to the limitation of RANS.
Moreover, it was found that in a PV module array the effect of sheltering on the inner PV modules decreases starting from the second downwind row. Wind tunnel tests (with a model scale of 1:20) performed by Pfahl et al. (2011) demonstrated that the aspect ratio of the panel also affects the wind loading components.
