In this paper, the flow characteristics around the solar photovoltaic array are numerically simulated by the CFD method, and the influence of panel array arrangement on the wind resistance of floating solar photovoltaic array is studied. The major findings are presented below:
The wind load on the photovoltaic panel array is sensitive to wind speed, wind direction, turbulence intensity, and the parameters of the solar photovoltaic panel structure. Many researchers have carried out experimental and numerical simulation analyses on the wind load of photovoltaic panel arrays. Table 1.
tovoltaic (PV) solar systems in typical applications, when mounted parallel to roofs.2 SCOPEThis document applies to the testing of the structural strength performance of photo voltaic solar systems to resist simulated wind loads when installed on residential roofs, where the panels are installed parallel to the roof surface
Many researchers have carried out experimental and numerical simulation analyses on the wind load of photovoltaic panel arrays. Table 1. Features of different offshore floating photovoltaics. The boundary-layer wind tunnels (BLWTs) are a common physical experiment method used in the study of photovoltaic wind load.
In addition, most of the research focuses on the structural parameters of photovoltaic panel inclination, photovoltaic panel spacing, and installation height.
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.
Determining Wind and Snow Loads for Solar Panels
1) Select wind direction for wind loads to be evaluated. 2) Two up-wind sectors extending 45 degrees from either side of the chosen wind direction are the markers. 3) Use Section 1609.4.2 and Section 1609.4.3 to determine the exposure in those sectors. 4) The exposure with the highest wind loads is chosen for that wind direction.
