Calculation of wind resistance of photovoltaic bracket

First, the calculation principle of wind load of photovoltaic bracket of various standards and the value characteristics of related parameters were compared and analyzed. Second, the shape coefficients of the solar structure under the combination of typical inclination angles and wind directions were derived by performing a rigid model load .

Boundary layer wind tunnel tests were performed to determine wind loads over ground mounted photovoltaic modules, considering two situations: stand-alone and forming an array of panels. Several wind directions and inclinations of the photovoltaic modules were taken into account in order to detect possible wind load combinations that may lead to .

The wind resistance effect of PV panel arrays was investigated in relation to various design parameters. Findings revealed that, in scenarios characterized by relatively low wind velocities, PV arrays with an inclination angle of 35°, no column spacing (0 m), and a row spacing of 3 m exhibited the most favorable wind resistance performance.

In this report, we provide sample calculations for determining wind loads on PV arrays based on ASCE Standard 7-05. We focus on applying the existing codes and standards to the typical residential application of PV arrays mounted parallel to the roof slope and relatively close (3 to 6 inches) to the roof surface.

The flow field around the PV array and the sensitivity of the wind load to the wind direction are studied by numerical simulation method, and the correlation between the wind speed and vorticity field around the panel and the pressure distribution on the panel surface is analyzed (Jubayer and Hangan, 2014, 2016).
