Do wind direction and panel inclination affect photovoltaic trackers?

The effect of wind direction and panel inclination is presented. Wind load effects are studied in a computational model. The main photovoltaic tracker components are evaluated under wind effects. Photovoltaic modules are one of the intensively used technologies that provide a renewable energy alternative to electricity generation.

Does sheltering affect wind loading in a PV module array?

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.

Does wind affect photovoltaic modules in a wind tunnel?

The numerical modeling approach in this study was verified using the reference study of Abiola-Ogedengbe (2013), who experimentally investigated the wind effects on a stand-alone photovoltaic module in a wind tunnel.

How are photovoltaic modules tested?

All tests were carried out using rigid models of the photovoltaic modules, that is, the experimental analysis is limited to static wind tunnel testing. A detailed numerical evaluation is performed using the finite element method (FEM) to identify critical structural sections.

Which wind direction is most important in a photovoltaic module?

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.

Do tilt angles and wind directions affect a ground-mounted solar panel?

The wind effects on a ground-mounted solar panel under the influence of the panel tilt angles and wind directions were investigated; both experimentally and numerically. The ground-mounted solar panel was used with tilt angles of 25° and 45° for a Reynolds number of 6.4 × 10 4. Wind directions were varied from 0° to 180° at 30° intervals.
