The Dynamic Loadings of the Solar Panel Mounted on Flat Roof-Top of Buildings by Wind Effects

Abstract:

The dynamic wind loadings of solar panel mounted on flat roof building model were checked with a series of wind tunnel aerodynamic test. In this study the location and wind angle are controlled factors. The results shown that for the panel located near downstream area and its high end is facing the inclined oncoming flow might be the extreme condition, in which the panel is suffered by the highest up-lift forces. Beside the wind pressures coefficients, we have also calculated the co-spectrum of pressures signals at variant faces of panel and roof edges. With the results we found the high fluctuating and extreme wind dynamic loading on panel might come from the well correlation of building roof-top shedding vortices to the panel surface, not the separation shear layers by panel itself.
