WIND LOADS ON THE ROOF-TOP MOUNTED SOLAR PANELS ARRAY WITH VARIOUS ROOF SLOPES

本文摘要A series of wind tunnel aerodynamic test were conducted to investigate the wind loads on the roof-top mounted solar panels array with four different roof slopes. In this study various location and wind angle are also to be the controlled factors. The results shown that the solar panels will be suffered the maximum wind loading at the small wind azimuth angle, especially which located on the edge region of roof. We have observed that effects of the roof slope could be a significant factor to te solar panel array wind loadings. For the wind direction is normal to the panel which located at the upstream edge and the high-end of panel toward to the approaching flow, the first row panel will be suffered serious lift wind forces. For the following panels, due to the sheltering effects their wind loadings are slightly. It is also found the sheltering effects may last up to four times of upstream panel height. For the variant roof slope the vortex shedding may change deeply by the high-rise ridge of roof, therefore the panel wind loadings will be changed. In the results of the aerodynamics tests which be conducted in this study shown the wind loadings will be rise at the high slope roof cases and the sheltering effects might be reduced in the same time.
