| Abstract: |
| Wind loads play a major role in designing of structural systems for roof-mounted photovoltaic panels.The detached eddy simulation method is employed in this study.Computational wind engineering method has been performed to evaluate wind loads on photovoltaic panels mounted on the roof.The simulation results have been compared and validated with a wind tunnel experimental measurements.The main parameters affected wind loads acting on photovoltaic array panels,such as panel tilt angles,the installation locations on the roof,distance between arrays,and wind directions,were considered.The numerical results showed that the mean values of the uplift wind loads increase with increasing in tilt angle from 15° to 40°.The numerical data demonstrated that wind loads on the photovoltaic panel were substantially affected by the vortices generated by building roof edges.The study also showed that sheltering effect caused by upwind photovoltaic panels reduced the wind loads on the adjacent panels when they were arranged in tandem.The proposed numerical method and the calculation results could provide an important reference for the design of photovoltaic array supporting systems,which are mounted on the roof,and the building structures. |
