Wind load is one of the main concerns in designing the support structures of solar panels.Currently,there is no unified standard for determining wind loads on double-slope solar panels.In or-der to study the shielding effect of double-slope solar panel arrays,the Reynolds-averaged Navier-Stokes(RANS)method and the shear stress transfer(SST)k-ω turbulence model were employed to in-vestigate the influences of incoming wind direction and inclination angle of the support on the wind loads of solar panels.Based on the analysis of shielding effect,the shape coefficient for the solar panel arrays was suggested,and compared with recommended values specified in the standards of three countries.The results showed that double-slope solar panel arrays exhibit significant shielding effects.The unfavorable wind directions for the shape coefficient of solar panels are 0° and 15°,and the maximum wind suction occurs at the leading edge or the corner of leeward solar panel.As the in-clination angle of the support increases,the overall shape coefficient and the maximum wind suction increase significantly.The shape coefficient of leeward solar panel is higher than the recommended value for an open double-slope roof given in Chinese code.
