The experiments were carried out at the panel inclination of 25 degrees and 45 degrees, dimensionless panel spacing in tandem of 0.5 and 1, and the wind directions of the incoming flow were varied from 0 degrees to 180 degrees at 30 degrees intervals. A constant temperature anemometer was used to measure the velocity and turbulence intensities, and a pressure scanner system measured static pressures. The results indicated that the net pressure coefficients of the solar panels were increased with the panel inclination angle and spacing between solar panels, and the maximum wind loads were obtained on the first windward panel. It was also observed that in terms of maximum uplift and drag, 180 degrees and 0 degrees was found to be the critical wind direction, respectively. In contrast, in terms of overturning moments, 30 degrees and 150 degrees were the critical wind directions.eninfo:eu-repo/semantics/closedAccessAerodinamics loadsAnemometersReynolds numberSolar concentratorsWind stressWind tunnelsConstant-temperature anemometersInclination anglesNet pressure coefficientsOverturning momentSolar panel arraysStatic pressureTurbulence intensityWind directionsSolar cell arraysEngineeringWind loadSolar panel arraysPanel spacingTurbulent flowsInclinaion angleWind loadsScaling parametersCoefficientsHeliostatsSimulationRoofsArticle0005244352000012-s2.0-850831880753380339623417Engineering, MechanicalStructural Dynamics; Roofs; Non-Gaussian
