摘要
This study experimentally determines the wind loads on a stand-alone solar array (length-to-width ratio of 0.19; 1/10-scale commercial modules). The freestream velocity in a uniform flow is 14.5 +/- 0.1 m/s, and the turbulence intensity is 0.3%. The angle of tilt ranges from 10 degrees to 80 degrees and the wind is incident at angle of 0 degrees-180 degrees. Mean surface pressure measurements on the upper and the lower surface of the inclined solar panels are used to calculate the lift coefficient. For the angle of incidence of 0 degrees-60 degrees for the wind, the variation in the lift coefficient with the angle of tilt is U-shaped. The formation of a strong windward corner vortex results in greater lift force on the right half of the inclined plate for the angle of incidence of 30 degrees-45 degrees for the wind.
