A primary reason for wind induced failure of a solar panel and its support structure is the imperfect method for its wind resistance design,especially,the wind load distribution model.Through a rigid model pressure test in a wind tunnel to obtain the distribution law of shape coefficients of the solar panel surface and the whole wind load on the solar panel,a four-corner-distribution model and an eccentric moment model considering effects of both inclination and wind induced moments were proposed.Three wind load models including uniform distribution model,trapezoidal distribution one and eccentric moment one were given in term of structural features of a solar panel.Deficiencies and improvement measures of wind load models used currently in the solar panel design were analyzed.Through comparing the three wind load models mensioned above,a guidance was provided for correctly choosing wind load in the anti-wind design of solar panels.
