As an important constituent part of the particles in the atmospheric environment of desert, sand affects the solar power by falling on the solar panels nearby by means of suspension and saltation. The present study applied the sieving method to conduct a particle size analysis of the surface sand particles with particle size less than 1mm in the solar power station in the Kubuqi Desert. As indicated by the results, the particle size distribution of sand accords with the exponential distribution law; the particle size of the ground sand is larger than that of the sand in the sand collectors and its sorting is poorer as compared with that of the sand in the sand collectors, which is caused by external factors such as the wind etc.; there is a good correlation between the particle size proportions of the sand in the sand collectors and the ground sand; the weight of sand in the sand collectors follows the law of a power function that decreases progressively as the height increases; the higher the solar panel, the less it will be affected by the sedimentation of the ground sand. The above research findings will provide certain theoretical basis for exploring the influences of sand on solar power stations in the desert.
