  This experiment takes the roef Gridconnected PV System as the experimental platform of NO1 Laboratory Building, Beijing University of Civil Engineering and Architecture.By setting the control experiments of A,B two groups to monitor data in March 2015.The result shows that the output of B than A is relatively increased by 8.1% after cleaning.So its very important to study the effect of dust deposition on the power generation of PV system in the increasingly serious environmental situation.
