摘　　要：对广州的中山大学南校区（S）、中山大学东校区（M）、凤凰城（P）3个地方的灰尘情况进行观察分析。分析手段主要是对放置在户外一段时间的玻璃的透过率进行测试，然后采用简化的模型计算玻璃上的灰尘对中山大学太阳能系统研究所天台上的CIGS光伏电站的发电量的影响。从分析可以看出，灰尘主要降低玻璃450—880nm波长的透过率，测试时间段内透过率降低1．3％～4．O％。通过计算得到月发电量降低高达2．61kWh／kWp。The effects of air cleanliness on the PV system performance were mainly discussed in three places of Phoenix （P）, south campus （S） and east campus （M） of Sun Yat-sen University. The dust on the module was tested by testing the transmittance of the 1 # and 2 # glass from two different factories. The exposure period of the glass was three months or one moth. Additionalyy, the effect of the dust on the electrical output was calculated by using Wei Zhou＇ s model ac- cording to the test results. The results show that the dust on the module significantly affects the electrical output of the PV system with the absorbing area 12.04m2. The monthly effect is high to 2.61kWh/kWp. From the analysis, it is an incentive action to clean the module aperiodicalyy. The dust deposition is related to the location and weather condition.
