Abstract
When PV power stations operate under actual outdoor conditions,due to different climatic conditions in different regions,the operation of PV power stations varies greatly.Meteorological factors such as strong sunlight,significant changes in ambient temperature and humidity,acid rain erosion,wind and sand erosion,etc.will inevitably affect the power generation performance of PV power generation equipment,accelerate its aging degree,and ultimately affect the power generation efficiency and lifespan of PV power stations.Based on the existing classification of climate zones in China,this paper analyzes the climate characteristics of different climate zones,and then compares the operating data of PV power stations in different climate zones,analyzing the impact of different meteorological factors on the power generation performance and differences in power generation capacity of PV power stations.The research results show that due to significant differences in meteorological factors such as endowment of solar energy resources,ambient temperature in different climate zones,the impact on the electrical performance parameters such as working voltage,working current,and output power of PV power stations varies in each climate zone.Therefore,when constructing PV power stations,equipment selection and optimization design schemes need to be combined with the climate characteristics of different climate zones to ensure that the PV power station can achieve the best operating effect after operation.关键词
