Study on the Impact of Climatic and Environmental Factors on the Development and Utilization of Rooftop Solar Energy Resources in Inner Mongolia

摘要

cqvip:Based on the data of 8 solar radiation stations and 119 meteorological stations in Inner Mongolia from 1961 to 2017 as well as the comparative observation of rooftop solar distributed photovoltaic power generation equipment,the impact of climatic and environmental factors on the development and utilization of rooftop solar energy resources was studied.The results show that the main climatic factors affecting rooftop solar power generation were cloud cover,precipitation,relative humidity,visibility,gale,dust weather,temperature and lightning disaster.Except for temperature and lightning disaster,other meteorological elements were negatively correlated with rooftop solar power generation,namely reducing direct radiation.The high temperature in Inner Mongolia in summer could cause the solar cell efficiency to decrease by 40%-60%,while the low temperature in eastern region in winter was not suitable for the development of rooftop solar energy resources.Lightning is the main meteorological disaster affecting the safe operation of photovoltaic systems,and class-2 lightning protection equipment needs to be installed.Photovoltaic power generation equipment should be installed on a roof which is not covered by high buildings and on the windward side of a chimney as much as possible.Areas with heavy dust pollution need to remove dust on the surface of solar panels in time.Snow and ice should be removed timely during snowfall in winter.
