Study On Atmospheric Environment And Its Impact On Efficient Utilization Of Solar Energy

Atmospheric environment is closely related to the survival and development of human beings. In recent years with the rapid development of society, the excessive consumption of fossil fuels and atmospheric has emerged, at the same time clean energy, the alternative energy like solar energy and wind energy got the large-scale development. Because of the atmospheric environment especially the atmospheric particulate matter and subside in solar module and dust weather result in the drop of solar ratio, so the study of solar dust weather and atmospheric particulate matter has the influence on the application of solar energy.Firstly this paper is acquainted with the dust weather of some Inner Mongolia region geographical location in north-west district, and data acquisition of particulate matter in monitor stations, modeling calculation and analysis of diffusion factors, In Inner Mongolia industrial university key laboratory for wind and solar energy province department of project complete the collection of dust that natural fall on the five photovoltaic panel surface, and photovoltaic/solar thermal whether or not have dust covered parallel experiment.Through the date collection of fine particulate matter in some region of Inner Mongolia environment monitor stations and modeling calculation, this paper identified that the fine particle PM2.5is the primary particulate matter in Inner Mongolia atmospheric environment, wind, atmospheric stability and city building effect the diffusion of atmospheric particulate matter.In the laboratory we collect the dust that natural fall on the photovoltaic panels surface, and calculate the per square meter the dust possess1.64-2g/m2.Through the particle size analysis we get the particle size distribution range of dust between20-30nm, where the25nm have the majority distribution.In this paper at winter sunny noon through the clean panel and dust covered panel parallel experiment, we got the conclusion that photovoltaic panels output power decreased6%～7%when take the collected dust sampling2g uniformly coated on the photovoltaic surface, and the basic meteorological factors are the total radiation intensity880-900w/m2,ambient temperature at3℃～4℃,furthermore the wind speed range from0～1m/s.In this paper through the solar thermal parallel experiment, at winter sunny noon basic meteorological factors are the direct radiation intensity500-600W/m2,ambient temperature are4～5℃,moreover the wind speed range of0.5-1.5m/s,the natural atmospheric environment deposition that after18days the solar thermal module compares the clean module that the test results are that at lOL/h condition, the difference thermal efficiency between both solar thermal module are5%,at20L/h condition, the difference thermal efficiency between both solar thermal module is15%, at40L/h condition,the difference thermal efficiency is20%.
