INFLUENCE OF ATMOSPHERIC AEROSOLS ON THE AMOUNT OF SOLAR ENERGY REACHING THE EARTH’S SURFACE IN THE SOUTHERN PART OF WARSAW

Abstract

The efficiency of photovoltaic installations depends on a number of factors. Aerosols cansignificantly influence the available resources of solar energy and thus the effectiveness of solarpanel performance. The work was an attempt to assess the influence of atmospheric aerosols onthe transmission of solar radiation in a selected region of Warsaw. The results of measurementsof specific meteorological elements and the concentration of contaminants come from themeteorological station of the Warsaw University of Life Sciences in the years 2014-2019. Theanalysis of correlation and the MLP model path were used to carry out the analysis. The obtainedresults and relationships show that there is an influence of air contaminant concentrations onthe intensity of solar radiation and insolation. High variability of the given parameters was alsorevealed, depending on the range of horizontal visibility as well as relative air humidity. The valueof the correlation coefficient r=0.80 and comparison of the intensity of measured and predictedsolar radiation of the analysed parameters make it possible to claim that the developed MLP modelfacilitates good prediction of the intensity of solar radiation based on the implemented inputdata. The analysis of the sensitivity of the model revealed that the air temperature has the greatestinfluence on the value of solar radiation intensity, and as far as air contaminants are concerned, theconcentration of particulate matter PM10 has a greatest influence on lowering its value.
