Analysis of global solar radiation in Coimbatore, Tamilnadu

Abstract

Solar energy is extensively considered for satisfying significant part of the energy demand in India and across the world Total daily solar radiation is considered as the most important parameter in the performance prediction of renewable energy systems particularly in sizing photovoltaic power systems agriculture and building design applications In this research the location Coimbatore Tamilnadu is considered for global newlinesolar radiation analysis In order to study the global solar radiation the variables such newlineas global solar radiation average temperature relative humidity wind speed air pressure sunshine hours air pollution were considered using three years data Tools such as mean standard deviation coefficient of variation of coefficient correlation t test multiple regression are used Further based on three years of data, a model is provided to predict the value of global solar radiation for each season To assess whether there exists significant difference in values of variables between the seasons technique of analysis of variance is employed newline
