Implementation of Klein's Utilizability function for Chennai, Trivandrum and Visakapatnam

摘要

An attempt has been made to find the suitability of Klein's correlation based on data of US locations for three South Indian locations iz., Chennai, Trivandrum and Visakapatnam. Monthly mean daily utilizability by using data and Klein's correlation has been found separately. Values of monthly mean daily utilizability was found by using by using long-term measured data (15 years) of solar radiation on horizontal surface and are termed as data based correlation. Klein's correlation equation has been used for the estimation of monthly mean daily utilizability function for the corresponding locations. In order to find the suitability of Klein's correlation for the estimation of monthly mean daily utilizability, standard and relative standard deviation between the results based on measured data and Klein's correlation equation and compared. Results have shown that Klein's correlation equation can be used for the estimation of monthly mean daily utilizability for any South Indian locations with least error in the absence of available measured solar radiation on horizontal surface.
