Abstract

This research work proposes the coefficient equation of Angstrom type of model for the estimation of global solar radiation in Himalaya Region Kathmandu (Nepal) (Lat. 27.7º, Long. 85.5º and Alt. 1350m) using relative sunshine hour. The model regression coefficients a and b obtained in this research are 0.21 and 0.25 respectively. The performance parameters of the model are: Root Mean Square Error RMSE = 0.071, Mean Bias Error MBE= 0.055 Mean Percentage Error MPE= 0.047 and coefficient of determination R2= 0.71.The solar energy can be utilized effectively throughout the year. The model could be employed in estimating the global solar radiation at the similar geographical location of the country.
