Abstract

This study is focused on the performance of four single and multiple-parameters models for the estimation of global solar radiation in Midwestern, Jumla Nepal located at latitude of 29.270N, longitude of 82.190E and at an elevation of 2,347 m from mean sea level. The study is carried for year 2011 and 2012. The performance of models was evaluated on the basis of Root Mean Square Error RMSE, Mean Bias Error MBE, Mean Percentage error PME and coefficient of determination (R2). Based on the statistical error indices obtained, Swarthman- Ogunide model was found to perform best in terms of accuracy with least RMSE value and highest coefficient of determination, R2 value for the location. Thus, the Swarthman - Ogunide model is suitable for estimating global solar radiation in the Midwestern, Jumla Nepal and other locations with similar geographical and climatic conditions. Also, from regression technique and statistical analysis it is found that sunshine based modified Angstrom-Prescott model showed the best results in terms of empirical coefficients a and b are 0.41, 0.34 and 0.35, 0.46 respectively.
