Performance study of global solar radiation estimate's models for Uttar Pradesh

摘要

This work studies the performance of global solar radiation estimates correlation by using some statistical parameters, which enables the model tester to determine whether or not a model's predictions are statistically significant at a particular confidence level. Global solar radiation and the bright sunshine hour data have been analyzed to find the regression constants of the modified Angstrom linear correlation. The proposed correlation with regression constants a=0.407 gives the better results.
