Abstract

The main aim in this research work is to predict the daily global solar radiation (GSR) using the instrument CMP6 Pyranometer at mid-land altitude of Pokhara (28.22°N, 83.32°E, 800m) Nepal. The solar radiation primarily depends on rainfall, temperature, sunshine hour and local weather condition. The regression technique is used on the basis of empirical models and metrological parameters, this empirical model can be used several parameters like temperature, rainfall and sunshine hour. The average global solar radiation (GSR) in Pokhara was 15.90 MJ/m2 /day for the year of 2016. The regression technique was used on the basic of empirical models and metrological parameter and found to be (0.43, 0.20) and (0.11, 0.55) empirical constant are found at modified Angstrom model and gariepy empirical coefficient respectively at the year of 2016. This empirical constant can be predicated to year to come, At the end the measured GSR and predicted GSR are utilized on statistical tools and all the error are very low and within the range likewise the value of R2 are 0.89 and 0.84 in modified Angstrom model and gariepy empirical coefficient are significant.
