Abstract

The experimental results on global solar radiation in some locations in Nepal measured by calibrated pyranometer at Jumla(29.27N to 82.18E, 2514.0m), Dang (28.70N, 82.18E, 603.0m) and Nepalgunj (28.05N, 81.62E, 150.0m) since 2011. The influence of different meteorological as well as physical parameters to the intensity of global solar radiation was analyzed. This research highlighted fluctuation of the measured value of global solar radiation with local weather condition. Measured global solar radiation data shows that there is about 7.5% per km increase in Jumla in comparision with Dang and Nepalgunj. This result conformed that there is strong correlation found in between altitude and global solar radiation. In addition the GSR varies with environmental pollution and local weather condition.
