The objective of this paper is to predict hourly solar radiation in Faculty of Engineering, Universitas Indonesia, Depok, West Java, Indonesia (106.7942 longitude, -6.4025 latitude) as studied site. The calculation is based on several empirical models and compared to the measured data from BMKG. The comparison of theoretical data and measured data in order to know the influence of solar radiation parameters like solar irradiance condition, angstrom turbidity coefficient, and climate condition used to calculate the solar radiation at studied site. In order to evaluate the performance of solar radiation models, a statistical test was performed by using Mean Bias Error and Root Mean Square Error. The results indicate the best performance of solar radiation models that applicable in Indonesia. Therefore, Benjamin et al. model provides good performances for estimation of the hourly solar radiation.
