Study on the estimation of solar radiation: Case study: Jakarta, Indonesia

The aim of this study is to compare the performance of solar radiation models from the literature to estimate the hourly and monthly intensities of solar radiation in Jakarta, Indonesia (−6.12 latitude, 106.77 longitude). The estimation of hourly solar radiation calculated through three empirical models such as Liu and Jordan, Campbell and Norman, Tanaka et al. Then the monthly solar radiation also calculated through three empirical models such as Annadale et al., Bristow and Campbell, Allen models. In order to evaluate the performance of these models, a statistical test was performed by using Mean Bias Error and Root Mean Square Error. The obtained results show the different level performance, therefore it concluded that the Tanaka et al. (2006) and the Annandale et al. (2002) model provides good performances for the estimation of the hourly intensity and monthly intensity, respectively.
