Correlation between estimated and measured hourly and daily solar fluxes over Bahrain


  • Ragab, F. M.
  • Som, A. K.


Global radiation predictions can be carried out by many methods. However, the simplest method is the addition of direct and diffuse components of the solar flux. In this paper, the actual data for the direct, diffuse and global radiations as measured by Eppley precision pyranometers have been analysed. Correlations for the hourly fluxes were carried out. The comparison of the predicted and measured data for the two months of April and September 1990 is significant, except for low sun angles. The presence of clouds decreases the direct flux and relatively increases the diffuse flux.
