Sunshine hours are the only long term, reliable and available measured information that can be used to reach highly accurate estimates of solar radiation values on the Earth surface. In this paper the sunshine duration is used to estimate monthly average daily solar radiation on a horizontal surface, it can be used to predict solar radiation in different climatic region of Iran. According to th...

In this study, an analysis of the monthly mean values of the fraction of the sky covered by clouds (C) of all types and the duration of bright sunshine hours (S) and global solar radiation on the horizontal surface (H) was carried out to establish relationship for solar radiation estimation for Bangladesh. The relationship between C and (1 − S/S0), where S0 is the maximum possible hours of suns...
