Study global solar radiation based on sunshine hours in Iraq

Abstract EN

In this paper the solar radiation over the region of Iraq was studied and calculated.

Empirical models for the Estimation of Global Solar Radiation depending on Sunshine Hours on Horizontal Surface in Various Cities of Iraq were produced (Baghdad, Rutba and Nassiria.

In developing countries like Iraq measurement ability of the global solar radiation and its components is not available for all locations due to which there is a requirement of using different models (FAO, Rietveld, Glover and Tiwari-Sangeeta) for the estimation of global solar radiation that use climatological parameters of the locations.

Empirical constants for these models have been estimated and the results obtained by these models have been tested statistically.

The results show a good agreement between estimated and measured values.
