Estimation of Global Solar Radiation on Horizontal Surface Using Routine Meteorological Measurements for Different Cities in Iraq

Ali M. AL-Salihi, Maylaa M. Kadum and Ali J. Mohammed

Abstract: In this study, global solar radiation received on horizontal surfaces, maximum temperatures, sun shine duration and relative humidity for Baghdad, Mosul and Rutba are presented, analyzed, tabulated and plotted on graphs and discussed for three selected locations which represents different weather condition of Iraq. Mosul in the North, Baghdad in the middle, Rutba in the West of Iraq. A correlation between the measurements of global solar radiation and meteorological parameters were given for the considered location. The correlation and regression coefficients, standard errors of estimation, mean bias error, root mean square error and t-statics are calculated. The values of correlation coefficients vary from 89% for Rutba station to 97% for Baghdad station and the error of estimation are between 0.035 and 0.063, t-statics varied between 1.2 and 2.06 for Baghdad and Rutba, respectively. It can be concluded that the presented models reasonably predict the global solar radiation received on horizontal surfaces and the expected solar radiation behavior.
