Estimating GSR by Empirical models: Case Study for İskenderun, Turkey

Abstract

In this study, the predictability of Global Solar Radiation (GSR) data is investigated for Iskenderun region, which has a rich source of solar energy. Four different models were used to estimate GSR using current data. Linear, quadratic and exponential relationships were preferred among the parameters for absolute and stable results of these models. The empirical coefficients a, b and c of the models were calculated to estimate the average solar radiation of the region. The correlations between the obtained values from models and the current meteorological values were found to be consistent. As a result, a stable and reasonable approach was obtained for the estimation of GSR coming to the horizontal plane for the region. © 2019 IEEE.
