INTRODUCTION
Solar radiation data for Antalya (36°53' N, 30°42' E) in Turkey were used to test the applicability of twenty six models available for computing the monthly average daily global radiation on a horizontal surface. The models were compared on the basis of statistical error tests using the mean percentage error (MPE), root mean square error (RMSE) and the mean bias error (MBE). According to our results, the Samuel model below (Samuel T.D.M.A. Estimation of global radiation for Srilanka.
Turkey is a high insolation country in that the number of sunshine hours amount to about 2640 h/year . Therefore, qualification of this renewable energy capacity e€ectively through the empirical models plays an important role in developing renewable energy technologies and the sustainability of natural resources. The objective of this paper is to validate twenty sixmodels to predict the monthly average daily global radiation on a horizontal surface against an independent data set for Antalya (Turkey) and, thus, to select the most accurate model.
Solar radiation is the fundamental renewable energy source that sustains the biosphere and drives its self-organization. Solar radiation data is essential to the work of energy planners, engineers and agricultural scientists. Several empirical models have been developed to calculate the solar radiation using various parameters. The objective of this paper is to validate twenty six models to predict the monthly average daily global radiation on a horizontal surface against an independent data set for Antalaya (36°53' N, 30°42' E) (Turkey), and thus, to select the most accurate model. The models were compared on the basis of statistical error tests.
According to our results, the Samuel model below showed the best estimation of global solar radiation on a horizontal surface for Antalya by means of the MPE (1.5%), RMSE (0.27MJ/m 2 ) and MBE (-0.02 MJ/m 2) statistical tests:
