Analysis of sunshine hours and global solar radiation for Mardin of Turkey. 3rd International Symposium on Innovative Technologies in Engineering and Science (ISITES 2015), 03-07 July 2015, Valencia, Spainhttps://hdl.handle.net/20.500.12402/3942Having a strategic area, the energy industry has a critical importance in development policy of a country. Demands of renewable energy have increased in recent years due to energy price, global warming and climatic change. Therefore, the concerns about solar energy, one of the most important clean energy sources, have risen in the last decades. In this study, the empirical solar correlations developed in Turkey and some other countries were investigated for the province of Mardin, Turkey. The compatibility of solar radiation models inspected in terms of statistics was tested by determining the nearest model according to measured data. In addition to climate data which is specific to this region, prediction of Angstroms model was developed to estimate global solar radiation in Mardin. These models, since the mathematical models with the highest compatibility represent the measured data statistically well, it is understood that it can easily be used for daily global solar radiation on horizontal surfaces. The data of the model were obtained from Solar Energy Potential Atlas (GEPA) of Electrical Power Resources Survey Administration (EIE). Angstrom-type model parameters were developed to forecast sunshine average and to compute empirical coefficients for Mardin. Monthly predicted global solar radiation mean values were compared with observed values using statistical parameter coefficient of regression analysis (R²), mean bias error (MBE), root mean square error (RMSE), mean percentage error (MPE), mean absolute percentage error (MAPE), t-statistic (tsat) and the percent error (e) method developed in order to test the compliance of the models. The best developing ideal model was found to be quadric H/H0=-1,3049 (S/S0 ) 2 +2,2791(S/S0)-0,4143 and R 2 0,9492 determined in terms of utilizing the solar radiation potential in Mardin, Turkeyeninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-ShareAlike 3.0 United StatesSolar ModelsSolar EnergyStatistical ParametersConference Object
