Design and analyses of solar energy systems needs value of global solar radiation falling on the surface of the earth. In this study, thirty relative sunshine duration based regression models in the literature for determining the monthly average daily global solar radiation on a horizontal surface for Kocaeli were investigated. To indicate the performance of the models, the following statistical test methods are used: mean absolute bias error (MABE), mean bias error (MBE), mean absolute percent error (MAPE), mean percent error (MPE), root mean square error (RMSE). According to the statistical performance, Lewis model (Model 23), Model-18 (Jin et al.) and Model 8 (Bahel et al.) showed the best estimation of the global solar radiation on a horizontal surface for Kocaeli.
Güneş enerjisi ile çalışan sistemlerin tasarımını ve analizini yaparken, sistemin kurulacağı bölgenin güneş ışınım değerlerinin bilinmesi gerekir. Bu çalışmada, izafi güneşlenme süresine bağlı olarak geliştirilmiş literatürde mevcut 30 regresyon modelinin Kocaeli ilinde yatay düzleme gelen aylık ortalama günlük global (toplam) güneş ışınımının tahmini için kullanılabilirliği araştırılmıştır. Eşitliklerin performans değerlendirmesi için ortalama mutlak sapma hatası (MABE), ortalama sapma hatası (MBE), ortalama mutlak hata yüzdesi (MAPE), ortalama hata yüzdesi(MPE) Karekök hatası (RMSE) kullanılmıştır.
