Fotovoltaik Sistemlerde Performans Hesaplama Modellerinin Ankara (Orta Anadolu) için Karşılaştırılması

Abstract

Tekno-ekonomik analizlerde doğru fizibilite sonuçlarına erişebilmek için FV sistemlerin performansı gerçeğe yakın hesaplanmak zorundadır. FV sistem performansını tahminlemek için birçok model/hesaplama yöntemi vardır. Bu çalışmada, tüm yıl boyunca beş modül için (Mono-Si, Poly-Si, µc-Si/a-Si, CIS, ve HIT) Ankara’da ölçülmüş açık alan test verileri ile üç yazılımın (PV*Sol, PVSyst, HelioScope) aynı yer için tahmin sonuçları karşılaştırılmıştır. Analizler, performans hesaplama yöntemleri çok sayıda bağımlı ampirik parametre ve üretilen modüllerdeki farklılıkları içerdiklerinden dikkatli bir şekilde değerlendirilmesi ve kullanılması gerektiğini gösterdi. Karşılaştırma sonuçları yazılımların tahminleme doğruluklarının makul seviyede olduğunu ortaya çıkarmıştır ancak Heiloscope Ankara’nın (Orta Anadolu) iklim koşulları için diğerlerinden daha iyi performans göstermiştir.

Comparison of the Models of Solar PV Performance Calculations for Ankara – Middle Anatolia

Abstract

In a techno-economic analysis, to reach truthful feasibilities, accurate performance calculations of PV systems are a must. There are many models/calculation schemes to estimate PV module performances. In this study, we compare the estimation of three software (PV*Sol, PVSyst, HelioScope) using a whole year field data obtained in Ankara, for five module types (Mono-Si, Poly-Si, µc-Si/a-Si, CIS, and HIT). Our analysis showed that the calculation schemes of the performances should be carefully evaluated and used as they contain quite many located dependent empirical parameters, and distinctions in the fabricated modules. The comparisons showed that the estimation accuracies of the software are reasonable, yet software Helioscope performs better than the others for weather conditions of Ankara, Middle Anatolia.
