Bu çalışmamızda Diyarbakır koşullarında şebekeye bağlı Fotovoltaik bir sistemin kurulması durumunda kurulacak olan santralin PVsyst ve PVSOL programlarının deneme sürümleri kullanılarak simülasyonu yapılmıştır. Çalışma için Diyarbakır ilinde bulunan Teknik Lise’nin çatısı örnek çalışma alanı olarak seçilmiştir. Simülasyonlar sonucunda sistemin performans ve ekonomik analizi birlikte yapılmıştır. Analizler sonucunda her iki programında verilerinin birbirine yakın değerlerde çıktığı gözlemlenmiştir. Sistemin performans verileri analiz edilmiş, maliyeti hesaplanmış ve sistemin kendi maliyetini karşılama süresi hesaplanmıştır. Bu programlar böylece sistemimizin performansı hakkında hem yordama yapma hem de sistemin geri dönüş (amorti) süresi hakkında bize önemli katkıda bulunmuşlardır.
In this study, in case of a grid-connected photovoltaic system to be installed in Diyarbakır conditions, the plant to be installed was simulated using the trial versions of PVsyst and PVSOL programs. For the study, the roof of Technical High School in Diyarbakır province was selected as a sample study area. As a result of the simulations, the performance and economic analysis of the system were performed together. As a result of the analyses, it was observed that the data of both programs were close to each other. The performance data of the system was analyzed, the approximate cost was calculated and the time for the system to cover its own cost was calculated approximately. Thus, these programs made significant contributions to us both in terms of predicting the performance of our system and the payback period of the system. The novelty of this study lies in conducting a comparative performance and economic assessment of PVsyst and PVSOL simulation tools under the climatic conditions of Diyarbakır, which is one of the regions with the highest solar energy potential in Turkey but has been rarely investigated in the literature. Unlike previous works that mainly focus on general PV performance, this study evaluates the consistency and differences between two widely used simulation programs. The comparative analysis provides additional insights into the accuracy and reliability of software-based predictions, which can support more informed PV project planning and investment decisions in southeastern Turkey.
