Farklı Fotovoltaik Benzetim Yazılımlarının Karşılaştırmalı Analizi: 5,1 kWp Şebekeye Bağlı bir Fotovoltaik Sistemin Performansının Analizine İlişkin Örnek Çalışma

Abstract

Fotovoltaik (FV) sistemlerin kurulum maliyetlerinin yüksek olması sistemlerin yaygınlaşmasının önündeki en önemli engeldir. Bu nedenle günümüzde PV sistemlerinin eniyilenmesi konusunda çeşitli çalışmalar yapılmaktadır. FV sistemler panel eğim açısı, panel sayısı, panel tipi, panel yapısı, evirici ve akü grubu kapasitesi gibi ölçütler açısından eniyilenebilmektedir. FV sistemlerini en uygun şekilde tasarlamak için çeşitli kullanıcı dostu yazılımlar kullanılmaktadır. Bu yazılımlar, iklim verilerini kullanarak enerji üretimini tahmin eder ve buna göre ekonomik veriler sağlar. Ancak FV sistemlerin verimliliği iklim koşullarına bağlı olduğundan bu verilerin güvenilirliği değişmektedir. Bu makalede, güneş enerjisi sektöründe yaygın olarak kullanılan PV*SOL, PVsyst, RETScreen ve PVGIS yazılımlarının Kocaeli İli iklim koşullarında etkinliğinin değerlendirilmesi amaçlanmıştır. Kocaeli Üniversitesi Teknoloji Fakültesi binasına kurulan 5,1kWp çatı üstü PV sisteminin benzetimi gerçeğine uygun olarak bu yazılımlarla yapılarak hangi yazılımın gerçek enerji üretim verilerini tahmin etmede daha başarılı olduğu ortaya çıkarılmıştır. Karşılaştırmaya göre PV*SOL ve PVsyst ile elde edilen sonuçlar gerçek değerlere en yakın olduğundan en güvenilir yazılımlar olarak değerlendirilmiştir.

Comparative Analysis of Different Photovoltaic Simulation Software: Case Study on Analyzing the Performance of a 5,1 kWp Grid Connected Photovoltaic System

Abstract

The high installation costs of photovoltaic (PV) systems are the most important obstacle in the spread of systems; that’s why various studies are carried out on the optimization of PV systems today. Thus, PV systems can be optimized in terms of criteria such as inclination angle, PV module number, module type, module construction structure, and inverter. Different user-friendly software is used to design PV systems. Such software estimates energy production using climate data and provides economic data accordingly. However, the reliability of these data varies as the productivity of photovoltaic systems depends on climatic conditions. In this paper, it is aimed to evaluate the effectiveness of PV*SOL, PVsyst, RETScreen, and PVGIS software, widely used in the solar energy sector, under the climatic conditions of Kocaeli province. A 5,1kWp roof-top PV system installed on Kocaeli University Technology Faculty building is simulated with these programs to reveal which software is more successful in predicting real energy production data. According to comparison, PV*SOL and PVsyst are evaluated as the most reliable software since the yields obtained are the closest to the real energy values.
