30kWp Çatı Tipi PV Santralinin 3 Yıllık Enerjik ve Ekonomik Analizi

30 kWp'lik bir çatı üstü fotovoltaik (FV) güneş enerji santrali, enerji dengesi denklemleri kullanılarak modellenmiş ve 3 yıllık enerji üretimi ile ekonomik getirisi kurulduğu gündeki tarife anlaşmasına göre hesaplanmıştır. Excel’de yapılan modelleme ve benzetim sonuçları ile sistemden saatlik bazda ölçülen elektrik üretimi verilerinin oldukça uyumlu olduğu görülmüştür. Sistem 1., 2. ve 3. yılda sırasıyla 45,35 MWh, 47,05 MWh ve 46,34 MWh enerji üretmiştir. FV sistemin performans oranının %84,50 ile %90,27 arasında değişirken, kapasite faktörünün de %17,26 ile %17,63 arasında değiştiği gözlemlenmiştir. 3 yılda üretim fazlası olarak 93,90 MWh elektrik enerjisi şebekeye verilirken, şebekeden 46,40 MWh enerji çekilmiştir. Enjekte edilen ve tüketilen elektriğin bedeli, sistemin kurulduğu andaki bağlantı anlaşması koşullarına göre hesaplanmış ve geri ödeme süresi yaklaşık 6 yıl olarak bulunmuştur.

3-Years Energetic and Economic Analysis of a 30kWp Rooftop PV Power Plant

A 30 kWp rooftop solar photovoltaic (PV) power plant was modelled using energy balance equations, 3-year energy production and its economic return is calculated according to the feed-in tariff agreement. Hourly measured electricity generation and Excel spreadsheet simulation results were closely compatible. The system generated 45.35 MWh, 47.05 MWh and 46.34 MWh of energy in year 1, 2 and 3, respectively. It has been observed that the performance ratio of the PV system varies between 84.50 % and 90.27 %, while the capacity factor varies between 17.26 % and 17.63%. While 93.90 MWh of electrical energy has been injected into the grid over a 3-year period, 46.40 MWh of energy has been taken from the grid. The price of electricity injected and consumed was calculated according to the FIT conditions at the time the system was installed, and the payback period was calculated as approximately 6 years.
