Abstract

Increasing global energy demand and fluctuating costs drive mankind to sustainable and cost-effective energy solutions. Renewable resources and relevant energy-generating technologies stand out as sustainable and eco-friendly options. In recent years, with a significant decrease in energy production costs, solar energy has come to the fore and increased its production share in the national economies. Solar based electricity production technologies are preferred not only with their cost-effectiveness but also with their contribution to combating climate change and achieving sustainable development targets. In this context; the aim of this study is to analyze the techno-economic and environmental aspects of a system consisting of photovoltaic (PV) modules that use solar energy as a source to provide electrical power demand in a campus located in Istanbul. The solar potential of the Turkish Naval Academy of the National Defense University has been calculated based on the available rooftop area for PV modules in the campus, the availability of per unit area of the roof, the efficiency, inverter efficiency and temperature effects on the PV array’s performance. The potential of the roof-mounted PV system was calculated using a modified calculation and then the feasibility of the proposed energy system has been developed by the RETScreen simulation tool. As a result, it is calculated that the proposed system will reach positive cash flow at the end of four years repayment period and continue its profit condition throughout the 25 years project life cycle, which will decrease the total greenhouse gas emissions by 93% and save 721.1 tons of crude oil. It has been evaluated as a cost-effective and environment-friendly application for the campus of the Turkish Naval Academy.

Özet

Artan küresel enerji talebi ve değişken maliyetler, insanoğlunu sürdürülebilir ve düşük maliyetli enerji çözümlerine yönlendirmektedir. Yenilenebilir kaynaklar ve buna benzer enerji üreten teknolojiler, ekonomik ve çevre dostu seçenekler olarak öne çıkmaktadır. Son yıllarda enerji üretim maliyetlerindeki ciddi azalma ile güneş enerjisi ön plana çıkmıştır ve milli ekonomiler içerisindeki üretim payı artmıştır. Güneş enerjisinden elektrik üreten teknolojiler sadece düşük maliyetli olmalarından dolayı değil, aynı zamanda iklim değişikliği ile mücadeleye ve sürdürülebilir kalkınma hedeflerine katkılarından dolayı da tercih edilmektedir. Bu çerçevede; bu çalışmanın amacı, İstanbul’da bulunan bir yerleşkenin elektrik talebini karşılayacak, güneş enerjisini kaynak olarak kullanan fotovoltaik (FV) modüllerden oluşan bir sistemin tekno-ekonomik ve çevresel yönlerini incelemektir. Milli Savunma Üniversitesi Deniz Harp Okulu’nun toplam güneş potansiyeli; yerleşkedeki FV modüllerin çatıdaki kullanılabilir alanına, çatının kullanılabilir birim alanına, verime, inventör verimine ve FV dizini üzerindeki sıcaklık etkisine bağlı olarak hesaplanmıştır. Önerilen çatı tip FV sisteminin potansiyeli, modifiye edilmiş bir hesaplama yöntemi ile belirlenmiş ve daha sonra önerilen FV sisteminin fizibilitesi RETScreen simülasyon aracı tarafından geliştirilmiştir. Sonuç olarak, önerilen sistemin dört sene geri ödeme süresi sonunda pozitif nakit akışına ulaştığı ve öngörülen 25 yıllık proje ömrünün devamında da kâr durumunu devam ettirdiği, toplam sera gazı salımında %93 oranında azaltım sağlayarak 721.1 ton ham petrol kullanımından tasarruf sağlayacağı hesaplanmış ve Deniz Harp Okulu yerleşkesi için maliyet-etkin ve çevre dostu bir uygulama olduğu değerlendirilmiştir.
