Endüstriyel Bir Tesisin Çatı Güneş Enerjisi Uygulamasının Elektrik Enerjisi Üretimi, Finansal Değerlendirmeleri ve Çevresel Etkilerinin PVsyst Simülasyonu Kullanılarak Analiz Edilmesi: Ankara Örneği

Öz

Fosil yakıtların çevresel ve ekonomik anlamda olumsuz etkileri, enerji arzının yenilenebilir enerji kaynaklarından karşılanmasını özellikle son yıllarda zaruri hale getirmiştir. Yenilenebilir enerji kaynakları içerisinde uygulama kolaylığı ve amortisman sürelerinin kısa olmasından kaynaklı güneş enerjisinin popülerliği günden güne artmaktadır. Yaygın güneş enerjisi uygulamalarından biri de çatı güneş enerji sistemleridir. Bu çalışmada, Ankara ili Gaziosmanpaşa mahallesinde tekstil üzerine imalat yapan 5.000 m2 kapalı alana sahip bir fabrikanın elektrik tüketim verileri kullanılarak ve coğrafi konumu göz önünde bulundurularak PVsyst yazılımı ile şebekeye bağlı çatı güneş enerjisi uygulamasının simülasyonu gerçekleştirilmiştir. Dizi, DC kablolama ve sistem kayıpları göz önünde bulundurulduğunda performans oranı %77,73 olarak bulunmuştur. Toplam 674.099 kWh/yıl elektrik tüketimi gerçekleştirilen tesiste kurulan sistemle beraber 1.002.928 kWh/yıl elektrik üretimi yapılabileceği hesaplanmıştır. Son iki yılın enflasyon verileri göz önünde bulundurularak yıllık %30 enflasyon ve elektrik üretimi göz önünde bulundurularak 20 yıl sonra sistemden elde edilecek karın 36.406.905 USD olacağı tespit edilmiştir. Sistemin çevresel etkileri zaman içinde CO2 tasarrufu hesaplarak analiz edilmiş olup 30 yılın sonunda 12.362,1 ton CO2 emisyonu sağlanacağı hesaplanmıştır.

Analysis of Electric Power Generation, Financial Assessments and Environmental Impacts of Rooftop Solar Energy Application of an Industrial Facility Using PVsyst Simulation: Example of Ankara

Öz

The negative environmental and economic impacts of fossil fuels have made it essential to meet energy supply from renewable energy sources, especially in recent years. The popularity of solar energy is increasing day by day due to its ease of application and short amortization periods among renewable energy sources. One of the common solar energy applications is rooftop solar energy systems. In this study, an on-grid rooftop solar energy application was simulated with PVsyst software by using the electricity consumption data of a textile manufacturing factory with a closed area of 5,000 m2 in Gaziosmanpasa neighbourhood of Ankara province and considering its geographical location. Considering the array, DC cabling and system losses, the performance rate was found to be 77.73%. It has been calculated that 1,002,928 kWh/year of electricity can be generated with the system installed at the facility, which consumes 674,099 kWh/year of electricity in total. Considering the inflation data of the last two years, it has been determined that the profit to be obtained from the system after 20 years will be 36,406,905 USD, taking into account annual inflation of 30% and electricity production. The environmental impacts of the system were analyzed by calculating CO2 savings over time and it was calculated that 12,362.1 tons of CO2 emissions will be achieved at the end of 30 years.
