Günümüzde artan enerji maliyetleri ve çevresel kaygılar, sanayi tesislerini sürdürülebilir enerji kaynaklarına yönlendirmektedir. Bu bağlamda, fabrikaların çatılarına kurulan Güneş Enerjisi Santralleri (GES), çevre dostu ve ekonomik bir enerji üretim çözümü sunmaktadır. Çatı GES sistemleri, fabrikaların mevcut çatı alanlarını değerlendirmesine olanak tanırken, elektrik ihtiyacının önemli bir kısmını karşılayarak enerji faturalarında ciddi tasarruf sağlar. Ayrıca karbon salımını azaltarak çevresel sürdürülebilirliğe katkı sunar. Bununla birlikte, sistem kurulumunda çatı yapısının uygunluğu, ilk yatırım maliyeti ve bürokratik süreçler gibi bazı zorluklar da bulunmaktadır. Tüm bu etkenler göz önünde bulundurulduğunda, çatı GES uygulamaları; uzun vadeli ekonomik faydaları, enerji arz güvenliği ve çevresel kazanımları nedeniyle fabrikalar için stratejik bir yatırım haline gelmiştir. Bu çalışmada Türkiye’de Düzce ilinde yer alan bir beton fabrikasının çatısına kurulan GES’in fabrikanın enerji tasarrufu performansı ve çevresel etkilerinin incelenmesi amaçlanmaktadır. Elde edilen sonuçlar, güneş radyasyonunun Düzce yoğun olduğu aylarda GES’ten kullanılan elektriğin şebekeden kullanılan elektriğe göre daha fazladır. Ancak, 8 ay için fabrikada ihtiyaç duyulan enerjinin ortalama %46,02’sı çatıya kurulan GES’ten karşılanmıştır. Ekonomik açıdan, kurulan GES’in kendini amorti etme süresi yaklaşık olarak hesaplanmıştır. Çevresel açıdan, GES kurulumu ile eskiye göre 1100 ton CO2 salınımı azalmıştır. Bu değer, fabrikanın GES kurulmadan önceki haline göre %76 daha az CO2 salınımı anlamına gelmektedir. Sonuç olarak, fabrikanın çatısına yerleştirilen GES’in ekonomik ve çevresel yönlerden oldukça katkı sağladığı görülmektedir.

Today, increasing energy costs and environmental concerns direct industrial facilities to sustainable energy sources. In this context, PV Power Plants (PVPP) installed on the roofs of factories offer an environmentally friendly and economical energy production solution. Rooftop solar power plants allow factories to utilize their existing rooftop areas, while meeting a significant portion of their electricity needs and providing significant savings on energy bills. It also contributes to environmental sustainability by reducing carbon emissions. However, there are some difficulties in system installation, such as the suitability of the roof structure, initial investment cost and bureaucratic processes. Considering all these factors, rooftop solar power plant applications have become a strategic investment for factories due to their long-term economic benefits, energy supply security and environmental gains. This study aims to investigate the energy saving performance and environmental impacts of a PVPP installed on the roof of a factory in Düzce, Türkiye. The results show that in the months when solar radiation is intense in Düzce, the electricity used from PVPPs is higher than the electricity used from the grid. However, an average of 46.02% of the energy needed in the factory for 8 months was provided by the PVPP installed on the roof. From an economic perspective, the payback period of the installed solar power plant system is calculated as approximately 3 years. From an environmental perspective, with the installation of the PVPP, CO2 emissions have decreased by 1,100 tons compared to the past. This value means that the factory emits 76% less CO2 compared to the factory before the installation of the PVPP. As a result, it is seen that the PVPP placed on the roof of the factory contributes significantly to economic and environmental aspects.
