GİRESUN İLİ KOŞULLARINDA ŞEBEKEYE BAĞLI 100 KWP FOTOVOLTAİK SİSTEMİN TEKNİK PERFORMANS, EKONOMİK FİZİBİLİTE VE SERA GAZI EMİSYON ANALİZİ

Öz

Bu çalışmada Türkiye'nin Doğu Karadeniz Bölgesi’nde yer alan Giresun ili koşullarında 100 kWp kurulu güce sahip şebekeye bağlı bir fotovoltaik sistemin teknik performansı, ekonomik fizibilitesi ve sera gazı azaltım potansiyeli PVsyst V7.4.7 yazılımı kullanılarak incelenmiştir. Meteonorm 8.1 veri tabanına göre Giresun ilinin yıllık yatay küresel ışınım değeri 132,59 MWh/m² olup bu değer Türkiye'nin güney illerinin belirgin biçimde altında kalmaktadır. Simülasyon sonuçlarına göre sistem yıllık yaklaşık 134,31 MWh enerji üretmekte ve %90,28 performans oranı sergilemektedir. Bu değer, Türkiye genelindeki benzer çalışmaların üzerinde olup Karadeniz ikliminin termal avantajını açıkça yansıtmaktadır. P50-P90 analizi yıllık üretim aralığını 126,71-134,31 MWh olduğunu göstermiştir. Ekonomik analiz iki farklı senaryo için gerçekleştirilmiştir. Şebekeye satış senaryosunda (2,59 TL/kWh) geri ödeme süresi 14,4 yıl, öz tüketim senaryosunda (5,54 TL/kWh) ise 6,2 yıldır. Seviyelendirilmiş Enerji Maliyeti (LCOE), %20 iskonto oranı ve 30 yıllık sistem ömrü esas alınarak 8,85 TL/kWh olarak hesaplanmıştır. Elde edilen bulgular, mevcut tarife yapısında öz tüketim modelinin tek ekonomik seçenek olduğunu ortaya koymaktadır. IPCC Tier 1 metodolojisiyle gerçekleştirilen sera gazı analizi, sistemin yıllık 59,4-83,9 tCO₂ aralığında emisyon önlediğini göstermektedir.

TECHNICAL PERFORMANCE, ECONOMIC FEASIBILITY, AND GREENHOUSE GAS EMISSION ANALYSIS OF A 100 KWP GRID-CONNECTED PV SYSTEM: CASE OF GIRESUN, TURKIYE

Öz

This study examined the technical performance, economic viability, and greenhouse gas mitigation potential of a 100 kWp grid-connected solar system in Giresun province, situated in the Eastern Black Sea Region of Türkiye, utilizing PVsyst V7.4.7 software. The Meteonorm 8.1 database indicates that the annual horizontal global radiation value for Giresun province is 132.59 MWh/m², considerably lower than that of southern provinces in Türkiye. Simulation outcomes indicate that the system generates approximately 134.31 MWh of energy per annum and demonstrates a performance efficiency of 90.28%. This value surpasses that of comparable research throughout Türkiye and distinctly illustrates the thermal benefits of the Black Sea environment. The P50-P90 study indicated an annual production range of 126.71 to 134.31 MWh. An economic analysis was conducted for two distinct scenarios. In the grid-to-grid scenario (2.59 TL/kWh), the payback period is 14.4 years; conversely, in the self-consumption scenario (5.54 TL/kWh), it is 6.2 years. The Levelized Cost of Energy (LCOE) was determined to be 8.85 TL/kWh, utilizing a 20% discount rate and a 30-year system lifespan. The results indicate that the self-consumption model is the sole cost-effective alternative under the existing tariff framework. Analysis of greenhouse gases conducted using the IPCC Tier 1 methodology indicates that the system mitigates emissions between 59.4 and 83.9 tCO₂ per year.
