Büyük şehirlerde süregelen kentsel dönüşüm çalışmaları, çok katlı konut binlarının elektrik ihtiyaçları için güneş pillerinin (PV) kullanımı konusunda fırsat sunmaktadır. Bu çalışmada, İstanbul’da 6 katlı (14 daireli) bir konut binası için PV enerji üretim kapasitesi PVsyst yazılımı ile hesaplanmış ve ev sahipleri için maliyetin geri dönüşü, fazla enerjinin sisteme satılmadığı durum için 23 yıl olarak hesaplanmıştır. Fazla enerjinin 13,3 sent/kWh fiyatla sisteme satılması halinde maliyetin geri dönüşü 6,6 yıl olabilmektedir. Konvansiyonel elektrik santrallerinin elektrik üretim maliyeti olan 6 sent/kWh’in dahi altında kalan 4 sent/kWh geri satım fiyatı ile 13,25 olarak hesaplanan yatırım geri dönüş süresi, yeni elektrik santralleri yerine PV ile kendi enerjisini üretme politikasının daha sürdürülebilir olmanın yanında ekonomik olarak da anlamlı olabileceğini göstermektedir.

Capacity Calculation and Subsidization Proposals for Rooftop PV Energy for a Residential Building in Istanbul

Abstract

Urban transformation works ongoing in the metropolitan cities pose an opportunity for application of PV energy for multi-story residential buildings. In this study, feasibility of a 6-story (14 units) residential building’s PV energy production capacity for İstanbul is calculated using PVsyst software and it is calculated that the payback time for the household owners is 23 years without any sell-back scheme. When excess energy is sold back to the grid at 13.3 cents/kWh, the payback time could reduce to 6.6 years. A sell-back price of 4 cents/kWh, that is lower than the 6 cents/kWh of production cost of conventional power plants, shows a payback time of 13.25 years, suggesting a policy to replace investment on new power plants with PV self-production as a sustainable yet more feasible alternative. Keywords: Rooftop PV system design, renewable energy, solar energy feasibility, energy production for self consumption, energy subsidization policy.
