Özet:

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.
