Solar data for Ankara show an annual average of 2,650 sunshine hours and 1,650 kWh/m² global horizontal irradiation. Assuming a south-facing, optimum 33° tilt and 14% system losses (PR ≈ 92%), a 1 kWp system produces about 1,520 kWh a year.
Design note
In cloudy winter months, bifacial modules can gain extra from snow reflection.
These values are long-term averages; year-to-year variation is around ±5%. Roof tilt, orientation and shading affect these values; use the simulator or request a survey for an exact production estimate.
