Erzurum
Annual specific yield ~1,500 kWh/kWp
Solar data for Erzurum show an annual average of 2,600 sunshine hours and 1,620 kWh/m² global horizontal irradiation. Assuming a south-facing, optimum 36° tilt and 14% system losses (PR ≈ 93%), a 1 kWp system produces about 1,500 kWh a year.
Design note
High altitude and cold air raise efficiency; snow load and frost are design criteria.
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.
