Solar data for Bursa show an annual average of 2,400 sunshine hours and 1,500 kWh/m² global horizontal irradiation. Assuming a south-facing, optimum 33° tilt and 14% system losses (PR ≈ 93%), a 1 kWp system produces about 1,400 kWh a year.
Design note
In a region with many cloudy days, the low-light performance of N-type modules is beneficial.
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.
