Rooftop solar in South Korea typically costs about KRW 2,930,000 per kW installed, and household electricity is around KRW 182 per kWh. The average sunshine is about 3.6 peak sun hours a day.
As a rough example, a 5 kW home system would cost about KRW 16,850,000, make around 4,928 kWh a year, and save about KRW 896,805 a year. That is a payback of roughly 18.8 years.
