Rooftop solar in North Korea typically costs about ₩1,540,000 per kW installed, and household electricity is around ₩135 per kWh. The average sunshine is about 4.2 peak sun hours a day.
As a rough example, a 5 kW home system would cost about ₩8,860,000, make around 5,749 kWh a year, and save about ₩776,081 a year. That is a payback of roughly 11.4 years.
