Rooftop solar in Papua New Guinea typically costs about K7,030 per kW installed, and household electricity is around K0.615 per kWh. The average sunshine is about 4.8 peak sun hours a day.
As a rough example, a 5 kW home system would cost about K40,420, make around 6,570 kWh a year, and save about K4,041 a year. That is a payback of roughly 10 years.
