Rooftop solar in Zambia typically costs about ZK39,400 per kW installed, and household electricity is around ZK3.45 per kWh. The average sunshine is about 5.5 peak sun hours a day.
As a rough example, a 5 kW home system would cost about ZK226,600, make around 7,528 kWh a year, and save about ZK25,972 a year. That is a payback of roughly 8.7 years.
