Rooftop solar in South Africa typically costs about R29,100 per kW installed, and household electricity is around R2.52 per kWh. The average sunshine is about 5.8 peak sun hours a day.
As a rough example, a 5 kW home system would cost about R167,400, make around 7,939 kWh a year, and save about R20,006 a year. That is a payback of roughly 8.4 years.
