Rooftop solar in Brazil typically costs about R$7,200 per kW installed, and household electricity is around R$0.918 per kWh. The average sunshine is about 5.3 peak sun hours a day.
As a rough example, a 5 kW home system would cost about R$41,400, make around 7,254 kWh a year, and save about R$6,660 a year. That is a payback of roughly 6.2 years.
