Rooftop solar in Brunei typically costs about B$2,210 per kW installed, and household electricity is around B$0.194 per kWh. The average sunshine is about 4.6 peak sun hours a day.
As a rough example, a 5 kW home system would cost about B$12,710, make around 6,296 kWh a year, and save about B$1,221 a year. That is a payback of roughly 10.4 years.
