Rooftop solar in Singapore typically costs about SGD 2,950 per kW installed, and household electricity is around SGD 0.348 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 SGD 16,960, make around 6,296 kWh a year, and save about SGD 2,191 a year. That is a payback of roughly 7.7 years.
