Rooftop solar in Indonesia typically costs about IDR 23,600,000 per kW installed, and household electricity is around IDR 1,650 per kWh. The average sunshine is about 5 peak sun hours a day.
As a rough example, a 5 kW home system would cost about IDR 135,700,000, make around 6,844 kWh a year, and save about IDR 11,292,188 a year. That is a payback of roughly 12 years.
