Rooftop solar in Bhutan typically costs about Nu.151,000 per kW installed, and household electricity is around Nu.13.2 per kWh. The average sunshine is about 4.2 peak sun hours a day.
As a rough example, a 5 kW home system would cost about Nu.868,000, make around 5,749 kWh a year, and save about Nu.75,884 a year. That is a payback of roughly 11.4 years.
