Rooftop solar in Solomon Islands typically costs about SI$14,400 per kW installed, and household electricity is around SI$1.26 per kWh. The average sunshine is about 4.9 peak sun hours a day.
As a rough example, a 5 kW home system would cost about SI$82,800, make around 6,707 kWh a year, and save about SI$8,451 a year. That is a payback of roughly 9.8 years.
