Rooftop solar in Marshall Islands typically costs about $1,900 per kW installed, and household electricity is around $0.15 per kWh. The average sunshine is about 5.3 peak sun hours a day.
As a rough example, a 5 kW home system would cost about $10,930, make around 7,254 kWh a year, and save about $1,088 a year. That is a payback of roughly 10 years.
