Rooftop solar in Portugal typically costs about €1,230 per kW installed, and household electricity is around €0.232 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 €7,071, make around 6,844 kWh a year, and save about €1,588 a year. That is a payback of roughly 4.5 years.
