Rooftop solar in France typically costs about €1,390 per kW installed, and household electricity is around €0.241 per kWh. The average sunshine is about 4.1 peak sun hours a day.
As a rough example, a 5 kW home system would cost about €7,990, make around 5,612 kWh a year, and save about €1,352 a year. That is a payback of roughly 5.9 years.
