Rooftop solar in Finland typically costs about €1,390 per kW installed, and household electricity is around €0.232 per kWh. The average sunshine is about 2.8 peak sun hours a day.
As a rough example, a 5 kW home system would cost about €7,990, make around 3,833 kWh a year, and save about €889 a year. That is a payback of roughly 9 years.
