Rooftop solar in Switzerland typically costs about CHF1,900 per kW installed, and household electricity is around CHF0.24 per kWh. The average sunshine is about 3.6 peak sun hours a day.
As a rough example, a 5 kW home system would cost about CHF10,930, make around 4,928 kWh a year, and save about CHF1,183 a year. That is a payback of roughly 9.2 years.
