Rooftop solar in Germany typically costs about €1,310 per kW installed, and household electricity is around €0.378 per kWh. The average sunshine is about 3 peak sun hours a day.
As a rough example, a 5 kW home system would cost about €7,533, make around 4,106 kWh a year, and save about €1,552 a year. That is a payback of roughly 4.9 years.
