Rooftop solar in Poland typically costs about PLN 5,640 per kW installed, and household electricity is around PLN 0.814 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 PLN 32,430, make around 3,833 kWh a year, and save about PLN 3,120 a year. That is a payback of roughly 10.4 years.
