In purely mathematical terms, the average household in apartment buildings consumes the following electricity:
Electricity with electric Water treatment
2 people -> 2,100 kWh -> 3,000 kWh
3 people -> 2,600 kWh -> 3,900 kWh
4 people -> 3,000 kWh -> 4,500 kWh
So what can you expect from a balcony power plant or mini PV? A system with two modules has 650 watts. You can expect an average of around 600kWh here. At a price of €0.28 per kWh, this corresponds to savings of €168 per year. A purchase price of €700 has been fully paid off after 4.2 years.
If electricity prices rise accordingly, the purchase of the system will pay off more quickly.

Guten Tag, ich möchte mir ein Balonkraftwerk zulegen. Mein Stromverbrauch liegt bei 2200 kWh. Mein Balkongeländer ist 2,8 m lang , einseitiger Überstand bis ca. 0, 2 m möglich,und 0,9 m hoch. Können Sie mir ein passendes Modul anbieten? Dank im Voraus
