Want to lower your electricity bills and take control of the energy transition?

With the Balcony Power Plant Audit App, planning your mini solar system is easier than ever. Before you invest any money, our app helps you find out how much electricity you can actually generate and when your balcony power plant (BPP) will become financially viable.

How does the app work? Our analysis tool guides you to a precise result in just a few steps:

Location Check: Enter your address. The app uses geographical data to determine the exact solar irradiance at your location in Germany, Austria, or Switzerland.

Determine Orientation: Where is your balcony or terrace located? Simply select the side (south, southwest, east, etc.). The app calculates the optimal tilt angle for maximum yield.

Costs & Prices: Enter the purchase price of your complete set and your current electricity price (cents/kWh).

Detailed Analysis: You'll immediately receive a clear graphic and data on:

Annual electricity production (kWh).



























... Annual savings in euros.

Payback period: The exact year you start making a profit.

Why a balcony power plant audit? A balcony power plant is a great investment, but the yield depends heavily on shading and orientation. Our app takes the guesswork out of it. Whether 600W, 800W, or more – we calculate the potential based on real-world factors.
