Balcony power plants as a complete set – Generate your own solar power for balconies, gardens, and patios

What is a balcony power plant?

A balcony power plant is a small solar system that you plug directly into a standard household outlet. Unlike a traditional rooftop system, you don’t need your own roof—a balcony, patio, garden, or carport will do.

How balcony power plants work

Solar energy is converted by the solar panels into direct current (DC) and then by the inverter into alternating current (AC). This electricity is fed into your home’s electrical system via a standard outlet. All connected devices prioritize using your own solar power—only when that isn’t enough do you draw power from the public grid.

Comparing balcony power systems: with or without storage

Without storage, you can only use your solar power while the sun is shining. With storage, you capture excess electricity during the day and use it in the evening or at night—this significantly increases your self-consumption rate, though it requires a correspondingly higher initial investment.

Registration in 2026: What You Need to Know

Balcony power plants with an inverter capacity of up to 800 watts and a module capacity of up to 2,000 watts peak do not require a permit. Since the introduction of Solar Package I, registration with the grid operator is no longer necessary—you register your system once, free of charge, in the Federal Network Agency’s market master data registry, and the grid operator is automatically notified.

Frequently Asked Questions About Balcony Power Plants

What are the real benefits of a balcony power plant?

You generate part of your electricity needs yourself, thereby lowering your electricity costs and becoming less dependent on your energy provider. The investment usually pays for itself within a few years.

How do I register a balcony power plant in 2026?

You register your balcony power plant once in the Market Master Data Register. A separate registration with the grid operator is no longer required, as long as your system complies with the limits of 800 W inverter power and 2,000 Wp module power.

How do the different balcony power plants in your store differ?

Our balcony power plants differ primarily in terms of power output, the number of solar modules, and whether they include an integrated storage system. This allows you to find the right solution based on the size of your balcony and your energy consumption.

How does a balcony power plant feed electricity into the grid?

The photovoltaic modules generate electricity, which is fed to an inverter. The inverter is connected to the home’s electrical system via a cable and feeds the electricity into it.

When is a balcony power plant a good investment?

With an average initial investment of €1,000, a balcony power plant pays for itself in about five years.
