Frequently Asked Questions

How large can a balcony power plant be without a permit?

In Germany, balcony power plants—also known as plug-in solar systems—may be operated with a capacity of up to 600 watts without a special permit. However, you must still register systems of this size with your local grid operator and the Market Master Data Registry. Operating such systems without registration can have legal consequences. It is important to always check with your grid operator and review the current regulations to ensure that all requirements are met.

When is a balcony power plant worth it?

A balcony solar power system is particularly worthwhile in Germany if you use a lot of electricity during the day, since you can use the electricity you generate yourself right away. By optimizing your self-consumption, you can lower your electricity costs. The payback period depends on various factors, such as the purchase cost, the current electricity price, and the amount of sunlight. Generally, a balcony solar power system can pay for itself within a few years. You’ll also be contributing to the energy transition and reducing your carbon footprint.

What is a balcony power plant?

A balcony power plant—often referred to in Germany as a "plug-in solar system" or "mini solar system"—is a small photovoltaic system that is connected directly to a home’s electrical grid. These systems are frequently installed on balconies, patios, or even on building facades. With the help of an inverter, the direct current (DC) generated is converted into alternating current (AC) and can be fed directly into the home’s electrical system via a standard outlet. Their primary purpose is to reduce one’s own electricity consumption and contribute to sustainable energy production.

How does a balcony power plant work?

A balcony power plant typically consists of one or two solar panels and an inverter. The solar panels convert sunlight into direct current. This direct current flows into the inverter, which converts it into alternating current that can be used by household appliances. The balcony power plant is then connected directly to the home’s electrical system via an outlet. This allows household appliances to use the solar power generated directly. Excess electricity that is not consumed immediately can be fed into the public grid, provided the system is properly registered with the grid operator.
