Registration of a balcony power plant is required by law because it feeds into the public power grid. In Germany, the Renewable Energy Sources Act (EEG) regulates the obligation to register mini solar systems. According to the EEG, system operators are obliged to report their balcony power plant to the local network operator within a certain period of time. The deadline can vary depending on the federal state, but is usually between four and six weeks after the system is put into operation.
Why is registration so important? Registering ensures that your balcony power plant is correctly integrated into the power grid and meets all technical requirements. In addition, registration in the Federal Network Agency's market master data register enables precise recording and monitoring of the mini solar systems installed in Germany. This is of great importance for controlling the energy transition and the implementation of energy goals.
Registration is important not only for legal reasons, but also for financial aspects. Only with proper registration are you entitled to the feed-in tariff for the solar power produced. This compensation can make an important contribution to the profitability of your mini solar system and amortize your investment more quickly.
If you do not register your balcony power plant, you may risk high fines or even a cease and desist order. In the worst case scenario, you could be banned from using your mini solar system. In addition, there may be a risk of feed-in tariff refunds being refunded if you have not registered your balcony power plant correctly.
To protect yourself from penalties and take full advantage of your mini solar system, you should follow these steps:
- Find out about the legal registration requirements for mini solar systems in your region.
- Register your balcony power plant with the local network operator on time.
- Register your system in the Federal Network Agency's market master data register.
- Check whether you meet the requirements for the feed-in tariff and apply for it if necessary.
