Funding for balcony power plants in Baden-Württemberg: A comprehensive guide

Green energy from your own balcony: funding opportunities in Baden-Württemberg

A balcony power plant offers both tenants and homeowners an excellent opportunity to actively participate in the energy transition. These plug-in solar systems are particularly user-friendly thanks to their plug-and-play functionality - simply plug in and energy production begins. In the long term, they help reduce electricity costs. Various federal states and cities promote the acquisition of such systems. In our guide you will find out how you can benefit from these subsidies and significantly reduce your expenses for balcony power plants.

Balcony power plants are experiencing an impressive boom in Stuttgart. In 2022, Stuttgarter Netze, the local network operator, registered the installation of 132 of these systems - a more than three-fold increase compared to the previous year. However, the actual number is believed to be much higher because many households do not officially register their mini solar systems.

This trend clearly shows that more and more people want to take their power supply into their own hands. The increased interest in an independent energy supply has undoubtedly contributed to the popularity of balcony power plants. The developments in Stuttgart are a reflection of a nationwide trend in Baden-Württemberg, a federal state that is ahead in Germany when it comes to renewable energy. With a series of laws and programs to promote renewable energies, Baden-Württemberg is setting strong accents for a greener future.

Electricity generation through solar energy is particularly interesting for residents in Baden-Württemberg and Bavaria. According to data collected by the DWD (German Weather Service), the sun shone the most in Baden-Württemberg and Bavaria in 2023, with 1,855 hours of sunshine each in these federal states. In addition to numerous attractive regional subsidies, the geographical location for self-generated electricity from solar energy could hardly be better.

The installation of a balcony power plant can be rewarded with a bonus of up to 500 euros. However, this financial support is not available across the board as funding programs vary significantly at regional level. To give you an overview of which cities or federal states offer which type of funding and how you can apply for this funding, we have created a detailed list.
