Solar power boom in Baden-Württemberg: Minister calls for clear steps!
Baden-Württemberg will reach its photovoltaic expansion target by 2025. Environment Minister Thekla Walker is calling for a clear federal stance.

Solar power boom in Baden-Württemberg: Minister calls for clear steps!
Baden-Württemberg is making great progress in the field of photovoltaics. The state is expected to reach its annual goal for the expansion of solar energy in July 2025. Environment Minister Thekla Walker reported that almost one gigawatt of solar energy had already been added in the first half of 2025. This means almost 988 megawatts, of which 673 megawatts are on roofs and 315 megawatts on open spaces, which is very close to the targets in the region.
This year's expansion target is a total of 1,150 megawatts. This illustrates the country's efforts to advance the energy transition. Walker noted that the dual use of areas in particular, such as combining photovoltaic systems with agricultural land (agri-photovoltaics) and covering parking areas with solar systems, offers great potential for increasing electricity production.
Support and challenges
The minister called on the federal government to lobby the EU Commission for higher remuneration for special solar systems in the Renewable Energy Act (EEG). She criticized the federal government's currently unclear stance on renewable electricity sources and warned of a possible decline in the number of expansions of solar projects.
Photovoltaics remains a central component of the energy transition in Baden-Württemberg. Expansion to roof areas and open spaces is essential, as the state climate protection law makes clear. By the end of September 2025, at least 0.2% of the area should be set aside for open-space photovoltaics in the regional plans. The planned areas include conversion areas, side verges along motorways and railways as well as disadvantaged arable and grassland areas. This regulation has been adjusted since the introduction of Solar Package I in spring 2024.
Insights into the legal framework
The Renewable Energy Sources Act (EEG) regulates the feed-in tariff for electricity from photovoltaic systems, with the compensation being paid through tenders by the Federal Network Agency. The lowest bids receive the corresponding compensation. In addition, the promotion of smaller open-space photovoltaic systems in disadvantaged areas is now possible.
The municipalities have the opportunity to decide on the areas for solar parks as part of the land-use planning. The Ministry for the Environment, Climate and Energy Sector has already sent information on planning aspects, location factors, legal requirements and citizen participation to the planning authorities. These measures are crucial to further advance the expansion of photovoltaics in Baden-Württemberg and to achieve the climate goals.
In summary, it can be seen that the development of photovoltaics in Baden-Württemberg is progressing. Nevertheless, clear statements and support from the federal government are required in order not only to secure this progress, but also to expand it.
The information comes from various sources, including reports Ludwigsburg24 about the country's successes. Further details on photovoltaics can be found at Ministry for the Environment, Climate and Energy Sector Baden-Württemberg.
