Sonnenstrom boom in Baden-Württemberg: Minister demands clear steps!

Baden-Württemberg is making great progress in the field of photovoltaics. In July 2025, the state is expected to reach its annual goal for the expansion of solar energy. Environmental Minister Thekla Walker reported that almost a gigawatt solar energy was already added in the first half of 2025. This means almost 988 megawatts, including 673 megawatts on roof areas and 315 megawatts on open spaces, which is very close to the targets in the region.

This year's expansion goal is a total of 1,150 megawatts. This illustrates the country's efforts to advance the energy transition. Walker found that the double use of areas, such as the combination of photovoltaic systems with agricultural areas (Agri-Photovoltaic) and the roofing of parking space with solar systems, offer great potential to increase electricity production.

funding and challenges

The minister asked the federal government to work at the EU Commission for higher remuneration for special solar systems in the Renewable Energy Sergien law (EEG). She criticized the currently unclear stance of the federal government to renewable power sources and warned of a possible decline in the expansion of solar projects.

Photovoltaics remains a central component of the energy transition in Baden-Württemberg. The expansion on roof areas and open spaces is essential, as the State Climate Protection Act illustrates. By the end of September 2025, at least 0.2% of the area for open space photovoltaics are to be determined in the regional plans. The intended areas include conversion areas, side edge strips along motorways and rail paths as well as disadvantaged arable and grassland areas. This regulation has been adjusted in spring 2024 since the introduction of solar package I.

insights into the legal framework

The Renewable Energy Sergies Act (EEG) regulates the feed-in tariff for electricity from photovoltaic systems, with the remuneration of the Federal Network Agency. The lowest commandments receive the corresponding remuneration. In addition, the promotion of smaller open space photovoltaic systems in disadvantaged areas is now made possible.

The municipalities have the opportunity to decide on the areas for solar parks as part of the land use planning. The Ministry of the Environment, Climate and Energy Management has already sent information on planning aspects, location factors, legal requirements and for citizen participation to the planning providers. These measures are crucial to further promote the expansion of photovoltaics in Baden-Württemberg and to achieve the climate goals.

The information comes from various sources, among other things reports ludwigsburg24 about the country's success. Further details on photovoltaics can be found in the Ministry of the Environment, Climate and Energy Industry Baden-Württemberg .
