In recent years, most federal states have passed legal regulations that oblige building owners to install solar systems in new buildings or roof renovations. These solar obligations lack economic justification and can drive up construction costs considerably: If half of a 100 square metre roof is covered, the construction costs for an exemplary roof extension increase by more than 27 percent and for a roof renovation by as much as more than 58 percent.
Instead of making the construction of residential and commercial buildings more expensive and complicated due to solar obligations, federal states should therefore abolish these regulations in order to facilitate the wider availability of residential and commercial space.
**Different solar obligations in the federal states**
In 2022, Baden-Württemberg was the first federal state to introduce a solar obligation for new residential buildings. Ten federal states have now passed similar regulations.
Six federal states, including Baden-Württemberg, Berlin, Bremen, Hamburg, Lower Saxony and North Rhine-Westphalia, stipulate the installation of solar energy systems for both residential and non-residential buildings. In three federal states – Bavaria, Brandenburg and Schleswig-Holstein – only the construction of new commercial buildings is subject to solar obligations. Rhineland-Palatinate is a special case in that the state only stipulates the ‘solar capability’ of new roof installations for residential buildings.
The respective regulations vary considerably in terms of the roof area to be covered, the capacity to be installed and the applicable exemptions. A total of eight federal states have also included roof refurbishments in their regulations.
In contrast, in six federal states – Hesse, Saarland, Saxony, Saxony-Anhalt, Schleswig-Holstein and Thuringia – there are no statutory regulations on the installation of solar systems, which would make the construction of new homes, commercial buildings or roof renovations more expensive.
In Hesse, solar energy is only mandatory for car parks. Several federal states have also committed to equipping buildings owned by the state or municipalities with solar panels.
