From 1 January 2030 a solar energy installation must be installed on a new residential building and on a new roofed car park that is physically adjacent to a building. The duty is triggered by the construction project and does not expire. The duty does not apply where installing a solar energy installation is technically impossible, functionally not feasible or economically unreasonable, or where it conflicts with other public-law provisions; nor where measures under Section 40(1) have to be taken for the building; nor to buildings serving national and alliance defence. The Länder may impose stricter requirements. Further references: Section 106(2) to (5) as in force from 1 January 2027.

Ab dem 1. Januar 2030 ist eine Solarenergieanlage auf einem neuen Wohngebäude und auf einem neuen überdachten Parkplatz, der physisch an ein Gebäude angrenzt, zu errichten. Die Pflicht wird durch das Bauvorhaben ausgelöst und läuft nicht aus. Die Pflicht entfällt, soweit die Errichtung einer Solarenergieanlage technisch unmöglich, funktional nicht realisierbar oder wirtschaftlich unzumutbar ist oder anderen öffentlich-rechtlichen Vorschriften widerspricht; ferner, wenn für das Gebäude Maßnahmen nach § 40 Absatz 1 zu ergreifen sind, und für Gebäude, die der Landes- und Bündnisverteidigung dienen. Die Länder können weitergehende Anforderungen stellen. Weitere Fundstellen: § 106 Absätze 2 bis 5 in der ab 1. Januar 2027 geltenden Fassung.
