Mandatory photovoltaic requirement for companies starting in 2027
- Country-specific regulations already apply
- Company parking lots and commercial warehouses are affected
- PV obligation to be standardized
Another measure to reduce CO₂ emissions is the Solar mandate for businesses. This nationwide solar mandate will be available from 2027 in accordance with § 106 GModG.
Solar obligation for commercial and industrial roofs
In most federal states, photovoltaic systems already had to be installed in the past for new commercial buildings or roof renovations. This PV requirement affects non-residential buildings, such as production facilities, logistics centers, or office buildings, as well as municipal properties, and varies greatly between the individual federal states. From 2027, however, the European Parliament is planning a uniform solution, which is now through the Building Modernization Act (GModG) is implemented in Germany. In Section 106, the Federal Government sets the minimum standards for the federal states.
Large parking lots must supply green energy
A uniform solar mandate for large commercial parking lots on corporate sites does not yet exist in Germany. In Bremen, for example, all new large parking lots with 25 or more spaces must be equipped with solar modules, while in Schleswig-Holstein the PV mandate only applies starting from 100 spaces. In general, unlike in France, existing German parking lots do not yet have to be retrofitted with photovoltaic systems. However, this will change in the early 2030s.
Nationwide photovoltaic obligation for companies
At least for commercial real estate, planning security is provided by Section 106 of the GModG. Even though the regulations of the federal states still differ, a minimum standard has now been set, which will be further adapted and tightened in the coming years.
