Solar installation – Saarland
Legal basis
- EEG 2023 – feed-in tariff and funding (federal level)
- Solarspitzengesetz – smart meter and control box required for new systems from 7 kWp (since 25.02.2025); without a control box, the grid operator permanently reduces feed-in to 60 % of installed capacity
- § 12a, § 12b Landesbauordnung Saarland – solar requirement for public and commercial buildings and larger new car parks (since 26.04.2025)
- PV-ready requirement for private new-builds and roof renewals from 50 m² roof area (since 01.09.2025)
RECOMMENDED PROVIDERS
Solar requirement in Saarland
No full solar requirement for private residential buildings. However, there is a PV-ready requirement: Since 1 September 2025, new-builds and roof renewals with at least 50 m² roof area must be planned so that a photovoltaic system can be installed later. Immediate installation is not required.
For public and commercial buildings and larger new car parks, however, a genuine solar requirement has applied since 26 April 2025 for new construction or roof refurbishment (§ 12a and § 12b LBO Saarland).
Individual municipalities may additionally introduce their own solar requirement for private residential buildings by local statute. So far, no municipality in Saarland has made use of this option (as at 07/2026).
