Solar installation – Sachsen
Legal basis
- EEG 2023 – feed-in tariff and funding (federal level)
- Solarspitzengesetz – obligation to have a smart meter and control unit for new installations from 7 kWp (since 25.02.2025); without a control unit, the grid operator permanently limits feed-in to 60 % of installed capacity
- No state-specific solar obligation for private residential buildings
RECOMMENDED PROVIDERS
Solar obligation in Sachsen
No solar obligation for private residential buildings, neither for new builds nor existing buildings. Since 2024, a PV obligation has applied to state-owned properties as part of the Sächsisches Klima- und Energieprogramm – but this affects only state buildings and individual municipal buildings, not private owners.
Official obligations

|---|---|---|
| 1 | Register with grid operator | all installations |
| 2 | Register in MaStR | all installations |
| 3 | Smart meter + control unit | mandatory installation from 7 kWp; voluntary at 2–7 kWp, otherwise 60 % feed-in limitation |
| 4 | Tax office | from >30 kWp |
Planning permission: not required for roof-mounted installations. Exceptions: listed-building protection, ground-mounted installations.
