Overview
- A leaked referentenentwurf published in mid-June proposes removing the fixed feed-in tariff for new solar systems up to 25 kilowatts and would, in some reports, limit grid feed-in to half of installed capacity.
- Independent modelling by the research institute Aquu for the Solarenergie-Förderverein shows a 10 kW PV system with a 10 kWh battery would see usable annual output fall from about 11,000 kWh to roughly 3,430 kWh under zero-export rules, with about 7,600 kWh curtailed.
- The study finds the cost of self-generated power would rise from about €0.10/kWh to €0.31/kWh and amortisation would stretch from roughly 15.6 years to more than 25 years, making many rooftop systems financially unattractive.
- Practical options left to households would be direct marketing to the electricity market or enforced non-export; Aquu estimates direct-marketing gross revenue around €250/year and net receipts of about €90 after fees, which would not cover smart‑meter and control costs.
- Industry groups denounce the draft as an ‘energy-policy disaster’ that would discourage full roof installations, the government says it will press ahead for budgetary and market reasons, and the proposal remains a draft that must pass consultation and legislation before becoming law.
