Germany’s energy transition is undergoing a major regulatory shift as the government moves to reform the Renewable Energy Act (EEG). The federal Ministry for Economic Affairs and Energy has characterized the upcoming changes as a “paradigm shift,” marking the end of the EEG as an “all-round-care package.” Central to the reform is a shift in focus toward large-scale, cost-efficient ground-mounted solar plants, moving away from the long-term subsidies that previously supported small-scale residential systems. For systems under 25 kWp, the current 20-year guaranteed feed-in tariff will be phased out. While homeowners commissioning systems by the end of 2026 can still secure existing rates, systems commissioned after January 1, 2027, will face a much shorter three-year transitional payment period. By mid-August 2026, Germany reached its solar expansion target for the year, with over 128 GWp of photovoltaic installations installed.
