Germany energy sector faces tension over proposed solar power feed-in caps

Germany is undergoing significant legislative and advisory shifts regarding its energy transition, driven by the upcoming EEG-Novelle 2027. A major point of contention is the proposed Paragraph 9, which seeks to cap the active power feed-in of solar installations under 100 kW at 50 percent of their installed capacity. This measure, intended by the Ministry for Economic Affairs and Energy to encourage self-consumption, has faced backlash from the automotive and solar industries. Companies including Elli (a VW subsidiary), Enpal, and Octopus Energy are calling for revisions, arguing the cap negatively impacts home storage systems and electric vehicle charging.

In response to market volatility and rising CO2 reduction requirements, new support programs are emerging. Starting in September 2026, initiatives such as a 700-euro voucher for low-income households to replace old appliances are expected to expand access to energy consulting. Organizations like Metropolsolar are also providing specialized guidance on solar technologies.

Additionally, the transition to new renewable energy laws has created urgency for homeowners. With the potential abolition of fixed feed-in tariffs for new systems starting January 1, 2027, experts warn that the legal date of commissioning—rather than just physical installation—will determine which compensation rules apply. This makes the timing of photovoltaic system integration critical for consumers.
