New Milestone: Germany Surpasses the 100-Gigawatt Solar Threshold

The solar offensive in Germany has shattered all previous records in 2025, solidifying the country’s position as Europe’s leading solar power. Driven by the “Solar Package I” and unprecedented momentum in the commercial and industrial sectors, 2025 has become the most successful year in German photovoltaic history.

As confirmed by the Federal Network Agency (Bundesnetzagentur), more than 1.1 million new solar systems were installed in 2025. This brought the total cumulative capacity to approximately 118 gigawatts (GW) by early 2026. Over 16 GW of new capacity was added last year alone—a significant increase over the already strong preceding years. A particularly strong trend continued with plug-in balcony solar systems: with over 430,000 new registrations in 2025, there are now more than 1.5 million of these compact systems active on the grid.

The distribution of new installations shifted significantly in 2025:

• 42% was attributed to the Commercial and Industrial (C&I) sector, which saw massive growth due to simplified grid connections and higher tender limits.
• 33% was realized in the Utility-Scale sector, dominated by innovative concepts such as Agri-PV and biodiversity solar parks.
• 25% of the expansion came from the Residential sector, which remained highly attractive due to record-low system prices despite lower feed-in tariffs.

Germany now has a total of approximately 6 million solar power systems in operation. In 2025, they generated around 87 billion kilowatt-hours (TWh) of clean electricity, covering roughly 16% of Germany’s total gross electricity consumption. Combined with wind power and biomass, nearly 60% of German energy came from renewable sources for the first time in 2025.

Experts predict a continuation of the boom for the current year, 2026. Although changes in Asian export regulations as of April 2026 have led to slightly rising module prices, the new Storage Offensive is compensating for this: with an installed storage capacity of 25.5 GWh, solar power in Germany has become baseload-capable. According to recent surveys, over 80% of property owners with suitable roof space plan to expand their systems or retrofit them with intelligent battery storage by 2030.

Thanks to the removal of bureaucratic hurdles through “Solar Package II” and the new prioritization of large-scale storage in rural areas, Germany remains the driving engine of the European energy transition.
