Launched 282MW Rooftop Photovoltaic Project

Germany’s Federal Network Agency (Bundesnetzagentur) has launched the country’s latest rooftop solar PV tender, seeking 282 MW of capacity.

Germany Advances Solar Expansion with Second 2025 Rooftop Tender, as PV Capacity Surpasses 100 GW Milestone

Germany continues to accelerate its renewable energy transition with the launch of the second of three rooftop solar tenders scheduled for 2025, targeting a combined 1.1 GW of photovoltaic (PV) capacity this year. The latest tender, with a bid deadline of June 2, 2025, maintains a competitive ceiling price of €0.104/kWh ($0.118/kWh), following a downward adjustment by the German Federal Network Agency (Bundesnetzagentur) at the end of 2024 to reflect declining solar development costs.

Strong Market Interest with Consistent Oversubscription
Germany’s rooftop and ground-mounted solar tenders have seen robust participation, underscoring strong investor confidence in the country’s renewable energy market. The previous rooftop tender in March 2025 awarded 315 MW of capacity, attracting bids 1.2 times oversubscribed, with 88 successful projects securing contracts at an average price of €0.091/kWh—well below the maximum threshold.

The trend of oversubscription extends to large-scale solar projects as well. The latest ground-mounted PV tender awarded a record 2.6 GW of capacity, with submissions reaching 3.8 GW, demonstrating the high demand for utility-scale solar development.

Germany Surpasses 100 GW Solar Milestone
The successful tendering process has significantly contributed to Germany’s solar expansion, with the nation’s total installed PV capacity recently exceeding 100 GW. This achievement reinforces Germany’s position as a leader in solar energy adoption within Europe and aligns with its ambitious Renewable Energy Act (EEG) targets, which aim for 80% renewable electricity by 2030.

As the second rooftop tender progresses, industry observers anticipate continued strong competition, further driving innovation and cost efficiency in Germany’s solar sector. The results of the latest large-scale tender, including the full list of winning bidders, are now available, providing insights into the evolving dynamics of Germany’s solar energy market.

With two more tenders remaining in 2025, Germany remains on track to significantly expand its solar capacity, supporting both its climate goals and energy security strategy.
