Solar Power Expansion Drops to 1.1 Gigawatts in January 2025

In the month leading up to 2025, Germany saw an expansion of 1.1 GW in photovoltaic systems. In addition, the Federal Network Agency significantly revised the December data upwards. Instead of the previously reported 1.4 GW, the net addition in that month turned out to be 1.8 GW.

A Drop in Solar Installations

January 2025 witnessed a downturn in the installation of photovoltaic systems in Germany, sliding down to approximately 1.1 Gigawatts (GW) according to the Federal Network Agency. This particular figure - a net installation of 1,123 Megawatts (MW) - accounted for potential late registrations, an occurrence that usually swells the numbers following an initial report. Counting these adjustments, the actual net installation recorded was merely 1,021 MW as of February 13, 2025.

A prime illustration of this phenomenon took place in December 2024. Initially, the Federal Network Agency reported a figure of 1,438 MW. However, the correct data gleaned from the Energy Source Database as of February 13 revealed a significant surge in installations, tallying up to 1,823 MW.

Milestones Reached and Future Ambitions

This surge in installations lifted the total count of German PV systems over the 100 GW mark for the first time in history. In order to reach the ambitious goal of 215 GW by 2030 set by the Federal Network Agency, Germany would need to add an average of 1,608 MW monthly.

Of the additions registered in January, 756 MW were credited to building solar systems. Open area installations accounted for 237.5 MW, with other systems and balcony solar power plants amounting to 13 MW and 19.3 MW respectively. At the federal state level, Bavaria outshined North Rhine-Westphalia, Baden-Württemberg, and Lower Saxony.

Wind energy on land also saw a considerable January increase of 194 MW, with the majority originating from North Rhine-Westphalia. As for new offshore wind energy installations and bio-energy, there were none and a mere 6 MW added, respectively.

To support this fast-paced growth in solar and renewable energy, reliable energy storage is essential. That’s where energy storage companies like ACE Battery come in, offering advanced battery solutions that help store solar power for when it’s needed most.
