Germany’s March 2025 Solar Additions Drop Sharply to 787 MW

Germany’s Federal Network Agency (Bundesnetzagentur) has recorded a sharp decline in the newly registered solar PV capacity for the month of March 2025, at 787.2 MW. 

It is a decline from 1.4 GW the country installed in March 2024 and 1.66 GW in February 2025. The latter is a revised number from the 1.53 GW the agency earlier reported for the previous month (see Germany Installed 1.53 GW New Solar Capacity In February 2025).

The agency said there were 74,435 systems registered in the month of March. Rooftop PV systems with a combined 385.5 MW were installed during the reporting month, compared to over 532.8 MW in the previous month. Ground-mounted solar PV installations totaled 280.5 MW, compared to over 1.1 GW in the month before.  

With March numbers coming in, Germany’s Q1 2025 registered systems totaled 3.71 GW, and its cumulative capacity reached 103.84 GW with more than 5 million PV systems installed.

Meanwhile, the new coalition government of Germany, comprising the conservative CDU/CSU alliance and the Social Democrats, has agreed to stick to the country’s existing target to become climate-neutral by 2045 under their Coalition Agreement. This means the country will phase out coal by 2038 and continue to expand renewables as well as storage.

For solar energy, it has committed to expanding it with storage to support the grid. The role of prosumers will become more central under the new regime, while solar on farmland, parking lots and floating PV will be promoted to ensure optimal use of available space. The registration process will be expedited through digitalization and standardization.

This means that during the new government’s administration until 2029, Germany will continue to chase the 215 GW combined PV target by 2030. However, Bundesnetzagentur calculates monthly installations to expand to over 1.61 GW to be able to reach the overarching target.
