Germany installed 838.5 MW of solar PV capacity in April 2025, marking a 37% YoY decline
Total installed solar PV capacity reached 104.85 GW, including the 4.65 GW added during 4M 2025
Solar remains the country’s top renewable energy source in terms of capacity addition, but installations are not enough to meet the 2030 target
New solar PV additions in Germany in the month of April 2025 totaled 838.5 MW, representing an annual decline of over 37% from 1.34 GW a year ago, according to Bundesnetzagentur or the Federal Network Agency.
The installations rose by close to 5% month-on-month from 802.2 MW in March 2025, which is a revised number compared to the 787 MW the agency declared previously, making it the 2nd consecutive quarter of solar installations under 1 GW (see Germany’s March 2025 Solar Additions Drop Sharply To 787 MW).
While the rooftop PV segment added 449.4 MW, 53.4 MW was contributed by balcony solar systems. Another 245.6 MW represents capacity added by 151 ground-mounted solar power plants.
At the end of April 2025, Germany’s total installed solar PV capacity reached 104.85 GW, comprising 4.65 GW added during the initial 4 months of the year which is lower than over 5 GW installed during 4M 2024.
While Germany’s monthly solar installations are nowhere near the 1.62 GW it requires to meet the 215 GW cumulative target by 2030, it is still far ahead of other renewable energy technologies. Onshore wind additions in April this year added up to 316.1 MW, while new biomass capacity was 11.9 MW. There have been no new registrations for offshore wind energy during the period.
