Germany added 4.3 GW of solar capacity in the third quarter (Q3) of 2025, a 7.8% year-over-year (YoY) increase from 4 GW, according to data from the Federal Network Agency (Bundesnetzagentur).

The country added a total of 11.8 GW in the first nine months of 2025.

Mercom reported that Germany installed 3 GW of solar power in Q2 2025. However, Bundesnetzagentur later revised this figure to 3.3 GW.

The country added 1,465 MW of solar capacity in July, 1,936 MW in August, and 920 MW in September.

The majority of the installations were located in Ausschließliche Wirtschaftszone, Baden-Württemberg, Bayern, Berlin, and Brandenburg.

The country’s cumulative solar capacity reached 112.25 GW with the recent addition.

According to Germany’s Renewable Energy Sources Act program, the cumulative solar installation target by the end of 2026 is 128 GW, 172 GW by 2028, and 215 GW by 2030.

Germany awarded 486 MW of solar plus storage projects under its innovation auction. The successful bid prices ranged from €0.0479 (~$0.056)/kWh to €0.0559 (~$0.065)/kWh, with an average volume-weighted award price of €0.0531(~$0.062)/kWh. Bundesnetzagentur said this price is lower than the ceiling price of €0.09 (~$0.1)/kWh and the previous auction’s average volume-weighted awarded price of €0.0615 (~$0.072)/kWh.

In August this year, Bundesnetzagentur awarded 2,271 MW of ground-mounted solar projects categorized under the ‘first segment,’ which are installations located on structures that are neither buildings nor noise barriers. The awarded prices ranged between €0.0400 (~$0.0468)/kWh and €0.0626 (~$0.0732)/kWh, with the average volume-weighted price settling at €0.0484(~$0.0566)/kWh.

In July, the Federal Network Agency awarded 255 MW of solar projects on buildings and noise barriers in the previous tender round. The awarded tariffs ranged from €0.069 (~$0.0745)/kWh to €0.1038 (~$0.1121)/kWh. The volume-weighted average award value came in at €0.0922 (~$0.0996)/kWh.

In April, Germany awarded 2,638 MW of ground-mounted solar projects. Awarded prices ranged between €0.0399 (~$0.0457)/kWh and €0.0488 (~$0.0559)/kWh, with the average volume-weighted price settling at €0.0466(~$0.0534)/kWh.
