Fraunhofer Institute for Solar Energy Systems ISE analysis showed that photovoltaics had a major role in Germany’s public electricity generation in 2025. Solar output had risen by 21% year on year to about 87 TWh. Of this generation, around 71 TWh had been supplied to the public grid, while 16.9 TWh had been consumed directly by system operators. Installed photovoltaic capacity had reached 116.8 GW (DC) by the end of the year, with about 16.2 GW (DC) added in 2025, but additions had remained below the level required to meet future targets. Higher self-consumption rates and less optimal system orientations had reduced grid-fed volumes despite higher generation. Photovoltaics had overtaken lignite for the first time in net public electricity generation, while wind power had remained the largest source at 132 TWh and total renewable generation had stayed below the 346 TWh target set for 2025.
