Germany achieved a new solar power record of 90.2 terawatt hours by the end of September

According to industry information, Germany has reached a new solar record: As of Sunday, 90.2 terawatt hours of solar power had already been generated this year, more than in the entire year of 2025, as the Federal Solar Industry Association (BSW-Solar) announced in Berlin. The association referred to data from the Fraunhofer Institute for Solar Energy Systems ISE. In the entire previous year, 90.0 terawatt hours of solar power were generated.

“The sun has already supplied more electricity this year than in the whole of last year - and that in September,” explained BSW Solar Managing Director Carsten Körnig. "This is news that Germany can be proud of."

The association declared September 27th “Solar Day” because of the new record. According to BSW-Solar, both “unusually many hours of sunshine and the continuous expansion of photovoltaics” contributed to the record. This emerges from data from the German Weather Service and the Federal Network Agency.

The federal association recently announced that the legally set expansion target for solar energy for 2026 had already been achieved. “The nationwide installed photovoltaic output exceeded the 128 gigawatt peak (GWp) mark in August,” said BSW-Solar. However, because of Federal Economics Minister Katherina Reiche's energy policy, the association considers the achievement of further milestones to be at risk.

According to the information, more than six million solar power systems are now installed in Germany. They contributed around a fifth of Germany's net electricity generation last year. “Anyone who concludes that the solar expansion is now running on its own is wrong,” warned BSW boss Körnig. “Around 87 gigawatts of solar capacity must be added by 2030. To achieve this, the annual expansion rate must increase instead of decreasing.”
