Germany’s solar power generation approaches record high

Germany's solar power generation is on track to achieve a record high, according to recent data. By September 27, solar energy had already generated 90.2 terawatt-hours, surpassing the 90 terawatt-hours produced throughout all of 2025, according to the German Solar Association (BSW-Solar). This progress is attributed to an unusually sunny spell and the ongoing expansion of photovoltaic capacity.

In comparison, 20 years ago, solar power contributed a mere 2.2 terawatt-hours annually. Carsten Kornig, managing director of BSW-Solar, emphasized that photovoltaics has evolved from a niche technology into a fundamental component of Germany's electricity supply. The approaching record signifies a significant milestone in the country's energy transition, bringing advantages such as lower electricity costs, reduced reliance on energy imports, and diminished climate-related damage.

One terawatt-hour equals one billion kilowatt-hours, with an electricity output of 100 terawatt-hours being an immense quantity of energy. For context, Hamburg consumed 10.7 terawatt-hours of electricity last year, while the average German household uses between 2,000 and 4,000 kilowatt-hours annually. As of June 2026, renewable sources, including photovoltaics, accounted for 59.1% of all domestic electricity generation in Germany.

Photovoltaics alone contributed 17.8% to total domestic electricity generation, positioning it as the third-largest electricity source after wind power and coal.
