Germany’s solar output passed its entire 2025 total by September

The 0.2 TWh margin is about 200 million kWh. The key is that the annual total was exceeded roughly three months early and the 2026 number will keep rising.

Industry and independent reports cite both unusually high sunshine and more capacity; KfW also recorded more than 11 TWh in each month from May through July.

What actually increased

Energy and capacity are different. Weather, curtailment, outages and self-consumption change how much installed solar reaches the public grid; 90.2 TWh is accumulated electricity.

Why datasets may differ

Energy-Charts adjusts exchange and ENTSO-E data with monthly statistics and can revise values. Gross generation, consumption, self-use and capacity produce different totals.

A yearly record is not hourly security

Autumn and winter low-sun periods still require wind, storage, demand response, grids and other generation.

What to check next

Year-end totals, curtailment, storage growth, hourly prices and displaced fossil generation will show how much of the extra solar was actually used.
