Analysis
In 2025, installed solar energy capacity in Austria stood at 10.3 gigawatts. That is the highest value across all 26 years on record.
Compared with earlier readings it is up 15.7% on the previous year and up 993.1% over ten years.
Over the whole period, installed solar energy capacity in Austria peaked at 10.3 gigawatts in 2025 and was at its lowest, 0.005 gigawatts, in 2000.
That places Austria 24th out of 218 countries with data for 2025, putting it in the top quarter.
The series is highly variable year to year, so single readings are best treated with caution.
