The solar thermal energy supply in Spain stood at 31.74 thousand gigawatt-hours in 2023. Observing the data from 2013, there has been a mix of highs and lows, with notable dips in 2018 and 2020. Nonetheless, the trend over the past five years shows resilience and growth, marked by a compound annual growth rate (CAGR) of 4.3%. The year-on-year variation from 2022 to 2023 is a positive 5.63%, suggesting recovery from previous fluctuations.

Looking ahead, forecasted data indicates consistent growth through 2028, although at a moderate pace with a 5-year CAGR of 2.4% and total growth of 12.6% over this period. This suggests a stable but gradual increase in solar thermal capacity.

Future trends to watch for:

Technological advancements improving efficiency and cost-effectiveness of solar thermal solutions.
Government policies and subsidies to promote renewable energy adoption.
Increased investment in infrastructure and grid integration for renewable sources.
