Solar thermal generation was 13.9 % higher than in 2022.

Evolution of solar thermal generation

Annual share of solar thermal generation in total generation

Andalusia and Extremadura are the autonomous communities with the highest solar thermal generation, together accounting for 83.4 % of this generation.

Solar thermal generation in 2023

Solar thermal power generation of each autonomous community as a proportion of the national solar thermal power generation

July was the month with the highest generation, with a value 15.1 %, higher than the previous annual high, which was recorded July 2022. Compared to previous years, it is 13.6 % lower than the all-time high, recorded in 2015. The seasonality of this technology is similar to that of photovoltaic, although its daily production is distributed more evenly throughout the day due to the capacity of these power stations to store part of the heat they obtain from the Sun and use it in later hours.
