Generation, solar thermal

Solar thermal power generation nationwide has been 3.7% higher than in 2020, but it is 12% lower than the maximum generation recorded in 2017.

Evolution of solar thermal generation

Andalusia and Extremadura are the regions with the highest solar thermal generation, both of them covering 83.5% of this generation.

The highest generation was recorded in the month of July. The monthly maximum is 4.1% higher than that of 2020, although it is 3.5% lower than that of 2018. The seasonality of this technology is similar to that of photovoltaic, although its daily electricity generation is distributed more evenly throughout the day, thanks to the ability of these plants to store part of the heat they obtain from the sun's rays and use it in later hours.
