– 32.1% The decrease of the solar thermal market in the European Union between 2023 and 2024
Slowdown contagion spread to the main European Union solar thermal markets,
including the Greek market, said to be its most stalwart, and depressed 2024
sales. The previous year’s 21.1% drop in collector surface worsened to 32.1%. In 2024, just under 1.3 million m² of collectors were installed – almost 606 000 m²
less than in 2023. Many mainly residential segment-related factors contributed
to this 100% European technology’s ill fortunes. Examples are the Europe-wide
sluggish heating and construction markets, the dilution and suspension of several
energy renovation aid policies, not to mention the sector’s struggle to compete
with the current rush to adopt photovoltaic self-consumption. Announcements of new mega-projects in a number of European countries mean that the very large installation segment is taking shape.
