IEA SHC’s 2025 edition of Solar Heat Worldwide highlights top solar heat markets globally. In 2024, China led the global market for industrial solar heat, while the Netherlands recorded the highest increase in newly installed solar district heating capacity in Europe. Germany topped the charts for newly installed hybrid photovoltaic-thermal (PVT) collectors. The newly released Solar Heat Worldwide 2025 report presents the latest data across key applications of solar heating and cooling, including residential water heating, district heating, process heat, solar cooling, and drying.
“The 17.8 GW of new solar heat capacity installed last year once again demonstrates the broad appeal of this technology – serving building owners, agricultural businesses, hotels and industrial users alike. Its versatility and adaptability underscore its vital role in advancing climate neutrality”, noted Lucio Mesquita, Chair of the IEA Solar Heating and Cooling (IEA SHC) Programme that publishes Solar Heat Worldwide annually.
