Germany: Solar process heat 50 to 80% cheaper than gas-based alternatives
Solar process heat using concentrating collectors has proven to be economically viable in Germany. According to a recent study by the German Fraunhofer Institute for Solar Energy Systems ISE, presented by Dr. Shahab Rohani at the Symposium Zukunft Wärme (Future Heat), payback periods range from 3.4 to 7 years, depending …
Solar thermal – a growing market spotlighted at Intersolar Mexico
Mexico’s solar heat market is gaining impressive traction. In 2023, the market grew by 5%, ranking sixth globally, while mature markets like Germany shrank by 47 %. This upward trend continued in 2024 with newly installed collector area growing by almost 10% to 505,711 m2 (354 MW) according to market …
Brazil adds 1.4 GW of solar collectors, surging to global No. 2 in 2024
The Brazilian solar thermal market continues to grow – by a remarkable 11% in 2024. This pushes Brazil ahead of Turkey, making it the second largest market in the world after China. In 2024, 2 million m2 were added, corresponding to 1.4 GW. The drivers in the market are the …
Accelerating solar fuel discovery guided by AI-driven autonomous lab
A new research group within the IEA Solar Heating and Cooling Programme is focusing on the development of solar-driven processes and reactors, for example to produce solar hydrogen or convert CO2 and N2 to ammonia. The group is called Task 72 – Solar photo reactors for the generation of fuels …
Australia’s strong role in the IEA SHC global solar heat collaboration
Australia remains a highly active participant in the IEA Solar Heating and Cooling Programme. Over the past three years, Professor Robert Taylor from the University of New South Wales has co-chaired Task 69, focused on Solar Hot Water for 2030. Continuing Australia’s active involvement, Doug Smith, CEO of Coolsheet PVT …
The Canadian solar market declined from its 2023 peak but still outpaced 2022
Solar air heating was once again the main application for the solar thermal industry in Canada. 90 % of the newly installed collector area in 2024 was glazed and unglazed air collectors. Good funding conditions in the province of Quebec drove the market. However, the record year 2023 with 28,054 …
44 MW in Kosovo, 27 MW in Serbia: solar district heating projects gain momentum
The realization of two huge solar district heating projects in the Balkans is progressing. The pre-qualification tender for a 44 MW collector field with seasonal storage in Pristina, Kosovo, ended on 11 April 2025. The second site is Novi Sad – a town in Serbia, where a 27 MW collector …
Mapping the global thermosiphon market: insights from eight world regions
Thermosiphon systems account for more than half of the total installed solar thermal capacity worldwide (status at the end of 2022), but little is published about them. The scientists from Task 69 Solar Hot Water for 2030 have closed that gap. They carried out a survey among manufacturers of thermosiphon …
