Making thermosyphon systems future-proof: market insights and durability solutions
The global network of scientists within the IEA SHC Task 69 on Solar Hot Water for 2030 has been examining thermosiphon markets worldwide from July 2022 to March 2026. They analysed technical characteristics, innovations and typical sources of error and how to avoid them. The network has now published the …
No gas needed on sunny days: Belgian parabolic trough field delivers 295 °C solar process heat
One of Central Europe’s most innovative demonstration projects for solar process heat was the destination of a technical visit offered by the German Aerospace Center (DLR) as part of the German research project ProSolNetz: the parabolic trough collector plant at Avery Dennison’s manufacturing site in Turnhout, Belgium. As Germany does …
Germany’s largest solar district heating plant starts operation in Leipzig
The new solar district heating plant in Leipzig marks another milestone for Germany’s district heating transition. With 45.6 MW the installation ranks as the fourth-largest solar district heating plant worldwide and is by far the largest in Germany.

Product overview showcases the global evolution of solar air collectors
Solar air collectors for building façades were first developed in Canada 37 years ago. Two of the industry’s pioneers are Conserval Engineering and Matrix Energy. Today, solar air collectors are installed around the world. The Renewable Heat and Power Group at CanmetENERGY–Ottawa, part of Natural Resources Canada, recently commissioned a …
IEA SHC Task 70 researchers define the future of daylight modelling
Creating high-performance lighting systems is important not only for saving energy but also for improving indoor comfort and occupant well-being. Complex fenestration systems can control daylight and solar radiation. This improves both visual comfort and indoor thermal conditions. Micro-prismatic materials are one option for optimizing fenestration systems towards low carbon …
