It is well worth arriving in Freiburg, Germany, a day early for EuroSun2026! On Monday, 14 September, a series of expert meetings for different Tasks of the IEA Solar Heating […]
In June 2026, the German renewable energy news journal Solarthemen published its 600th issue, marking 30 years of independent journalism covering the energy transition. Founders Guido Bröer and Andreas Witt […]
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 […]
PVT collectors that use air as the working fluid are being evaluated within IEA SHC Task 73 entitled PVT Heating Systems. They can preheat ventilation air in buildings while producing […]
The number of experienced suppliers in the solar heat for industrial processes (SHIP) sector continues to grow. By the end of 2025, 23 companies had installed more than ten SHIP […]
PVT collectors can make highly efficient heat sources for heat pumps, but they also create special technical challenges. Unlike conventional heat sources such as ambient air or shallow geothermal energy, […]
Karl-Anders Weiß has spent the past three years intensively working on the life cycle and cost assessment of alternative heating technologies. The researcher from the German institute Fraunhofer ISE has […]
The combination of PV module and thermal absorber – known as PVT – is available in many different designs. „There is no universally optimal PVT collector; the best solution is […]
A solar collector can do more than just generate heat. As a hybrid collector, it can simultaneously produce fuel and electricity as well. Scientists from IEA SHC Task 72 are […]
The European PVT collector industry is undergoing a significant transformation, with manufacturers focusing on increasing production efficiency, improving quality assurance, and reducing dependence on imported components, particularly from China. These […]
