Germany: Process Heat Supply from Vacuum Tubes and Air Collectors on the Rise

Submitted by Baerbel Epp on April 21, 2017
Process Heat StatisticsThere is a distinct difference between the make-up of the German solar process heat segment and the country’s solar thermal market in general and it concerns the type of collectors used. One in four collectors used in solar process heat systems is an air collector, although the technology contributes only around 10 % to the total collector area newly installed each year. The same has been true for vacuum tube systems, which showed a 35 % share in solar process heat installations among approved projects in 2016 – despite an overall market share of only 9 % last year. All figures are based on statistics provided by the University of Kassel’s Institute of Thermal Engineering, which has been in charge of the research accompanying the subsidy scheme on solar process heat under the auspices of Germany’s Market Rebate Programme for Renewable Energies or MAP.
