Task 39

IEA SHC: Industry Invited to Join Research Community for Lower Solar Heat Costs

Submitted by Baerbel Epp on October 12, 2015
TASK 54Driving down the costs of solar thermal systems is not only about cheaper collector production. In fact, post-production processes, such as sales, installation and maintenance account for up to 50 % of the price the end customer will have to pay. The new IEA SHC Task 54, Price Reduction of Solar Thermal Systems, wants to investigate those factors and find ways to reduce system costs. The kick-off meeting on 21 to 22 October will be hosted by Fraunhofer ISE in Freiburg, Germany. Researchers and industry representatives from all over the world have been invited to participate. The task spans over three years and includes on average two two-day experts meetings per year. 
 

Germany: Polymer Collector Design for EUR 25 Production

Submitted by Baerbel Epp on March 31, 2015
Polymer CollectorsDuring project ExKoll, scientists at the Fraunhofer Institute for Solar Energy Systems, Fraunhofer ISE, have developed a new low-cost design for solar thermal collectors. The entire production of an 80 cm x 160 cm collector made of polypropylene (PP, drawing on the right) with an operating temperature resistance of up to 100 °C would amount to a mere EUR 25. A design which includes an absorber made of polyphenylene sulfide (PPS, left drawing) and which can resist operation temperatures of up to 250 °C would have production costs of around EUR 45 per panel. The following text was based on a presentation held at a workshop of Task 39, Polymeric Materials for Solar Thermal Applications, in Israel in April 2014. ExKoll ended in December 2014, Task 39 of the IEA’s Solar Heating and Cooling Programme did so in October 2014. A new task, which will have the focus on cost reduction potential in collector production and will be led by Michael Köhl from Fraunhofer ISE, is scheduled for the second half of 2015.

Norway: Research Community Visits Estate Built with Polymer Collectors

Submitted by Baerbel Epp on November 2, 2014
StenbratliaNorwegian collector manufacturer Aventa and the University of Oslo’s Department of Physics jointly hosted two meetings in the middle of October: The meeting of Task 39 (Polymeric Materials for Solar Thermal Applications) of the International Energy Agency’s Solar Heating and Cooling programme (IEA SHC), as well as the meeting of the EU’s SCOOP (Solar Collectors made Of Polymers) project. Both research programmes focus on the use of polymeric materials in solar thermal applications and are headed by Michael Köhl, researcher at the German Fraunhofer Institute for Solar Energy Systems, Fraunhofer ISE. The photo shows the attendants of the research meeting while they were visiting Stenbråtlia: Architect Hans Dahl (middle), Prof John Rekstad, CEO of Aventa (far left) and Dr Michaela Meir, Head of R&D at Aventa (far right). Stenbråtlia consists of 34 terraced houses built according to the so-called passive house standard and equipped with roof-integrated polymer collectors from Aventa.

Germany: Task 39 Showcases Solar Collectors Made of Polymers

Submitted by Baerbel Epp on October 5, 2013

An exhibition taking place as part of the International Conference on Solar Heating and Cooling (SHC) 2013 between 23 and 25 September 2013 unveiled how solar collectors manufactured from plastic materials may look like in the future. Under the motto Efficiency and Design, the exhibits provided an insight into research trends and product innovations for solar thermal applications. The exhibition was organised by a working group of Task 39, a sub-task of the International Energy Agency’s Solar Heating and Cooling Programme, IEA SHC.
