IEA SHC Task 54: Solar Thermal Cost Reductions

Submitted by Baerbel Epp on November 26, 2017
Linz workshop Task 54The objective of IEA SHC Task 54 is to reduce the purchase price of solar thermal systems by up to 40 % across the entire value chain. To achieve this, the project partners have been evaluating technical and non-technical cost-saving potential, with low-cost materials, such as polymers, and production technologies bound to play an important role. At an early October workshop in Linz, Austria, about 50 project partners and guests discussed cost reductions made possible by new distribution channels, digital solutions and systems thinking approaches.

IEA SHC: Task 56 Kick-Off Meeting on Building Integrated Solar

Submitted by Baerbel Epp on March 30, 2016
Norway AventaAlmost 30 experts from 25 partner organisations met in Bolzano, Italy, on 21 and 22 March for the kick-off meeting of IEA SHC Task 56, Building Integrated Solar Envelope Systems for HVAC and Lighting. The overall goal of the task is to find out “why some ways of solar integration do work, while others don’t,” as the Task Operating Agent and Coordinator of the Sustainable Heating and Cooling Systems research team at Italian institute EURAC, Roberto Fedrizzi, put it – and, of course, to find measures to improve solar technology integration into façades and roofs. The photo shows a residential home in Stavern, southern Norway, where 7 m2 of solar collectors have been integrated into window frames in the south-facing facade, contributing to both domestic hot water preparation and space heating.

Austria: One World Solar Collector Receives Solar Keymark

Submitted by Baerbel Epp on November 20, 2015
SunlumoThe One World Solar Collector developed by Austrian company Sunlumo finally received a Solar Keymark certificate in October 2015 (see the attached PDF). This is a milestone in the long design and development process, which started in 2009. “We designed a completely new collector model optimising weight, performance, logistics and raw materials,” Robert Buchinger (left), Managing Director of Sunlumo, says about the long term R&D project. The photo, which was taken at machinery supplier Fill’s booth at the 2014 edition of Fakuma, the international trade fair for plastics processing, in Germany, shows Buchinger and Wilhelm Rupertsberger, Head of Competence Center Polymer Technology at FilI, holding up the pilot collector with a gross collector area of 0.95 m² and a weight of only 8.1 kg. Sunlumo is looking for investors who want to purchase a complete production line as well as the license and produce the polymer collector locally. The One World Solar Collector is the third 100 % polymer collector with a Solar Keymark certificate. The other two are Eco Flare 3M by Israeli manufacturer Magen Eco Energy and a collector from Norway’s Aventa.

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. 
 

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.

Norway: Infrared Welding Machine Completes Automated Polymer Absorber Production

Submitted by Baerbel Epp on February 2, 2013

Aventa’s automated production line for polymer-based solar thermal absorbers is now complete. Austrian machinery supplier FILL has just delivered the last component to the Norwegian company: an infrared welding machine, which is used to join the extruded absorber sheets to the injection-moulded end caps and form a 100 % polymer absorber. According to a press release from the middle of January, the machine has an annual capacity of 40,000 m2 of collector area per shift.
