Item Accelerated aging test of solar reflectors according to the new AENOR standard – results of a round Robin test(American Institute of Physics Inc., 2018-11-08) Fernández-García, Aránzazu; Martínez-Arcos, Lucía; Sutter, Florian; Wette, Johannes; Sallaberry, Fabienne; Erice, Raquel; Diamantino, Teresa; Carvalho, M. João; Raccurt, Olivier; Pescheux, Anne-Claire; Imbuluzqueta, Gorka; Machado, Maider; Mancilla, Rodrigo; Richter, Christoph; SISTEMAS FOTOVOLTAICOS; Tecnalia Research & InnovationDurability tests of reflector materials for concentrating solar applications are crucial to guarantee the profitability of the plants and to ensure a proper efficiency during their lifetime. A standard including a set of five accelerated aging tests is close to be published by the Spanish standardization entity AENOR, within the sub-committee AEN/CTN 206/SC117. Under the framework of the STAGE-STE project, a Round Robin Test was organized by six partners to evaluate the comparability of results obtained in their respective laboratories after performing these durability tests. According to the results, in general a good agreement among the partners was found, with negligible to slight reflectance losses. In addition, it was noticed that the reference standard used in the reflectance measurements is of high importance. The conclusions of this work will help to improve the standard in future versions.Item Solar Thermal Collectors for Medium Temperature Applications: A Comprehensive Review and Updated Database: A Comprehensive Review and Updated Database(2016-06) Iparraguirre-Torres, Iñigo; Huidobro, Ana; Fernández-García, Aránzazu; Valenzuela, Loreto; Horta, Pedro; Sallaberry, Fabienne; Osório, Tiago; Sanz, Asier; Tecnalia Research & Innovation; SISTEMAS FOTOVOLTAICOSAlthough the technology of solar thermal collectors for medium temperature applications is not new, few collectors and commercial installations were available worldwide. Presently the sector is growing rapidly, new technologies have been developed and real installations using these technologies are already being built all around the world for different applications, especially for the generation of heat required by industrial applications. Considering the increasing number of available products and the importance of disseminating this information among system designers and end-users, a database of the available solar collectors for medium temperature applications is under development. The information has been gathered from the different collector manufacturers and suppliers and the available technical information published on the different collector models. Aiming a thorough insight into these new commercially available solutions, the database includes the most relevant technical information of the different existing collectors. This work is being done within the framework of the European project STAGE-STE (Scientific and Technological Alliance for Guaranteeing the European Excellence in Concentrating Solar Thermal Energy) (http://www.stage-ste.eu/). The information gathered will also be used within the Task 49, the working group for Solar Heat Integration in Industrial Process (SHIP) of the Solar Heating and Cooling program (SHC) by the International Energy Agency (IEA) (http://task49.iea-shc.org/).
