  1. FraunhoferInstitutEfOr Solar EnergYSystemS ISE Deficits in the Solar Keymark certification scheme for SAHC • Solar Keymark Working Group SAHC: • Korbinian (Chair), Jaime Fernández, Patrick Ollas, Katharina Meyer www.collectortest.com www.ise.fraunhofer.de 1

  2. Deficits in the Solar Keymark certification for SAHC • EN ISO 9806:2013: • No efficiency curve for the operation mode „open-to-ambient“, just efficiency points at different mass flow rates/wind speed rates • Details for the boundary conditions for testing SAHC are with gaps/unclear • Certification Scheme: • No default data sheet to present the mass flow dependend three efficiency points • Family defintion can be interpreted towards its technical limits (not very well validated)

  3. Next steps • Short term: • 1) Develop a default data sheet which can handle the curve, use existing adoptions from SP/CENER/ISE, working group presents one at next meeting: • 2) Standard will be published 2017 in revision with clearification on boundary conditions for testing • _____ • Mid term: • 1) Develop a efficiency curve, which improves the transparency in comparrison to other technologies and within the methodology of Solar Keymark • 2) Evaluate this method • 3) Apply this method on respective products • 4) Use the exisiting data sheet, which then is fitting
