4 Summary Statement: Fully agree Mostly agree neutral Mostly disagre e Totally disagre e Main comments ISO has lost its relevance now with new ErP requirements We still need the system test procedure according to ISO for future Solar Keymark certification The existing Lneg method for calculating the ISO parameter out of ISO results is sufficient 3* 3 3* 4* 2* 3* 2* 4 5* 2 1 2* 11 1* Helsinki instead of Stockholm and Strasbourg instead of Wurzburg doesn t matter 6* 3* 6* 2 Davos should stay as an optional location for Alpine climate conditions 5* The harmonisation of LTP boundary conditions between ErP and SK is important and helpful 14 1 ISO will remain ISO still part of Keymark? Chance for adapt ErP tapping cycles??? Substitution of climate locations uncritical Additional locations optional Clear climate data sets desirable Davos is also relevant for pren Current tapping profiles unrealistic Chance for the Solar Keymark Harmonisation of boundary conditions of ErP and SK with respect to long term prediction will enhance the status of Solar Keymark certification for systems The harmonisation of the LTP boundary conditions will help to raise the relevance of the EN system certification 13*

5 Next Steps Which are the most important steps for SKN and CEN TC 312? If ISO should stay, a distinction between solar only and solar + Supplementary might be necessary Solar only could stay as it was (mainly for TSS, at the moment >90% of certificates) Solar plus supplementary might be harmonized with ErP - Only ISO for EN EN for EN Every ISO test result could be used for solar only evaluation too Two main categories for simple and for more complex systems A third one for DHW-heating useful ISO might stay as it is ISO need to be adapted to faux>0.75 EN is nearly complete EN might be completely revised or partly substituted by other standards 5

8 Conclusion Harmonization of Solar Keymark & ErP Harmonization is possible Certification of solar only systems (solar devices; SD) could stay as it is Distinction between solar only (SD) and solar plus supplementary (solar water heater; SWH) necessary Harmonized boundary conditions only for solar water heater (more complex systems) Perfect starting point to restructure, improve and harmonize EN
