1 Norms & Certificates Roland Valckenborg TKI Urban Energy, 8 th June 2018

2 Why a Solar Energy Application Centre (SEAC)? Implementation of the Paris goals for the Netherlands via klimaat akkoord. An energy transition is mandatory! PV can supply 25 to 30% of the total energy demand [refs: ] This corresponds to roughly 230 GWp PV-capacity to be installed before This needs a lot of area! Where do we install all this PV?

3 Solar area in the Netherlands (2050) Agriculture Wood Resi- Industrial Trafdential fic Yellow circles will be PV-areas Other Nature Offshore Inland water Recreation Exclusive Economic Zone of the North Sea Please note! : many applications still on low TRL A lot of innovative research & development needed.

4 Norms in relation to Energy Transition Energy transition will be mainly about effective area usage by double-function. So what do we need? PV-panels, ST-collector, PVT, vessels, control systems, Solar(Renewable) Energy Components batteries, inverters, heat pumps, as part of Efficient Systems and Applications should be Performance calculation methods, Normative requirements, Integrated Logical and Safe into our Qualified Installers (elektronic, heat, building contractors, ) Built Environment Infrastructural specific (noise barriers, roads, dikes, ) Buildings: more general approach possible (NEN E/W)

5 Outline presentation 1. Norms for components (product level): Solar PV-panels Solar Thermal collectors Combined: PVT 2. Performance of components 3. Performance of systems 4. Installer 5. Integration aspects Focus on NEN7250, because it is a general and helpful tool for building integration 6. Building Energy Performance

6 Remark / Disclaimer SEAC has focus on co-development with industrial parties that are in developing stage TRL 3 till TRL 7. Whenever a project partner reaches TRL 8 (typical installation at launching customer) or at TRL 9 (=full commercial), an accredited institute should be approached. Therefore some knowledge gaps might be in this presentation. Feedback welcome!

7 Norms PV PV module certification design safety qualification thin-film IEC IEC crystaline IEC IEC Do not underestimate the number of tests to comply; see next slide.

8 Overview of tests TF: csi: 61215

9 Example: datasheet thin-film

10 Example I: datasheet crystalline

11 Example II: datasheet crystalline

12 Solar Thermal Performance Not possible to label by one performance indicator, like PV A minimum of 3 parameters are needed to represent the collector curve

13 Solar Thermal norm ISO 9806 (or EN 12975) Two methods allowed:

14 Example datasheet Solar Thermal

15 PVT No specific norm from the IEC Must comply with norms for both PV-panels as well as Solar Thermal collectors Solar Keymark defined an Annex J Again: do not underestimate the number of actual tests to comply to both (PV) and 9806 (thermal). See next slide of the German project PVT Norm that is the practical implementation for PFT-panel testing.

18 PV-panel Energy Yield specification HTC High Temp. Condition LTC LIC Low Temp. Condition Low Irradiance Condition STC Standard Test Condition NOCTNominal Operating Cell Temp.

19 Example PV-panel annual yield From datasheet (Ertex VSG-L 225Wp), measured according to new IEC : Easy step towards yield per matrix bin (either by modeling or by outdoor measurements): Finally the weighted sum of all bins gives the annual yield

20 Trend PV-panel energy yield rating IEC Year Important topics G POA - T MOD power matrix generation AOI and spectral effects Energy rating of PV modules Standard reference climatic profiles

21 Trend PV-system annual yield measurements (IEC 61724) IEC 61724:1998 Photovoltaic system performance monitoring Guidelines for measurement, data exchange and analysis includes: Accuracy of measurement equipment Parameters to be measured Definition of specific yield [kwh/kwp] Definition of Performance Ratio [%] Everything for the AC-output of the total system (incl. BOS and power electronics). SEAC offers also DC-version of this norm as PV-panel specification of outdoor measurements. Norm updated in 2017 with: classification in 3 classes of accuracy (A/B/C) more specific on equipment

22 Solar Thermal Energy Yield calculation methods / specification Methods that author knows: Rekenmodel uit NEN 7120 Energieprestatie gebouwen Bepalingsmethode met paragraaf 14.5 voor ruimteverwarming en bijlage G voor tapwater Rekenmethode uit het ISSO zonne-energiehandboek, bijlage M NPR 7976 Bepaling van de energetische opbrengst van zonneboilers voor huishoudelijk gebruik op basis van NL ref.omstandigheden Annual collector performance according to EN (as part of Solar KeyMark) ISDE-subsidy for solar thermal collectors based on jaaropbrengst per : SOLCAL-method, based on FprEN :2017 annex F Available software: TRNSYS, Polysun, SOLCAL App (

23 Trend: Performance contracts PV systems are relatively the easiest for annual yield calculations. Therefore a contract on guaranteed [kwh/yr] is already possible, and more will follow. Solar thermal (& PVT) systems are more complicated to calculate annual yield much more depending on application Author not aware of an annual thermal yield contract option. Energy performance contracts of buildings do exist, as part of Design, Build, Finance, Maintain, (Operate) = DBFM(O).

24 Installer in NL: content Content superb! THE reference book For each installer Both PV and Thermal Certificates, Etc Next slide

26 Integration aspects For Infrastructural Integration: very broad application area: landfills, noise barriers, floating PV, solar roads, etc... Finding (and co-developing) relevant norms is part of projects of SEAC. In case of questions, author can give contact to specific project. For Building Integration, there is a well defined European context. For the Netherlands there is a clear norm.

27 Building codes: world -> EU -> NL World: IEA PVPS Task 15C has ambition to report a global overview of building codes regarding solar energy system integrations. Expected mid June Europe: draft Technical Report prtr "Solar energy systems for roofs: Requirements for structural connections based on input from translated Dutch standard (NEN 7250) and from the French standard (NF P78-116) Europe: (CENELEC) EN 50583:2016 'Photovoltaics In Buildings based on CPR 305/2011 and LVD2006/95/EC Netherlands: bouwbesluit & NEN 7250

33 NEN 7250 Feedback welcome Permanent NEN commission developed this norm and maintains it. Since publication a wish list of suggestion is collected of: Clarifications Modifications Extensions These are discussed both internal and with external experts. For the near future an update is planned. Therefore, please provide feedback to me, or directly to chairman: c.vandermeijden@bda.nl

34 Building Energy Performance of Renovation (in EU and NL) Requirements This page is unfortunately left blank. Just a few EU-countries have requirements for deep-renovation projects.

35 Building Energy Performance of Renovation Calculation Method in NL Energie-Index (EI) volgens rekenmethode NEN 7120 EI determines energy label Requirement to have this label when selling the house

36 Building Energy Performance of New Built (in Europe and NL) EU: Energy Performance Building Directive (EPBD) 2002/91/EC Every EU-country derived its own local laws from this directive NL from 1995 defined the EPC EPC-requirement for residential & utility EPC = Energie Prestatie Coefficient
