Photovoltaic devices - Part 3: Measurement principles for terrestrial photovoltaic (PV) solar devices with reference spectral irradiance data
IEC 60904-3:2019 is available as IEC 60904-3:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60904-3:2019 describes basic measurement principles for determining the electrical output of PV devices. The principles given in this document are designed to relate the performance rating of PV devices to a common reference terrestrial solar spectral irradiance distribution. The reference terrestrial solar spectral irradiance distribution is given in this document in order to classify solar simulators according to the spectral performance requirements contained in IEC 60904-9. The principles contained in this standard cover testing in both natural and simulated sunlight. This new edition includes the following significant technical changes with respect to the previous edition: a) all spectral data were recalculated due to some minor calculation and rounding errors in the third edition; the global spectral irradiance returned to exactly the data of the second edition; b) the angular distribution of the irradiance was clarified.

IEC 60904-3:2019 est disponible sous forme de IEC 60904-3:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 60904-3:2019 décrit des principes de mesure de base pour la détermination de la sortie électrique des dispositifs PV. Les principes indiqués dans le présent document sont prévus pour relier les caractéristiques assignées de performance des dispositifs PV à une distribution spectrale de l'éclairement solaire terrestre de référence commune. La distribution spectrale de l'éclairement solaire terrestre de référence est indiquée dans le présent document pour classifier les simulateurs solaires selon les exigences pour le fonctionnement spectral contenues dans l'IEC 60904-9. Les principes contenus dans le présent document comprennent les essais réalisés sous un éclairement solaire naturel ainsi que sous un éclairement solaire simulé. Cette nouvelle édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) nouveau calcul de toutes les données spectrales en raison de la présence d'un certain nombre d'erreurs de calcul et d'arrondi dans la troisième édition; remplacement de l'éclairement spectral global par les données exactes de la deuxième edition; b) clarification de la distribution angulaire de l'éclairement
Fotonapetostne naprave - 3. del: Postopki merjenja prizemnih fotonapetostnih (PV) sončnih naprav s podatki referenčnega spektralnega sevanja
Ta del standarda IEC 60904 se uporablja za naslednje prizemne fotonapetostne naprave:
– sončne celice z zaščitnim pokrovom ali brez njega;
– podsestave sončnih celic;
– module; in
– sisteme.
OPOMBA: Za označevanje katere koli od teh naprav se uporablja izraz »preskušanec«.
Načela iz tega dokumenta zajemajo preskušanje tako pod naravno kot simulirano sončno svetlobo. Fotonapetostna pretvorba je spektralno selektivna zaradi narave polprevodniških materialov, uporabljenih v fotonapetostnih sončnih celicah in modulih. Za primerjavo relativne učinkovitosti različnih fotonapetostnih naprav in materialov je potrebna referenčna standardna spektralna porazdelitev sončnega sevanja. Ta dokument vključuje takšno referenčno spektralno porazdelitev sončnega sevanja.
Ta dokument prav tako opisuje osnovna načela merjenja za ugotavljanje električne moči fotonapetostnih naprav. Načela v tem dokumentu so namenjena povezavi ocene učinkovitosti fotonapetostnih naprav s splošno referenčno prizemno spektralno porazdelitvijo sončnega sevanja.
Referenčna prizemna spektralna porazdelitev sončnega sevanja je v tem dokumentu podana z namenom razvrstitve sončnih simulatorjev v skladu z zahtevami glede spektralne učinkovitosti iz standarda IEC 60904-9.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60904-3 has been prepared by IEC technical committee 82: Solar
photovoltaic energy systems.
This fourth edition cancels and replaces the third edition published in 2016. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) all spectral data were recalculated due to some minor calculation and rounding errors in
the third edition; the global spectral irradiance returned to exactly the data of the second
edition;
b) the angular distribution of the irradiance was clarified.
