Photovoltaic devices - Part 2: Requirements for photovoltaic reference devices

IEC 60904-2:2023 gives requirements for the classification, selection, packaging, marking, calibration and care of photovoltaic reference devices. This document applies to photovoltaic (PV) reference devices that are used to measure the irradiance of natural or simulated sunlight for the purpose of quantifying the electrical performance of photovoltaic devices (cells, modules and arrays). It does not cover photovoltaic reference devices for use under concentrated sunlight. This fourth edition cancels and replaces the third edition published in 2015. This edition includes the following significant technical changes with respect to the previous edition: a) added calibration procedures for calibrating PV devices at maximum power by extending the respective Clauses 12 and 13; b) revised requirements for mandatory measurement of spectral responsivity, temperature coefficients and linearity, depending on usage and allowing some measurements on equivalent devices; c) revised requirements for built-in shunt resistor; d) added requirements for traceability of calibration explicitly.

Dispositifs photovoltaïques - Partie 2: Exigences applicables aux dispositifs photovoltaïques de référence

L'IEC 60904-2:2023 donne les exigences relatives à la classification, à la sélection, au conditionnement, au marquage, à l’étalonnage et aux précautions d’utilisation des dispositifs photovoltaïques de référence. Le présent document s’applique aux dispositifs photovoltaïques (PV) de référence utilisés pour mesurer l’irradiance de la lumière solaire naturelle ou simulée afin de quantifier les performances électriques des dispositifs PV (cellules, modules et panneaux). Il ne couvre pas les dispositifs photovoltaïques de référence pour une utilisation sous éclairement solaire concentré. Cette quatrième édition annule et remplace la troisième édition parue en 2015. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a) ajout de procédures d’étalonnage des dispositifs PV à la puissance maximale en développant les Articles 12 et 13) correspondants; b) révision des exigences applicables au mesurage obligatoire de la sensibilité spectrale, des coefficients de température et de la linéarité, en fonction de l’usage et en permettant certains mesurages sur des dispositifs équivalents; c) révision des exigences applicables aux résistances de shunt intégrées; d) ajout d’exigences pour la traçabilité de l’étalonnage de manière explicite.

Fotonapetostne naprave - 2. del: Zahteve za referenčne sončne naprave

Standard IEC 60904-2:2023 podaja zahteve za klasifikacijo, izbiro, pakiranje, označevanje, umerjanje in oskrbo referenčnih sončnih naprav. Ta dokument se uporablja za referenčne sončne naprave, ki se uporabljajo za merjenje obsevanja naravne ali simulirane sončne svetlobe z namenom količinske opredelitve električne učinkovitosti fotonapetostnih (PV) naprav (celic, modulov in polj). Ne zajema referenčnih sončnih naprav za uporabo pod koncentrirano sončno svetlobo. Četrta izdaja razveljavlja in nadomešča tretjo izdajo, objavljeno leta 2015. Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) z razširitvijo točk 12 in 13 so bili dodani postopki za umerjanje fotonapetostnih naprav pri največji moči;
b) zahteve za obvezno merjenje spektralne odzivnosti, temperaturnih koeficientov in linearnosti so bile spremenjene glede na uporabo, pri čemer je bilo nekaj meritev opravljenih na enakovrednih napravah;
c) zahteve za vgrajene odvodne upore so bile spremenjene;
d) dodane so bile zahteve izrecno za sledljivost umerjanja.

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
