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.
