Photovoltaic devices - Part 10: Methods of linear dependence and linearity measurements

IEC 60904-10:2020 describes the procedures used to measure the dependence of any electrical parameter (Y) of a photovoltaic (PV) device with respect to a test parameter (X) and to determine the degree at which this dependence is close to an ideal linear (straight-line) function. It also gives guidance on how to consider deviations from the ideal linear dependence and in general on how to deal with non-linearities of PV device electrical parameters. This third edition cancels and replaces the second edition published in 2009. This edition includes the following significant technical changes with respect to the previous edition: a. Modification of title. b. Inclusion of an Introduction explanatory of the changes and the reasoning behind them. c. Inclusion of a new Clause Terms and Definitions (Clause 3), with distinction between generic linear dependence and linear dependence of short-circuit current versus irradiance (linearity). d. Explicit definition of equivalent sample (Clause 4). e. Technical revision of the apparatus (Clause 5), of the measurement procedures (Clause 6 to Clause 8) and of the data analysis (Clause 9), with separation of the data analysis for a generic linear dependence from the data analysis specific to linearity (i.e. short-circuit current dependence on irradiance) assessment. Additionally, inclusion of impact of spectral effects on both linearity and linear dependence assessment. f. Introduction of specific data analysis for two-lamp method, making it fully quantitative. Addition of extended version called N-lamp method. g. Modification of the linearity assessment criterion with inclusion of a formula that can be used to correct the irradiance reading of a PV reference device for non-linearity of its short-circuit current versus irradiance. A linearity factor is specifically newly defined for this purpose. h. Revision of the requirements for the report (Clause 10) in order to improve clearness about what information is always necessary and what is dependent on the procedure actually followed to measure the linear dependence, including the type of dependence measured (generic or linearity).

Photovoltaische Einrichtungen - Teil 10: Methoden zur Messung der linearen Abhängigkeit und Linearität

Dispositifs photovoltaïques - Partie 10: Méthodes de mesure de la dépendance linéaire et de la linéarité

l’IEC 60904-10:2020 décrit les procédures utilisées pour mesurer la dépendance de tout paramètre électrique (Y) d’un dispositif photovoltaïque (PV) par rapport à un paramètre d’essai (X) et pour déterminer le degré de proximité de la dépendance par rapport à une fonction linéaire idéale (ligne droite). Elle fournit également des recommandations relatives à la prise en considération des écarts par rapport à la dépendance linéaire idéale et, de façon générale, sur le traitement des non-linéarités des paramètres électriques d’un dispositif PV. Cette troisième édition annule et remplace la deuxième édition parue en 2009. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a. Modification du titre. b. Ajout d’une Introduction qui explique les modifications apportées et les raisons de ces modifications. c. Ajout d’un nouvel Article Termes et définitions (Article 3) qui fait la distinction entre la dépendance linéaire générique et la dépendance linéaire de courant de court-circuit en fonction de l’éclairement (linéarité). d. Définition explicite de l’échantillon équivalent (Article 4). e. Révision technique de l’équipement (Article 5), des procédures de mesure (Article 6 à Article 8) et de l’analyse des données (Article 9), avec distinction entre analyse des données relative à une dépendance linéaire générique et analyse des données spécifique à l’évaluation de la linéarité (c’est-à-dire la dépendance du courant de court-circuit sur l’éclairement). De plus, ajout de l’impact des effets spectraux sur l’évaluation de la linéarité et de la dépendance linéaire. f. Introduction d’une analyse de données spécifique à la méthode à deux lampes, rendant celle-ci entièrement quantitative. Ajout d’une version étendue appelée méthode à N lampes. g. Modification du critère d’évaluation de la linéarité avec ajout d’une formule qui peut être appliquée pour corriger le relevé d’éclairement d’un dispositif PV de référence pour la non‑linéarité de son courant de court-circuit en fonction de l’éclairement. Un facteur de linéarité spécifique est nouvellement défini dans ce but. h. Révision des exigences relatives au rapport (Article 10) afin de préciser les informations qui sont toujours nécessaires et ce qui dépend de la procédure réellement suivie pour mesurer la dépendance linéaire, y compris le type de dépendance mesuré (générique ou linéarité).
