Photovoltaic devices - Procedures for temperature and irradiance corrections to measured I-V characteristics

This document defines procedures to be followed for temperature and irradiance corrections to the measured I-V (current-voltage) characteristics (also known as I-V curves) of photovoltaic (PV) devices. It also defines the procedures used to determine factors relevant to these corrections. Requirements for I-V measurement of PV devices are laid down in IEC 60904-1 and its relevant subparts. The PV devices include a single solar cell with or without a protective cover, a sub-assembly of solar cells, or a module. A different set of relevant parameters for I-V curve correction applies for each type of device. The determination of temperature coefficients for a module (or subassembly of cells) may be calculated from single cell measurements, but this is not the case for the internal series resistance and curve correction factor, which should be separately measured for a module or subassembly of cells. Refer to Annex A for alternative procedures for series resistance determination. The use of I-V correction parameters are valid for the PV device for which they have been measured. Variations may occur within a production lot or the type class.

Dispositifs photovoltaïques – Procédures pour les corrections en fonction de la température et de l'éclairement à appliquer aux caractéristiques I-V mesurées

IEC 60891:2021 définit des procédures à suivre pour les corrections en fonction de la température et de l'éclairement appliquées aux caractéristiques I-V (courant-tension) mesurées (également appelées courbes I-V) des dispositifs photovoltaïques (PV). Il définit également les procédures utilisées pour déterminer les facteurs appropriés pour ces corrections. Les exigences pour le mesurage I-V des dispositifs PV sont données dans l'IEC 60904-1 et ses sous-parties applicables. 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: - ajout de recommandations concernant la procédure de correction à utiliser selon l'application; - introduction de la procédure de transposition 4 applicable aux technologies c-Si avec des coefficients de température inconnus; - introduction de différentes classifications dans les procédures existantes afin d'améliorer la précision de mesure et de réduire l'incertitude de mesure; - ajout d'une annexe informative qui présente des méthodes supplémentaires qui peuvent être utilisées pour déterminer la résistance-série.

Fotonapetostne naprave - Postopki za temperaturno in sevalno korekcijo izmerjenih karakteristik I-U

V tem dokumentu so opredeljeni postopki, ki jih je treba upoštevati za temperaturno in sevalno korekcijo izmerjenih karakteristik I-U (tok – napetost; imenovane tudi krivulje I-U) fotonapetostnih naprav. Opredeljuje tudi postopke, ki se uporabljajo za določanje pomembnih dejavnikov za to korekcijo. Zahteve za merjenje karakteristik I-U fotonapetostnih naprav so podane v standardu IEC 60904-1 in ustreznih poddelih tega standarda. Fotonapetostne naprave vključujejo enojno sončno celico z zaščitnim pokrovom ali brez njega, podsestav sončnih celic ali modul. Za vsako vrsto naprave se uporablja drugačen nabor ustreznih parametrov za korekcijo krivulje I-U. Določitev temperaturnih koeficientov za modul (ali podsestav celic) se lahko izračuna iz meritev enojne celice; vendar to ne velja za dejavnik notranje upornosti serije in korekcije krivulje, ki naj se izmeri posebej za modul oziroma podsestav celic. Za alternativne postopke za določanje upornosti serije glej dodatek A.
Parametri za korekcijo I-U se uporabljajo za fotonapetostno napravo, za katero so bili izmerjeni. Pojavijo se lahko razlike znotraj proizvodne serije ali vrste razreda.
