Annotation of standard text IEC 60904-5-ed.2.1+Amd.1-CSV :
IEC 60904-5:2011+AMD1:2022 describes the preferred method for determining the equivalent cell temperature (ECT) of PV devices (cells, modules and arrays of one type of module), for the purposes of comparing their thermal characteristics, determining NOCT (nominal operating cell temperature) and translating measured I-V characteristics to other temperatures. The main technical changes with regard to the previous edition are as follows: - added method on how to extract the input parameters; - rewritten method on how to calculate ECT; - reworked formulae to be in line with IEC 60891. LIEC 60904-5:2011+AMD1:2022 decrit la methode preferentielle pour determiner la temperature de cellule equivalente (ECT) des dispositifs photovoltaiques (cellules, modules et champs dun type de module), dans les buts de comparer leurs caracteristiques thermiques, de determiner leur NOCT (temperature nominale dutilisation des cellules) et de transposer les caracteristiques I-V mesurees a dautres temperatures que celles de leur mesure. Les principaux changements techniques par rapport a ledition precedente sont les suivants: - ajout dune methode explicitant comment extraire les parametres dentree; - reecriture de la methode explicitant comment calculer ECT; - travail sur les formules pour quelles soient coherentes avec lIEC 60891.
