Concentrator photovoltaic (CPV) modules and assemblies - Design qualification and type approval
IEC 62108:2016 specifies the minimum requirements for the design qualification and type approval of concentrator photovoltaic (CPV) modules and assemblies suitable for long-term operation in general open-air climates as defined in IEC 60721-2-1. The test sequence is partially based on that specified in IEC 61215-1. The object of this test standard is to determine the electrical, mechanical, and thermal characteristics of the CPV modules and assemblies and to show that the CPV modules and assemblies are capable of withstanding prolonged exposure in climates described in the scope. This new edition includes the following main technical changes with regard to the previous one:
a) changes in outdoor exposure from 1000 h to 500 h;
b) changes in current cycling during thermal cycling test;
c) added dust ingress test;
d) eliminated thermal cycling associated with damp heat test;
e) eliminated UV exposure test.
Modules et ensembles photovoltaïques à concentration - Qualification de la conception et homologation
L'IEC 62108:2016 spécifie les exigences minimales pour la qualification de la conception et l'homologation des modules et ensembles photovoltaïques à concentration (CPV) pour une utilisation de longue durée dans les climats généraux d'air libre, comme défini dans l'IEC 60721-2-1. La séquence d'essais est partiellement issue de celle spécifiée dans l'IEC 61215-1. L'objet de la présente norme d'essai est de déterminer les caractéristiques électriques, mécaniques et thermiques des modules et ensembles CPV et de montrer que les modules et ensembles CPV peuvent supporter une exposition prolongée aux climats définis dans le domaine d'application. Cette nouvelle édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) modification de l'essai d'exposition en site naturel de 1 000 h réduites à 500 h;
b) modifications des cycles de courant pendant l'essai de cyclage thermique;
c) ajout de l'essai relatif à la pénétration de poussière;
d) suppression du cyclage thermique associé à l'essai de chaleur humide;
e) suppression de l'essai d'exposition aux UV.
