Concentrator photovoltaic (CPV) modules and assemblies - Design qualification and type approval

This International Standard 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 for the design qualification and type approval of flat-plate terrestrial crystalline silicon PV modules. However, some changes have been made to account for the special features of CPV receivers and modules, particularly with regard to the separation of on-site and in-lab tests, effects of tracking alignment, high current density, and rapid temperature changes, which have resulted in the formulation of some new test procedures or new requirements. The object of this test standard is to determine the electrical, mechanical, and thermal characteristics of the CPV modules and assemblies and to show, as far as possible within reasonable constraints of cost and time, that the CPV modules and assemblies are capable of withstanding prolonged exposure in climates described in the scope. The actual life of CPV modules and assemblies so qualified will depend on their design, production, environment, and the conditions under which they are operated. This standard shall be used in conjunction with the retest guidelines described in Annex B.

Modules et ensembles photovoltaïques à concentration - Qualification de la conception et homologation

IEC 62108:2022 est disponible sous forme de IEC 62108:2022 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62108:2022 spécifie les exigences minimales relatives à la qualification de la conception et l'homologation des modules et ensembles photovoltaïques à concentration (CPV - concentrator photovoltaic) pour une utilisation de longue durée dans les climats généraux d'air libre, comme cela est défini dans l'IEC 60721-2-1. Le présent document d'essai a pour objet de déterminer les caractéristiques électriques, mécaniques et thermiques des modules et ensembles CPV et de montrer, autant que possible avec des contraintes de coût et de temps raisonnables, que les modules et ensembles CPV peuvent supporter une exposition prolongée aux climats définis dans le domaine d'application.

Koncentratorski fotonapetostni (CPV) moduli in sestavi - Ocena zasnove in odobritev tipa

Ta mednarodni standard določa minimalne zahteve za oceno zasnove in odobritev tipa koncentratorskih fotonapetostnih (CPV) modulov in sestavov, primernih za dolgotrajno uporabo v običajnih okoljih na prostem, kot je opredeljeno v standardu IEC 60721-2-1. Preskusno zaporedje delno temelji na zaporedju, določenem v standardu IEC 61215-1 za oceno zasnove in odobritev tipa za ploščate prizemne fotonapetostne module iz kristalnega silicija. Vendar so bile vpeljane spremembe, ki obravnavajo posebne funkcije koncentratorskih fotonapetostnih sprejemnikov in modulov, zlasti glede ločevanja preskusov na mestu uporabe in laboratorijskih preskusov, učinkov poravnave, visoke tokovne gostote in hitrih temperaturnih sprememb, na podlagi katerih so bili pripravljeni nekateri novi preskusni postopki ali nove zahteve.
Namen tega preskusnega standarda je določiti električne, mehanske in toplotne lastnosti koncentratorskih fotonapetostnih modulov in sestavov ter prikazati (kot je mogoče v razumnih stroškovnih in časovnih omejitvah), da lahko koncentratorski fotonapetostni moduli in sestavi prenesejo učinke dolgotrajne izpostavljenosti v okoljih, opisanih v okviru področja uporabe. Dejanska življenjska doba tako ocenjenih koncentratorskih fotonapetostnih modulov in sestavov je odvisna od njihove zasnove, izdelave, okolja uporabe in pogojev delovanja.
Ta standard se uporablja skupaj z navodili za ponovno preskušanje, opisanimi v dodatku B.
