Annotation of standard text IEC 61724-1-ed.2.0 :

IEC 61724-1:2021 outlines terminology, equipment, and methods for performance monitoring and analysis of photovoltaic (PV) systems. It also serves as a basis for other standards which rely upon the data collected. This document defines classes of photovoltaic (PV) performance monitoring systems and serves as guidance for monitoring system choices. This second edition cancels and replaces the first edition, published in 2017. This edition includes the following significant technical changes with respect to the previous edition: - Monitoring of bifacial systems is introduced. - Irradiance sensor requirements are updated. - Soiling measurement is updated based on new technology. - Class C monitoring systems are eliminated. - Various requirements, recommendations and explanatory notes are updated. LIEC 61724-1:2021 presente une terminologie, des equipements et des methodes relatifs a la surveillance des performances et a l’analyse des systemes photovoltaiques (PV). Elle sert egalement de base a d’autres normes qui s’appuient sur les donnees collectees. Cette deuxieme edition annule et remplace la premiere edition parue en 2017. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - Presentation de la surveillance des modules PV bifaciaux. - Mise a jour des exigences relatives aux capteurs d’eclairement energetique. - Mise a jour du mesurage de l’encrassement pour tenir compte des nouvelles technologies. - Suppression des systemes de surveillance de classe C. - Mise a jour de differentes exigences, recommandations et notes explicatives.
