Photovoltaic (PV) module performance testing and energy rating - Part 1: Irradiance and temperature performance measurements and power rating

IEC 61853-1:2011 describes requirements for evaluating PV module performance in terms of power (watts) rating over a range of irradiances and temperatures. The object is to define a testing and rating system, which provides the PV module power (watts) at maximum power operation for a set of defined conditions. A second purpose is to provide a full set of characterization parameters for the module under various values of irradiance and temperature.

Prüfung des Leistungsverhaltens von photovoltaischen (PV-)Modulen und Energiebemessung - Teil 1: Leistungsmessung in Bezug auf Bestrahlungsstärke und Temperatur sowie Leistungsbemessung

Essais de performance et caractéristiques assignées d'énergie des modules photovoltaïques (PV) - Partie 1: Mesures de performance en fonction de l'éclairement et de la température, et de caractéristiques de puissance

La CEI 61853-1:2011 définit les exigences relatives à l'évaluation de la performance d'un module PV, en termes de caractéristiques de puissance (watts), sur une plage d'éclairements et de températures. L'objet est de définir un système d'essai et de caractérisation, donnant la puissance (watts) du module PV lorsqu'il fonctionne à puissance maximale et pour un ensemble de conditions définies. Un deuxième objet est de fournir un ensemble complet de paramètres de caractérisation relatif au module, sous diverses valeurs d'éclairement et de température.

Preskušanje zmogljivosti in energijske učinkovitosti fotonapetostnega modula - 1. del: Merjenje vpliva sevanja in temperature na zmogljivost (IEC 61853-1:2011)

Ta del IEC 61853 opisuje zahteve za vrednotenje fotonapetostnega modula glede zmogljivosti (v vatih) pri več različnih sevanjih in temperaturah. IEC 61853-2 opisuje preskusne postopke za merjenje vpliva vpadnega kota, ocenjevanje temperature modula zaradi sevanja, okoljske temperature in hitrosti vetra ter vpliva spektralnega odziva na proizvodnjo energije. IEC 61853-3 opisuje izračune energijskih učinkovitosti fotonapetostnega modula (v vatnih urah). IEC 61853-4 opisuje standardna časovna obdobja in vremenske pogoje, ki se lahko uporabijo za izračun standardiziranih energijskih učinkovitosti.
Cilj tega dela IEC 61853 je opredeliti preskusni in ocenjevalni sistem, ki zagotavlja moč fotonapetostnega modula (v vatih) pri obratovanju z največjo močjo za vrsto opredeljenih pogojev. Drug cilj je zagotoviti celoten niz karakterizacijskih parametrov za modul pri različnih vrednostih sevanja in temperature. Ta niz meritev se zahteva za izvedbo preskušanja energijske učinkovitosti modula, opisane v IEC 61853-3.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publi
