(Main)Crystalline silicon photovoltaic (PV) array - On-site measurement of I-V characteristics
Crystalline silicon photovoltaic (PV) array - On-site measurement of I-V characteristics
IEC 61829:2015 specifies procedures for on-site measurement of flat-plate photovoltaic (PV) array characteristics, the accompanying meteorological conditions, and use of these for translating to standard test conditions (STC) or other selected conditions. This new edition includes the following significant technical changes with respect to the previous edition:
- it addresses many outdated procedures;
- it accommodates commonly used commercial I-V curve tracers;
- it provides a more practical approach for addressing field uncertainties;
- it removes and replaces procedures with references to other updated and pertinent standards, including the IEC 60904 series, andIEC 60891.
Photovoltaische (PV) Modulgruppen - Messen der Strom-Spannungs-Kennlinien am Einsatzort
Champ de modules photovoltaïques (PV) au silicium cristallin - Mesure sur site des caractéristiques I-V
L'IEC 61829:2015 spécifie les procédures relatives au mesurage sur site des caractéristiques d'un champ de modules photovoltaïques (PV) à plaque plane avec les conditions climatiques associées et l'utilisation de celles-ci pour leur transposition dans des conditions normales d'essai (STC - standard test conditions) ou dans d'autres conditions sélectionnées. Cette nouvelle édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- elle traite de plusieurs procédures obsolètes;
- elle tient compte des traceurs de courbe I-V commerciaux couramment utilisés;
- elle fournit une approche plus pratique pour gérer les incertitudes associées aux champs;
- elle supprime et remplace certaines procédures par d'autres normes pertinentes et mises à jour, parmi lesquelles la série IEC 60904 et l'IEC 60891.
Fotonapetostno polje iz kristalnega silicija – Merjenje karakteristike I-U na mestu vgradnje
Ta mednarodni standard določa postopke za merjenje karakteristik fotonapetostnega polja (PV) na ploščati ploščici na mestu vgradnje ter spremljevalne vremenske pogoje in njihovo uporabo za pretvarjanje v standardne pogoje preskušanja (STC) ali druge izbrane pogoje. Meritve karakteristik tok-napetost (I-V) fotonapetostnega polja pod dejanskimi pogoji na mestu vgradnje in njihova pretvorba v referenčne pogoje preskušanja (RTC) lahko omogoči naslednje:
• podatke o nazivni moči ali preskusni zmogljivosti;
• preverjanje zmogljivosti moči montiranega polja glede na specifikacijo zasnove;
• zaznavanje morebitnih razlik med karakteristikami modulov na mestu vgradnje in laboratorijskimi ali tovarniškimi meritvami;
• zaznavanje morebitnega slabšega delovanja modulov in polj glede na začetne podatke na mestu vgradnje;
• zaznavanje morebitnih okvar modulov ali polj ali slabega delovanja.
Meritve na mestu vgradnje za določeni modul, ki so pretvorjene v standardne pogoje preskušanja, je mogoče neposredno primerjati z rezultati za zadevni modul, ki so bili predhodno pridobljeni v laboratoriju ali tovarni. Korekcije za razlike v spektralnem ali prostorskem odzivu referenčnih naprav je morda treba oceniti, kot je opredeljeno v standardu IEC 60904.
Na meritve polja na mestu vgradnje vplivajo dioda, kabel in izgube zaradi neujemanja, umazanost in senčenje, slabšanje zaradi staranja ter drugi nenadzorovani učinki. Zato se od meritev ne pričakuje, da bodo enake zmnožku števil modulov in ustreznim podatkom o modulih.
Če se fotonapetostno polje oblikuje s podpolji z različnim naklonom, usmeritvijo, tehnologijo ali električno konfiguracijo, velja za vsako zadevno edinstveno podpolje fotonapetostnega polja postopek, ki ga določa ta mednarodni standard.

PHOTOVOLTAIC (PV) ARRAY –
ON-SITE MEASUREMENT OF CURRENT-VOLTAGE CHARACTERISTICS
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 Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61829 has been prepared by IEC technical committee 82: Solar
photovoltaic energy systems.
This second edition cancels and replaces the first edition published in 1995. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) it addresses many outdated procedures;
b) it accommodates com
