Photovoltaic (PV) module performance testing and energy rating - Part 3: Energy rating of PV modules

IEC 61853-3:2018 describes the calculation of PV module energy rating values. The purpose of this document is to define a methodology to determine the PV module energy output (watt-hours), and the climatic specific energy rating (dimensionless) for a complete year at maximum power operation for the reference climatic profile(s) given in IEC 61853-4. It is applied to determine a specific module output in a standard reference climatic profile for the purposes of comparison of rated modules.

Essais de performance et caractéristiques assignées d'énergie des modules photovoltaïques (PV) - Partie 3: Caractéristiques assignées d’énergie des modules PV

L’IEC 61853-3:2018 décrit le calcul des valeurs des caractéristiques assignées d’énergie des modules PV. Le présent document a pour objet de définir une méthodologie qui permet de déterminer l’énergie produite par les modules PV (watts-heures) et les caractéristiques assignées d’énergie massique pour un profil climatique (adimensionnelles) pour une année complète à la puissance maximale de fonctionnement pour le ou les profils climatiques de référence indiqués dans l’IEC 61853-4. Le présent document est appliqué afin de déterminer une puissance de sortie de module spécifique selon un profil climatique de référence normalisé afin de comparer des modules assignés.

Preskušanje zmogljivosti in energijske učinkovitosti fotonapetostnega (PV) modula - 3. del: Energijska učinkovitost fotonapetostnega (PV) modula

Ta del standarda IEC 61853 opisuje izračun vrednosti energijske učinkovitosti fotonapetostnega (PV) modula. IEC 61853-1 opisuje zahteve za vrednotenje zmogljivosti fotonapetostnega modula pri različnih temperaturah in sevanjih v vrednostih za moč (W). IEC 61853-2 opisuje preskusne postopke za določanje temperature modula pri sevanju, temperaturi okolice in hitrosti vetra, metodo za merjenje učinkov vpadnega kota ter spektralni odziv.
IEC 61853-4 opisuje standardne referenčne podnebne profile (nabore standardnih okoljskih podatkov), ki se uporabljajo za izračun vrednosti energijske učinkovitosti.
Namen tega dokumenta je opredeliti metodologijo za določitev izhodne moči fotonapetostnega modula (Wh) in energijsko učinkovitost pri posameznih podnebnih razmerah (brez dimenzij) za celotno leto pri največji moči delovanja za referenčne podnebne profile, podane v standardu IEC 61853-4. Uporablja se za določitev izhodne moči specifičnega modula v standardnem referenčnem podnebnem profilu za namene primerjave ocenjenih modulov.
Metodologija ne upošteva progresivne degradacije ali prehodnega vedenja, kot so spremembe, ki jih povzroči svetloba, in/ali toplotno žarjenje. Ta dokument se uporablja za enostranske module.

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 61853-3 has been prepared by IEC technical committee 82: Solar

photovoltaic energy systems.
The text of this International Standard is based on the following documents:

INTRODUCTION

This International Standard series establishes IEC requirements for determining PV module

performance in terms of power (watts), specific module energy rating (kWh/kW) and climatic

specific energy rating (dimensionless). It is written to be applicable to all PV technologies

including non-linear devices. The methodology does not take into account either progressive

degradation or transient behaviour such as light induced changes and/or thermal annealing.

This series consists of four parts:

• IEC 61853-1: Photovoltaic (PV) module performance testing and energy rating – Part 1:

Irradiance and temperature performance measurements and power rating, which describes

requirements for evaluating PV module performance in terms of power (watts) rating over

a range of irradiances and temperatures;

• IEC 61853-2: Photovoltaic (PV) module performance testing and energy rating – Part 2:

Spectral responsivity, incidence angle, and module operating temperature measurements,

which describes test procedures for measuring the effect of varying angles of incidence

and sunlight spectra as well as the estimation of module temperature from irradiance,

ambient temperature, and wind speed;

• IEC 61853-3: Photovoltaic (PV) module performance testing and energy rating – Part 3:

Energy rating of PV modules, which describes the calculations for PV module ratings; and

• IEC 61853-4: Photovoltaic (PV) module performance testing and energy rating – Part 4:

Standard reference climatic profiles, which describes the standard time periods and

environmental data set that shall be used for the energy rating calculations.
