Terrestrial photovoltaic (PV) modules - Design qualification and type approval - Part 1: Test requirements

This document lays down requirements for the design qualification of terrestrial photovoltaic modules suitable for long-term operation in open-air climates. The useful service life of modules so qualified will depend on their design, their environment and the conditions under which they are operated. Test results are not construed as a quantitative prediction of module lifetime.
In climates where 98th percentile operating temperatures exceed 70 °C, users are recommended to consider testing to higher temperature test conditions as described in IEC TS 63126. Users desiring qualification of PV products with lesser lifetime expectations are recommended to consider testing designed for PV in consumer electronics, as described in IEC 63163 (under development). Users wishing to gain confidence that the characteristics tested in IEC 61215 appear consistently in a manufactured product may wish to utilize IEC TS 62941 regarding quality systems in PV manufacturing.
This document is intended to apply to all terrestrial flat plate module materials such as crystalline silicon module types as well as thin-film modules. It does not apply to systems that are not long-term applications, such as flexible modules installed in awnings or tenting.
This document does not apply to modules used with concentrated sunlight although it may be utilized for low concentrator modules (1 to 3 suns). For low concentration modules, all tests are performed using the irradiance, current, voltage and power levels expected at the design concentration.
This document does not address the particularities of PV modules with integrated electronics. It may however be used as a basis for testing such PV modules.
The objective of this test sequence is to determine the electrical characteristics of the module and to show, as far as possible within reasonable constraints of cost and time, that the module is capable of withstanding prolonged exposure outdoors. Accelerated test conditions are empirically based on those necessary to reproduce selected observed field failures and are applied equally across module types. Acceleration factors may vary with product design, and thus not all degradation mechanisms may manifest. Further general information on accelerated test methods including definitions of terms may be found in IEC 62506.
Some long-term degradation mechanisms can only reasonably be detected via component testing, due to long times required to produce the failure and necessity of stress conditions that are expensive to produce over large areas. Component tests that have reached a sufficient level of maturity to set pass/fail criteria with high confidence are incorporated into the IEC 61215 series via addition to Table 1. In contrast, the tests procedures described in this series, in IEC 61215-2, are performed on modules.

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 61215-1 has been prepared by IEC technical committee 82: Solar

photovoltaic energy systems.

This second edition of IEC 61215-1 cancels and replaces the first edition of IEC 61215-1,

published in 2016; it constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) Addition of a test taken from IEC TS 62782.
b) Addition of a test taken from IEC TS 62804-1.

c) Addition of test methods required for flexible modules. This includes the addition of the

bending test (MQT 22).

d) Addition of definitions, references and instructions on how to perform the IEC 61215

design qualification and type approval on bifacial PV modules.
---------------------- Page: 10 ----------------------

IEC 61215-1:2021 © IEC 2021 – 5 –
e) Clarification of the requirements related to power output measurements.
f) Addition of weights to junction box during 200 thermal cycles.
g) Requirement that retesting be performed according to IEC TS 62915.
h) Removal of the nominal module operating test (NMOT), and associated test of
performance at NMOT, from the IEC 61215 series.

Informative Annex A explains the background and reasoning behind some of the more

substantial changes that were made in the IEC 61215 series in progressing from edition 1 to

edition 2.
The text of this International Standard is based on the following documents:
FDIS Report on voting
82/1828A/FDIS 82/1848/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts in the IEC 61215 series, published under the general title Terrestrial

photovoltaic (PV) modules – Design qualification and type approval, can be found on the IEC

website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,

INTRODUCTION

Whereas Part 1 of this standards series describes requirements (both in general and specific

with respect to device technology), the sub-parts of Part 1 define technology variations and

Part 2 defines a set of test procedures necessary for design qualification and type approval.

The test procedures described in Part 2 are valid for all device technologies.

TERRESTRIAL PHOTOVOLTAIC (PV) MODULES –
DESIGN QUALIFICATION AND TYPE APPROVAL –
Part 1: Test requirements
1 Scope

This document lays down requirements for the design qualification of terrestrial photovoltaic

modules suitable for long-term operation in open-air climates. The useful service life of

modules so qualified will depend on their design, their environment and the conditions under

which they are operated. Test results are not construed as a quantitative prediction of module

lifetime.
In climates where 98 percentile operating temperatures exceed 70 °C, users are

recommended to consider testing to higher temperature test conditions as described in

IEC TS 63126. Users desiring qualification of PV products with lesser lifetime expectations

are recommended to consider testing designed for PV in consumer electronics, as described

in IEC TS 63163 (under development). Users wishing to gain confidence that the

characteristics tested in IEC 61215 appear consistently in a manufactured product may wish

to utilize IEC 62941 regarding quality systems in PV manufacturing.

This document is intended to apply to all terrestrial flat plate module materials such as

crystalline silicon module types as well as thin-film modules. It does not apply to systems that

are not long-term applications, such as flexible modules installed in awnings or tenting.

This document does not apply to modules used with concentrated sunlight although it may be

utilized for low concentrator modules (1 to 3 suns). For low concentration modules, all tests

are performed using the irradiance, current, voltage and power levels expected at the design

concentration.

This document does not address the particularities of PV modules with integrated electronics.

It may however be used as a basis for testing such PV modules.

The objective of this test sequence is to determine the electrical characteristics of the module

and to show, as far as possible within reasonable constraints of cost and time, that the

module is capable of withstanding prolonged exposure outdoors. Accelerated test conditions

are empirically based on those necessary to reproduce selected observed field failures and

are applied equally across module types. Acceleration factors may vary with product design,

and thus not all degradation mechanisms may manifest. Further general information on

accelerated test methods including definitions of terms may be found in IEC 62506.

Some long-term degradation mechanisms can only reasonably be detected via component

testing, due to long times required to produce the failure and necessity of stress conditions

that are expensive to produce over large areas. Component tests that have reached a

sufficient level of maturity to set pass/fail criteria with high confidence are incorporated into

the IEC 61215 series via addition to Table 1. In contrast, the tests procedures described in

this series, in IEC 61215-2, are performed on modules.
