Terrestrial photovoltaic (PV) modules - Design qualification and type approval - Part 1-4: Special requirements for testing of thin-film Cu(In,GA)(S,Se)2 based photovoltaic (PV) modules
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 62941 regarding quality systems in PV manufacturing.
This document is intended to apply to all thin-film Cu(In,Ga)(S,Se)2 based terrestrial flat plate
modules. As such it addresses special requirements for testing of this technology
supplementing IEC 61215-1:2021 and IEC 61215-2:2021 requirements for testing.
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.
The object 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 IEC 61215-1. In contrast, the tests procedures
described in this series, in IEC 61215-2, are performed on modules.
This document defines PV technology dependent modifications to the testing procedures and
requirements per IEC 61215-1:2021 and IEC 61215-2:2021.

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 61215-1-4 has been prepared by IEC technical committee 82:
Solar photovoltaic energy systems.
This second edition cancels and replaces the first edition of IEC 61215-1-4, issued in 2016,
and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) A cyclic (dynamic) mechanical load test (MQT 20) added.
b) A test for detection of potential-induced degradation (MQT 21) added.
c) A bending test (MQT 22) for flexible modules added.

The text of this standard is based on the following documents:
FDIS Report on voting
82/1827/FDIS 82/1852/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.
This standard is to be read in conjunction with IEC 61215-1:2021 and IEC 61215-2:2021.
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,
• replaced by a revised edition, or
• amended.
