Photovoltaic (PV) modules - Salt mist corrosion testing

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 61701 has been prepared by IEC technical committee 82: Solar photovoltaic energy systems.

This third edition cancels and replaces the second edition issued in 2011. This edition constitutes a technical revision.

The main technical changes with respect to the previous edition are as follows:

•

The scope has been updated to better reflect the applicability of the Standard.

•

Test methods and requirements have been condensed and aligned with the new editions of IEC 61215–1, IEC 61215–2, and IEC 61730–2. References to crystalline silicon versus thin film technologies have been eliminated. The old Figure 2 on the thin film test sequence has been eliminated.

•

The salt mist test references have been updated to harmonize with changes to IEC 60068‑2‑52.

•

A normative annex A has been added to provide guidance on which of the test methods in IEC 60068‑2‑52 are applicable to different applications. This includes references to new test methods in the latest edition of IEC 60068‑2‑52.

The text of this International Standard is based on the following documents:

FDIS	Report on voting
82/1693/FDIS	82/1725/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.

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.

Photovoltaic (PV) modules - Salt mist corrosion testing

1Scope

Photovoltaic (PV) modules are electrical devices normally intended for continuous outdoor exposure during their lifetime. Highly corrosive wet atmospheres, such as marine environments or locations near the ocean or other large bodies of salt water, could eventually degrade some of the PV module components (corrosion of metallic parts, deterioration of the properties of some non-metallic materials – such as protective coatings and plastics – by assimilation of salts, etc.) causing permanent degradation that could impair their functioning. Temporary corrosive atmospheres are also present in places where salt is used in winter periods to melt ice formations on streets and roads.

This document describes test sequences useful to determine the resistance of different PV modules to corrosion from salt mist containing Cl (NaCl, MgCl2, etc.). All tests included in the sequences are fully described in IEC 61215–2, IEC 62108, IEC 61730–2 and IEC 60068‑2‑52. The bypass diode functionality test in this document is modified from its description in IEC 61215–2. They are combined in this document to provide means to evaluate possible faults caused in PV modules when operating under wet atmospheres having high concentration of dissolved salt (NaCl). Depending on the specific nature of the surrounding atmosphere to which the module is exposed in real operation several testing methods can be applied, as defined in IEC 60068‑2‑52. Guidance for determining the applicability of this document and selecting an appropriate method is provided in Annex A.

This document can be applied to both flat plate PV modules and concentrator PV modules and assemblies.
