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

PHOTOVOLTAIC (PV) MODULES –
SALT MIST CORROSION TESTING
1 Scope
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, MgCl , 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.

4 Samples
Three identical samples of the model of PV module or assembly of interest shall be subjected
to any of the testing sequences included in Figure 1 or Figure 2 for non-concentrator PV or
concentrator photovoltaic (CPV) respectively. As the figures indicate one of these samples
should be used as a control. The control sample should be used as a check every time the
test samples are measured to evaluate the effect of the salt mist test.
In the case of CPV different situations for choosing the sample may occur. For non-field-
adjustable focus-point CPV systems or modules, 3 modules are required to complete the
testing sequence included in Figure 2. For field-adjustable focus-point CPV systems or
assemblies, 3 receivers (including secondary optics sections, if applicable) and 3 primary
optics sections are required to complete the testing sequence included in Figure 2. A
complete description of the different types and components of CPV modules and assemblies
can be found in IEC 62108.

The EN IEC 61701:2020 standard, which focuses on photovoltaic (PV) modules and their resistance to salt mist corrosion, is a critical document in the renewable energy sector. The scope of the standard is comprehensive as it establishes test sequences necessary to assess the durability of various PV modules against corrosion induced by salt mist, which is composed of chemicals such as NaCl and MgCl2. This is particularly significant for PV modules deployed in coastal areas or environments with high salinity, where corrosion can affect performance and longevity. One of the primary strengths of EN IEC 61701:2020 lies in its detailed integration with existing standards, specifically IEC 61215-2, IEC 62108, IEC 61730-2, and IEC 60068-2-52. By combining functionalities and methodologies from these well-regarded standards, it provides a robust framework for evaluating the potential faults that may occur in PV modules under wet and saline conditions. The modification of the bypass diode functionality test enhances its relevance, ensuring that it accurately reflects operational realities. Furthermore, the recent updates in this third edition indicate a thorough review and adaptation to contemporary needs. The refined scope accurately encapsulates the applicability of the standard, while the condensation and alignment of test methods with new editions of relevant standards showcase an effort to streamline processes and enhance clarity. The removal of references to specific technologies, such as crystalline silicon and thin film, promotes a more inclusive approach relevant to all PV technologies. In addition to these improvements, the inclusion of a normative annex is a significant advancement, offering guidance on selecting appropriate test methods based on the specific application.
