Photovoltaic (PV) modules - Salt mist corrosion testing

IEC 61701:2020 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 third edition cancels and replaces the second edition issued in 2011. 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 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.

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

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.

For the purposes of this document, the terms and definitions given in IEC TS 61836 apply.

ISO and IEC maintain terminological databases for use in standardization at the following

addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
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.

If a full-size sample is too large to fit into the environmental chambers required for the salt

mist test then a smaller representative sample may be specially designed and manufactured

for this test. The representative sample should be carefully designed so that it can reveal

similar failure mechanisms as the full-size one, and the fabrication process of the

representative sample should be as identical as possible to the process of the full-size ones.

The fact that the test has been made on representative samples and not on the full-size

samples shall be reported in the test report under item g), Clause 8.

If the PV module is provided with means for earthing then the earthing connection shall be

tested as part of the module.
5 Test summary

After stabilization, tests are performed to characterize the PV module and confirm it is

operational prior to the salt mist exposure. After the exposure, specimens are cleaned and

allowed to recover. Then this sequence is repeated and the bypass diode functional test is

performed.

All tests included in this document and in Figure 1 and Figure 2 are fully described (including

purpose, apparatus, procedure and requirements) in the referenced clauses of the IEC

Standards listed. Tests included in Figure 1 or Figure 2 shall be performed in the specified

order. In the case of CPV if some test procedures included in this document are not

applicable to a specific design configuration, the manufacturer and the testing agency shall

tailor a comparable test program, based on the principles described in this document. Any

changes and deviations shall be recorded and reported in detail, as required in Clause 8,

item l).
---------------------- Page: 8 ----------------------
IEC 61701:2020 © IEC 2020 – 7 –
6 Test sequence
6.1 General

Refer to Figure 1 for the complete test sequence for non-concentrator PV modules and

Figure 2 for concentrator photovoltaic (CPV) modules.
6.2 Stabilization

All test samples shall undergo electrical stabilization procedures according to MQT 19 in

IEC 61215-2 and any technology specific requirements in the IEC 61215-1-x series.

6.3 Initial and final measurements of non-concentrator modules

For non-concentrator modules, perform the following tests plus any technology specific

modifications described in the 61215-1-x series. The reference MQT (Module Qualification

Test) and MST (Module Safety Test) numbers correspond to the identification in the relevant

document IEC 61215-2 and IEC 61730-2, respectively.
a) MQT 01: Visual inspection
b) MQT 19: Stabilization
c) MQT 02: Maximum power determination
d) MQT 03: Insulation test
e) MST 17: Wet leakage current test
f) MST 13: Continuity test of equipotential bonding
6.4 Initial and final measurements of concentrator photovoltaic (CPV) modules

For concentrator photovoltaic (CPV) modules, perform the following tests according to

IEC 62108:
a) 10.1: Visual inspection
b) 10.2: Electrical performance measurement
c) 10.3: Earth path continuity test
d) 10.4: Electrical insulation test
e) 10.5: Wet insulation test

NOTE The reference before each test corresponds to its corresponding subclause in IEC 62108.

6.5 Salt mist test procedure

6.5.1 A minimum of two test specimens shall be exposed to a cyclic salt mist test

according to one of the methods, except Test Method 2 or Test Method 3, described in

IEC 60068-2-52. Refer to Annex A for guidelines on choosing the appropriate test method.

6.5.2 During testing the face of the PV module normally exposed to solar irradiance shall

be inclined 15° to 30° from vertical inside the salt fog chamber. If using separate chambers for

the different test conditions, care shall be taken to avoid loss of any salt solution deposits

from specimens during transitions. The module may be placed vertically in the humidity

chamber used for the humidity storage portion of the test.
6.6 Cleaning and recovery

After the salt mist test all samples shall be washed to remove the adherent salt using running

tap water (not artificially pressurised) for a maximum time of 5 min per square metre of area

of the sample. Once the washing is finished distilled or demineralized water shall be used to

rinse the samples, followed by complete drying at room temperature. The use of a fan to

accelerate drying is allowed. Caution is recommended when blowing air to accelerate drying

---------------------- Page: 9 ----------------------
– 8 – IEC 61701:2020 © IEC 2020

because excessive air flow can force moisture to penetrate areas it may not normally reach.

The temperature of the water used for washing shall not exceed 35 °C. During cleaning or

drying, wiping specimens with cloths, gauzes or any other material shall be avoided. After

drying, the recovery time shall be minimised and the applicable testing sequence shall be

continued as soon as possible to avoid further damage produced by salt depositions.

6.7 Measurements after salt mist

After the salt mist test, cleaning, and recovery the test samples shall be re-tested according to

6.3 for non-concentrator modules or 6.4 for CPV modules.
6.8 Bypass diode test
6.8.1 Purpose

This test is performed following the salt mist exposure only if the module includes bypass or

blocking diodes. Its purpose is to verify that the bypass or blocking diode(s) of the test

samples remains functional.
6.8.2 Procedure

Perform the test according to MQT 18.1 of IEC 61215-2 except omitting the application of heat

to the specimen. For any technology specific requirements refer to the appropriate 61215-1-x

series document. The modified test steps are as follows:
a) Electrically short any blocking diodes incorporated to the test sample.

Some modules have overlapping bypass diode circuits. In this case it may be necessary to

install a jumper cable to ensure that all of the current is flowing through one bypass diode.

b) Determine the rated STC short-circuit current of the test sample from its label or data

sheet.

c) Connect the DC power source’s positive output to the test sample negative lead, and the

DC power source’s negative output to the test sample positive lead by using wires of the

manufacturer’s minimum recommended wire gauge. Follow the manufacturer’s

recommendations for wire entry into the wiring compartment. With this configuration the

current shall pass through the cells in the reverse direction and through the diode(s) in the

forward direction.

Apply a current equal to of 1,25 times (± 5 %) the STC short-circuit current of the test sample

for a period of 1 h.
6.8.3 Requirements

After the 1 h of current flow check that the bypass diode(s) remains operational according to

MQT 18.2 of IEC 61215-2.
7 Requirements
7.1 General

The two PV samples that undergo the testing sequences included in Figure 1 or Figure 2 shall

exhibit no mechanical deterioration or corrosion of module components which would

significantly impair their function during their intended life.
7.2 Non-concentrator PV modules

All pass fail criteria corresponding to tests MQT 01, MQT 02, MQT 03, MST 17, MST 13 and

MQT 18.2 shall be fulfilled according to what is specified in IEC 61215-1, IEC 61215-2, and

IEC 61730-2 for these specific tests, taking into account any technology specific requirements

or modifications in the IEC 61215-1-x series.
---------------------- Page: 10 ----------------------
IEC 61701:2020 © IEC 2020 – 9 –
7.3 Concentrator photovoltaic (CPV) modules

7.3.1 No significant amount of water should remain inside the test sample after the salt

mist test (the depth of the remaining water should not reach any electrically active parts in

any possible position).

7.3.2 After the salt mist test the relative power degradation shall not exceed 7 % if the I-V

measurement is under outdoor natural sunlight, or 5 % if the I-V measurement is under solar

simulator.

7.3.3 All pass fail criteria corresponding to tests in IEC 62108 10.1, 10.2, 10.3, 10.4 and

10.5 shall be fulfilled according to what is specified for these specific tests.
7.3.4 The bypass diode requirements of 6.8 shall be met.
