Varnostna ocena fotonapetostnega (PV) modula - 1. del: Konstrukcijske zahteve
Ta del standarda IEC 61730 določa in opisuje temeljne konstrukcijske zahteve za fotonapetostne (PV) module, da se zagotovi njihovo varno električno in mehansko delovanje. Podane so specifične teme na področju ocene preprečevanja električnega udara, požarne ogroženosti in osebnih poškodb zaradi mehanskih in okoljskih obremenitev. Ta del standarda IEC 61730 se nanaša na posebne gradbene zahteve. Standard IEC 61730-2 določa zahteve za preskušanje.
Ta skupina mednarodnih standardov določa zahteve IEC glede prizemnih fotonapetostnih modulov, primernih za dolgotrajno uporabo v okoljih na prostem. Ta standard je namenjen za uporabo za vse materiale ploščatih prizemnih modulov, kot so vrste modulov iz kristalnega silicija in tankoplastni moduli.
Fotonapetostni moduli, ki jih zajema ta standard, so omejeni na maksimalno napetost v enosmernem sistemu 1500 V.
Ta mednarodni standard določa osnovne zahteve za različne načine uporabe fotonapetostnih modulov, vendar ne zajema vseh nacionalnih in regionalnih predpisov. Specifične zahteve, npr. za uporabo pri gradnji, na morju in v vozilih, niso zajete.
Ta mednarodni standard se ne ukvarja s posebnimi zahtevami za proizvode, v katerih je fotonapetostni modul združen z opremo za pretvorbo energije, elektroniko za nadzor ali kontrolo, kot so vgrajeni inverterji, pretvorniki ali funkcije za onemogočanje izhoda.
Čeprav se lahko deli tega standarda uporabljajo za ploščate fotonapetostne module z notranje ustvarjeno nizko koncentracijo, ki je manjša od 3-kratne, ta standard ni bil oblikovan posebej za te primere.
Ta mednarodni standard je oblikovan tako, da je usklajen s preskusnimi zaporedji iz skupine standardov IEC 61215, zato se lahko za vrednotenje varnosti in učinkovitosti projektiranja fotonapetostnih modulov uporabi ena sama skupina vzorcev.
Namen tega mednarodnega standarda je določanje zahtev za izdelavo fotonapetostnih modulov v zvezi z varnostjo. Te zahteve so namenjene za zmanjšanje nepravilnega delovanja in nepravilne uporabe fotonapetostnih modulov ali odpovedi njihovih sestavnih delov, kar bi lahko povzročilo požar, električni udar in telesne poškodbe.
Poleg zahtev, ki jih vključuje ta standard, je treba upoštevati dodatne konstrukcijske zahteve, podane v relevantnih standardih ISO, ali nacionalne oziroma lokalne predpise, ki urejajo namestitev in uporabo teh fotonapetostnih modulov na njihovih predvidenih lokacijah.

PHOTOVOLTAIC (PV) MODULE SAFETY QUALIFICATION –
Part 1: Requirements for construction
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 61730-1 has been prepared by IEC technical committee 82: Solar
photovoltaic energy systems.
This second edition cancels and replaces the first edition of IEC 61730-1, issued in 2004, and
its amendments 1 (2011) and 2 (2013); it constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Adaption of horizontal standards and inclusion of IEC 60664 and IEC 61140.
b) Implementation of insulation coordination, overvoltage category, classes, pollution degree
(PD), and material groups (MG).
c) Implementation of component qualification.
d) IEC Guide 108 Guidelines for ensuring the coherency of IEC publications – Application of
horizontal standards.
– 6 – IEC 61730-1:2016 © IEC 2016
e) Definition of creepage (cr), clearance (cl) and distance through insulation.
The text of this standard is based on the following documents:
FDIS Report on voting
82/1128/FDIS 82/1146/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 61730 series, published under the general title Photovoltaic (PV)
module safety qualification, can be found on the IEC website.

PHOTOVOLTAIC (PV) MODULE SAFETY QUALIFICATION –
Part 1: Requirements for construction
1 Scope
This part of IEC 61730 specifies and describes the fundamental construction requirements for
photovoltaic (PV) modules in order to provide safe electrical and mechanical operation.
Specific topics are provided to assess the prevention of electrical shock, fire hazards, and
personal injury due to mechanical and environmental stresses. This part of IEC 61730
pertains to the particular requirements of construction. IEC 61730-2 defines the requirements
for testing.
This International Standard series lays down IEC requirements of terrestrial photovoltaic
modules suitable for long-term operation in open-air climates. This standard is intended to
apply to all terrestrial flat plate module materials such as crystalline silicon module types as
well as thin-film modules.
PV modules covered by this standard are limited to a maximum DC system voltage of
1 500 V.
This International Standard defines the basic requirements for various applications of PV
modules, but it cannot be considered to encompass all national or regional codes. Specific
requirements, e.g. for building, marine and vehicle applications, are not covered.
This International Standard does not address specific requirements for products that combine
a PV module with power conversion equipment, monitoring or control electronics, such as
integrated inverters, converters or output disabling functions.
While parts of this standard may be applicable to flat plate PV modules with internally
generated low level concentration below 3 times, it was not written specifically to address
these concerns.
This International Standard is designed to coordinate with the test sequences in the
IEC 61215 series, so that a single set of samples may be used to perform both the safety and
qualification of a photovoltaic module design.
The object of this International Standard is to define the requirements for the construction of
photovoltaic modules with respect to safety. These requirements are intended to minimize the
misapplication and misuse of PV modules or the failure of their components which could
result in fire, electric shock and personal injury.
Additional construction requirements outlined in relevant ISO standards, or the national or
local codes which govern the installation and use of these PV modules in their intended
locations, should be considered in addition to the requirements contained within this standard.

Relationship between this European standard and the safety
objectives of Directive 2014/35/EU [2014 OJ L96] aimed to be
covered
This European Standard has been prepared under a Commission’s standardization request relating to
harmonized standards in the field of the Low Voltage Directive, M/511, to provide one voluntary means
of conforming to safety objectives of Directive 2014/35/EU of the European Parliament and of the
Council of 26 February 2014 on the harmonization of the laws of the Member States relating to the
making available on the market of electrical equipment designed for use within certain voltage limits
[2014 OJ L96].
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZZ.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding safety objectives of
that Directive, and associated EFTA regulations.

Part 1: Requirements for construction
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 61730-1 has been prepared by IEC technical committee 82: Solar
photovoltaic energy systems.
This second edition cancels and replaces the first edition of IEC 61730-1, issued in 2004, and
its amendments 1 (2011) and 2 (2013); it constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous

PHOTOVOLTAIC (PV) MODULE SAFETY QUALIFICATION –
Part 1: Requirements for construction
1 Scope
This part of IEC 61730 specifies and describes the fundamental construction requirements for
photovoltaic (PV) modules in order to provide safe electrical and mechanical operation.
Specific topics are provided to assess the prevention of electrical shock, fire hazards, and
personal injury due to mechanical and environmental stresses. This part of IEC 61730
pertains to the particular requirements of construction. IEC 61730-2 defines the requirements
for testing.
This International Standard series lays down IEC requirements of terrestrial photovoltaic
modules suitable for long-term operation in open-air climates. This standard is intended to
apply to all terrestrial flat plate module materials such as crystalline silicon module types as
well as thin-film modules.
PV modules covered by this standard are limited to a maximum DC system voltage of
1 500 V.
This International Standard defines the basic requirements for various applications of PV
modules, but it cannot be considered to encompass all national or regional codes. Specific
requirements, e.g. for building, marine and vehicle applications, are not covered.
This International Standard does not address specific requirements for products that combine
a PV module with power conversion equipment, monitoring or control electronics, such as
integrated inverters, converters or output disabling functions.
While parts of this standard may be applicable to flat plate PV modules with internally
generated low level concentration below 3 times, it was not written specifically to address
these concerns.
This International Standard is designed to coordinate with the test sequences in the
IEC 61215 series, so that a single set of samples may be used to perform both the safety and
qualification of a photovoltaic module design.
The object of this International Standard is to define the requirements for the construction of
photovoltaic modules with respect to safety. These requirements are intended to minimize the
misapplication and misuse of PV modules or the failure of their components which could
result in fire, electric shock and personal injury.
Additional construction requirements outlined in relevant ISO standards, or the national or
local codes which govern the installation and use of these PV modules in their intended
locations, should be considered in addition to the requirements contained within this standard.
