EN 61730-1:2007+A11:2014 (E)

– Part 1: Requirements for construction

1 Scope and object

This standard attempts to define the basic requirements for various application classes of PV modules, but it cannot be considered to encompass all national or regional building codes.The specific requirements for marine and vehicle applications are not covered This standard

is not applicable to modules with integrated AC inverters (AC modules)

This standard is designed so that its test sequence can coordinate with those of IEC 61215 orIEC 61646, so that a single set of samples may be used to perform both the safety and performance evaluation of a photovoltaic module design

The object of this document is to provide basic guidance in certifying the fundamentalconstruction of photovoltaic modules presented for safety approval by testing under EN61730-2 These requirements are intended to minimise the misapplication and misuse ofmodules or the breakdown of internal components which would result in fire, electric shock and personal injury The standard defines the basic safety construction requirements and additional tests that are a function of the module end-use applications

Component requirements are intended to provide evidence of performance of that componentappropriate to its application in the module construction and environment

NOTE The additional construction requirements outlined in relevant ISO standards, or the national or local codes which govern the installation and use of these modules in their intended locations, should be considered in addition

to the requirements contained within this document

Relevant safety requirements and necessary tests shall be performed to verify theconformance to the requirements of that application class This clause defines those application classes and construction qualities required for each class

Application classes for PV-modules are defined as follows:

PHOTOVOLTAIC (PV) MODULE SAFETY QUALIFICATION

This part of }EN 61730~ describes the fundamental construction requirements for photovoltaic (PV) modules in order to provide safe electrical and mechanical operation during their expected lifetime 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 }EN 61730~ pertains to the particular requirements of construction }EN 61730-2~ outlines the requirements

3.2 Class A: General access, hazardous voltage, hazardous power applications

Modules rated for use in this application class may be used in systems operating at greater than 120 V DC Modules qualified for safety through this part of EN 61730 and EN 61730-2within this application class are considered to meet the requirements for safety class II

3.3 Class B: Restricted access, hazardous voltage, hazardous power applications

Modules rated for use in this application class are restricted to systems protected from publicaccess by fences, location, etc Modules evaluated within this application class provideprotection by basic insulation, are considered to meet the requirements for safety class 0

3.4 Class C: Limited voltage

Modules rated for use in this application class are restricted to systems operating at less than

120 V DC Modules qualified for safety through this part of EN 61730 and EN 61730-2 withinthis application class are considered to meet the requirements for safety class III

NOTE Safety classes are defined within EN 61140.

4 Construction requirements

4.1 General requirements

4.1.1 All modules shall be able to operate under environmental condition type AB8 according

to IEC 60364-5-51

4.1.2 A module shall be completely assembled when shipped from the factory, or shall be

provided in subassemblies, provided assembly of the product does not involve any action that

is likely to affect compliance with the requirements of the EN 61730 series

4.1.3 An assembly part, such as a terminal compartment cover, need not be affixed to the

module at the factory Incorporation of a module into the final assembly shall not require any alteration of the module from its originally evaluated form, unless specific details describing necessary modification(s) are provided in the installation instructions

4.1.4 If a module must bear a definite relationship to another module for the intended

installation and operation (for example, to allow connectors to mate), it shall be constructed to permit incorporation into the final assembly without the need for alteration

4.1.5 The construction of a module shall be such that ground continuity is not interrupted by

installation

4.1.6 Parts shall be prevented from loosening or turning if such loosening or turning may

result in a risk of fire, electric shock, or injury to persons

4.1.7 Friction between surfaces, such as simple spring pressure, is not acceptable as the

sole means to inhibit the turning or loosening of a part

4.1.8 Any adjustable or movable structural part shall be provided with a locking device to

reduce the likelihood of unintentional movement, if any such movement may result in a risk offire, electric shock, or injury to persons

4.2 Metal parts

4.2.1 Metals used in locations that are exposed to moisture shall not be employed alone or

in combinations that could result in deterioration, such that the product would not comply withthe requirements in this standard

4.2.2 Iron or mild steel serving as a necessary part of the product but not exposed to the

weather shall be plated, painted, or enamelled for protection against corrosion

4.2.3 Simple sheared or cut edges and punched holes are not required to be additionally

protected

5 Polymeric materials

5.2 Polymers serving as an enclosure for live parts

A polymeric material serving as the enclosure of a part involving a risk of fire or electric shock shall comply with the following requirements:

a) 5-V flammability rating (IEC 60695-11-20), either by material test or by testing the end productcomponent;

b) 5-V flammability rating either by material test or testing the end-product design (IEC 60695-11- 20), after the water immersion and exposure test;

d) a minimum resistance to hot wire ignition rating of 30 (IEC 60695-2-20)

Polymers are classified into five operational categories:

– polymers serving as an enclosure for live metal parts (such as a junction box) shall meet requirements as specified in 5.2;

– polymers serving as a support of live metal parts (such as integrated terminals) shall meet the requirements of 5.3;

– polymers serving as the outer surface for the module (such as a frontsheet and backsheet) which do not provide the major mechanical strength for the module shall meet the requirements of 5.4;

– polymers serving as a superstrate or a substrate which provide rigid reinforcement or serve as the carrier for the active cells;

• If the superstrate or substrate polymers are intended for contact with active cells they shall meet requirements as specified in 5.3

• If the superstrate or substrate polymers are intended for use as an outer surface they shall meet requirements as specified in 5.4
