TERRESTRIAL PHOTOVOLTAIC (PV) MODULES –
QUALITY SYSTEM FOR PV MODULE MANUFACTURING

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.

TERRESTRIAL PHOTOVOLTAIC (PV) MODULES –
QUALITY SYSTEM FOR PV MODULE MANUFACTURING

1 Scope
This document is applicable to organizations manufacturing photovoltaic (PV) modules
certified to IEC 61215 series and IEC 62108 for design qualification and type approval and
IEC 61730 for safety qualification and type approval. The design qualification and type
approval of PV modules depend on appropriate methods for product and process design, as
well as appropriate control of materials and processes used to manufacture the product. This
document lays out best practices for product design, manufacturing processes, and selection
and control of materials used in the manufacture of PV modules that have met the
requirements of IEC 61215 series, IEC 61730, or IEC 62108. These standards also form the
basis for factory audit criteria of such sites by various certifying and auditory bodies.
The object of this document is to provide a framework for the improved confidence in the
ongoing consistency of performance and reliability of certified PV modules. The requirements
of this document are defined with the assumption that the quality management system of the
organization has already fulfilled the requirements of ISO 9001 or equivalent quality
management system. This document is not intended to replace or remove any requirements of
ISO9001 or equivalent quality management system. By maintaining a manufacturing system in
accordance with this document, PV modules are expected to maintain their performance as
determined from the test sequences in IEC 61215 series, IEC 62108, or IEC 61730.
This document is applicable to all PV modules independent of design and technology, i.e. flat
panel, concentrator photovoltaic (CPV). Quality controls for CPV and nonconventional flat-
plate manufacturing will differ somewhat from those of more conventional designs; this
document has not considered these differences.

4.1 Resources
4.1.1 Succession planning
The organization shall plan for succession for key functions that affect customer satisfaction,
quality, reliability, safety, and performance.
4.1.2 Provision of resources for product warranty system
In addition to the basic QMS-required resource planning, the organization shall determine and
provide the resources needed to maintain the product warranty system, including provision of
after-sales service and for identifying cause of failure and any appropriate follow-up actions
such as adjustment to quality control plan or warranty recall. For repairable products, the
organization shall determine and include staffing and training of service personnel to do in-
field service and adequately plan for maintaining spare part depots and service centres to
ensure the necessary quality of service for customers.

IEC 62941:2019 © IEC 2019 – 11 –
4.2 Monitoring and measuring resources
4.2.1 Control of monitoring and measuring equipment
Monitoring and measurement equipment referenced in the control plan shall be characterized
by measurement system analysis to understand gauge capabilities (repeatability and
reproducibility).
Software shall be considered an integral part of monitoring and measuring equipment and
shall be appropriately controlled and validated. For changes that affect configuration,
including software, the organization shall revalidate monitoring and measurement equipment.
For monitoring and measurement equipment determined to be out of tolerance at the time of
calibration, corrective actions shall be taken to determine impact to the product and
documented per 4.1.
4.2.2 Control of performance rating (IV) measurement equipment
For the equipment used to measure the power performance of the module, the organization
shall maintain a control program compliant to IEC 60891 and IEC 60904 series of standards.
Records of compliance shall be maintained.
Solar simulators shall be initially qualified according to IEC 60904-9 and shall include
characterization of spectrum quality, uniformity of irradiance, and temporal instability of
irradiance. Solar simulator manufacturer’s data may be used to initially validate that the solar
simulator meets the requirements of the organization.
Solar simulators and the methodology used for performance rating shall have an initial
estimate of the uncertainty according to ISO/IEC Guide 98-3. The uncertainty analysis shall
be re-evaluated at least annually. When any critical change is found in measurement
uncertainty, root cause analysis shall be made prior to taking a corrective action. This
information shall be recorded and maintained.
Solar simulators with a BBB rating or better are suggested for performance rating of modules,
but the simulator requirement may vary with the solar cell technology, the geometry of the
module, the match between the reference module and the test modules, and the power
measurement uncertainty if it is indicated on the product literature.
The organization shall retain all calibration documents including the reference device
calibration certificate, or a report that can be traceable to international or national
measurement standards. This information shall be traceable for each module manufactured
and made available to customers upon request.
4.3 Control of documented information
Records related to design, qualification, engineering changes, monitoring, and measurement
of manufacturing processes and products, final testing, and customer details that are
necessary to secure the warranty condition and that are defined by the organization, shall be
retained for at least the warranty period.
5 Operation
5.1 Operational planning and control
In planning product realization, the organization shall also determine the following, as
appropriate:
a) Product certification requirements.

– 12 – IEC 62941:2019 © IEC 2019
b) Design lifetime aligned with the stated warranty under specific conditions and a
documented method to ensure compliance to stated warranty by a combination of product
reliability and after-sales services.
c) Recycling requirements at the end of the modules’ lifetime.
d) Quality assurance and control measures to be applied to production to meet requirements
of the applicable PV standards.
e) ESD safe environmental area.
The organization shall identify the ESD sensitive materials and components and shall
determine an ESD safe environmental area and maintain an ESD safe environment at the
raw material storage, processing, assembly areas, and all through packaging and shipping.
ESD requirements should consider ANSI/ESD S20.20, or equivalent standards.
If ESD protection is sufficient, and it can be determined that the electrostatic potential of
the work areas is low, it would not be necessary to create a designated ‘ESD safe
environmental area’.
f) Packaging, storage and transportation requirements.
Customer requirements and references to related technical specifications, as applicable,
shall be included in the planning of product realization as a component of the quality plan.
NOTE Since the geographies where the modules will be installed may not be identified when they are shipped,
the organization is asked to pay best attention to the generic recycling requirements at the end of the modules’
lifetime.
5.2 Requirements for products and services
5.2.1 Customer communication
The organization shall also determine and implement effective arrangements for
communicating with customers in relation to the following:
a) Safety, workmanship warranty, output power warranty, and installation guidelines
including electrical and mechanical installation instruction.
b) Application notes detailing specific attention and care needed to secure module design
lifetime in the installed configuration.
c) The definition of a warrantable defect or safety critical defect and the rules or process to
manage stated defects, and
d) Product recall notices.
5.2.2 Determining the requirements for products and services
The organization shall determine product warranty workmanship and power degradation and
its relationship to design lifetime under specified and intended use conditions.
The organization shall incorporate requirements arising from applicable previous failure
information, customer complaints, competitive analysis, supplier feedback, and other relevant
inputs. The organization shall maintain traceability to these requirements.
The organization shall establish a method for specifying the nameplate power of a module
with an allowed tolerance at standard test conditions per IEC 61215 series, or IEC 62108 (see
4.2.1 and 4.2.2 for proper control of solar simulators).
5.2.3 Review of the requirements for products and services
The organization shall ensure that all modified products, not covered by the retest guidelines
as defined in IEC TS 62915, are qualified to all related type designs and that the modified
products are evaluated for impact on the safety, performance and warranty.

IEC 62941:2019 © IEC 2019 – 13 –
5.2.4 Organization manufacturing feasibility
The organization shall investigate, conduct risk analysis, confirm and document the
manufacturing feasibility at the necessary scale of the proposed products in the contract
