Overview

IEC 63092-2:2020 - "Photovoltaics in buildings – Part 2: Requirements for building‑integrated photovoltaic systems" - defines system-level requirements for building-integrated photovoltaic (BIPV) installations where photovoltaic modules are used as building products. Unlike IEC 63092-1 (which covers BIPV module requirements), this Part 2 standard focuses on the properties of the BIPV system, including how modules are mounted, the mounting structure and the electrotechnical and basic building requirements relevant to safe, durable integration.

Key topics and technical requirements

• Scope and applicability
  • Applies to BIPV systems integrated into buildings (not concentrating PV).
  • Covers properties relevant to basic building functions and electrotechnical safety.
• Electrotechnical requirements (Clause 4.1)
  • System-level electrical safety, protection, earthing and wiring practices referenced to IEC 60364 series and related PV electrical guidance.
• Building-related requirements (Clause 4.2)
  • General performance expectations for weather resistance, mechanical integration and fire/safety interfaces.
  • Specific requirements for systems using modules with at least one glass pane and for systems using modules without glass panes (e.g., polymer or metal-sheet-based coverings).
• Labelling, documentation, commissioning and inspection
  • Requirements for system labelling, preparation of technical documentation, commissioning tests and acceptance inspection (Clauses 5–6).
  • Reporting requirements to demonstrate conformity and support maintenance (Clause 7).
• Test methods and informative annexes
  • Annex A: an informative test method for resistance to wind‑driven rain of discontinuously laid BIPV roof coverings.
• Normative references
  • Integrates numerous IEC and ISO standards (e.g., IEC 60364, IEC 61215, IEC 61730, IEC 62446, ISO structural and thermal standards) to address electrical, mechanical and thermal considerations.

Practical applications and who uses this standard

IEC 63092-2 is intended for:

• Manufacturers of BIPV systems and mounting solutions
• Architects, planners and system designers integrating PV as building materials (facades, roofs, curtain walls)
• Installers and contractors executing BIPV mounting and electrical connections
• Testing and certification bodies verifying system compliance
• Building authorities and specifiers assessing building-product performance and safety

Use cases include ensuring safe electrical integration, demonstrating weather and mechanical performance of mounted BIPV assemblies, preparing commissioning documentation, and complying with building-code requirements when PV modules substitute conventional building elements.

Related standards

• IEC 63092-1 (BIPV modules)
• IEC 60364 series (low-voltage installations)
• IEC 61215 / 61730 (PV module qualification & safety)

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.

PHOTOVOLTAICS IN BUILDINGS –
Part 2: Requirements for building-integrated photovoltaic systems

1 Scope
IEC 63092-1 specifies BIPV (building-integrated photovoltaic) module requirements while this
document specifies BIPV system requirements. Both parts specify building requirements and
the applicable electrotechnical requirements (both in general and specific with respect to
module assembly and application category).
This document applies to photovoltaic systems that are integrated into buildings with the
photovoltaic modules used as building products. It focuses on the properties of these
photovoltaic systems relevant to basic building requirements and the applicable electrotechnical
requirements. This document references international standards, technical reports and
guidelines. For some applications, national standards (or regulations) for building products may
also apply in individual countries, which are not explicitly referenced here and for which
harmonized International Standards are not yet available.
This document is addressed to manufacturers, planners, system designers, installers, testing
institutes and building authorities.
This document does not apply to concentrating photovoltaic systems or photovoltaic systems
using concentrating photovoltaic modules.
This document addresses requirements on the BIPV systems in the specific ways they are
intended to be mounted and the mounting structure, but not the BIPV module itself, which is
within the scope of IEC 63092-1.

3.1
building-integrated photovoltaic system
BIPV system
photovoltaic system in which the PV modules satisfy the definition of IEC 63092-1 for
BIPV modules. It includes the “PV array” as defined by IEC 62548 and the mechanical mounting
systems needed to integrate the BIPV modules into the building
Note 1 to entry: Inverters are not addressed here, as they are adequately covered by International Standards
applying to inverters in PV systems. Building integration of a PV system does not change the requirements on the
inverters.
3.2
optically representative area of the system
selected surface area of the system that includes all the components of the system which have
a significant effect on its optical properties and g value. The ratio of electrically active area (i.e.
area covered by PV cells and interconnectors) to electrically inactive area within the optically
representative area should not differ by more than 5 % from the ratio of the total electrically
active area to the total electrically inactive area for the complete system (see Figure 1)
Note 1 to entry: The figure of 5 % was determined to result in an error of 3 % or less in the g value for BIPV modules
consisting of crystalline silicon PV cells spaced in a light-transmitting medium.
Note 2 to entry: The g value refers to the solar heat gain coefficient (SHGC) as defined in ISO 19467.
Note 3 to entry: If the solar cells themselves consist of opaque and transparent areas, or there are inhomogeneous
layers such as ceramic frits or coloured interlayers in front of the solar cell layer, special care shall be taken in the
selection of the "optically representative area" to ensure that it represents the proportions of all optically different
areas of the BIPV system to within the specified tolerance.

risk of accidents or damage in service or in operation such as slipping, falling, collision, burns,
electrocution, injury from explosion and burglary. In particular, they shall be designed and built
taking accessibility and use by people with disabilities into account. Their needs have also been
translated into different requirements, both from the perspective of electrical safety and of
construction/mechanical safety.
The impact testing according to ISO 29584 shall be carried out on representative samples of
the BIPV end-product. Representative samples shall be operational PV modules containing all
the relevant parts, but not the full-size dimensions used in the building. The area of the
representative samples shall be at least 1 m x 1 m, with the same thickness and support
structure around the edges as the BIPV end-product.
NOTE National regulations may define restrictions or additional requirements (e.g., calculation of glass thickness
as specified by applicable building code).
4.2.2.5.2 Pendulum test for systems
BIPV systems shall meet the impact requirements of IEC 61730-2 MST 32, and ISO 29584
together with those of the local national building code (or similar) for the building function they
provide. It should be noted that additional testing for impact from both sides of the system may
be required.
4.2.2.5.3 Structural sealant glazing systems
For BIPV systems consisting of BIPV modules or PV insulating glass units to be bonded
adhesively to the substructure, and which are sold separately from the substructure and
installed under the responsibility of the designer and assembler, the following standards shall
apply:
– ISO 28278-1
– ISO 28278-2
4.2.2.6 Protection against noise
No requirements are specified.
Until an international standard is published, national or local codes or standards may apply.

4.2.2.7 Energy economy and heat retention
4.2.2.7.1 General
Buildings and their heating, cooling, lighting and ventilation installations should be designed
and built in such a way that the amount of energy they require in use is low, when account is
taken of the occupants and the climatic conditions at the building location. Buildings should also
be energy-efficient throughout their entire life cycle, using as little energy as possible during
their construction and dismantling.

4.2.2.7.2 Light transmittance, solar direct transmittance and total solar energy
transmittance
4.2.2.7.2.1 General
The purpose of these methods is to determine light and energy transmittance of solar radiation
for glazing systems in buildings. These characteristic data can serve as a basis for lighting,
heating and ventilation calculations of rooms and can permit comparison between different
glazing systems. One or more of the following methods shall be used:
In addition to the procedures defined in the following clauses to determine the total solar energy
transmittance of glazing systems, calculations or measurements are permitted that take account
of the fact that some of the absorbed solar energy will be converted to electricity rather than
heat, thus changing the value of the secondary heat transfer factor towards the inside.
NOTE 1 Total solar energy transmittance (TSET), g value and solar heat gain coefficient (SHGC) are physically
equivalent quantities.
4.2.2.7.2.2 Calculation method based on spectral measurements
One or more of the following standards shall apply:
– ISO 9050
– ISO 15099
The transmittance of optically differing areas of the system shall be determined separately,
each according to ISO 9050. The transmittance for the whole system is then calculated as an
area-weighted average of the individual transmittance values.
Alternatively, the transmittance shall be measured with a large beam cross-section that covers
a optically representative area of the system.
Depending on the application, compliance to ISO 52022-1 and ISO 52022-3 may also be
required for application categories B and D when a solar protection device, such as a louver,
venetian or roller blind, is incorporated parallel to the glazing. The position of the solar
protection device can be interior, exterior or between individual panes in a multi-pane glazing
system.
One or more of the following standards shall apply for solar protection systems combined with
glazing (application category E):
– ISO 52022-1
– ISO 52022-3
4.2.2.7.2.3 Measurement method for solar heat gain coefficient using solar
simulator
The following standard shall apply for solar-protection devices mounted parallel to doors or
windows, under application category D:
– ISO 19467
NOTE The measurement procedures under maximum power point (MPP) are not yet established.
For other application categories, national or local codes or standards may apply.

4.2.2.7.3 Thermal transmittance
The purpose of this method is to determine the thermal transmittance (U value) of a glazing
system with flat and parallel surfaces. The following standard shall apply:
– ISO 6946
The following standard shall also apply for curtain wall systems (application categories C and
D, if relevant):
– ISO 12631
4.2.2.8 Sustainable use of natural resources
Until an international standard is published, national or local codes or standards may apply.
