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.
