Full title and description
Photovoltaic (PV) module safety qualification — Part 1: Requirements for construction (IEC 61730-1:2023). This part defines the fundamental construction requirements for terrestrial flat-plate PV modules to ensure safe electrical, mechanical and fire performance over the expected lifetime of the module. It complements IEC 61730-2, which contains the associated testing requirements.
Abstract
IEC 61730-1:2023 specifies construction-level requirements for PV modules to mitigate electrical shock, fire and mechanical/personal-injury hazards. The document applies to crystalline and thin-film flat-plate modules intended for outdoor terrestrial operation (with guidance for higher-operating-temperature applications provided in related technical specifications). It establishes material, design and marking expectations that feed into the module safety qualification process used by manufacturers, test laboratories and certification bodies.

Scope
Sets out construction requirements for terrestrial flat-plate photovoltaic modules to achieve safe electrical and mechanical performance in normal outdoor service. The standard addresses design and material choices that prevent electrical shock, reduce fire risk and limit hazards from mechanical failures and environmental stresses. It is intended for modules with 98th-percentile operating temperatures up to 70 °C; guidance for higher-temperature applications is referenced in relevant IEC technical specifications. IEC 61730-1 is to be used together with IEC 61730-2 (testing) and other normative documents where indicated.
Key topics and requirements
- Fundamental construction requirements for safe operation (insulation, creepage/clearance concepts and protective measures).
- Materials and component requirements (encapsulants, backsheets, frames, junction boxes, connectors, bypass diodes) and their suitability for outdoor use.
- Electrical safety provisions: grounding/earthing, isolation, marking and protection against accessible live parts.
- Fire-safety considerations and classifications related to module construction and materials.
- Mechanical design requirements addressing static and dynamic loads (wind, snow, handling) and resistance to hail and impact.
- Environmental durability guidance for UV, moisture, temperature cycling and corrosion resistance as they affect safe construction.
- Marking, documentation and information required for safe installation, use and maintenance (ratings, warnings, instructions).
- Relationship to testing procedures (tests and sequence defined in IEC 61730-2 and related technical specifications for special conditions).
Typical use and users
Primary users include PV module manufacturers (for design and compliance), test and certification laboratories, regulatory agencies and conformity-assessment bodies, system integrators and installers (for understanding required markings and safe installation practices), and R&D teams assessing material or design changes that affect module safety.
