Description (English):

IEC 61730-2:2023 lists the tests a PV module is required to fulfil for safety qualification. This document applies for safety qualification only in conjunction with IEC 61730-1. The objective of this document is to provide the testing sequence intended to verify the safety of PV modules whose construction has been assessed by IEC 61730-1. The test sequence and pass criteria are designed to detect the potential breakdown of internal and external components of PV modules that would result in fire, electric shock, and/or personal injury. This document defines the basic safety test requirements and additional tests that are a function of the PV module end-use applications. The additional testing requirements outlined in relevant ISO documents, or the national or local codes which govern the installation and use of these PV modules in their intended locations, are considered in addition to the requirements contained within this document. The content of the corrigendum 1 (2024-10) has been included in this copy.

Abstract

Overview

IEC 61730-2:2023 - Photovoltaic (PV) module safety qualification Part 2: Requirements for testing - specifies the test sequence and criteria used to verify the safety of PV modules whose construction has been assessed under IEC 61730-1. Edition 3.0 (2023-09) with Corrigendum 1 (2024-10) defines the basic safety tests and additional tests tied to intended end-use, aimed at detecting failures that could lead to fire, electric shock, or personal injury. The standard is for safety qualification only and is used together with IEC 61730-1; it also recognizes additional requirements from relevant ISO documents and national/local codes.

Key technical topics and requirements

The document organizes tests into clear categories and specifies test procedures, sampling and pass criteria:

Test categories: environmental stress tests, general inspection, electrical shock hazard, fire hazard, mechanical stress.
Test sequence and pass criteria: procedures to detect internal/external component breakdown that may cause hazardous conditions.
Representative test procedures (identified by MST numbers) include:
- Visual inspection (MST 01) and performance checks at STC (MST 02/MST 03)
- Insulation and leakage tests (MST 04, MST 16, MST 17)
- Fire and ignitability tests (MST 23, MST 24)
- Mechanical tests: static mechanical load, module breakage, peel and lap shear (MST 21/32/34/35/36)
- Thermal and environmental durability: thermal cycling, damp heat, humidity-freeze, UV, hot-spot endurance (MST 51–54, 22, 52–53)
- Termination and connector robustness, bypass diode and reverse current overload tests (MST 25–26, 33, 42)
Documentation: sampling plans, detailed test reports and final pass/fail criteria are defined to support certification.

Practical applications and who uses this standard

IEC 61730-2 is essential for anyone involved in PV safety assessment and certification:

PV module manufacturers - design validation and safety qualification prior to market release
Test laboratories and certification bodies - standardized test procedures and reporting for safety certification
System designers, EPC contractors and installers - understanding module safety limits for system integration and risk mitigation
Regulators and code authorities - reference for compliance with electrical safety and fire-safety requirements
Insurance and risk assessors - evidence of tested safety performance for underwriting

Related standards

IEC 61730-1 (construction and qualitative requirements) - mandatory companion to Part 2
Relevant ISO documents and national/local electrical and fire codes - may add application-specific testing or installation requirements

Keywords: IEC 61730-2:2023, PV module safety, photovoltaic module testing, safety qualification, test sequence, fire hazard, electrical shock, environmental stress tests, pass criteria.
