IEC 61215-1-1:2016

Overview

IEC 61215-1-1:2016 is an international standard published by the International Electrotechnical Commission (IEC) that focuses on the design qualification and type approval of terrestrial crystalline silicon photovoltaic (PV) modules. This part of the IEC 61215 series specifically addresses the special requirements for testing crystalline silicon PV modules, ensuring their long-term reliable operation in general open-air climate conditions as outlined in IEC 60721-2-1.

The standard aims to verify the electrical and thermal characteristics of crystalline silicon PV modules through a rigorous test sequence. The objective is to demonstrate the module’s ability to withstand prolonged environmental exposure, thus supporting safe deployment of high-performance PV technology under realistic operational scenarios.

IEC 61215-1-1:2016 is applicable exclusively to flat plate terrestrial crystalline silicon PV modules and excludes modules used with high concentration sunlight systems. Modules designed for low concentration (1 to 3 suns) applications may be tested following the standard with appropriate adjustments.

Key Topics

• Design Qualification and Type Approval
  The standard defines requirements and procedures for assessing module durability and performance, enabling manufacturers and stakeholders to certify crystalline silicon PV modules according to global benchmarks.

• Test Procedures and Requirements
  IEC 61215-1-1:2016 incorporates technology-specific modifications to the general testing methods from IEC 61215-1:2016 and IEC 61215-2:2016, ensuring that tests accurately represent conditions experienced by crystalline silicon modules. Important tests include:

  • Visual inspection (MQT 01)
  • Maximum power determination (MQT 02)
  • Insulation tests (MQT 03)
  • Temperature coefficient measurements (MQT 04)
  • Nominal Module Operating Temperature (NMOT) measurement (MQT 05)
  • Performance testing at Standard Test Conditions (STC) and NMOT (MQT 06)
  • Outdoor exposure and durability tests (e.g., hot-spot endurance, UV preconditioning, thermal cycling)

• Pass Criteria and Reporting
  The standard stipulates clear pass criteria, including the maximum allowable reproducibility value of 1.0%, and requires comprehensive reporting documentation. This ensures traceability and transparency in the qualification process.

• Electrical and Thermal Characterization
  Critical to module qualification, these measurements ensure that crystalline silicon PV modules meet performance thresholds under varying thermal loads and irradiance conditions.

Applications

IEC 61215-1-1:2016 is essential for manufacturers, testing laboratories, certification bodies, and project developers who require rigorous validation of crystalline silicon PV modules' performance and durability. It is especially useful for:

• Module Manufacturers
  To design, test, and validate crystalline silicon modules, ensuring compliance with international quality and safety standards, thereby increasing market acceptance.
