What is EN ISO 31111:2018

EN ISO 31111:2018 is a technical standard that provides guidelines and requirements for the preparation, execution, and reporting of reliability testing of photovoltaic (PV) modules. This standard aims to ensure consistent and reliable performance data, allowing for accurate comparison and evaluation of different PV modules in the market.

Scope and Purpose of EN ISO 31111:2018

The scope of EN ISO 31111:2018 covers various aspects of reliability testing of PV modules. It provides guidance on test parameters, test procedures, measurement techniques, and reporting requirements. The purpose of this standard is to establish a common framework for the assessment of the reliability of PV modules under specific operating conditions and environments. By adhering to the guidelines set by EN ISO 31111:2018, manufacturers can ensure the quality and reliability of their products, while consumers can make informed decisions based on standardized performance data.

Key Requirements of EN ISO 31111:2018

EN ISO 31111:2018 outlines several key requirements that need to be met during the reliability testing of PV modules. These include:

Stability Test: PV modules are subjected to prolonged exposure to environmental factors such as temperature, humidity, and UV radiation to evaluate their long-term performance.

Climate Test: PV modules are exposed to varying climatic conditions, including extreme temperatures, high winds, and salt spray, to assess their resistance to harsh environments.

Mechanical Load Test: PV modules are subjected to mechanical stress, such as wind pressure and impact, to evaluate their structural integrity and robustness.

Electrical Insulation Test: The ability of PV modules to withstand electrical stress and maintain proper insulation is assessed.

Durability Test: PV modules are subjected to accelerated aging tests, simulating several years of field exposure within a shorter time period, to predict their long-term performance and reliability.

Benefits of EN ISO 31111:2018 Compliance

Compliance with EN ISO 31111:2018 offers several benefits to both manufacturers and end-users. For manufacturers, adherence to this standard ensures consistent quality, reliable performance, and enhanced market competitiveness for their PV modules. By meeting the requirements of EN ISO 31111:2018, manufacturers can gain customers' trust and confidence in their products.

For end-users, EN ISO 31111:2018 compliance provides assurance regarding the quality and reliability of the purchased PV modules. It allows users to make more informed decisions based on standardized and comparable performance data. This standard also promotes transparency in the PV industry, establishing a level playing field for manufacturers and facilitating fair competition.
