What is IEC 62108 Ed.3:2018?

The International Electrotechnical Commission (IEC) has established standards for various technical industries, including solar photovoltaic (PV) modules. One such standard, known as IEC 62108 Ed.3:2018, specifically deals with the requirements for the design qualification and type approval of concentrator photovoltaic (CPV) modules and assemblies.

Design Qualification and Type Approval

IEC 62108 Ed.3:2018 outlines the necessary procedures and tests that CPV modules must undergo to be deemed reliable and suitable for deployment. The aim is to ensure that these modules meet essential performance characteristics, such as efficiency, durability, and safety, under different operating conditions.

The design qualification process involves subjecting CPV modules and assemblies to a range of environmental stresses, including temperature variations, humidity, and mechanical loads. This testing phase helps evaluate the resilience of the modules in real-world conditions.

Type approval, on the other hand, focuses on verifying compliance with specific performance standards and requirements. This stage ensures that CPV modules meet the necessary industry benchmarks before being approved for mass production and commercial use. Various performance metrics, such as electrical output, spectral response, and power-handling capabilities, are meticulously examined during this evaluation process.

Benefits of IEC 62108 Ed.3:2018

The implementation of IEC 62108 Ed.3:2018 brings numerous benefits to the solar industry and end-users alike.

Firstly, it offers a standardized framework for assessing the quality and reliability of CPV modules. By setting clear criteria and test methods, this standard enables manufacturers, investors, and consumers to make informed decisions about the products they choose or invest in.

Secondly, the compliance with IEC 62108 Ed.3:2018 enhances market confidence. By adhering to these internationally recognized standards, manufacturers can demonstrate their commitment to producing high-quality and reliable CPV modules, which, in turn, creates trust among potential investors and buyers.

Lastly, the implementation of this standard promotes innovation and technological advancement within the solar PV industry. It encourages manufacturers to continuously improve their products' performance and efficiency to meet the stringent requirements set forth by IEC 62108 Ed.3:2018. This, ultimately, benefits both the industry and end-users by driving advancements in renewable energy technology.


IEC 62108 Ed.3:2018 plays a crucial role in ensuring the quality, reliability, and performance of concentrator photovoltaic modules and assemblies. By defining the design qualification process and type approval requirements, it helps manufacturers produce CPV modules that meet international standards. The implementation of this standard brings numerous benefits, including standardized assessment frameworks, enhanced market confidence, and increased innovation within the solar PV industry.
