What is EN 61646:2018

EN 61646:2018 is a technical standard that sets requirements for the design and manufacture of thin-film photovoltaic (PV) modules. It aims to ensure the quality, reliability, and safety of these modules. This article provides a thorough of EN 61646:2018, exploring its scope, key requirements, and implications for the PV industry.

The Scope of EN 61646:2018

EN 61646:2018 applies to thin-film PV modules based on semiconductor materials such as amorphous silicon, copper indium diselenide, and cadmium telluride. It covers modules intended for installation on roofs, facades, or other structures, both in grid-connected and standalone applications. The standard addresses various aspects, including electrical characteristics, structural integrity, environmental testing, and safety requirements.

Key Requirements of EN 61646:2018

The standard defines specific requirements that thin-film PV modules must meet to achieve compliance. These requirements include electrical performance, mechanical strength, durability, and environmental stability. For example, the modules should be able to withstand mechanical stressors like wind loads and snow loads, and they should maintain their electrical output under various temperature and humidity conditions.

Moreover, EN 61646:2018 outlines testing procedures and criteria to evaluate the module's performance. This includes tests for electrical insulation, fire resistance, and resistance to environmental factors like moisture, UV radiation, and salt mist. Compliance with these requirements ensures that the modules can perform reliably throughout their operational lifetime.

Implications for the PV Industry

EN 61646:2018 has several notable implications for manufacturers, installers, and consumers in the PV industry. Firstly, compliance with the standard demonstrates a commitment to producing high-quality and reliable PV modules. This can enhance consumer confidence and facilitate market access.

Secondly, EN 61646:2018 promotes uniformity and harmonization in module design and testing methods. This simplifies the certification process and enables cross-border trade of PV modules within the European Union and other countries that recognize the standard.

Lastly, the standard encourages continuous improvement in PV technology. As it evolves, EN 61646:2018 incorporates advancements and feedback from industry stakeholders, ensuring that it remains relevant and addresses emerging challenges.
