What is EN 61646:2018?

EN 61646:2018 is a professional technical standard that specifies the testing and requirements for thin-film terrestrial photovoltaic (PV) modules. This standard ensures that PV modules meet the necessary quality and safety standards for reliable and efficient operation in various applications.

The Significance of EN 61646:2018

The adoption of EN 61646:2018 plays a crucial role in the PV industry. By complying with this standard, manufacturers can demonstrate the performance, durability, and reliability of their PV modules. With consistent testing methodologies outlined in EN 61646:2018, end-users can have confidence in the quality of the modules they are utilizing.

EN 61646:2018 also helps facilitate international trade of PV modules, as it provides a common set of standards that manufacturers from different countries can adhere to. This harmonization allows for easier comparison and evaluation of products in the global market, enhancing transparency and promoting fair competition.

Testing Procedures and Requirements

EN 61646:2018 outlines comprehensive testing procedures and requirements for PV modules. These include electrical, thermal, mechanical, and environmental tests, ensuring that the modules can withstand various operating conditions.

Electrical tests evaluate the module's output power, voltage, current, and performance under different lighting conditions. Thermal tests assess the module's ability to handle temperature variations and exposure to heat sources. Mechanical tests focus on the mechanical robustness of the module, including its resistance to wind, snow, and impact forces.

Environmental tests evaluate the module's capability to withstand prolonged exposure to moisture, ultraviolet light, and other environmental factors. These tests simulate real-world conditions to ensure the long-term reliability and durability of the modules.

Compliance and Certification

PV module manufacturers seeking compliance with EN 61646:2018 must subject their products to rigorous testing by accredited laboratories. These tests are performed according to the specific requirements outlined in the standard. Upon successful completion of the tests, manufacturers can obtain certification that validates their module's compliance with the standard.

Compliance with EN 61646:2018 not only demonstrates a manufacturer's commitment to quality and safety but also helps build trust among customers and stakeholders. It ensures that PV modules meet the necessary performance and durability standards, leading to improved reliability and customer satisfaction.
