What is EN ISO 11901:2012?

EN ISO 11901:2012 is a technical standard that outlines the requirements for performance testing in laboratory and field conditions of solar collectors. This standard encompasses various aspects of solar thermal energy, including materials, design, and performance evaluation.

Materials and Design Requirements

One of the key areas covered by EN ISO 11901:2012 is the specification of materials used in solar collectors. The standard defines the necessary material properties, such as durability, resistance to humidity and temperature variations, and compatibility with heat transfer fluids. Additionally, it provides guidelines on the design criteria for solar collectors, ensuring their ability to withstand environmental factors.

Performance Testing

EN ISO 11901:2012 also establishes procedures for evaluating the performance of solar collectors. It lays out specific test methods that measure parameters like thermal efficiency, heat loss coefficient, and pressure drop. These tests help manufacturers, consumers, and regulatory bodies ensure that solar collectors meet required performance standards.

Benefits and Industry Impact

The adoption of EN ISO 11901:2012 has several benefits, both for the industry and consumers. By providing standardized testing procedures, it promotes fair competition among solar collector manufacturers, ensuring transparency and reliability in product performance claims. Furthermore, compliance with this standard helps to enhance market acceptance and consumer confidence in solar thermal energy systems.
