BS EN IEC 62788-1-7:2020

Overview

BS EN IEC 62788-1-7:2020 provides essential measurement procedures for evaluating the optical durability of encapsulants used in photovoltaic (PV) modules. This standard is crucial for manufacturers and compliance professionals aiming to ensure the longevity and performance of solar energy systems. The encapsulant materials play a vital role in protecting photovoltaic cells from environmental factors, thus directly influencing the efficiency and lifespan of solar modules.

Key Requirements

The standard outlines specific test procedures designed to assess the optical properties of encapsulants under various conditions. Key requirements include:

• Test Conditions: Detailed specifications on environmental conditions, including temperature and humidity, to simulate real-world exposure.
• Measurement Techniques: Guidelines on the optical measurement methods to be employed, ensuring consistency and reliability in results.
• Data Analysis: Procedures for analysing the data collected, focusing on changes in optical properties over time.
• Reporting: Requirements for documenting the test results, including formats and essential information to be included in the reports.

Implementation Benefits

Adopting BS EN IEC 62788-1-7:2020 offers several practical benefits for manufacturers and stakeholders in the photovoltaic industry:

• Quality Assurance: By following the standard, manufacturers can ensure that their encapsulants meet rigorous quality benchmarks, enhancing product reliability.
• Market Confidence: Compliance with this standard can improve market confidence in products, as it demonstrates a commitment to quality and performance.
• Risk Mitigation: Understanding the optical durability of encapsulants helps in identifying potential failures early, reducing warranty claims and associated costs.
• Innovation Facilitation: The standard encourages research and development of new materials by providing a clear framework for testing and evaluation.

Compliance Value

Compliance with BS EN IEC 62788-1-7:2020 is not only beneficial for manufacturers but also essential for meeting regulatory requirements in the energy sector. Adhering to this standard can lead to:

• Regulatory Compliance: Meeting national and international regulations regarding the performance and safety of photovoltaic systems.
• Enhanced Reputation: Companies that comply with recognised standards are often viewed more favourably by customers and regulatory bodies.
• Access to Markets: Compliance can be a prerequisite for entering certain markets, particularly in regions with stringent energy regulations.

In conclusion, BS EN IEC 62788-1-7:2020 serves as a critical framework for assessing the optical durability of encapsulants in photovoltaic modules. By implementing the procedures outlined in this standard, manufacturers can ensure high-quality products that meet both market demands and regulatory requirements.
