At the Greater China Advanced Solar & Energy Storage Technology Symposium held in Changzhou by TÜV Rheinland, Hondol Material was among the first group of companies to receive the newly launched IEC 62788-2-1:2023 certification for photovoltaic module front and backsheets, awarded by TÜV Rheinland.
As a world-renowned independent testing, inspection, and certification organization, TÜV Rheinland hosted this symposium under the theme “Exploring Green Sustainability, Pioneering a New Future for Solar and Storage.” The event brought together leading global representatives from photovoltaic and energy storage technology R&D and manufacturing enterprises to discuss new technologies, standards, and applications related to photovoltaic modules, storage and charging systems, materials, components, and more.
Hondol Material has always been committed to addressing pain points in the renewable energy sector through technological innovation. By continuously increasing R&D investment and advancing technological capabilities, the company has achieved a series of significant breakthroughs and results across its four major product lines: photovoltaic backsheets, encapsulation films, soft glass, and fluoropolymer films. Being among the first to obtain the new standard certification signifies that Hondol’s backsheet technology meets the latest international requirements and serves as a strong endorsement of the company’s independent R&D capabilities and technical expertise.
After five years of compilation and discussion, the IEC 62788-2-1:2023 standard for front and backsheets of photovoltaic modules was officially released in August 2023. The standard introduces more precise and stringent evaluation criteria for photovoltaic backsheets, including an increase in the total irradiation requirement for ultraviolet aging tests. It also mandates thermal failure testing for materials in each layer structure, while linking insulation tests to effective insulation thickness.
IEC 62788-2-1:2023 is the industry’s first international standard specifically addressing safety requirements for front and backsheets used in photovoltaic modules. Recognized as the most comprehensive and authoritative evaluation framework for such products, it marks the achievement of full standardization and unification in photovoltaic backsheet specifications. This standard will be directly referenced in IEC 61730-1.
Under the guidance of the new industry standard, Hondol Material will continue to drive innovation in photovoltaic backsheet technology, consistently enhancing product performance and reliability. The company will further strengthen strict control over the production processes of photovoltaic backsheets to ensure compliance with the highest quality standards, providing superior solutions for global photovoltaic module manufacturers. Grandshine will also maintain close collaboration with domestic and international partners to jointly advance the innovation and development of photovoltaic backsheet technology, contributing more significantly to the achievement of green and sustainable development.
