Recently, the internationally authoritative testing and certification body TÜV Rheinland Group (hereinafter referred to as TÜV Rheinland) officially issued a Product Water Footprint Verification Statement for the TWMNH-66HD photovoltaic module to Tongwei's three module production bases in Sichuan, Yancheng, and Nantong. As the first enterprise in China's PV industry to complete a full lifecycle product verification, Tongwei successfully passed the product water footprint verification compliant with the ISO 14046:2014 international standard, leveraging its full-chain water resource management capability covering "silicon material - silicon ingot - silicon wafer - solar cell - module." This not only infuses its products with distinct sustainability attributes but also sets an industry benchmark for green and low-carbon development in the photovoltaic industry.



Product water footprint is a key indicator for measuring water resource consumption and environmental impact throughout a product's entire lifecycle, encompassing comprehensive accounting scenarios including direct water use in production and indirect water use in the supply chain. By taking the lead in promoting full-chain water footprint verification, Tongwei achieves a comprehensive quantitative assessment of PV module sustainability from two core dimensions: water scarcity footprint (changes in water quantity) and water degradation footprint (changes in water quality). An expert from TÜV Rheinland Greater China's Solar and Commercial Products Services stated, "By identifying and quantifying water footprints through ISO 14046 verification, enterprises can systematically identify water-saving potential and reduce resource consumption risks." Tongwei's practice is precisely a benchmark application of this standard.
The realization of this Product Water Footprint Verification Statement marks another milestone achievement for Tongwei in its deep commitment to sustainable development. By integrating green indicators such as water footprint into its product sustainability value system, Tongwei has successfully endowed its products with distinct labels of being environmentally friendly, ESG-compliant, and socially responsible. This not only highlights the brand's green development value but also injects a green driving force into leveraging sustainability attributes to enhance product market competitiveness.
Relying on its "Strategy-Stewardship-Solution" ("3S") management system, Tongwei accurately and rapidly responds to financial market disclosure rules, customer green procurement demands, and government regulatory requirements, while actively engaging in exchanges and cooperation with international organizations and collaborating with domestic industry alliances for synergistic development. From technological innovation to full-chain collaboration, from self-breakthroughs to industry empowerment, Tongwei continuously enhances its brand influence and promotes the effective implementation of its sustainable development strategy through a series of comprehensive, multi-level practical initiatives. It achieves resonance between product value and green development, putting into action the corporate vision of "For Better Life."
