Industry’s First Batch! Xinyi Solar Receives Two National-Level Authoritative Test Certificates from CPVT
During the 19th SNEC SMART ENERGY EXPO 2026, Xinyi Solar’s high-transmittance coated glass received the industry’s first batch “Test Certificate for Energy Efficiency Grade (Mandatory National Standard) Compliance Verification for Crystalline Silicon PV Modules (Raw and Auxiliary Materials)” and the industry’s first “Test Certificate for Conformity to Mandatory National Standards and System Fire Performance Verification” issued by CPVT. The acquisition of these two prestigious national-level certificates serves as authoritative validation of Xinyi Solar’s long-standing commitment to high standards and rigorous requirements, further solidifying its benchmark status in the photovoltaic glass sector.
As China’s first national-level PV quality inspection center, CPVT is renowned in the industry for its rigorous testing standards and meticulous processes, enjoying high credibility. Xinyi Solar’s high-transmittance coated glass, having undergone comprehensive and stringent testing in accordance with the technical specifications of the “Test Certificate for Energy Efficiency Grade (Mandatory National Standard) Compliance Verification for Crystalline Silicon PV Modules (Raw and Auxiliary Materials),” has become one of the first batch PV glass manufacturers to achieve the highest grade (Grade 1 energy efficiency) certification. This certificate focuses on two core metrics:conversion efficiency of photovoltaic modules and stress decay rate of coupling environment. The glass’s superior optical transmittance and weather resistance help enhance module power generation efficiency and long-term reliability, thereby generating higher returns from power generation for end customers.
Additionally, by optimizing the thickness uniformity and glass strength of high-transmittance coated glass, the Company has successfully obtained the first “Test Certificate for Conformity to Mandatory National Standards and System Fire Performance Verification” in the photovoltaic glass category. This testing addresses fire safety concerns in both utility-scale and distributed solar projects, elevating the fire safety rating of photovoltaic systems and providing a solid foundation for the long-term, reliable operation of solar projects.
The successful completion of these two national-level authoritative tests signifies that Xinyi Solar has positioned itself at the forefront of industry standards in both energy efficiency management and fireproof for photovoltaic products. Moving forward, the company will continue to iterate and optimize the performance of photovoltaic glass, aligning with mandatory national standards. It will consistently launch a diverse range of safe and efficient products tailored for ground-mounted solar farms, commercial and industrial distributed solar projects, and residential distributed photovoltaic power system applications. Through these high-standard products, the company aims to enhance the safety and quality of solar projects both domestically and internationally, propelling China’s photovoltaic industry from large-scale expansion toward a new phase of high-quality, standardized development.
