International Recognition of Strength Once Again! HY SOLAR HT series high-efficiency modules have successfully passed the stringent testing and certification of TÜV NORD IEC TS 63209-1:2021. As an important international testing standard for verifying photovoltaic module reliability, this achievement not only provides authoritative endorsement for the long-term stability of HY SOLAR's products but also reaffirms HY SOLAR's leading capabilities and sense of responsibility in high-quality manufacturing.

IEC TS 63209-1:2021, issued by the International Electrotechnical Commission (IEC) in 2021, is an international standard specifically developed for extended stress testing of photovoltaic modules. As an advanced version of IEC 61215 and IEC 61730, it further enhances testing intensity and verification dimensions beyond the original foundation, imposing stricter assessment requirements on ground-mounted photovoltaic modules. By extending stress durations, increasing cycle counts, and superimposing extreme environmental conditions such as high temperature, damp heat, mechanical load, and UV irradiation, this standard more realistically simulates the operational conditions throughout a power plant's entire lifecycle. Successfully passing this certification signifies that HY SOLAR's HT series high-efficiency modules can not only meet conventional application scenarios but also maintain stable performance in complex and variable climates and environments, providing power plant owners with more deterministic long-term return guarantees.

The exceptional quality of HY SOLAR HT series high-efficiency modules stems from the synergistic advantages of the integrated industry chain and the continuous empowerment of its intelligent manufacturing system. Leveraging the integrated strengths across "silicon materials – wafers – cells – modules," every stage of module production achieves strict control and efficient connectivity, ensuring stable quality from the source. Meanwhile, smart factories employ digital monitoring and precision manufacturing throughout the entire process, enabling real-time control and traceability to guarantee long-term reliability in product consistency and stability. With leading technological prowess, the HT series modules demonstrate outstanding advantages in high efficiency and high power output, making them fully adaptable to diverse application scenarios. It is precisely this dual drive of full-chain synergy and intelligent manufacturing upgrades that enables HY SOLAR's modules to continuously maintain industry-leading performance in efficiency, reliability, and adaptability, providing customers with high-efficiency, stable, and trustworthy green energy solutions.

This successful certification against TÜV NORD IEC TS 63209-1:2021 not only reaffirms the reliability and stability of HY SOLAR's products but also demonstrates the company's firm commitment to high-quality development. Looking ahead, HY SOLAR will continue to prioritize technological innovation as its core driver and green manufacturing as its development foundation, striving to create even more efficient and reliable photovoltaic solutions. Together with global customers, we aim to co-create a clean and sustainable energy future.
