Certification Builds Global Trust
IEC 61215 (performance) and IEC 61730 (safety) are essential benchmarks for photovoltaic modules entering global markets, covering durability, mechanical strength, long-term reliability, and electrical safety. Achieving both certifications demonstrates strong recognition of Suntech’s innovation, manufacturing capabilities, and product quality.
The certification validates the module’s performance in extreme environments, long-term stability, and system-level safety, supporting Suntech’s continued expansion in global markets.
25 Years of Innovation
With 25 years of PV expertise, Suntech continues to advance R&D, with TOPCon 3.0 cell efficiency exceeding 27.5%. The Ultra T 3.0 modules achieve a bifaciality rate of up to 90%, with first-year degradation ≤1% and annual degradation as low as 0.35%, ensuring strong long-term reliability.
Quarter-cut technology reduces operating current and resistive losses, improving power output and heat distribution while minimizing hotspot risks. Compatible with high-density spacing designs, it increases effective light-receiving area and energy yield. With edge passivation and advanced thin-film processes mitigating cutting-related defects, the modules also offer strong performance under low-light conditions and resistance to micro-cracks and mechanical loads, ensuring reliable operation across the lifecycle.
The TÜV Rheinland certification provides strong industry validation of Suntech’s technology roadmap. Moving forward, Suntech will continue advancing N-type and structural innovation to deliver higher-efficiency, more reliable PV solutions, supporting the global energy transition.
