Trinasolar announced that its Vertex N Shield module has been honored with the PV Module Comprehensive Reliability Award at the 11th TÜV Rheinland “All Quality Matters” Solar & ESS Congress 2025, held on September 24, 2025, highlighting the exceptional reliability of Trinasolar’s modules.
TÜV Rheinland assessed modules across five dimensions, including thermal cycling, mechanical load and dynamic stress, UV exposure and humidity-freeze, damp heat, and PID. The Vertex N Shield module achieved an impressive score of 94, ranking first in every indicator, outperforming other competing modules, and fully validating its long-term reliability.
“It has been ten years since Trinasolar began advancing TOPCon technology in 2015,” Said Lei Gao, Director of Global Cell and Solar Product Management at Trinasolar. “Our TOPCon module winning the 2025 ‘Comprehensive Reliability Award’ is great recognition. Trinasolar will continue to provide more reliable products and solutions for customers.”
The award-winning Vertex N Shield module features advanced TOPCon technology. Its glass is 25% thicker and 2.5 times more impact-resistant than conventional modules. It is certified by RETC to withstand hail measuring 75mm at a 60° angle during severe hailstorms. The module’s frame design increases load-bearing capacity, which enhances PV module stability and reliability. The module's high reliability had been confirmed by RETC in June, earning it the title of “High Achiever” in multiple categories, including TC600, DH2000, SDML, and PID.
The Vertex N Shield module is part of Trinasolar’s TOPCon module line and plays a role in the shield extreme climate solution, which was introduced in March 2025. The Vertex N Shield module is part of Trinasolar’s TOPCon module line of extreme climate solutions, which was introduced in March 2025. This solution pioneered a new era of scenario-based solutions. In addition to TOPCon modules, the extreme climate solution features a smart tracking system that protects PV plants and maintains stable operation. This approach increases revenue while lowering BOS and LCOE. Trinasolar offers smart PV and energy storage solutions for a variety of settings, such as desert and offshore regions, and has received recognition for its work. In addition to maintaining BNEF Tier 1 status both for modules and storage, it was recently named in S&P Global Commodity Insights’ premier list of Tier 1 Companies for PV modules and energy storage systems.
