Chinese PV manufacturer Trinasolar has launched its Vertex N Shield photovoltaic module in North America. It is designed primarily for commercial and industrial (C&I) and utility-scale solar projects.
The module is designed for performance in a climates with increasingly severe hail storms and shifting wind loads that impact project insurance premiums and long-term asset bankability.
The Shield line is its equipped with a dual-glass assembly featuring reinforced glass with a surface compression stress exceeding 69 MPa. The design delivers an impact energy resistance that is 2.5 times higher than conventional PV hardware.
The mechanical upgrades allow the modules to withstand severe hail impacts, passing certifications for direct strikes from 55 mm (2.1-inch) diameter hailstones at terminal velocities of 33.9 m/s, as well as up to 75 mm (3-inch) hailstones hitting the glass surface at a 45-degree angle.
Beyond hail impact resistance, the structural frame layout has been designed to handle complex wind and snow loading conditions across diversified terrain profiles:
The electrical characteristics of the Vertex N Shield line mirror the performance metrics of Trinasolar’s existing medium-format n-type portfolio, utilizing a 210R rectangular cell structure across a 132-cell layout.
Operating on an n-type tunnel oxide passivated contact (TOPCon) platform, the flagship module features a peak power output of 620 W with a maximum module efficiency rating of 23.0%. The lower temperature coefficient of -0.29%/°C ensures sustained performance in elevated ambient thermal environments, while its low-voltage design supports longer string configurations to trim down overall balance of system (BOS) capital costs.

Environmental degradation test sequences from Kiwa PVEL indicate long-term stability of the module under severe field operations. The line has secured safety and longevity certifications covering potential-induced degradation (PID), light-induced degradation (LID), and light- and elevated temperature-induced degradation (LeTID), along with accelerated environmental exposure testing for salt mist, ammonia, and high-density dust.
The modules carry a UL 61730 Fire Type 30 designation with comprehensive Class A performance metrics across standard fire evaluations.
Trina backs the module with a 30-year linear performance guarantee, limiting the first-year power degradation to 1.0% and enforcing an annual drop-off ceiling of 0.4% from years 2 through 30.
