Trinasolar has launched a new 620 W TOPCon ‘Shield’ photovoltaic module in North America. It offers enhanced mechanical resilience against hail, wind, and snow loads, targeting utility-scale and commercial solar projects in climate-challenging regions.
Trinasolar has officially launched its 620 W TOPCon ‘Shield’ photovoltaic module in North America, designed to withstand extreme weather conditions such as hail, high winds, and heavy snow loads. This product aims to meet the needs of utility-scale and commercial solar projects vulnerable to climate-related risks, marking a significant step in enhancing solar asset resilience in the region.
The new module features a dual-glass architecture with reinforced glass that achieves a surface compression stress above 69 MPa, providing impact resistance approximately 2.5 times higher than conventional PV modules, according to Trinasolar. It is engineered to withstand direct strikes from 55 mm hailstones at velocities of 33.9 m/s and impacts from 75 mm hail at a 45-degree angle, positioning it among the most hail-resistant modules targeting utility-scale applications.
Beyond hail protection, the module is certified for static wind loads of +7,000 Pa downward and -5,000 Pa uplift, suitable for deployment in high-wind and hurricane-prone areas. It also supports asymmetrical snow loads up to +6,600 Pa, equivalent to nearly 7.2 feet of snow, making it applicable for mountainous and high-latitude regions. Its structural performance remains certified at +3,600 Pa and -3,000 Pa on tracker systems, even with reduced purlin support, aligning with modern single-axis tracker designs.
Electrically, the module maintains a 620 W peak power output, with a maximum efficiency of 23.0%, built on a 210R rectangular cell layout with half-cut cells on an i-TOPCon monocrystalline platform. It measures 2382 mm × 1134 mm × 30 mm, weighs 39.7 kg, and offers an open-circuit voltage of 49.6 V and a short-circuit current of 15.91 A. The module has undergone environmental stress testing and is certified for long-term durability, including UL 61730 Fire Type 30 and Class A fire safety standards, with a 30-year performance warranty.
Enhanced Resilience Meets Utility-Scale Needs
The launch of the Vertex N Shield module signifies a strategic move by Trinasolar to address growing climate-related risks faced by solar projects in North America. Its high impact resistance and structural robustness aim to reduce damage from extreme weather, potentially lowering insurance costs and improving long-term project viability. As climate volatility increases, such durable modules are becoming essential for developers seeking reliable, long-lasting solar assets in challenging environments.

Growing Weather Risks Drive Demand for Durable Modules
In recent years, North American solar developers have faced increasing challenges from severe weather events, including hailstorms, hurricanes, and heavy snowfall. These conditions threaten asset integrity and can significantly impact project economics. Manufacturers are responding by developing more mechanically resilient modules. Trinasolar’s introduction of the Vertex N Shield aligns with industry trends toward weather-hardened PV solutions, especially as insurance premiums rise and project bankability becomes more dependent on resilience measures.
“The Vertex N Shield’s impact resistance is approximately 2.5 times higher than standard modules, marking a significant advancement in weather durability.”
