TL;DR
Trinasolar has launched a 620 W TOPCon ‘Shield’ module designed for North American markets, emphasizing hail, wind, and snow resilience. The product aims to address climate-related risks impacting project durability and economics.
Trinasolar has introduced its 620 W Vertex N Shield photovoltaic module to the North American market, emphasizing enhanced mechanical durability and resilience against extreme weather conditions. The product aims to meet the needs of utility-scale and commercial solar projects facing increasing climate-related risks, such as hail, high winds, and snow loads.
The Vertex N Shield module features a dual-glass architecture with reinforced glass that achieves surface compression stress above 69 MPa, making it approximately 2.5 times more impact-resistant than conventional PV modules, according to Trinasolar. It is engineered to withstand direct impacts from 55 mm hailstones at velocities of 33.9 m/s and 75 mm hail impacts at a 45-degree angle. The module also supports static wind loads of +7,000 Pa downward and -5,000 Pa uplift, suitable for deployment in hurricane-prone coastal areas. Additionally, it can endure asymmetrical snow loads of up to +6,600 Pa, corresponding to nearly 7.2 feet of snow accumulation, relevant for high-altitude and northern regions.
Electrically, the module maintains a peak power output of 620 W, with an efficiency of 23.0%, utilizing a 132-half-cut cell design on an i-TOPCon monocrystalline platform. Its dimensions are 2382 mm by 1134 mm, weighing 39.7 kg, with an open-circuit voltage of 49.6 V and short-circuit current of 15.91 A. The module has undergone environmental testing with Kiwa PVEL, validating resistance against PID, LID, LeTID, as well as salt mist, ammonia, and high-dust conditions. It carries UL 61730 Fire Type 30 certification and achieves Class A fire safety standards, supporting North American compliance. Trinasolar offers a 30-year warranty on performance, emphasizing its focus on long-term durability and project economics.
Enhanced Durability Meets Growing Climate Risks in Solar Projects
The launch of the Vertex N Shield module signifies a strategic response to the increasing frequency of extreme weather events impacting solar installations. Its high impact and mechanical resilience aim to reduce operational risks, lower insurance premiums, and improve long-term project bankability in vulnerable regions. As climate volatility continues to influence project design and economics, such resilient modules are becoming essential for developers seeking reliable energy generation and asset longevity.
