The series stands out for its **advanced hail resistance**, verified through testing that withstands hailstone impacts up to 75 mm in diameter - thanks to reinforced tempered glass, the module absorbs impact energy up to 2.5 times greater than conventional panels. The panels are built on **i-TOPCon technology** n-type platform, using rectangular **210R half-cut cells**, which translates into stable performance and slower degradation over time compared to older PERC solutions. The construction also delivers **high resistance to mechanical loads**, making the series suitable both for large ground-mounted solar farms and installations in regions with harsh climate conditions, including hurricane-prone areas. A low temperature coefficient and low-voltage design enable longer string configurations, which helps reduce cabling and racking costs (BoS) and ultimately **lower the LCOE** of the entire installation. This solution is aimed primarily at investors and installers looking for panels that combine high power output with real long-term investment security. ## Notable figures - 23.9% module efficiency - 1.1pp better than the \*\*TOPCon 600-650W\*\* median of 22.8% - At 238.8 W/m² power density, this panel generates 11.1 W/m² more per unit area than \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 600-650W\*\* median - At 39.7 kg, this panel is 7.0 kg heavier than the \*\*TOPCon 600-650W\*\* median (32.7 kg) - more demanding for installation crews - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### How does the Trina Solar Vertex N Shield series differ from standard solar panels? The key difference is enhanced resistance to extreme weather conditions. Vertex N Shield modules have passed hail resistance tests with hailstones up to 75 mm in diameter, and thanks to a reinforced tempered glass they can withstand up to 2.5 times more impact energy than conventional panels. They also feature n-type i-TOPCon technology with 210R half-cut cells, delivering higher efficiency and slower degradation than older PERC panels. ### What warranty comes with Trina Solar Vertex N Shield panels? The manufacturer provides a 12-year product warranty and a 30-year power performance warranty. This means the panel maintains its guaranteed output level for three decades, while the first 12 years also cover material and manufacturing defects. This is a standard offering for tier 1 products such as Trina Solar. ### Are Vertex N Shield panels bifacial, and is it worth using that feature? Yes, the Vertex N Shield series consists of bifacial modules that generate power from both the front and rear side of the panel. With proper installation, such as mounting over a light-colored surface or on an elevated structure, this can boost energy yield by several to over a dozen percent compared to a standard monofacial panel, without increasing the installation footprint. ### What is the maximum power output of the Trina Vertex N Shield panel and what installations is it suited for? Panels in this series reach a maximum power of up to 645 Wp. The high power output per module combined with strong mechanical durability makes this series particularly suited for large ground-mounted solar farms and installations in harsh climate regions, including areas exposed to strong winds and hurricanes, where both performance and structural resilience matter. ### What is i-TOPCon technology in Vertex N Shield panels and how does it differ from PERC? i-TOPCon is an n-type cell technology that uses an additional passivation layer to reduce energy losses on the cell surface. In practice, this results in higher initial efficiency and significantly slower power degradation over time compared to older p-type PERC technology. Vertex N Shield uses rectangular 210R cells in a half-cut layout, further improving operational stability and resistance to microcracks. ### Can Vertex N Shield panels help lower the total cost of a solar installation? Yes, thanks to a low temperature coefficient and low-voltage design, longer strings of panels can be built. This reduces the number of inverters needed, shortens cabling, and lowers demand for balance of system (BoS) components, directly reducing the LCOE of the entire installation, particularly in large utility-scale projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DT-M-0117-G-EN-A-Datasheet_Vertex_NED19RC20_2025_A-e929b9c8e9ed.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +1.3 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +35 W, lighter, +1.3 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +30 W, lighter, +1.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +1.1 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +50 W, lighter, +1.0 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +0.9 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | Cooler, lighter, +0.9 pp | | [Trina Solar TEB-NEGA6ND.48-420 (Silver Grey, RAL9018)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-420-silver-grey-ral9018) | 420 W | -225 W, lighter, -8.4 pp | | [Trina Solar TEB-NEGA6ND.48-425 (Silver Grey, RAL9018)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-425-silver-grey-ral9018) | 425 W | -220 W, lighter, -8.2 pp | | [Trina Solar TEB-NEGA6ND.48-430 (Silver Grey, RAL9018)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-430-silver-grey-ral9018) | 430 W | -215 W, lighter, -8.0 pp | | [Trina Solar TEB-NEGA6ND.48-545 (Green, RAL6001)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-545-green-ral6001) | 545 W | -100 W, lighter, -3.7 pp | | [Trina Solar TEB-NEGA6ND.48-550 (Green, RAL6001)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-550-green-ral6001) | 550 W | -95 W, lighter, -3.6 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +55 W, lighter, +1.1 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | Cooler, lighter, +0.9 pp | --- Source: https://comparepv.com/panel/trina-solar-tsm-ned19rc-20 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
