The panels use Trina's proprietary rectangular 210R wafer format, allowing optimal use of the module surface without excessively increasing weight or dimensions. Thanks to **half-cut cell technology**, cells are split in half, reducing power losses from partial shading and lowering the risk of hot-spots, which extends the lifespan of the installation. The use of **non-destructive cell cutting** minimizes the risk of microcracks that, in conventional modules, can lead to gradual power degradation over time. The multi-busbar metallization grid improves current collection and reduces series resistance, translating into a real increase in energy yield. The NE19R series also stands out for its **low first-year power degradation**, characteristic of n-type technology, resulting in a lower levelized cost of energy (LCOE) over the system's lifetime. This solution is aimed at commercial and industrial investors seeking panels with high power density, good compatibility with existing mounting systems, and predictable, long-term performance. Its solid construction and proven cell architecture make this series a competitive alternative to conventional PERC modules. ## Notable figures - Efficiency of 23.8% is 1.0pp above the \*\*TOPCon 600-650W\*\* median (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 27.9 kg, this panel is 4.8 kg lighter than \*\*TOPCon 600-650W\*\* median (32.7 kg) - easier handling during installation - Ranked #433 out of 14005 panels for efficiency in the database ## Questions ### What is n-type i-TOPCon technology and how does it differ from PERC? N-type i-TOPCon cells feature a thin passivating oxide layer on the rear side of the silicon wafer, reducing recombination losses. Compared to conventional p-type PERC cells, TOPCon delivers higher efficiency (up to 24.1%) and slower power degradation over time, resulting in higher energy yield across the system's lifetime. ### How long is the warranty on Trina Vertex N TSM-NE19R panels? Trina Solar backs the NE19R series with a 12-year product warranty and a 25-year power warranty, guaranteeing at least 99% of nominal power after the first year and 89.4% after 25 years. This is standard for premium n-type modules and one of the longer coverage periods available in the C&I segment. ### Are Vertex N TSM-NE19R panels bifacial? No, the Vertex N TSM-NE19R series is a monofacial module — power is generated only from the front side. Trina Solar offers separate bifacial series for projects that benefit from reflected-light gain, such as installations on light-colored roofs or ground-mount systems. ### How large and heavy are TSM-NE19R panels, and are they suitable for commercial roofs? The panel measures 2382×1134×30 mm and weighs 27.9 kg at up to 650 Wp, giving a high power density per square meter. This design makes it well suited for commercial and industrial roofs with limited load capacity, while the standard 132-cell format ensures compatibility with typical mounting systems. ### Do TSM-NE19R panels perform well in high temperatures? Yes. The temperature coefficient of Pmax is -0.29%/°C, lower than typical PERC panels (usually -0.35% to -0.40%/°C). This means a smaller output drop during hot summer operating temperatures and more stable energy production in climates with wide temperature swings. ### How do half-cut cells and non-destructive cutting improve panel durability? Half-cut technology splits each cell into two halves, reducing current losses and limiting hot-spot risk during partial shading, such as from a chimney or fallen leaves. Non-destructive laser cutting minimizes silicon microcracks that can occur during manufacturing, lowering the risk of gradual power loss over the panel's operating life. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/b67806c64d4b227d57871f20.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, +1.4 pp, +5 yr warranty | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +35 W, +1.4 pp, +5 yr warranty | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +30 W, +1.2 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, +1.2 pp, +5 yr warranty | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +50 W, heavier, +1.1 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, +1.0 pp, +5 yr warranty | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | Cooler, +1.0 pp, +5 yr warranty | | [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, heavier, -8.3 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, heavier, -8.1 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, heavier, -7.9 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, heavier, -3.6 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, heavier, -3.5 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +55 W, heavier, +1.2 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | Heavier, +1.0 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/trina-solar-tsm-ne19r-645 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
