At the core of the series is the patented **i-TOPCon Ultra technology**, which delivers continuous efficiency gains through reduced contact resistance, enhanced rear-side reflection, and repaired cell edge quality. The panels feature a **bifacial dual-glass construction** that captures additional rear-side energy of up to 20%, depending on ground albedo - a benefit especially valued by utility-scale solar farm developers and installations on bright, reflective surfaces. A unique **short-edge frame design that limits soiling** minimizes dust and snow buildup at low-tilt mounting angles, meaningfully lowering cleaning and maintenance costs while boosting average energy output. The modules also offer **high resistance to micro-cracks** thanks to non-destructive cell-cutting technology, along with certified resistance to salt, ammonia, sand, PID, LID, and LeTID, making them well suited to harsh climate conditions. The series is backed by a **30-year power warranty**, giving investors confidence in the long-term profitability of their investment. ## Notable figures - At 23.1% efficiency, this panel is on par with typical \*\*TOPCon 600-650W\*\* modules - 231.4 W/m² power density - 3.7 W/m² more than \*\*TOPCon 600-650W\*\* median (227.7 W/m²), more power per roof area - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 600-650W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - In the top 11% for efficiency among all TOPCon panels ## Questions ### How much extra energy can Trina Vertex N i-TOPCon Ultra panels generate thanks to their bifacial design? Thanks to the dual-glass bifacial construction, Vertex N i-TOPCon Ultra panels generate extra energy from the rear side of the module - depending on ground albedo, the gain can reach up to 20%. The best results are achieved on bright, reflective surfaces such as white gravel, concrete, or snow, which is why this design is especially recommended for utility-scale PV farms and ground-mount installations, though it also performs well on flat commercial roofs at the right tilt angle. ### What is the difference between i-TOPCon Ultra technology and standard TOPCon or PERC? i-TOPCon Ultra is Trina Solar's patented enhancement of classic TOPCon technology, achieved through reduced contact resistance, improved rear-surface reflection, and edge-quality repair after cell cutting. As a result, the modules reach higher conversion efficiency (up to about 23.7%) and lower power loss over time compared to older PERC technology, while maintaining strong resistance to LID and LeTID degradation. ### What warranty comes with Trina Solar Vertex N i-TOPCon Ultra panels? The manufacturer backs the Vertex N i-TOPCon Ultra series with a 12-year product warranty and a 30-year linear power output warranty. This means that even after three decades of operation, the panel should retain the guaranteed percentage of its initial power output, giving investors confidence in the long-term profitability of installations using modules rated up to 640 Wp. ### Are Vertex N i-TOPCon Ultra panels suitable for a residential roof, or only for solar farms? Modules rated up to 640 Wp with large-format cells are primarily optimized for utility-scale installations - solar farms and commercial or industrial buildings - where maximizing power output from limited space matters most. Due to their size and weight, mounting them on a typical sloped residential roof can be challenging, so it's worth checking the roof's load capacity with an installer beforehand. ### What does the anti-soiling edge frame on Vertex N i-TOPCon Ultra panels do? The specially designed frame reduces the buildup of dust, sand, and snow along the module's lower edge, especially at low mounting angles where soiling most often shades the cells. This lowers how often panels need cleaning and reduces power losses from edge shading, resulting in higher average energy yield and lower long-term maintenance costs for the installation. ### Are Trina Vertex N i-TOPCon Ultra panels resistant to salt, ammonia, and other harsh conditions? Yes, the series is certified for resistance to salt corrosion and ammonia exposure, making it suitable for coastal installations and sites near agricultural land. The panels are also certified for resistance to PID, LID, and LeTID, and the non-destructive cell-cutting technology improves resistance to microcracks - an important factor during transport and installation in demanding terrain. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DT-M-0113-G-EN_A_Datasheet_Vertex_NEG19RC70_2025_A-d3dc71a8ff5f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.1 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +50 W, lighter, +1.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +1.9 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +45 W, lighter, +1.7 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +45 W, lighter, +1.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +1.7 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +45 W, cooler, +1.7 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 | -205 W, -7.6 pp, -5 yr warranty | | [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 | -200 W, -7.4 pp, -5 yr warranty | | [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 | -195 W, -7.2 pp, -5 yr warranty | | [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 | -80 W, -2.9 pp, -5 yr warranty | | [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 | -75 W, -2.8 pp, -5 yr warranty | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +55 W, lighter, +2.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +75 W, cooler, +1.9 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +70 W, cooler, +1.8 pp | --- Source: https://comparepv.com/panel/trina-solar-tsm-neg19rc-70-625 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.
