Its standout feature is the **full-black, cohesive visual design** - uniform black for the cells, frames, and details creates an elegant effect without random color variations, which is important for installations on contemporary homes and premium buildings. Another key advantage is the **dual-glass (glass-glass) construction**, which increases resistance to environmental factors and reduces the risk of damage during operation, especially in challenging conditions. The application of **n-type i-TOPCon cells** helps maintain high efficiency over time and stable energy production, translating to better project profitability. This series is a good choice for homes, small businesses, and projects where a **long warranty period** and minimizing downtime and complaints are important. In practice, it stands out by combining premium aesthetics with technology focused on longevity, not just paper parameters. ## Notable figures - At 22.8% efficiency, this panel is on par with typical \*\*TOPCon 450-500W\*\* modules - At 227.7 W/m² power density, roof space requirements are typical for \*\*TOPCon 450-500W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 450-500W\*\* median - Weight of 21.0 kg (3.0 kg below \*\*TOPCon 450-500W\*\* median of 24.0 kg) allows easier transport and roof mounting - #2714 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the Trina Solar Vertex S+ TSM-NEG9R.25 panel? Panels in this series reach a maximum power output of up to 455 Wp, one of the higher figures among standard-sized modules designed for pitched roofs. This is achieved through n-type TOPCon cell technology with high conversion efficiency, meaning fewer panels are needed to reach a target system capacity on limited roof space. ### Is the Trina Solar Vertex S+ TSM-NEG9R.25 series still available for purchase? This series has been discontinued from active production by Trina Solar and replaced by newer models. It can still be found through some distributors as remaining stock, but availability is limited. Buyers should confirm with the seller that the batch offered still carries full manufacturer warranty coverage and a current compliance certificate. ### What warranty comes with the Trina Vertex S+ TSM-NEG9R.25 panels? The manufacturer provides a 15-year product warranty and a 30-year linear power output warranty. This covers both material and workmanship defects as well as gradual power degradation over the panel's service life. This level of coverage is typical for tier-1 manufacturers and supports a predictable return on investment even after more than a decade of use. ### How does the dual-glass construction in the Vertex S+ differ from standard framed backsheet panels? The dual-glass construction replaces the polymer backsheet with a second layer of glass, significantly increasing the panel's resistance to moisture, corrosion, and cell microcracks. As a result, the module better withstands thermal cycling, hail, and prolonged weather exposure, reducing the risk of power degradation and warranty claims compared to cheaper backsheet-based designs. ### Are the Trina Vertex S+ TSM-NEG9R.25 panels bifacial? No, this series uses monofacial modules rather than bifacial technology. This means the panels generate power only from irradiance hitting the front surface, which is a proven, standard choice for pitched-roof installations where the rear side has no access to reflected light anyway. ### What type of roofs are best suited for panels from this series? The full-black, visually consistent design without noticeable cell or frame color variation makes this series well suited for single-family homes and premium buildings where aesthetics matter. Standard dimensions and the dual-glass construction make installation on typical pitched-roof rafters straightforward, while the high per-panel wattage allows fewer modules to be used on smaller roof areas. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/dt-m-0084-c-datasheet-vertex-s-neg9r-25-en-2024-c-e8115571cfaa.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, cooler, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, cooler, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Trina Solar TSM-DE09R.05-405](https://comparepv.com/panel/trina-solar-tsm-de09r-05-405) | 405 W | -50 W, hotter, -2.5 pp | | [Trina Solar TSM-DE09R.05-410](https://comparepv.com/panel/trina-solar-tsm-de09r-05-410) | 410 W | Hotter, -2.3 pp, -5 yr warranty | | [Trina Solar TSM-DE09R-415](https://comparepv.com/panel/trina-solar-tsm-de09r-415) | 415 W | Hotter, -2.0 pp, -5 yr warranty | | [Trina Solar TSM-DE09R.08-420](https://comparepv.com/panel/trina-solar-tsm-de09r-08-420) | 420 W | Hotter, -1.8 pp, -5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/trina-solar-co-ltd-tsm-neg9r-25-455 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
