At its core lies the patented **n-type i-TOPCon Ultra** technology, which delivers stable cell performance throughout the system's lifetime by reducing carrier recombination at the metal contact and optimizing edge passivation. The panel features a **dual-glass** construction, resistant to hailstone impact up to 55 mm and mechanical loads reaching thousands of pascals, making it a solution for installers seeking durability beyond the market standard. Its clean, uniform surface with no visible gaps between cells makes the module equally suited for residential rooftops and commercial installations. Thanks to low power degradation in the first year and throughout subsequent years of operation, the series delivers higher long-term energy yield and lower system costs. The whole series is backed by a **30-year linear performance warranty**, giving investors confidence in the project's long-term profitability. This is a proposition for those who expect not only high efficiency but also module resilience against extreme weather events. ## Notable figures - Efficiency of 23.0% matches the \*\*TOPCon 450-500W\*\* median - Power density of 230.2 W/m² packs 5.0 W/m² more into the same footprint vs \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 450-500W\*\* median - Weight of 27.0 kg is 3.0 kg above \*\*TOPCon 450-500W\*\* median (24.0 kg) - verify structural support - Ranked #1919 out of 14005 panels for efficiency in the database ## Questions ### Is the Trina Solar Vertex S+ Shield i-TOPCon Ultra series still available for purchase? The Vertex S+ Shield i-TOPCon Ultra series has been discontinued by Trina Solar and replaced by newer models. Remaining stock may still be available through distributors, but quantities are limited. Anyone planning to expand an existing installation with additional modules from this series should act quickly, as matching this exact model may become impossible once remaining inventory sells out. ### What warranty comes with the Trina Solar Vertex S+ Shield i-TOPCon Ultra 470 Wp modules? The manufacturer provides a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power warranty. This means the panel guarantees a minimum percentage of its rated power output even after three decades of use. For installers and investors, this is a key factor when calculating return on investment over a 25-30 year horizon. ### What is n-type i-TOPCon Ultra technology and how does it differ from standard PERC panels? i-TOPCon Ultra is a patented n-type cell technology that reduces carrier recombination at the metal contact and optimizes edge passivation. In practice, this means lower internal energy losses and more stable module performance throughout its service life compared to older p-type PERC cells. The result is higher efficiency, lower annual degradation, and greater real-world energy yield over the long term. ### Are the Vertex S+ Shield 470 Wp panels bifacial, and is it worth the extra investment? Yes, this series uses bifacial cells in a glass-glass construction, allowing the rear side to capture reflected radiation as well. Depending on ground albedo, mounting height, and tilt angle, the additional energy gain can range from a few percent to over ten percent. This makes the panels especially effective on light-colored roofs, ground-mount systems, and installations on elevated racking. ### Can the Vertex S+ Shield i-TOPCon Ultra withstand hail and heavy snow loads? Yes, the Shield series was specifically engineered for harsh weather conditions. Its dual-glass construction withstands hailstones up to 55 mm in diameter and mechanical loads in the thousands of pascals generated by strong wind and snow accumulation. This makes it a recommended choice for roofs in mountainous regions or areas prone to extreme weather events. ### Is Trina Solar a Tier 1 manufacturer, and what does that mean for investment security? Yes, Trina Solar is a China-based Tier 1 manufacturer, reflecting financial stability, a long production track record, and product bankability recognized by financing institutions worldwide. For investors, this translates into lower risk when it comes to enforcing warranty claims in the future, as well as easier access to financing or insurance for PV installations built with modules from this manufacturer. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DT-M-0125-G-EN-A-Datasheet_Vertex-S_NED9R28_2025_A-5e1ea788131f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, lighter, +1.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, lighter, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, lighter, +1.5 pp | | [Trina Solar TSM-DE09R.05-405](https://comparepv.com/panel/trina-solar-tsm-de09r-05-405) | 405 W | -55 W, lighter, -2.7 pp | | [Trina Solar TSM-DE09R.05-410](https://comparepv.com/panel/trina-solar-tsm-de09r-05-410) | 410 W | Hotter, lighter, -2.5 pp | | [Trina Solar TSM-DE09R-415](https://comparepv.com/panel/trina-solar-tsm-de09r-415) | 415 W | Hotter, lighter, -2.2 pp | | [Trina Solar TSM-DE09R.08-420](https://comparepv.com/panel/trina-solar-tsm-de09r-08-420) | 420 W | Hotter, lighter, -2.0 pp | --- Source: https://comparepv.com/panel/trina-solar-tsm-460ned9r-28 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.
