The key feature is the **dual glass construction** - instead of a traditional backsheet, glass is used on both sides, improving resistance to moisture, aggressive environments (e.g., coastal areas) and long-term thermal stress. Combined with **n-type i-TOPCon cells**, the module offers high efficiency even under low-light conditions and slower degradation, translating to a more predictable yield over the installation’s lifecycle. Vertex S+ is also practical for installation teams - its format optimized for roofs and popular mounting systems simplifies on-site logistics, while connection solutions support compatibility with modern inverters and optimizers. For investors, this means **greater long-term reliability** and reduced risk of performance declines. It’s an excellent choice for homes, small businesses, and projects where **aesthetics (including the full black version)** and high craftsmanship quality are key. ## Notable figures - Efficiency of 21.1% is 0.8pp below the \*\*N-type 400-450W\*\* median (21.9%) - 211.3 W/m² power density is 7.1 W/m² below \*\*N-type 400-450W\*\* median (218.4 W/m²) - requires larger installation area - At -0.30%/°C, hot weather performance is typical for \*\*N-type 400-450W\*\* panels - #9365 for efficiency, #6152 for temperature performance out of 14129 panels ## Questions ### How does the dual glass construction of the Trina Vertex S+ differ from a standard backsheet panel? In a standard module, the rear layer is a polymer backsheet, while the Vertex S+ Dual Glass uses tempered glass on both sides. This construction offers better protection against moisture, microcracks, and PID degradation, keeping performance stable in demanding conditions such as coastal areas or wide temperature swings. It also improves fire resistance and makes the glass easier to recycle at end of life. ### What warranty comes with the Trina Vertex S+ 425W panels, and what does it cover? The manufacturer provides a 25-year product warranty against material and workmanship defects and a 30-year linear power output warranty. Thanks to the n-type cells, first-year power degradation is capped at 1%, dropping to around 0.4% per year afterward, so the module should still deliver strong output relative to its nominal power after three decades of operation. ### Are Trina Vertex S+ 425W panels suitable for a sloped residential roof? Yes, the 1762×1134 mm format and roughly 21 kg weight are typical for residential installations and fit well with common mounting systems used on sloped roofs. The half-cut cell design also improves shading tolerance, which matters on roofs with chimneys, dormers, or antennas where shadows fall on only part of the array. ### What is n-type i-TOPCon technology in the Vertex S+ series, and is it worth the investment? i-TOPCon is an n-type cell technology with an extra passivation layer that reduces electron recombination losses and pushes module efficiency above 21%. In practice this means better performance under weak or diffuse light and slower degradation compared to older p-type PERC cells. For an investor, this translates into higher lifetime energy yield despite a somewhat higher upfront cost. ### Are Trina Vertex S+ panels bifacial and able to generate power from both sides? No, this specific Vertex S+ Dual Glass 425W version is a monofacial module despite the glass rear layer. Glass was used instead of a backsheet for durability and environmental resistance, not to capture rear-side light. Buyers looking for rear-side energy gain should check Trina Solar's dedicated bifacial product lines instead. ### Is Trina Solar a tier 1 manufacturer, and can it be trusted for a 25-30 year investment? Yes, Trina Solar is one of the world's largest PV module manufacturers, headquartered in China with tier 1 status, reflecting solid financial standing and decades of production experience. This matters for long warranty periods like 25 years on the product and 30 years on power output, since it increases the likelihood the company will remain operational to honor warranty claims throughout that time. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/36829073764d48c10c6b4e-9cb704655207.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, cooler, +2.5 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, lighter, +2.5 pp | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +2.4 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, cooler, +2.4 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +2.4 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, heavier, +2.2 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +45 W, cooler, +2.2 pp | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, +2.2 pp, -5 yr warranty | | [Trina Solar TSM-400NEG9.28](https://comparepv.com/panel/trina-solar-tsm-400neg9-28) | 400 W | -10 W, -0.5 pp | | [Trina Solar TSM-405NEG9.28](https://comparepv.com/panel/trina-solar-tsm-405neg9-28) | 405 W | -0.2 pp | | [Trina Solar TSM-415NEG9.28](https://comparepv.com/panel/trina-solar-tsm-415neg9-28) | 415 W | +0.3 pp | | [Trina Solar TSM-420NEG9.28](https://comparepv.com/panel/trina-solar-tsm-420neg9-28) | 420 W | +10 W, +0.6 pp | | [Trina Solar TSM-425NEG9.28](https://comparepv.com/panel/trina-solar-tsm-425neg9-28) | 425 W | +15 W, +0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +85 W, cooler, +3.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +95 W, cooler, +3.6 pp | --- Source: https://comparepv.com/panel/trina-solar-tsm-410neg9-28 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
