Vertex N
Vertex N is Trina Solar's large-format n-type module family for commercial, industrial and utility systems. Current European pages cover several cell formats and constructions.
Specifications
| Specification | Value |
|---|---|
| Rated power (W) | 605 to 630 for the documented 2025 NEG19RC.20 schedule; the current family page shows other forms at higher ratings |
| Cell type | n-type monocrystalline i-TOPCon; G3 uses the later i-TOPCon Ultra platform |
| Module efficiency (%) | 22.4 to 23.3 in the documented NEG19RC.20 schedule |
| Dimensions (mm) | 2382 x 1134 x 30 for the documented NEG19RC.20 schedule |
| Power temperature coefficient (%/°C) | -0.29 |
| First-year degradation (%) | 1 for the documented NEG19RC.20 schedule |
| Annual degradation (%) | 0.4 after year one for the documented NEG19RC.20 schedule |
| Product warranty (years) | 12 for the documented NEG19RC.20 schedule |
| Performance warranty (years) | 30 for the documented NEG19RC.20 schedule |
| Performance-warranty end value (%) | 87.4 at year 30 for the documented NEG19RC.20 schedule |
| Bifacial | Yes |
| Sub-ranges | current European examples include NEG21C.20, NED19RC.20 and NEG19RC.20, with separately coded G3 products announced in 2026 |
| Site scale | commercial, industrial and utility |
| Cell layout | 132 half-cells in the documented NEG19RC.20 schedule |
| Weight (kg) | 33 |
| Glass construction | 2.0 mm front and 2.0 mm rear glass in the documented NEG19RC.20 schedule |
| MCS listing | current TSM-575NEG19RC.20 to TSM-630NEG19RC.20 entries existed at 23 July 2026 |
Vertex N is a family of large n-type modules rather than one domestic-roof panel. Current European examples include NEG21C.20, NED19RC.20 and NEG19RC.20, alongside separately coded G3 products.
Representative NEG19RC.20 schedule
The 2025 NEG19RC.20 family has six classes from 605 W to 630 W. It uses a 132-half-cell, double-glass bifacial construction in a module more than 2.3 m long. Those dimensions and electrical values should not be transferred to the other Vertex N codes.
The front-side nameplate rating is measured under standard test conditions. Rear-irradiance examples use separate test conditions, so bifacial contribution is not a fixed addition to the nameplate wattage.
Current family and UK record
Trina’s current European Vertex N page also shows larger and reinforced formats. In June 2026 the company described G3 products with output up to 760 W and availability planned for the second half of 2026. Those ...Q products are a new generation, not revised ratings for NEG19RC.20.
At 23 July 2026, the MCS Product Directory held current NEG19RC.20 entries from 575 W to 630 W. The 2025 NEG19RC.20 manufacturer schedule starts at 605 W, so the lower MCS rows remain certification records without being imported into the structured technical range.
The representative NEG19RC.20 range has 12-year product and 30-year power terms, with 1% first-year degradation, 0.4% annual degradation after year one and 87.4% output at year 30. Other Vertex N codes have their own warranty schedules because the family name does not establish common product cover.
