Vertex S+ NEG9R.25
TSM-NEG9R.25 is the full-black, monofacial member of Trina Solar's Vertex S+ rooftop range. The 2025 manufacturer schedule covers 430 W to 455 W classes.

| MCS listing | current 375–400 W and 440–465 W code groups existed at 23 July 2026; these extend beyond the 430–455 W manufacturer schedule |
TSM-NEG9R.25 is the full-black Vertex S+ module intended for rooftop use. It is a monofacial product despite using glass on both sides: the rear treatment is not the transparent construction used by the bifacial Clear Black form.
Manufacturer schedule
The 2025 English datasheet contains six classes from 430 W to 455 W. Each has the same enclosure, weight and cell count. Their maximum-power voltage rises from 43.2 V to 45.0 V and maximum-power current from 9.96 A to 10.11 A, so the wattage remains part of string-design records.
The listed connector is also order-dependent. A family name or product photograph does not establish whether an installed module carries a TS4, TS4 Plus or MC4 EVO2 connector.
The later Vertex S+ G3 Full Black uses the similar-looking NEG9RP.25Z code. Its cell platform and published performance figures are different, so the added P and Z are material identification characters rather than optional catalogue notation.
MCS range mismatch
On 23 July 2026, the MCS Product Directory contained two current groups: 375 W to 400 W entries certified from April 2024 and 440 W to 465 W entries certified from March 2026. The current manufacturer datasheet covers 430 W to 455 W.
That difference is preserved rather than blended into a single rating range. An MCS entry confirms the lifecycle of the exact listed code, while the module label and matching manufacturer datasheet provide the electrical and mechanical specification. A 465 W directory row is not evidence that the 2025 455 W datasheet extends to 465 W.
