What Is Trina Vertex N TSM-NEG19RC.20
Trina Vertex N series adopts n‑type cell technology, bringing lower temperature coefficient, better low‑light performance and higher bifacial gain compared with traditional p‑type modules. The TSM-NEG19RC.20 is designed specifically for utility and commercial projects where investors chase maximum power output over decades.
Unlike single‑glass modules, dual‑glass construction removes the backsheet completely, greatly improving resistance against humidity, ammonia, salt mist and potential induced degradation (PID).

Mechanical Data: Dimensions, Weight & Packaging
Physical size and packaging are critical for logistics, mounting structure design and container loading planning.
| Mechanical Item | Value |
|---|---|
| Length × Width × Thickness | 2382 × 1134 × 30 mm |
| Module Weight | 33.0 kg |
| Front / Back Glass | 2.0 mm |
| Quantity per Pallet | 36 Pcs |
| Quantity per 40HQ Container | 720 Pcs |
Dual‑glass panels are heavier than conventional backsheet modules, so mounting brackets and transportation need to be calculated accordingly.
STC Electrical Parameters & System Design Notes
All values below are measured under standard test conditions (STC): irradiance 1000 W/m², cell temperature 25°C, AM 1.5 spectrum.
| Electrical Parameter | Value |
|---|---|
| Open Circuit Voltage (Voc) | 41.43 V |
| Maximum Power Voltage (Vmp) | 39.00 V |
| Short Circuit Current (Isc) | 15.69 A |
| Maximum Power Current (Imp) | 16.74 A |
| NOCT | 43℃ ± 2℃ |
| Pmax Temperature Coefficient | -0.29% /℃ |
Thanks to the excellent temperature coefficient, power loss under high working temperature is much smaller than old generation modules, which brings extra power gain in hot regions.

Suitable Installation Application Scenarios
This 650 W bifacial module is most widely used in three main scenarios.
Commercial Ground‑Mount Solar Farm
Ground‑mount installations can fully take advantage of bifacial power gain from albedo reflection on grass, gravel or white ground. Large power plants prefer high‑watt modules to reduce total mounting structure, cabling and installation labour cost.
1P Solar Tracker System
Single‑axis trackers perfectly match high power n‑type modules. The tracker continuously adjusts the panel angle to follow sunlight throughout the day, combining with bifacial gain to greatly increase annual power generation.
Large Industrial Rooftop
For big flat industrial rooftops with enough load capacity, the Trina 650 W dual‑glass panel is a solid option. Its outstanding anti‑corrosion performance makes it suitable for factories near coastal areas with salt air.

FAQ
What does bifacial mean?
Bifacial solar cells can capture sunlight from both front and back sides of the panel. Reflected light from the ground can be converted into extra electricity to boost total energy production.
Is dual glass better than backsheet?
Dual‑glass modules have much better resistance against humidity, salt mist and PID. The downside is higher weight and higher upfront cost.
Can I use this panel for residential rooftop?
Generally, 650 W large modules are designed for commercial and utility projects. They are too heavy and oversized for most household rooftop systems.
What is NOCT?
NOCT stands for Nominal Operating Cell Temperature. It indicates the real working temperature of solar cells under normal outdoor conditions. Lower NOCT is better.
