Trina Solar Vertex N bifacial dual-glass module with N-type TOPCon cells, for high-output commercial and utility arrays.
The Vertex N TSM-NEG19RC.20 is a bifacial, dual-glass module from Trina Solar using N-type TOPCon cells. Bifacial modules can also generate electricity from light reflected onto their rear side, which makes them particularly suitable for elevated structures and ground-mounted systems.
Trina has published several datasheet versions for this model with different power ranges. The values below are taken from Trina's 2024 global datasheet; earlier regional versions list lower power ranges.

It depends on how much electricity you use, when you use it, and the space available. We review your electricity bills and loads during a site survey and size the system accordingly.
On-grid systems work with the utility supply and need no batteries. Off-grid systems run independently with batteries. Hybrid systems combine both, so they can keep essential loads running during power cuts. We recommend the right type after understanding your needs.
Yes. Panels still produce electricity on cloudy days, although output is lower than in full sunshine. Systems are sized with seasonal variation in mind.
Mainly regular cleaning of the panels to remove dust, and periodic inspection of connections, protection devices, inverters and batteries. We offer maintenance and inspection services.
