Trina Solar Vertex N TSM-NE21 695-725W modules are designed for maximum energy production on large-scale projects, where rapid return and reliable operation over the long term are crucial. The application of N-type cells in TOPCon technology translates to more stable performance and lower power degradation over time, effectively improving project profitability without the need for "overprovisioning."

The key advantage is the bifacial dual-glass construction - the module can also utilize reflected light from the ground, increasing yield in PV farms and ground-mounted installations. Furthermore, high power output with a low-voltage concept facilitates cost optimization in the Balance of System (BOS): fewer modules, fewer components, faster installation, and simpler on-site logistics.

This solution is tailored for investors, EPC contractors, and developers of solar farms who aim to lower the levelized cost of energy (LCOE) and build installations resilient to operational risks. Against competitors, this series stands out with its longer warranty period and emphasis on reliability, which is significant for financing and project bankability.

Common questions

6 answered
How does TOPCon technology in Trina Vertex N TSM-NE21 panels differ from standard PERC cells?
N-type TOPCon cells have lower power degradation over time and perform better at higher temperatures than conventional P-type PERC cells. In practice, this means higher energy yield over a 25-year lifespan and reduced risk of performance loss, which matters most on large solar farms where every percentage point of efficiency counts.
Are the Vertex N TSM-NE21 panels bifacial?
Yes, the modules use a dual-glass bifacial construction, so the rear side also generates power from light reflected off the ground surface. With a bifaciality factor of around 80%, this translates into a real yield boost, especially on ground-mounted installations over light-colored surfaces, gravel, or white membrane, where the albedo effect is significant.
What warranty does Trina Solar offer on the Vertex N TSM-NE21 695-725W series?
The manufacturer provides a 12-year product warranty and a 25-year power output warranty, guaranteeing 89.4% of original power retention after that period. As a Tier 1 manufacturer, Trina Solar offers stable service support, which is an important factor when financiers assess the bankability of a project.
How many Vertex N 725W panels are needed to build a 1 MW PV plant?
With a maximum unit power of 725 Wp, roughly 1,380 modules are needed to reach 1 MWp, fewer than with lower-power panels. This reduces the number of mounting structures, connectors, and installation time, directly lowering BOS costs and speeding up project completion.
Are Vertex N TSM-NE21 panels suitable for residential sloped roofs?
This series is designed mainly for large commercial and ground-mounted installations rather than typical residential sloped roofs. The module's large dimensions and high unit power make it better suited to large, flat, or gently sloped areas where maximizing power per square meter is the priority.
Is the Trina Vertex N TSM-NE21 695-725W series still available for purchase?
Yes, the series remains part of the manufacturer's current lineup and has not been discontinued. Trina Solar continues to develop it alongside newer Vertex N variants, so these modules are still supplied to distributors and used in new farm and commercial installation projects.
