Show series description

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.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
