Product Description

Trina Solar Vertex TSM-DE21 is a high-power monocrystalline PERC solar panel designed for utility-scale photovoltaic projects, commercial solar installations, and large-scale renewable energy systems. Featuring advanced 210mm silicon wafer technology, high-density interconnect technology, and multi-busbar (MBB) design, the Vertex DE21 series delivers outstanding power output from 650W to 670W with a maximum module efficiency of 21.6%.

The Trina Solar 670W Vertex module is engineered to reduce the total cost of solar energy generation by increasing power output per module, lowering Balance of System (BOS) costs, reducing installation requirements, and improving overall project return on investment.

With optimized low-voltage design and higher module string power output, TSM-DE21 enables more modules to be connected within a single string, improving system efficiency and reducing photovoltaic system construction costs.

Designed for demanding outdoor environments, the Vertex DE21 solar panel provides excellent reliability against PID, salt mist, ammonia, sand, high temperature, and high humidity conditions. It is an ideal solution for utility-scale solar farms, industrial PV systems, and commercial solar power projects.
