Trina 665WP Vertex TSM-DE21 Solar Panel

The Trina 665WP Vertex TSM-DE21 Solar Panel is a high-power monocrystalline solar module designed for superior energy yield and long-term stability. At STC, it delivers 665 Wp with 21.4% module efficiency, operating at Vmp 38.0 V, Imp 17.51 A, Voc 45.9 V, and Isc 18.57 A. Under NOCT conditions, output reaches 504 W, with Vmp 35.4 V, Imp 14.22 A, Voc 43.2 V, and Isc 14.96 A. Built with 132 high-efficiency cells, multi-busbar technology, and Trina’s high-density interconnect design, it reduces resistive losses and enhances real-world performance. The module supports 1500V systems, offers a low power temperature coefficient of –0.34%/°C, and withstands 5400 Pa snow load and 2400 Pa wind load. Backed by a 12-year product warranty and a 25-year performance warranty, the TSM-DE21 665W is ideal for commercial, industrial, and utility-scale solar projects seeking maximum output and long-term reliability.
