The Trina Vertex N-Type i-TOPCon 720W Bifacial Dual Glass Solar Panel is a high-performance solar module designed for maximum energy generation and long-term reliability. Featuring advanced N-Type i-TOPCon technology, the panel delivers a powerful 720W output with module efficiency of up to 23.2%.
Its bifacial dual-glass construction allows the module to generate electricity from both the front and rear sides. With 80 ± 5% bifaciality, the panel can achieve additional rear-side energy generation depending on the installation environment and ground albedo.
The module incorporates half-cut cell technology and non-destructive cutting technology to reduce hot-spot risks and minimize micro-cracks. Its low temperature coefficient of -0.29%/°C supports better energy performance in hot operating conditions, while its certified resistance against salt, ammonia, sand, PID, LID, and LeTID makes it suitable for demanding environments.
The Trina 720W features 2.0mm front and back glass, an IP68-rated junction box, anodized aluminium alloy frame, and a maximum system voltage of 1500V DC. With a 12-year product warranty and 30-year power guarantee, it is an excellent choice for commercial, industrial, utility-scale, and large-scale solar installations.
