Trina Vertex S Plus TSM-445NEG9RH.25 Solar Panel, 445W, MC4, 35mm Black Frame, Black Backsheet, Dual-Glass, 96 N-Type Half Cell Mono, 30A Fuse, 1500VDC, XXX.XW PTC

The Trina Solar Vertex S+ TSM-445NEG9RH.25 is a premium N-type TOPCon dual-glass solar module built to deliver strong performance, long-term reliability, and a clean, modern look for both residential and commercial rooftop systems. With up to 445W of output and 22.3% efficiency, it offers an excellent balance of power and aesthetics, especially for projects where appearance matters just as much as performance.

What really sets this module apart is its combination of advanced TOPCon cell technology and Trina’s 210R platform. Together, these innovations help improve energy production through lower electrical losses, better light capture, and enhanced overall efficiency. It also performs well in less-than-ideal conditions, maintaining stable output thanks to strong low-light performance and a low temperature coefficient of -0.29%/°C, which helps minimize power loss in hotter climates.

The dual-glass construction adds another layer of value by improving durability and long-term performance. It helps protect the module from microcracks, moisture, UV exposure, and thermal stress, making it a solid choice for harsher environments like coastal or high-humidity regions.

From an installation and reliability standpoint, this module is built to last. It’s resistant to PID, salt, ammonia, sand, and dust, and is designed to handle demanding environmental conditions without compromising performance. The full-black design gives it a sleek, uniform appearance that integrates well with modern rooftops, making it a popular choice for homeowners who want a more refined look.

In addition, Trina Solar’s US-based support teams provide an extra layer of confidence for installers. Their local expertise helps streamline project execution, improve customer satisfaction, and support business growth with dependable service and technical backing.
