Trina Solar Launches Vertex S+ 445W N Type Dual-Glass Modules for Rooftops

Trina Solar launched a new generation of rooftop modules at the Genera trade fair in Madrid, Spain: the Vertex S+ n type dual-glass product line with output power reaching 445W, the highest in an area of less than 2 square meters.

These modules, combining several cutting-edge technologies, featuring the power warranty up to 30 years, have already entered mass production.

When it comes to selecting solar modules for rooftops, installers and their customers are looking for three things: Maximum power output from limited space; trouble-free installation and operations over decades; and good looks on the roof. This is precisely where Trina Solar's new Vertex S+ series comes into play.

Rooftops and individual preferences may differ slightly between application scenarios. Therefore, Vertex S+ is available in two specifications. The monofacial NEG9R.28 comes with a white rear encapsulant for maximum output power boasting up to 445Wp and efficiency reaching 22.3%.

In contrast, the transparent NEG9RC.27 is the preferred option for high-end aesthetic applications, for example on residential rooftops where the array would all but disappear optically.

This bifacial module features a front side power of 435Wp, at 21.8% efficiency. Both types feature a surface area of just under 2 square meters and a black aluminum frame.

As all Trina Solar modules, Vertex S+ is based on the 210mm Vertex technology platform. However, thanks to the shift to n type i-TOPCon cells, the module can generate approximately 10% extra energy over 30 years, compared to its p type peers.

Moreover, n type cells have a 50% lower initial degradation and an 11% lower annual power attenuation. Both factors combined – higher power and lower degradation – result in a substantially boosted energy yield over the module's lifetime, and improved reliability.

Trina Solar has ramped up its brand new, vertically integrated n type factory securing supply of n-type i-TOPCon cells for modules of all sizes.

This product creates added value both for installers and end customers in dimensions of energy yield, durability, and sustainability – in short, future-proof solar power.
