Trina Solar Launches Vertex S+ Dual-Glass Modules for Rooftops

Global PV and smart energy total solution provider Trina Solar has launched a new generation of rooftop modules at the Genera trade fair in Madrid, Spain. The new Vertex S+ n type dual-glass product line in unveiled with output power reaching 445W, the highest in an area of less than 2 square meters.

Trina said that these modules, featuring the power warranty up to 30 years, have already entered mass production.

Trina says that new solar modules for rooftops offers maximum power output from limited space, trouble-free installation and operations over decades; and good looks on the roof.

Bifacial and Monofacial Options Under 2 sq Meters

Trina held that 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.

A Powerful Heart: n-Type Cells

As all Trina Solar modules, Vertex S+ is based on the 210mm Vertex technology platform. Due 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 also ramped up its n type factory securing supply of n-type i-TOPCon cells for modules of all sizes.

Dual-Glass Structure

Trina also called Vertex S+ as the first rooftop module to feature a dual-glass structure, replacing the plastic backsheet with a second layer of glass. This makes the module structure resistant to salt spray, acids, and alkalis. Also, Vertex dual-glass modules boast the highest possible fire safety.

Trina Solar was able to use two layers of ultra-thin glass with just 1.6mm thickness, leading to a low weight of 21.1kg, which is comparable to backsheet modules. This means that installers can handle the new Vertex S+ on the roof just as they have always handled conventional PV modules.

For installations, Vertex S+ is compatible with other BOS components. It offers a variety of mounting methods including short side and long side clamping, crossed beam, shared rail and slide-in mounting. Thanks to its short circuit current of 10.7A, it is also compatible with more than 99% of mainstream inverters in the market, as verified by a comprehensive compatibility analysis.

Last month, Trina rolled out 210 mm n-type i-TOPCon cells off the production line in its 8 GW capacity factory in Suqian, Jiangsu province of China.
