Trina Solar showcases Vertex S+ 445W n type dual-glass rooftop solutions at Solar Solutions International 2023

Trina Solar Co., Ltd. (“Trina Solar” or the “company”), a leading global PV and smart energy total solution provider, showcases its latest rooftop solutions at this year’s Solar Solutions International trade fair at Expo Greater Amsterdam, The Netherlands. At stand D8 the Trina Solar team welcomes visitors to introduce them to the company’s brand-new n type dual-glass Vertex S+ series for rooftops with up to 445W output power and a 30-year performance warranty. It has been designed for maximum system compatibility, while maintaining similar weight and dimensions as its back sheet peers for easy handling and installation. The new Vertex S+ generation has already started rolling off the production line.

Vertex S+: Rooftop solar for the next generation

Vertex S+ is the first of its kind, and more than just an upgrade of the hugely popular Vertex S range. It brings a robust dual-glass structure, combined with n type cells, to the rooftop market. Vertex S+ features an extended 30-year performance warranty and a 25-year product warranty, as well as an industry-leading low annual degradation. Thus, the product excels in durability, performance, and safety.

Meeting every taste: Optimal bifacial and monofacial options under 2 sqm

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 reaching 22.3% efficiency. 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 (1’762*1’134*30mm) and a black aluminium frame.

A powerful heart: n type cells

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.

Reliable and sustainable: Dual-glass structure

Vertex S+ is the first rooftop module on the market to feature a robust dual-glass structure. As such, dual-glass designs are highly reliable and a perfect protection over decades, extremely resistant to salt spray, acids, and alkalis. Glass is a perfect and symmetrical sealant, thus ensuring zero moisture penetration and minimizing stress on the cells. Also, Vertex dual-glass modules boast the highest possible fire safety. Omitting the back sheet also reduces the use of plastics, further improving the module’s environmental footprint and recycling when it comes to the end of its lifetime.

Handling and compatibility: Designed with the installer in mind

Due to advances in glass processing, 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 back sheet modules. This means that installers can handle the new Vertex S+ on the roof just as they have always handled conventional PV modules.

When it comes to installation, Vertex S+ is highly 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.

Vertex TSM-DE19R for commercial rooftops

Completing the rooftop module range at Solar Solutions is the DE19R Vertex module, most suitable for commercial and industrial rooftop systems. With an output power of up to 580W and 21.5% efficiency, this product has a larger power footprint while it is still well-sized for being handled on flat roofs, such as factories or logistics centers. Its higher module power output results in significant BOS savings for mounting system, cabling, and combiner boxes. This very reliable module forms the backbone of many large rooftop installations across Europe.
