Trina Solar has released a new generation of rooftop solar modules: the Vertex S+ n-type double glass product line with an output power of 445W.
Trina says the Vertex S+ is available in two specifications. The single face NEG9R.28 features white back encapsulation for maximum output power, up to 445 Wp and 22.3% efficiency. In contrast, the transparent NEG9RC.27 is a bifacial module with a front-side power of 435 Wp and an efficiency of 21.8%. Both types have a surface area of just under two square meters and a black aluminum frame.
Like all Trina Solar modules, the Vertex S+ is based on the 210 mm Vertex technology platform. However, thanks to the switch to n-type i-TOPCon cells, the module can generate about 10% more energy over 30 years compared to p-type counterparts. In addition, n-type cells have 50% lower initial breakdown and 11% lower annual power attenuation. Both factors combined—higher power and lower degradation—result in significantly better energy yield over the module’s lifetime and improved reliability, the company says.
Trina notes that the Vertex S+ is the first roof module on the market with a robust double glass construction that replaces the plastic backing layer with a second layer of glass. The double glass structure makes the module structure very resistant to salt spray, acids and alkalis. In addition, the glass is a perfect and symmetrical seal, which ensures the penetration of moisture and minimizes the strain on the cells.
The Vertex S+ is highly compatible with other BOS components and offers a variety of mounting methods, including short side and long side mounting, crossbar, split rail and slide mounting. With its 10.7A short-circuit current, it is also compatible with more than 99% of mainstream inverters on the market.
Modules that have already entered mass production have a power guarantee of up to 30 years.
