Trina Solar has launched a new Vertex S+ rooftop solar module series using n-type i-TOPCon cells. The company is offering two versions of the panel – a monofacial module with a white backsheet and a bifacial module with a transparent backsheet. The bifacial module has a front-side power of 435 Wp at 21.8 per cent efficiency while the monofacial module has a maximum power of 445 Wp and reaches 22.3 per cent efficiency. In comparison to its p-type competitors, the module may produce roughly 10 per cent more energy over 30 years by using n-type i-TOPCon cells.
According to Trina Solar, n-type cells have a 50 per cent lower initial deterioration and an 11 per cent lower annual power attenuation. Hence, the product will be more reliable and have better energy yield over the duration of the module’s life. Both models have a surface area of just under 2 square metres and a 21.1 kg black aluminium frame. The products support a number of mounting methods, including slide-in mounting, shared rail, crossed beam, and short- and long-side clamping.
