Trina Solar has launched upgraded Vertex N 720W series modules, alongside Vertex N 625W and Vertex S+ 455W models at the Tokyo PV Expo. The laser-induced firing increased the module efficiency by 0.3%, and now the Vertex N 720W modules boast 23.2% efficiency, while the N 625W and S+ 455W models reach 23.1% and up to 22.8% efficiency, respectively. The Vertex N 720W series modules designed for ground-mounted power stations comes with low-voltage and high bifaciality. The Vertex N 625W modules are suitablefor utility-scale or C&I solar applications, while the Vertex S+ 455W modules serve residential solar applications. All the above modules have Trina Solar designated 210mm dimension.
