Trina Solar has rolled out a new generation of rooftop modules: the Vertex S+ n-type dual-glass product line with output power that reaches 445 W. Available in monofacial with a white rear encapsulant and a transparent bifacial, this shift to n-type i-TOPCon cells means about 10% extra energy over 30 years plus a 50% lower initial degradation and 11% lower annual power attenuation.
