Chinese PV module manufacturer Trinasolar will unveil a full-black dual-glass TOPCon solar module for residential and commercial and industrial (C&I) applications at the All Energy Australia conference starting in Melbourne on Wednesday.

Edison Zhou, Trina’s head of operations in Australia, New Zealand and Pacific Islands, said the “Australian-exclusive” Vertex S+ G3 Full Black solar module marks the return of the company’s all-black offering, combining its distinctive design with next-generation TOPCon 3.0 technology.

“Black is back with more power, greater efficiency and next-generation solar technology,” he said. “The Vertex S+ G3 combines the premium all-black design customers want with the performance and reliability they expect from Trinasolar.”

The Vertex S+ G3 is built on Trinasolar’s n-type i-TOPCon Ultra technology, and features “zero-gap” stacked welding and “zero-string bar” technologies.

Trinasolar is offering five variants, with power output ranging from 490 W to 510 W and power conversion efficiencies between 23.5% and 24.4%. Open-circuit voltage ranges from 39.4 V to 40.0 V, while short-circuit current is between 15.91 A and 15.97 A.

The panels feature 1.6 mm glass front and back in a black anodised aluminium frame. They measure 1,842 mm x 1,134 mm x 30 mm and weigh 21.95 kg.

They can be deployed in systems with a maximum voltage of 1,500 V and feature IP68-rated junction boxes. The temperature coefficient is -0.26% per C, with an operating temperature range of -40 C to 70 C.

The modules are backed by a 25-year product warranty and a 30-year performance warranty. 5% of nominal power.
