Onyx Solar has partnered with Australian building products supplier Metz to provide a bespoke 247 kWp BPIV solution for the Atlassian Central tower currently being built adjacent to Sydney’s Central Station.
The 182 meter Atlassian tower combines a hybrid mass timber structure surrounded by a steel exoskeleton supporting a PV glazed facade featuring 1,794 crystalline silicon solar modules.
“Thanks to Onyx PV facade, the tower turns its skin into a power source,” Onyx said, adding that the solar panels are part of a self-shading system that reduces direct heat gain, enhances energy efficiency, and significantly lowers the building’s carbon footprint. “Our PV glass, apart from the capacity to be fully adapted to architectural design, can be customised to block the heat that enters the building and to provide the best insulation, thus reducing the use of air conditioning and heating,” the company said.
The company said the design allows natural light to enter, reducing the need for artificial lighting and lowering energy consumption. It added that combining these passive benefits with on-site energy generation in a single building material makes its PV glass unique, enabling buildings to produce electricity without compromising comfort or aesthetics.
It added that the BIPV system designed for the Atlassian project features solar panels measuring 2,468 nn x 351 mm and 2,323 mm x 341 mm. The glass configuration is a 4T+4T mm thickness. Each PV glass piece includes 28 mono-crystalline cells. Each unit has a peak power of 138 Wp, with the system boasting a total nominal power of 247 kWp.
Onyx said its solar glass allows buildings to generate the energy they need, turning them into “vertical generators.”
“Our technology does not sacrifice design: the PV glass can be coloured and semi-transparent, it filters solar radiation, and provides thermal and acoustic insulation,” the company said, adding it can be installed in building facades, skylights, and walkable floors. “We also offer tailored solutions for existing buildings, including PV glass installations for rooftops.”
The 39-storey Atlassian Central tower is expected to open in 2027. Atlassian has committed to a 100% renewable energy operation on completion.
