Sydney-based startup SunDrive has given itself an early Christmas present in the form of the fabrication of its first full-sized panel. This panel marks the most recent milestone on the road to commercialization for SunDrive, which set a new world record for commercial-sized silicon solar cell efficiency in September.

Sydney-based solar startup SunDrive, which created the most efficient commercial-sized silicon solar cell in the world in September, has taken to social media to announce its latest feat – the successful fabrication of its first full-size solar panel.
From a garage in Sydney’s south, SunDrive’s chief executive started the company with former flatmate David Hu in 2015 based on a solution developed while completing his PhD at the University of New South Wales (UNSW), adding another chapter to UNSW’s storied solar history.
The solution, reached by hundreds of experiments in trial and error, amounts to a major shakeup of the solar industry’s Chinese cell manufacturing supremacy and replaces traditional and expensive silver use in solar cells with the much more abundant and much cheaper copper. Copper is not as conductive as silver, nor as adhesive to the solar cell, but Allen’s solution rectifies this disparity as evidenced by its 25.54 world efficiency record confirmed by the German Institute for Solar Energy Research (ISFH).
This week’s announcement that SunDrive has successfully fabricated its first full-size panel is another major milestone on the company’s journey from photovoltaic breakthrough to commercial success.
“From our process engineers interconnecting every cell to our build team designing the tools to make all this possible, everyone has put in immense effort to making this a reality,” the company said in a post on LinkedIn . “We are now gearing up to fully automate our technology as we continue to grow our world class team.”
The big “If” of SunDrive has always been whether it can mass produce its technology. If so, the Aussie startup could usher in the next great solar panel cost reduction while also lessening the industry’s dependence on silver, a precious metal of rapidly increasing price .
Silver is central to today’s solar panels . It is estimated solar panel manufacturing accounts for approximately 20% of the world’s annual consumption, a figure which is only going to increase thanks to the next generation of high-efficiency cells which can require up to three times more silver than previous generations.
Allen has previously said SunDrive’s aim is to produce the cells locally, optimistic that they can compete with large solar manufacturers in Asia while protecting their intellectual property.
“The industry today is at a point where the land and labor costs are becoming less and less significant in the total cost of manufacturing … obviously it does mean that we need to at least match that similar level of automation and throughput, but we do see opportunity to do it in Australia,” he said.
On top of more than $2 million in grants from the Australian Renewable Energy Agency (ARENA), SunDrive has already attracted high-profile investors, including Australian billionaire Mike Cannon-Brookes’s Grok Ventures.

Great to hear that PV panels are now going to be manufactured in Australia. I hope they are successful. I would love to see home battery made here as well. Can’t afford an Ev at the moment but would love to be able to get one.
