Australian Solar Startup Prints Panels for 4B Roofs

Millions of industrial rooftops around the world sit empty because they can't support the weight of traditional solar panels, but an Australian startup just got funding to change that.

Kardinia Energy scored $1.5 million from the Australian government to scale up its revolutionary printed solar technology. The Newcastle-based company creates flexible solar panels using the same reel-to-reel printing process that makes newspapers, except on recyclable plastic instead of paper.

The panels weigh less than 0.3 kilograms per square metre. That's lighter than a laptop sitting on your desk, compared to traditional solar panels that can weigh 20 times more.

Kardinia already made waves in 2025 when Coldplay used their mobile solar panels to power a stadium concert. Now they're moving from university proof-of-concept to actual pilot-scale manufacturing.

The company estimates over 4 billion square metres of industrial roof space globally sits unused because those roofs can't bear heavy loads. In Australia alone, that represents 2.4 gigawatts of potential clean energy going untapped.

The government funding will help Kardinia boost production speed and panel efficiency while testing early versions with real customers. Their target manufacturing cost sits below $10 per square metre, making these panels dramatically cheaper than conventional options.

The Ripple Effect

This isn't just about putting solar on a few more roofs. Kardinia's technology opens up an entirely new category of spaces for renewable energy generation.

Warehouses, factories, shopping centres, and older buildings that were off-limits for solar can now join the clean energy revolution. Every square metre of previously unusable roof space becomes a potential power generator.

The recyclable plastic base means these panels can generate clean energy during their lifetime and avoid adding to landfills at the end. Production happens locally in Newcastle, about 150 kilometres north of Sydney, creating Australian manufacturing jobs in renewable technology.

As traditional solar maxes out suitable roof space, innovations like printed panels ensure the renewable energy boom continues accelerating instead of hitting a ceiling.

Four billion square metres of untapped potential is about to get a lot sunnier.
