Rooftop solar panels and hot water systems now generate more than five gigawatt of power in Australia.

That’s nearly twice the size of the nation’s largest power station.

But the panels themselves are still fairly bulky—hefty silicon and aluminium rectangles that have to be installed on brackets on your roof.

Researchers at Newcastle University in New South Wales have spent the past 15 years developing a new technology that make panels thinner and easier to install by printing them.

So far, they’ve successfully printed 100 metres of solar cells onto thin plastic sheets using standard printers.

They claim the technology could provide vast amounts of solar energy at very low cost.
