The University of Queensland is home to the largest rooftop solar panel system in Australia.
Five thousand solar panels, which have been installed on four buildings at the university's St Lucia campus, are collectively the size of one-and-a-half football fields.
The $7.75 million solar generating system would produce about 5 per cent of the university's peak power demand, which is enough to power 800 households at once.
The 1.22 megawatt solar panel array is almost 25 per cent larger than Australia's second largest flat-panel system – the one megawatt installation at the Adelaide Showgrounds that was built in 2010.
And it is more than double the size of the 500 kilowatt system installed at the Sydney Theatre Company.
Premier Anna Bligh, whose government invested $1.5 million in the project, said it would be a globally significant research facility to provide scientists with real life data on energy management and the impact of solar on the electricity network.
"Information from projects at a commercial scale is vital to improving the performance of solar energy and to encourage its uptake by both the private sector and the public," she said.
Through a partnership with Brisbane company RedFlow, a 200 kilowatt battery will be connected to a 339 kilowatt section of UQ's solar array to allow research into solar power capture techniques during the day and feeding it into the grid at night and other times of peak demand.
