The overall array, stretching across 3.6 hectares, will account for 18 per cent of Brisbane Airport Corporation's direct electricity consumption, saving it about $1 million in energy bills annually.
"We are in the enviable position of having thousands of square metres of unimpeded roof space ideal for solar harvesting," BAC's general manager for assets, Krishan Tangri, said.
"It makes financial sense to invest in this readily available supply of renewable energy to save costs and decrease our carbon footprint."
In all, the Brisbane Airport system will comprise 22,000 panels and an $11 million investment. When fully installed it will be capable of generating 9.3 gigawatt hours of energy annually.
The airport project, being installed by Epho in collaboration with Shakra Energy, will be complete by August next year.
It became commercially viable as the cost of solar panels fell, their efficiency increased and as energy prices began to rise.
