Australian airports have the potential to generate sufficient solar vitality to power a regional metropolis, in accordance to a brand new RMIT University examine.
The examine discovered that if large-scale rooftop solar programs have been put in at Australia’s government-owned airports, they may produce sufficient electrical energy to power 136,000 properties.
Previous research have deemed airports as nice solar mills, however the RMIT analysis goes additional by exactly modelling using large-scale programs.
The researchers in contrast electrical energy generated by residential solar panels in a regional metropolis with the potential inexperienced vitality manufacturing of 21 leased federal airports. They discovered that if large-scale solar panels have been put in on the airports they’d generate 10 instances extra electrical energy than the town’s 17,000 residential panels, whereas offsetting 151.6 kilotons of greenhouse gases yearly.
Researcher Dr Chayn Sun stated the evaluation confirmed the worth of focusing renewable vitality efforts on massive centralised rooftop solar programs.
“We can’t rely on small residential solar panels to get us to a zero-emission economy, but installing large panels at locations like airports would get us a lot closer,” she stated.
“We hope our results will help guide energy policy, while informing future research in solar deployment for large buildings. There’s so much potential to facilitate national economic development while contributing towards greenhouse gas emission reduction targets.”
Dr Sun, a geospatial scientist in RMIT’s School of Science, stated airports are perfect for solar panels however aren’t presently getting used to their full potential — many Australian airports are with out enough solar programs.
“Airports get good sun exposure because they’re not shaded by tall buildings or trees, making them a perfect spot to harness the sun’s energy,” she stated.
“Australia is facing an energy crisis, yet our solar energy resources — such as airport rooftops — are being wasted. Harnessing this power source would avoid 63 kilotons of coal being burned in Australia each year, an important step towards a zero-carbon future.”

To conduct the analysis, printed in The Journal of Building Engineering, geospatial researchers estimated the solar electrical energy generated from 17,000 residential solar panels in Bendigo, Victoria, over one 12 months.
Lead creator Athenee Teofilo, a Master of Geospatial Science scholar, then mapped the buildings in each leased federal airport — excluding unsuitable buildings like dome and blister-type hangars — and recognized 2.61 km2 of usable rooftop house.
Researchers decided the optimum tilt angle for the solar arrays for every airport, to maximise effectivity.
Perth Airport had most energy-generating potential — putting solar panels there might produce virtually twice the solar output of Bendigo, equal to the mixed manufacturing from Adelaide, Sydney, Moorabbin and Townsville airports.
Even Melbourne Airport alone would outperform Bendigo’s annual solar electrical energy manufacturing by virtually 12 GWh a 12 months.
Airport buildings much less suited to solar panels, like these at Alice Springs and Tennant Creek, might nonetheless be helpful for ground-mounted solar programs, the examine discovered.
Dr Sun stated the analysis underlined the need for vitality insurance policies to embrace a plan for putting in solar panels at airports.
“Based on our solar radiation analysis, we know airports with decent solar systems could not only be self-sufficient but would generate enough electricity to send the excess back into the grid,” she stated. “We mapped airports owned by the federal authorities, however Australia has greater than 150 privately owned airfields, which might even have panels put in.
“Australia receives so much solar radiation — every airport in the country would benefit from having the right type of solar panels installed.”
Dr Sun stated reflections from the panels wouldn’t be an issue, as fashionable solar arrays take up somewhat than mirror daylight.
The findings may very well be prolonged to assess the solar potential of different websites, comparable to massive business buildings, warehouses or distribution centres.
