Off-grid energy storage systems are revolutionizing how Australians achieve energy independence, particularly in remote locations where traditional power infrastructure is costly or impractical. From outback stations to coastal eco-homes, these systems are transforming the way we think about energy security and sustainability.
There are enclosures to suit outdoor or indoor installations. Strong steel cabinets with a high quality powder coating finish promote durability and security whilst being well-suited to protected environments like garages, sheds and other enclosed spaces. Like to choose Australian made? Rely on PowerPlus cabinets to protect your next system.
Underground thermal energy storage (UTES) is emerging as a game-changer for larger off-grid applications. By utilizing the earth's natural insulating properties, UTES systems can store heat or cold for extended periods with minimal losses.

These are complete PV solar power systems that can work for a home or business, with just about everything you need to get the system up and running quickly.
A 15kW Solar Kit requires up to 1,200 square feet of space. 15kW or 15 kilowatts is 15,000 watts of DC direct current power. This could produce an estimated 1,000 to 2,500 kilowatt hours (kWh) of alternating current (AC) power per month, assuming at least 5 sun hours per day with the solar array facing South.
At the time of its installation, Adelaide Airport's 1.17MW rooftop solar system was Australia's largest airport solar installation, but that record has since been shattered by larger airports across the country.
The cost of solar panel installation in Australia averages around $1,000 per kW. For a popular 6.6kW system, expect to pay between $5,000 - $8,500 for good components and an installation that will last. Over their lifetime, our analysis shows that rooftop solar panels can produce electricity at close to 4c per kilowatt-hour.
With a commitment to renewable energy, Brisbane Airport Corporation will be adding more rooftop solar panels to our existing solar system. at the International Terminal.
Adelaide Airport has completed the installation more than 3,800 solar panels on its international and domestic terminal rooftops, adding a further 2.2 megawatts of generation capacity and tripling the size of total PV installed.
