Across Australia, a quality 20 kW array installed on a standard iron or tiled roof with no major upgrades falls between $15 000 and $22 000, including GST and the federal STC incentive. That headline range converts to roughly $750 – $1 100 per installed kilowatt. How many panels are in a 20kw solar system? How much area is required?
With a daily power output north of 70kWh each day depending on your location and the position of your property, a 20kW solar system has the potential to generate enough power to pay for the upfront cost and become an ROI positive investment for most businesses in a few short years. How much does a 20kW solar system cost in Australia?
In 2016, a 20 kW array routinely cost ~ $32 000 (≈ $1.60 /W), matching the $1.62 /W national average recorded that December. By mid-2025, bulk pricing sits near $0.90 /W, halving nominal system cost to ~ $18 000. The drop stems from cheaper modules, a stronger STC market, and intense installer competition.
With a well-installed 20kW commercial solar system, you can save up to $10,000 every year. Since it generates so much power daily, you can save money by consuming the generated power, storing it for later use, and even the feed-in tariff.
