According to data from Solar Choice's installer network database, a fully installed 20kW system will cost roughly $15,000 – $22,000 as of August 2024. These figures include the up-front 'discount'/incentive available under the federal government's Renewable Energy Target for systems under 100kW in output capacity, as well as GST.
A north-facing roof is still the gold standard in Australia, but east-west arrays can also do well, especially if your energy usage stretches across the day. As of 2025, the base price for a 20KW solar system usually starts at around A$10,299, but that's just for the hardware.
At the July 2025 commercial price of ≈ $0.90 /W a 22 kW system costs about $1 800 more than 20 kW. After extra STCs (≈ 60 certificates worth ~$500 – $600) the true gap narrows to ≈ $1 200 —roughly 8 % extra-spend for 10 % extra capacity. What are the other solar system sizes mostly used in Australia?
As technology continues to improve, the average solar panel efficiency (size vs. output) continues to improve. Depending on the solar panels, a 20kW solar system typically uses between 43 - 52 individual solar panels and requires a roof size of around 73m 2 – 88m 2 to accommodate them.
