Home Solar Power In South Australia

Last Updated: 29th Jul 2026

Solar panels can be seen on the rooftops of homes just about everywhere you look in South Australia — SA’s residents are very switched on to the savings that installing PV can bring.

More than 441,928 systems had been installed across South Australia as at early December 2025 according to Australia’s Clean Energy Regulator, representing more than 2.81 GW of capacity.

Given SA’s population of 1,899,000 (March 2025 – Population.Gov), this breaks down to a very impressive 1.48 kW of small-scale solar installed per capita; blasting past the national average of 1 kW.

Approximately 53.7% of detached/semi detached dwellings in South Australia have had systems installed, making it second in the country for residential PV installation saturation.

SA’s love affair with solar power shows no signs of slowing – and why would it when the costs of large systems are so low now, thanks in part to Australia’s generous solar subsidy that is still available.

While SA has always had high electricity prices, the reason for this isn’t renewable energy – it’s *why* the state has so much renewable energy.

A 6.6kW system installed in Adelaide can generate around 28kWh of clean electricity a day on average over a year. That’s significantly more than the average household uses. Any surplus electricity generated can receive a solar feed in tariff in SA – a payment for electricity that is exported to the mains grid.

Home Batteries Blast Onto The SA Scene

When the federal government introduced its national home battery rebate in 2025, many South Australian solar owners took the opportunity to install residential energy storage at deeply discounted prices. The scheme formally kicked off on July 1, 2025 and by the end of the year, 16,488 new battery systems had been installed and commissioned.

The good news is, while reducing over time, the rebate will continue until the end of 2030.
