South Australia has the highest electricity prices in the country, which means solar savings in Adelaide are among the best nationally. The state also has Australia's highest rooftop solar penetration — over 40% of homes have panels. Strong sun hours and the SA Home Battery Scheme make Adelaide one of the best places in Australia to invest in solar and battery storage.
💡 Local Tip
SA's high solar penetration means export limits are increasingly common. A battery is particularly valuable in Adelaide because it lets you use your solar instead of exporting at low feed-in rates (currently ~4c/kWh).

Get My Solar Score ☀Adelaide Feed-in Tariffs
The current feed-in tariff in SA is approximately 4.0c/kWh for excess solar exported to the grid. With feed-in rates this low, maximising self-consumption (using solar during the day) is more valuable than exporting. A battery can help shift solar to evening use.
At current rates, a 6.6kW system in Adelaide exporting around 60–70% of generation would earn approximately $313/year in feed-in credits. The real savings come from self-consumption — every kWh you use directly saves 38c versus the 4.0c you'd earn exporting it.
