SA retailer feed-in rates
Each row is the retailer's best generally available flat rate in SA: open to anyone switching, with no battery, VPP, membership or sales-channel condition. Highest first. A plan listed for less than two more weeks isn't used as a retailer's rate; it's noted as "ending soon".

Time-varying and conditional offers
These rates depend on when you export, or need something first (a battery, VPP enrolment, a membership, an approved installer or a particular sales channel), so they're kept out of the table above. Retailers marked "time-varying only" above appear here.

How SA feed-in tariffs are regulated
South Australia has no regulated minimum feed-in tariff; retailers' best generally available offers run 0-8 c/kWh, with the higher rates usually limited to the first 8-10 kWh you export each day. SA's world-leading solar penetration makes midday exports nearly worthless (wholesale prices often go negative), while SA households also saw the only DMO benchmark increase in the country for 2026-27. Batteries and VPP income are where SA solar earns its keep.

What the daily cap actually means
Of the 20 retailers with a generally available flat rate above zero in SA, 6 pay it only up to a daily cap (8 kWh: 4 retailers, 5 kWh: 1 retailer and 10 kWh: 1 retailer); after the cap the rate drops to between 0.1c and 3c (inferred for 1 of them, marked * in the table). 14 pay one rate on every kWh.
For example, EnergyAustralia's 8c/kWh on the first 10 kWh a day, then 3c pays $0.80 for the first 10 kWh each day. Exporting twice that, 20 kWh, earns $1.10, because the second 10 kWh are paid at 3c. Your daily export depends on your system size, the season and how much you use during the day.
What an exported kWh is worth
Each kWh you export earns the feed-in rate. Each kWh of solar you use yourself instead saves a kWh at your plan's usage rate, which is on the plan's fact sheet. Our savings calculator estimates both for your postcode, and a home battery stores daytime solar for the evening instead of exporting it.

Common questions
What is the best solar feed-in tariff in South Australia?
On the published rate alone, the highest generally available flat feed-in tariff in the AER plan data as at 29 October 2026 is 8c/kWh on the first 10 kWh a day, then 3c from EnergyAustralia. Offers that pay more have conditions: Origin Energy's Origin Solar Partner Plus pays 12c/kWh on the first 8 kWh a day, then 2c and needs a system bought through the retailer's installer. The highest generally available time-varying rate is Flow Power's Happy Hour: 35c/kWh 5:30pm-9:30pm daily on the first 15 kWh, then 10c. It's paid only on exports in that window, so it isn't compared with the flat rates. The rate is one part of a plan: check the daily cap, the rate after it, the daily supply charge and the usage rates on the plan's fact sheet before you switch.
Who pays the highest solar feed-in tariff in South Australia?
Ranked by the flat rate open to anyone switching, in the AER plan data as at 29 October 2026: EnergyAustralia, 8c/kWh on the first 10 kWh a day, then 3c; Origin Energy, 8c/kWh on the first 8 kWh a day, then 2c; AGL, 8c/kWh on the first 8 kWh a day, then 1c; ENGIE, 8c/kWh on the first 8 kWh a day, then 1c. The table on this page ranks all 20 retailers with a flat rate above zero, highest first. Offers that need a battery, VPP enrolment or another condition can pay more and are listed separately; the plan's daily cap, supply charge and usage rates matter too.
Is there a minimum feed-in tariff in South Australia?
No regulated minimum in SA. Retailers set their own voluntary rates. Use the AER's Energy Made Easy comparison tool for the current live picture.
Should I pick the retailer with the highest feed-in tariff?
Not always. The headline FIT rate is just one factor. Check the daily cap (the rate after the cap is usually much lower), the daily supply charge, and the import (peak/off-peak) rates. A high FIT plan with a high daily supply charge and high import rates can be worse overall than a moderate FIT plan with competitive imports. Run it through the AER's Energy Made Easy comparison to compare like-for-like.
Will my feed-in tariff change over time?
Yes, it can. Retailers can change the feed-in rate on a market offer. Each retailer page shows the snapshots of the AER plan data we've recorded and any change between them; the rates on this page are from 29 October 2026.
When does the 44c feed-in tariff end in South Australia?
For anyone shopping for solar today, it has already ended. South Australia's 44 c/kWh distributor feed-in tariff only ever applied to systems connected to the grid before 30 September 2011, and it has been closed to new entrants since. You cannot get onto it by installing solar now, and you should not assume it transfers to you when you buy a house that has it, so get that in writing before it changes what you will pay. New South Australian solar customers get a retailer-set rate instead: the highest generally available flat rate in the AER plan data as at 29 October 2026 is 8c/kWh on the first 10 kWh a day, then 3c from EnergyAustralia, with no mandated minimum.
