Finding the Best Solar Feed-In Tariff in South Australia for 2026

South Australian solar feed-in tariffs vary widely by retailer and plan. As checked on 3 August 2026, some standing offers pay 0c/kWh, standard retailer rates include approximately 0.5c to 3c/kWh, and selected solar plans offer 8c/kWh for a limited daily export amount before reverting to a lower rate.

These credits are much lower than South Australia's current standing-offer import rates. From 1 July 2026, the regulated flat-rate residential standing-offer cap is 41.91c/kWh, while the time-of-use cap ranges from 17.04c/kWh during the 10am–4pm solar-soak period to 56.22c/kWh during morning and evening peak periods. These are Default Market Offer caps rather than market-offer averages.

The best solar feed-in tariff in SA is therefore not necessarily the plan with the highest advertised export rate. Compare the FiT, export cap, grid-import rates, daily supply charge, and your household's import and export patterns.

Key Takeaways

• Some 2026 SA plans pay 0c/kWh, while selected solar plans offer 8c/kWh for a limited export block.

• South Australia has had no regulated minimum retailer FiT since 1 January 2017.

• SA Power Networks' export tariff differs for interval and accumulation meters.

• Eligible systems connected or approved before 1 October 2011 may retain the legacy 44c/kWh rate until 30 June 2028.

• Directly using solar can be worth more than exporting it when grid-import rates substantially exceed the FiT.

• A battery may increase self-consumption, but its value depends on efficiency, forgone FiT, installed cost, degradation, and household demand.

The South Australian Solar FiT Market in 2026

South Australia has one of the world's highest rates of rooftop-solar adoption. Large volumes of midday exports can reduce wholesale electricity prices and the value retailers place on exported solar.

Since 1 January 2017, South Australia has had no regulated minimum retailer feed-in tariff. Retailers set their own rates and may offer flat, tiered, capped, or zero-credit structures. See the Essential Services Commission of South Australia's feed-in tariff review.

Legacy 44c Feed-In Tariff

The distributor-funded 44c/kWh feed-in tariff remains available to certain eligible systems that were connected, or had received distributor approval to connect, before 1 October 2011.

The scheme is scheduled to end on 30 June 2028, subject to continued eligibility. System changes may affect access, so customers receiving the legacy tariff should contact SA Power Networks before altering their solar or battery setup. See ESCOSA's solar feed-in scheme information.

Midday Wholesale Conditions

Low or negative midday prices can coexist with high quarterly average prices when heatwaves, low renewable output, network constraints, or extreme price events occur at other times.

The Australian Energy Regulator's Q1 2026 report recorded a South Australian volume-weighted average wholesale price of $144/MWh, up from $98/MWh a year earlier. Most negatively priced periods occurred in South Australia and Victoria, while extreme SA price events raised the quarterly average.

SA Power Networks' Export Tariff

SA Power Networks charges the retailer rather than billing the household directly. Whether the cost affects the customer's FiT or appears as a separate charge depends on the retailer's plan structure.

For interval-meter customers, exports outside 10am–4pm do not attract the network export tariff.

A household with lower exports may remain within its accumulated allowance, but system size alone does not determine whether a charge applies. SA Power Networks estimates an average impact of about $1.50 per month for its representative 5kW residential system.

Retailer export caps are separate commercial conditions. For example, a retailer may pay a higher FiT for the first 8kWh or 10kWh exported per day. That cap is not the same as SA Power Networks' 9kWh interval-meter allowance.

See the SA Power Networks export-tariff guidance.

Comparing Current SA Solar Plans

The following examples were checked on 3 August 2026. They are not an exhaustive list, and availability may depend on postcode, meter type, inverter size, and eligibility.

There is no universal winner. A household exporting less than 8kWh per day may benefit from a boosted FiT, while a household importing substantial evening electricity may save more through lower usage and supply charges.

Use Energy Made Easy for postcode-specific comparisons because rates and eligibility can change frequently.

These are regulated standing-offer caps. Market offers may use different rates, time periods, discounts, or demand charges. See the Australian Energy Regulator's Default Market Offer information.

When comparing plans, check:

Using Solar Directly vs Exporting It

Direct self-consumption is worth the grid purchase avoided minus the feed-in payment forgone.

Using the flat-rate SA standing offer as an example:

• Import rate avoided: 41.91c/kWh

• Assumed FiT forgone: 3c/kWh

41.91c − 3c = 38.91c

Using 1kWh of solar directly instead of exporting it improves the household's position by approximately 38.91c in this example.

Flexible loads such as dishwashers, washing machines, electric hot water, pool pumps, and EV charging can often be scheduled during solar-production hours.

When Battery Storage May Help

Directly using solar avoids battery conversion losses and requires no battery investment. A battery may add value when substantial midday exports coincide with high evening consumption.

Its economics should include:

• Round-trip efficiency

• Forgone feed-in credits

• Installed and financing costs

• Battery degradation

• Evening import prices

• Household demand

• Available usable capacity

Battery-Shifting Example

Assume:

• 1kWh of midday solar is stored.

• Round-trip efficiency is 90%.

• Evening import rate is 50c/kWh.

• Forgone FiT is 3c/kWh.

Energy returned:

1kWh × 90% = 0.9kWh

Avoided evening cost:

0.9kWh × $0.50 = $0.45

Gross value after the forgone FiT:

$0.45 − $0.03 = $0.42

The gross shifting value is approximately 42c per solar kilowatt-hour stored, before degradation, installation, financing, and other system costs.

Complete Control with BLUETTI Home Energy Storage

BLUETTI home battery systems can store solar energy for later use, reduce evening grid imports, and supply selected backup circuits when correctly designed and installed.

BLUETTI EP760

The BLUETTI EP760 is designed for single-phase residential installations, subject to site and load assessment.

It supports:

• Up to 7,600W rated AC output

• Up to 13,500Wp recommended PV array

• Three independent MPPT inputs

• Modular B500 battery storage

• Backup switchover in under 10ms

BLUETTI states that the 7,600W configuration can cover more than 95% of typical household energy needs and that a suitably sized system may achieve up to 80% energy self-sufficiency.

These are potential results rather than guarantees. Actual performance depends on solar generation, battery size, connected loads, backup circuits, and installation design.

BLUETTI EP2000

The BLUETTI EP2000 is an installed three-phase system for higher-demand residential applications.

It supports:

• 14.7–51.6kWh using two to seven B700 batteries

• Up to 20kW rated output

• Up to 30kW maximum PV input

• A recommended solar array of up to 40kWp

• Up to three systems in parallel for a maximum of 60kW

BLUETTI states that a suitably configured EP2000 may reduce grid reliance by up to 90%. Actual results depend on solar generation, storage capacity, loads, phase balance, and system design.

A three-phase property or EV charger does not automatically require an EP2000. The appropriate system should be determined through a site and load assessment.

Installation, Warranty, and Rebate Considerations

EP760 and EP2000 systems require professional design and installation by appropriately licensed and accredited professionals.

Before purchasing, confirm:

• Nominal and usable capacity

• Inverter and backup output

• Backup circuits

• Round-trip efficiency

• Solar and switchboard compatibility

• Installation costs

• FiT eligibility

• Warranty conditions

• Savings and payback assumptions

Cheaper Home Batteries Program

The Australian Government's Cheaper Home Batteries Program provides an upfront discount on eligible batteries connected to new or existing rooftop solar.

Only the first 50kWh of usable capacity is eligible for small-scale technology certificates.

For installations from 1 May 2026, support is tiered:

• 0–14kWh: 100% of the applicable STC factor

• Above 14–28kWh: 60%

• Above 28–50kWh: 15%

The discount depends on usable capacity, installation date, STC factor, and certificate value. Larger systems may remain eligible, but support per additional kilowatt-hour falls above 14kWh and again above 28kWh.

Creating Your Household Energy Plan

Start with at least 12 months of household import and export data.

1. Compare complete retailer plans through Energy Made Easy.

2. Identify appliances that can use solar directly.

3. Check whether exports exceed the SA Power Networks allowance.

4. Estimate battery-shifting value after efficiency losses and forgone FiT.

5. Size storage around evening demand rather than total panel output.

6. Compare installed costs with realistic annual savings.

A boosted FiT may suit a household that exports substantial solar. A lower-FiT plan may be better when it offers cheaper import rates or supply charges. Battery storage may help where midday exports and evening demand are both high, but plan comparison and direct self-consumption should be assessed first.

What is the SA Power Networks export charge?

For interval or smart meters, SA Power Networks charges the retailer 1c/kWh for exports above the accumulated allowance of 9kWh per day between 10am and 4pm.

For accumulation meters, it charges the retailer 0.75c/kWh above the accumulated allowance of 11kWh per day.

Unused allowances can roll over within the billing cycle. Whether the customer sees the charge depends on the retailer.

Does South Australia have a minimum solar feed-in tariff?

No. Since 1 January 2017, retailers have set their own rates and tariff structures.

Does a high solar FiT mean I do not need a battery?

Not necessarily. A high capped FiT may suit households with large exports, while a battery may suit homes with high midday exports and evening demand.

Compare direct self-consumption, export income, battery efficiency, installed cost, and degradation before deciding.

Is using solar directly more valuable than exporting it?

It often is when the import rate is much higher than the FiT.

At an import rate of 41.91c/kWh and a 3c/kWh FiT, directly using 1kWh of solar instead of exporting it improves the household's position by approximately 38.91c.
