SA solar battery rebate
SA solar battery rebate 2026: how much you can get and who qualifies
30-second answer: every eligible South Australian home can get about $3,400 off a 13.5 kWh battery through the federal Cheaper Home Batteries discount, taken off the installer’s invoice. That rate steps down on 1 January 2027, so installs finished this year get more. Priority households can add up to about $2,050 from the state REPS incentive for joining a Virtual Power Plant, and homes in postcodes 5000 and 5006 can add a City of Adelaide rebate of up to $1,000. Check your postcode to see what may apply.

Every eligible South Australian home can get around 30% off a new battery through the federal Cheaper Home Batteries discount, taken off the installer's invoice: about $2,500 on 10 kWh and $3,400 on 13.5 kWh at mid-2026 certificate prices. Priority households can add an SA REPS payment for joining a Virtual Power Plant, and homes in the City of Adelaide can add a council rebate on top. The old state-run Home Battery Scheme has ended; the federal discount took its place and is worth more for most homes.
Solar battery prices in Adelaide after the rebate
How much is a solar battery in South Australia? Most Adelaide homes are quoted between about $9,000 and $19,000 installed, depending on size, brand and switchboard work. The federal discount comes straight off that price, so the figure you actually pay is lower than most price guides show.
| Usable capacity | Typical Adelaide installed price before discount | Federal discount | Typical price after discount |
|---|---|---|---|
| 10 kWh | around $9,000 to $11,000 | about $2,500 | around $6,500 to $8,500 |
| 13.5 kWh | around $12,000 to $14,000 | about $3,400 | around $8,600 to $10,600 |
| 20 kWh | around $16,000 to $19,000 | about $4,400 | around $11,600 to $14,600 |
Indicative only. Prices are typical ranges for an Adelaide metro install and vary with brand, backup wiring and switchboard upgrades. The discount uses mid-2026 certificate prices of roughly $250 per usable kWh on the first 14 kWh and about $150 per kWh from 14 to 28 kWh. Priority households that secure a REPS payment, and City of Adelaide residents, can take more off. Your installer confirms the actual figure for your battery and install date.
The discount is set by the date your battery is installed and commissioned, not the date you sign. On 1 January 2027 it drops by about 16%: roughly $2,850 on a 13.5 kWh battery instead of $3,400, about $550 less. To be installed before then, most homes need to sign by early November. The battery rebate changes page sets out every step-down to 2030, and the battery rebate calculator works out the figure for your size.
What battery support may be available in SA now
South Australian households can combine the federal battery discount with a state VPP incentive and, in the CBD and North Adelaide, a council rebate. SA also has some of the highest power prices in the country, so batteries tend to deliver strong value here.
| Pathway | Status | Indicative support | Notes |
|---|---|---|---|
| Federal Cheaper Home Batteries | Open (tiered from 1 May 2026) | ~30% off; about $250 per usable kWh on the first 14 kWh | Battery must be paired with solar; next step-down 1 January 2027 |
| REPS VPP incentive | Priority households only (general funding exhausted May 2026) | Priority: up to ~$1,030 (13 kWh) or ~$2,050 (28 kWh). General households when funded: up to ~$670 (13 kWh) or ~$1,560 (28 kWh) | Offered by REPS providers at their discretion; requires joining an approved VPP; general funding expected back in early 2027 |
| City of Adelaide battery rebate | Listed (postcodes 5000 & 5006) | 50% of remaining cost up to $1,000 | Calculated after all other rebates; limited annual budget, so lodge a pre-commitment before installing |
| SA Home Battery Scheme | Closed | None now | Closed to new applications in 2022 |
Figures are indicative and change regularly. REPS is not a fixed government rebate: energy retailers and accredited providers choose which activities they offer and at what value, so treat "up to $2,050" as a provider and eligibility dependent offer, not an entitlement. Confirm current availability before installing.
How the stack works
The federal Cheaper Home Batteries discount is the largest upfront saving for most households: roughly $2,500 on a 10 kWh battery and $3,400 on 13.5 kWh at current certificate prices. On top of that, joining an approved Virtual Power Plant through the Retailer Energy Productivity Scheme (REPS) may add an incentive. If you live in postcode 5000 or 5006, the City of Adelaide battery rebate page covers the council layer. Some VPP participants also receive a small annual bill credit.
SA government battery rebate: what the state pays in 2026
The SA government no longer runs a direct battery subsidy. Its support now comes through the Retailer Energy Productivity Scheme (REPS), which requires energy retailers to fund upgrades. One REPS activity pays a one-off amount when an eligible battery is connected to an approved Virtual Power Plant, scaled by battery capacity up to a cap.
| Household | 13 kWh battery | 28 kWh battery (cap) | Status in 2026 |
|---|---|---|---|
| Priority household | up to about $1,030 | up to about $2,050 | Open, provider by provider |
| General household | up to about $670 | up to about $1,560 | Paused: funding exhausted May 2026, expected back early 2027 |
Retailers have an annual target, and in 2026 the general-household allocation was used up in May, so at the time of writing providers are accepting priority-group households only. The priority group generally includes holders of a Pensioner Concession Card or Health Care Card, households receiving an SA Government energy concession or on a retailer hardship or payment plan, households referred by a SAFCA financial counsellor, and renters paying $500 a week or less. If you are not in the priority group, plan the purchase around the federal discount, which drops on 1 January 2027, and treat any REPS payment as a bonus if funding returns before you install.
Typically requires an SA property, an approved battery on the SA Power Networks list, an accredited installer, and (for the REPS incentive) joining an approved VPP with a provider that still has REPS allocation for your household type. The federal discount generally requires the battery to be paired with new or existing solar, 5 to 100 kWh, VPP-capable and installed by an accredited installer; it has no income test. Final eligibility depends on current scheme rules.

Indicatively, a 10 kWh battery is around $9,000 to $11,000 installed in Adelaide, 13.5 kWh around $12,000 to $14,000 and 20 kWh around $16,000 to $19,000. After the federal discount that is roughly $6,500 to $8,500, $8,600 to $10,600 and $11,600 to $14,600. Brand, backup wiring and switchboard work move the price, so compare written quotes.
Indicatively: the federal discount of about $250 per usable kWh on the first 14 kWh (about $3,400 on 13.5 kWh), plus a REPS VPP incentive if a provider has allocation for your household (priority households up to about $1,030 on 13 kWh or $2,050 on 28 kWh), plus a City of Adelaide rebate of 50% up to $1,000 in postcodes 5000 and 5006. Amounts and rules change; verify before installing.
The federal discount falls by about 16% on 1 January 2027: roughly $2,100 instead of $2,500 on 10 kWh, $2,850 instead of $3,400 on 13.5 kWh and $3,700 instead of $4,400 on 20 kWh. It is set by the install date, not the quote date, and steps down again every six months to 2030. See battery rebate changes for the full schedule.
The federal Cheaper Home Batteries discount, open to every eligible SA home with no income test, is now the main saving and is worth more than the old scheme for most homes. The state adds a REPS VPP incentive (priority households only until new funding arrives, expected early 2027), and the City of Adelaide adds a council rebate in 5000 and 5006. The SA Home Battery Scheme itself closed to new applications in 2022.
Only for priority-group households at the time of writing. The 2026 general-household funding was exhausted in May 2026 and is expected to be replenished in early 2027. Retailers and accredited providers decide which REPS activities they offer, so availability also varies by provider.
Generally: holders of a Pensioner Concession Card or Health Care Card, households receiving an SA Government energy concession, households on a retailer hardship program or payment plan, households referred by a South Australian Financial Counsellors Association member, and renters paying $500 a week or less. Your provider confirms the current definition.
Through REPS, priority households can receive up to about $1,030 on a 13 kWh battery and up to about $2,050 on 28 kWh or more. When general funding is open, other households can receive up to about $670 (13 kWh) or $1,560 (28 kWh). The battery must join an approved VPP, and providers set the final amount.
The REPS incentive requires joining an approved Virtual Power Plant; that is what it pays for. The federal discount does not require a VPP, but the battery must be VPP-capable and paired with solar.
Only inside the City of Adelaide council area (postcodes 5000 and 5006), where the Sustainability Incentives Scheme pays 50% of your remaining cost up to $1,000, calculated after other rebates. See the City of Adelaide battery rebate page. Other Adelaide suburbs get the federal discount and, for priority households, REPS.
Businesses may access the federal battery discount, solar incentives and certain REPS activities (a small-business REPS VPP rate also exists). Submit a commercial enquiry and we'll review what may apply.
