Thousands of Australian homeowners are adding a battery to their solar this year, most with no upfront cost finance. They store their cheap daytime solar to use through evening peak prices, and many earn extra by exporting through Virtual Power Plant (VPP) programs.
We got ripped off on solar. So we learned everything, so you don't have to.
We set out to power our own home with the sun. We did our homework, we trusted the installer who seemed different from the rest, and we paid close to $100,000. We were charged for German batteries and handed cheap knock-offs. The system couldn't get through a normal week, and we spent five years putting it right.
Then we realised our story wasn't rare. Around one in three Australian solar systems is now an orphan, abandoned by the company that installed it. So we built Why Solar to make sure what happened to us stops with us. We don't sell solar. We vet the installers, and we tell you the truth, even when it earns us nothing.
What homeowners say
Real reviews from Australians who used Why Solar to find their installer.
“Finally, solar advice I can actually trust. No pressure, no pushy sales stuff, just straight up honest info.”
Jasmine
“Spent a few weeks going through this site before installing. Now charging the car off the sun most days. Setup's paying for itself faster than I expected.”
HLR Photography
“They're completely independent, so I felt like I was getting advice that was actually in my best interest.”
Alice
“Really great business to deal with, they saved me so much time and hassle. Would recommend!”
Addy A.
Every installer clears all six checks
A warranty is only as good as the company behind it. Before an installer earns Why Solar approval, they pass every one of these. Most don't.
Credentials
Accreditation and licensing, current and genuine, checked rather than assumed.
Staying power
Years actually trading, and the financial stability to still be here in a decade to honour what they promise.
Proof of work
Real installations we can examine, not a folder of stock photos and slogans.
The actual hands
Who physically turns up to do the job, not the cheapest available subcontractor.
What goes in
Genuine, traceable components that match the quote exactly. No quoting German and fitting Chinese.
How they handle trouble
How they behave when something goes wrong. That, not the sales call, is the true measure of a company.
South Australia solar & battery rebates in 2026
Households in South Australia can currently stack two federal programs: the solar STC rebate, which comes off your quote up front, and the Cheaper Home Batteries discount on the battery. Here is what that is worth on one specific system, a 13.3kW single-phase solar array with a 14kWh battery, which is the largest setup a normal single-phase home can install.
| Rebate | Worth in SA |
|---|---|
| Federal solar rebate (STCs)13.3kW single-phase system, STC Zone 3 (multiplier 1.382), 5-year 2026 deeming period = 91 certificates at $38 each | $3,458 |
| Federal Cheaper Home Batteries Program14kWh usable battery, STC factor 6.8 (full rate on the first 14kWh) = 95 certificates at $38 each | $3,610 |
| SA state top-up | None currently |
| Total on this system | $7,068 |
Other SA incentives, and who actually qualifies
These are real, but they are conditional, so they are deliberately left out of the total above. Check the conditions before you count on one.
- REPS Virtual Power Plant incentive: up to $2,050(currently restricted)
- Currently limited to priority applicants such as concession card holders and tenants, with general household funding exhausted
- The maximum $2,050 requires a battery of around 28kWh, far larger than a typical home battery
- The battery must be connected to an approved Virtual Power Plant
- The incentive is applied by the VPP operator as a discount, not paid to you
- City of Adelaide council battery rebate: up to $1,000
- 50% of the installed cost, capped at $1,000
- City of Adelaide council area only, which is postcodes 5000 and 5006
- The battery must be coupled with a solar PV system
The SA Home Battery Scheme closed to new applications in 2022, so SA households claim the federal programs. South Australia’s remaining incentives are conditional rather than automatic: see the notes below the table.
The federal battery rebate steps down next on 1 January 2027, and the STC deeming period shortens every January until the program ends in 2030, so the same system attracts a little less rebate each year you wait. Take the 60-second quiz above for a personalised estimate of the rebates you can claim.
The federal solar rebate is not a cash payment from government. It is a number of small-scale technology certificates (STCs) your system creates, which your installer trades and applies to your quote as an upfront discount. The value moves with the certificate market.
All quotes, savings estimates, and rebate calculations provided through our website are indicative only. Final pricing and rebate amounts will be confirmed by your assigned installer following a site assessment. Actual savings may vary based on energy usage, system performance, and electricity rates.

Why solar stacks up in Adelaide
South Australians pay some of the highest power prices in the country, and that is exactly what makes solar work so hard here: every kilowatt-hour your panels produce replaces one of the most expensive kilowatt-hours in Australia. Adelaide sits in STC Zone 3, where the federal rebate on a 13.3kW single-phase install comes to $3,458, and the federal Cheaper Home Batteries Program takes $3,610 off a 14kWh battery on top. Together that is $7,068 off a full solar and battery install.
Those two federal programs are the ones almost every South Australian household can actually claim. South Australia does have more on paper, a Virtual Power Plant incentive and a City of Adelaide council rebate, but both come with conditions that rule most households out right now. We have set them out honestly in the table above rather than folding them into a headline number you may never see.
You can see how the programs work on our South Australia rebates page and the federal rebate guide, or just take the 60-second quiz above and get the numbers for your own address.
The world's rooftop solar capital plays by its own rules
South Australia has more rooftop solar per household than anywhere in the world, and the grid has had to adapt. SA Power Networks now requires new installations to be capable of flexible exports. Whether you actually use them is your choice, and the choice is worth more than most people realise. Opt in and your export limit moves with grid conditions, from 0 up to 10kW per phase. Stay on the fixed alternative and you are capped at 1.5kW, or at zero export on some connections.
That changes what a good install looks like. Your inverter has to support dynamic export control, the connection has to be registered correctly with SA Power Networks, and the system should be designed so curtailed energy goes into a battery instead of being lost. The vetted local installers we match you with handle the SA connection rules as their everyday standard, and are still around if you ever need warranty support.
Batteries earn their keep in South Australia
A battery in Adelaide does the usual job of storing cheap daytime solar to run the evening peak. SA is also the heartland of the Virtual Power Plant: sign your battery up to a VPP such as the Tesla Energy Plan, AGL VPP or Origin Loop and it earns credits by supporting the grid during price spikes.
There is also a REPS incentive of up to $2,050 for connecting an eligible battery to a VPP, but be careful with that number. General household funding is currently exhausted, and applications are limited to priority applicants such as concession card holders and tenants. The full $2,050 also assumes a battery of around 28kWh, several times the size of a typical home battery. If you are an owner-occupier putting in a normal battery, plan your numbers without it and treat it as upside if you qualify.
SA retailers price for storage anyway: several offer a "solar sponge" tariff with cheap electricity in the middle of the day, when the state's rooftop solar floods the grid, and steep prices in the evening. With feed-in tariffs for plain exports sitting around 5 to 8 cents, the money in SA solar has shifted from exporting to storing. Your installer sets up the battery, any VPP enrolment and the SA Power Networks paperwork as part of the job.

Solar in Adelaide: common questions
How much is the solar rebate in Adelaide in 2026?
Adelaide sits in STC Zone 3. A 13.3kW single-phase system, the largest a normal single-phase home can install, creates enough small-scale technology certificates to be worth $3,458 at the current certificate price, and the federal Cheaper Home Batteries Program takes $3,610 off a 14kWh battery on top. That is $7,068 on that system. Those are the two federal programs almost every South Australian household can claim. The quiz above shows the figure for your own home.
Is there a South Australian state rebate on top of the federal ones?
Not one a typical owner-occupier can count on. The SA Home Battery Scheme closed to new applications in 2022, so the heavy lifting is now done by the federal programs: STCs for panels and the Cheaper Home Batteries Program for storage. South Australia does still run the REPS Virtual Power Plant incentive, worth up to $2,050, but general household funding is currently exhausted and applications are limited to priority applicants such as concession card holders and tenants. The maximum amount also requires a battery of around 28kWh, several times a typical home battery. Treat it as a bonus to check, not as money to budget for.
Can City of Adelaide residents claim a council battery rebate?
Some can. The City of Adelaide rebate pays 50% of the installed cost capped at $1,000, and the battery has to be coupled with a solar PV system. It applies to the City of Adelaide council area only, which is postcodes 5000 and 5006. Most of the metro area we cover, from Gawler and Elizabeth down to Seaford, and the Adelaide Hills, sits outside that council area and does not qualify, which is why we leave it out of the rebate totals on this page.
What are flexible exports and how do they affect my solar?
South Australia has more rooftop solar per household than anywhere in the world, and SA Power Networks manages that by requiring new installations to be capable of flexible exports. Taking them up is your choice. Opt in and your export limit varies with grid conditions, anywhere from 0 up to 10kW per phase. Stay on the fixed alternative and you are capped at 1.5kW, or zero export on some connections. That is a much bigger gap than most people realise, and it is one more piece of connection paperwork your installer needs to get right, which is why we match you with a vetted local installer who does it every week.
What does a solar system cost in Adelaide?
Most quality 6.6kW systems in Adelaide land between $4,500 and $8,000 after rebates, depending on panels, inverter and roof complexity. A solar and battery package typically runs $10,000 to $17,000 after the federal battery discount. With SA power prices among the highest in the country, payback periods of three to five years are common. $0 upfront finance is widely available.
