No more dinosaur solar sales, no salesman at your door. I'll give you a straight answer using real South Australia rebates and feed in tariffs. Free, takes about a minute.
Check My South Australia Home, FreeFor a typical 6.6kW solar + 10kWh battery system on a $400-$600 quarterly bill.
These are ballpark figures for that one system size and bill combo, so you can compare against a quote. Run the actual check and I'll work out your real numbers for your bill, your roof, your usage.
Four real households, run through the same calculator this site uses for an individual report. Panels only, no battery, clean roof, someone home some of the time. Prices are after every rebate that applies in South Australia.
| Household uses | Their quarterly bill | System | After rebates | Saves a year | Pays for itself |
|---|---|---|---|---|---|
| 10 kWh | $482 | 6.6kW solar | $6,250 to $8,250 | $480–$730 | 10+ years |
| 15 kWh | $673 | 10–13kW solar | $8,000 to $13,000 | $740–$1,120 | 9–10+ years |
| 22 kWh | $941 | 10–13kW solar | $8,000 to $13,000 | $1,030–$1,540 | 6–10 years |
| 30 kWh | $1,247 | 13–15kW solar | $9,750 to $15,800 | $1,380–$2,080 | 6–9 years |
The bill column is what that household actually pays in South Australia at 42c a unit, which is why the same house has a different bill in every state. Savings depend on how much of the generation gets used on site rather than exported, and at 1c a unit for exports that is the number that decides the answer. A household out all day saves less than the figures above; one home most days saves more. Every figure is produced by the calculator, not written down, so it moves when the published rates move.
Every figure in these comes from the same calculator, using South Australia rates and rebates.
Applied automatically by your installer, doesn't matter what state you're in. On a standard 6.6kW system, around $1500 in 2026.
SA doesn't offer a state rebate either, but it does have some of the best Virtual Power Plant deals in the country if you're open to one, worth asking your installer about.
Around $2700 off a 10kWh battery through the Cheaper Home Batteries Program. You need existing or new solar panels to qualify, a standalone battery gets nothing.
Stack it all together in South Australia and you're looking at roughly $4,270 off the upfront cost of solar plus battery. That's the number I use when I run your actual report.
I worked in solar sales for a while. Watched people get talked into bigger systems than they needed, quotes that didn't add up once you did the maths, salespeople sitting in living rooms pushing a decision that day. Left because I didn't want any part of it.
So here's what's different. You run the numbers yourself first, free, no one calls you. If it stacks up, you get matched with one vetted installer, not three call centres ringing you the same afternoon. And before you sign anything, send me the quote and I'll check it myself.
My installer network is strongest in Victoria right now and growing state by state. Run the check anyway, you still get your full report either way, and I'll match you with someone as soon as I've got a vetted installer near you.

For 6.6kW solar plus a 10kWh battery on a typical bill, expect $9,730 to $15,730 once every rebate you qualify for in South Australia is applied. Bigger or smaller systems shift that number, which is why the free check uses your real bill.
Depends on your bill and your roof. South Australia gets around 5.0 peak sun hours a day. Run the free check and I'll tell you straight, for your house, not a general guess.
Yes. I don't get paid unless you're introduced to an installer and a job actually happens. If solar doesn't make sense for you, I'll tell you that instead.
Free. About a minute. No one calls you unless you ask.
