If you’re living in Adelaide and thinking about going solar, you’ve probably heard this pitch: “Install panels, export excess energy, and get paid!” Sounds like a no-brainer, right?
But here’s what most people actually miss, while you might be paying your provider 40 to 45 cents per kilowatt-hour (kWh) to use electricity from the grid, the Adelaide solar feed-in tariff (what you earn for exporting solar back to the grid) is often just 5 to 10 cents or probably around it. Some providers offer as little as 0 cents.
Add in the fine print, like time-of-day restrictions, capped export rates, and SA solar rebates that shrink every year, and suddenly, the economics aren’t so straightforward. This article breaks down what’s really happening with feed-in tariffs in South Australia right now.
Whether you’re already generating solar power or just comparing standard electricity plans, we’ll help you figure out if exporting energy is still a smart way to save or just a shiny distraction from better ways to cut your power bill. Let’s get into it.
A solar feed-in tariff (FiT) is the actual amount your electricity retailer pays you for the solar power you send back to the grid.
It’s not fixed. It’s not government-mandated. And in South Australia, there’s no minimum rate. Instead, energy providers set their own FiTs, often with tricky conditions like daily caps or time-of-day limits.
As of July 2025, South Australia’s FiTs range from 0 to 10 cents per kilowatt-hour (c/kWh), depending on your plan and provider.
Option 1: You’re generating excess solar and exporting a lot daily
If your household doesn’t consume much power during the day, say you’re out at work, and your panels are busy exporting energy, feed-in tariffs matter. But here’s the catch:
So if you’re exporting, say, 15kWh per day, only part of it earns the high FiT. The rest gets a lower rate, and may attract a charge.
Example:
Here’s the hidden truth of solar economics: Self-consumption is king.
If you use the power your system generates (e.g., running the washing machine or AC during sunny hours), you avoid paying retail rates of 35 – 45c / kWh. That’s 3 to 5x more value than feeding it into the grid for a 5c return.
So what’s smarter?
Getting paid 5c for energy, or saving 45c by using it?
According to a July 2025 report by a Solar Calculator website, here’s how the top plans compare:
Provider | Min FiT (c/kWh) | Max FiT (c/kWh) | Conditions |
EnergyAustralia | 4.5 | 10 | Max FiT capped at 12kWh/day |
Engie | 4.0 | 10 | Max FiT capped at 8kWh/day |
Alinta Energy | 3.0 | 9 | 5kW system size limit |
Origin Energy | 2.0 | 8 | 14kWh/day cap |
AGL | 2.0 | 8 | 10kW max system size |
Diamond, Momentum | 0.0 | 2.5–3.0 | Very limited export benefit |
These look decent, until you realise electricity usage rates can offset the gains. Some plans with high FiTs may carry higher supply charges.
Yes, but they’re shrinking every year.
The SA Home Battery Scheme is no longer taking new applications, but solar panel rebates under the federal Small-scale Renewable Energy Scheme (SRES) still exist in the form of upfront STC (Small-scale Technology Certificate) discounts.
In Adelaide, this can save you $2,800 – $3,400 on a 6.6kW system, depending on panel brand and installer.
Key tip:
These rebates are built into your quote, you don’t need to apply separately. But not all installers offer the full STC value, so compare carefully.
You need a two-part strategy:
Every kWh used is a 40c saving. Every kWh exported? Just a 5–10c return.
Don’t just chase the highest feed-in tariff. The foundation of long-term savings is a low overall rate; start with a comprehensive electricity comparison in Adelaide to find the best provider for your needs. Compare:
Yes, but with different playbooks.
Most comparison sites throw you 30 tabs and wish you luck. So use Connect Market to compare electricity providers in Adelaide with solar-friendly plans weighed against real usage.
Connect Market works differently:
It’s not about switching plans. It’s about switching mindsets, from reactive bill-paying to proactive savings.
Yes, but only when you know, you actually treat them as a bonus, not the main course.
And the real savings come from smart usage, sharp plan comparison, and making solar fit your lifestyle, not the other way around.
Think of FiTs like leftover cashback on a credit card. Useful? Sure. But the big wins are in how you use the energy, not just what you get back.
Solar in Adelaide isn’t just about economics. It’s about control. In a time when energy costs are rising and environmental responsibility matters, knowing how your system interacts with your plan and with the grid, gives you real leverage.
The Adelaide solar feed-in tariff still has value. But your savings live in the margins, and that’s where Connect Market helps you thrive.
