If you have solar panels or are planning to install them in South Australia (SA), understanding feed-in tariffs (FiTs) is important for maximising the value you get from your system. FiTs are the credits paid to you by your electricity retailer for excess solar electricity exported to the grid — and like many Australian states, SA’s framework involves retailer-set rates rather than a guaranteed government minimum.
⚡ What Is a Feed-In Tariff?
A feed-in tariff (FiT) is the amount in cents per kilowatt-hour (c/kWh) that a retailer pays you for exporting your surplus solar energy back into the electricity grid. These payments appear as credits on your energy bill and help offset the cost of grid electricity that you still import when your solar isn’t producing.
📜 Feed-In Tariffs in South Australia — Retailer-Based Market
In South Australia, feed-in tariffs are set by electricity retailers and are included as part of your energy plan. There is no regulated minimum FiT that retailers must match, meaning the value of your export credits depends on the individual offer from your provider.
This is similar to other states where market competition has replaced old mandated minimum tariffs — giving retailers flexibility to structure FiTs based on market design and customer incentives.
📊 Typical Feed-In Tariff Rates in SA (2026)
Feed-in tariff rates vary depending on the retailer, plan type and conditions attached, but common rates observed in South Australia as of early 2026 include:
🔹 Flat-Rate Feed-In Offers
- Typical retail FiT credits range from around 5 – 12 c/kWh for exported solar energy.
- Some plans offer bonus rates for a capped number of exported kWh per day (e.g. first 5–8 kWh).
- Other offers may be lower, closer to 4 – 6 c/kWh, depending on retailer strategy and broader retail pricing.
🔹 Time-Of-Export / Time-Of-Use FiTs
Some retailers in SA offer time-of-day feed-in tariffs, where:
- Exports during peak demand periods (often late afternoon to early evening) earn higher credits
- Midday exports from widespread solar generation may attract lower credits
- Off-peak or overnight exports may be priced differently — depending on the plan
Time-of-use FiTs can be more valuable if your solar exports align with those higher-value windows and if you pair solar with storage to export at more profitable times.
🔍 What Affects Your FiT Value in SA?
Several factors influence the actual feed-in rate you receive:
📌 Retail Energy Plan
Different retailers design FiT structures to attract solar owners — some offer higher credits but may require fixed or time-of-use tariffs, minimum usage or other conditions.
📌 Time of Export
Feed-in rates can vary by time of day under certain plans. Smart meters and time-of-use tariffs help capture higher export value in peak pricing periods.
📌 System Size & Consumption
Feed-in value may be more beneficial if your export represents a small part of generation — high self-consumption combined with modest export gives you both savings and credits.
📌 Market Conditions
Wholesale electricity prices at the time of export influence what retailers are willing to pay for solar exports — higher late-afternoon prices can support higher FiT offers.
📉 Feed-In Tariffs vs Electricity Savings
Although FiTs add value, credit rates are typically much lower than retail electricity prices in SA. That means:
- Using your own solar energy (self-consumption) is often worth more than exporting it
- If your FiT is 8 c/kWh and your grid import price is ~25–35 c/kWh, consuming your solar on-site saves more per kWh than exporting it at that FiT.
Combining solar generation with increased on-site usage — or adding a battery — maximises the portion of your solar you consume directly, delivering greater financial benefit overall.
📌 Types of Feed-In Offers to Look For
Here’s how feed-in structures commonly appear on SA plans:
🔹 Flat-Rate FiTs
A fixed credit per kWh exported, regardless of time. Simple and predictable.
🔹 Tiered FiTs
A higher credit for the first block of exported power (e.g., first 8 kWh) then a lower base rate after that.
🔹 Time-Dependent FiTs
Credits change based on time-of-day, often delivering:
- Higher credits in early evening peaks
- Lower credits around midday
These are more common on smart metered plans with time-of-use retail pricing.
📈 Tips to Make the Most of Feed-In Tariffs (SA)
✔ Compare Retailer Offers: FiT values vary between plans — checking multiple retailers can find better credits and terms.
✔ Understand Conditions: Some plans have caps, daily limits or requirements like minimum consumption.
✔ Track Export Patterns: Understanding when your solar exports most helps match tariffs to value times.
✔ Use More Solar On-Site: Even with reasonable FiTs, using your own solar directly usually delivers greater savings.
✔ Consider Adding a Battery: Solar storage increases self-consumption and lets you export at higher value times if your retailer supports time-of-use export rates.
