A 2026 NSW homeowner’s guide to comparing battery savings against export earnings
Every NSW solar owner eventually asks the same question. Should you export your surplus power for a feed-in tariff credit or store it in a battery for later use? In 2026, that question matters more than ever. Feed-in tariffs have been falling for years. At the same time, the federal Cheaper Home Batteries Program has reduced eligible battery upfront costs by roughly 30%. This guide explains the real numbers behind both options. It will help you decide which choice could save you more money on your NSW electricity bill.
What Is a Feed-In Tariff, and How Has It Changed in 2026?
A feed-in tariff (FiT) is the credit your electricity retailer pays for each kilowatt-hour of surplus solar energy you export to the grid. NSW removed its mandatory minimum FiT in 2016. Since then, retailers have set their own rates. Some now pay as little as zero.
The Independent Pricing and Regulatory Tribunal (IPART) publishes an annual benchmark that shows what a fair feed-in tariff looks like. For 2025–26, the benchmark ranges from 4.8c to 7.3c/kWh. From 1 July 2026, it is set to fall further to between 3.4c and 6.5c/kWh. In practice, some retailers already offer lower rates. EnergyAustralia has reduced its flat NSW feed-in tariff to 3c/kWh. AGL has removed feed-in tariffs for customers on standard retail contracts. Meanwhile, Alinta Energy and GloBird Energy still offer up to 10c/kWh on selected plans. Market-linked retailer Amber Electric can occasionally pay more than 25c/kWh during periods of peak demand.
That spread, from 0c to 10c on standard plans and far higher on volatile market plans, is exactly why a single ‘feed-in tariff’ figure means very little without checking your own retailer’s rate first.
How Much Is Your Solar Export Really Worth?
To compare fairly, it helps to see every pathway for your solar energy side by side: exporting on a standard plan, exporting on a premium plan, and self-consuming through a battery. The chart below lays out typical 2026 NSW figures for each.
The pattern is consistent across almost every NSW retailer: exporting electricity earns far less than not buying it back later. NSW households typically pay 29c to 37c/kWh for grid electricity, depending on network and time of use. So every kilowatt-hour you store and use yourself is effectively worth three to ten times what the same kilowatt-hour earns as an export credit.
This is the core economic shift driving battery uptake. Solar batteries do not just back up your home during an outage; they let you capture the gap between what retailers pay you for exports and what they charge you for imports.
How a Solar Battery Changes the Maths
A home battery stores your excess daytime solar generation and discharges it in the evening, when grid electricity is most expensive and feed-in rates no longer apply. For a typical 10kWh battery, that can mean covering most of an average household’s evening and overnight usage without touching the grid.
Under the federal Cheaper Home Batteries Program, eligible solar batteries installed in 2026 attract a discount of roughly 30% on the upfront cost, with the first 14kWh of usable capacity receiving the full rebate rate. A 10kWh battery, for example, can see several thousand dollars come off the sticker price before installation. NSW households can also stack the state’s Virtual Power Plant (VPP) incentive, worth up to $1,500, on top of the federal discount when they connect an eligible battery to a VPP program. Stacked together, these incentives mean many NSW households now reach battery payback in well under ten years, a dramatic shift from the 15-plus year paybacks common just a few years ago
Real-World Example: Comparing Both Paths in Bankstown
Consider a typical home running a 6.6kW solar system in Bankstown, exporting around 12kWh of surplus solar daily. On a standard 6.5c/kWh feed-in tariff, that household earns roughly $0.78 a day, or about $285 a year, in export credits.
Now compare this to adding a 10kWh solar battery. If the same household stores 12kWh of surplus energy in the battery and uses it during evening peak hours, it avoids buying grid electricity at about 33c/kWh. The daily saving is around $3.96. That equals roughly $1,445 per year. The federal rebate and NSW VPP incentive can reduce the upfront battery cost. As a result, many Bankstown households recover their investment in six to eight years. After that, they continue saving on every evening kilowatt-hour.
This is why, for most NSW homes with meaningful evening electricity use, pairing solar batteries with the right-sized system tends to outperform relying on feed-in tariffs alone, even where the headline rebate news focuses on the upfront battery rebate rather than the ongoing import savings.
Solar Battery vs Feed-In Tariff: A Decision Framework
There is no single right answer for every household. Use the framework below to work out which option fits your situation.
- Check your current feed-in rate first. If it is below the IPART benchmark of roughly 6c/kWh, a battery almost always saves more money than continuing to export.
- Map your usage pattern. Households with high evening or overnight electricity use benefit most from storing solar rather than exporting it.
- Factor in the rebate timing. The federal battery rebate steps down every six months, so installing sooner generally means a larger discount.
- Get quotes from a Clean Energy Council-accredited installer. The best solar battery installer for your home will model your specific usage data rather than relying on generic averages.
If you are still unsure, request a tailored quote. A qualified solar battery specialist can model your actual export and consumption data, rather than relying on averages, to show your real payback period.
Frequently Asked Questions
If you are on a genuinely high, capped-rate plan, such as a premium retailer offer that pays 10c/kWh or more on the first block of exports, the gap becomes smaller. Even then, self-consumption usually delivers greater savings. That’s because evening electricity usage is still expensive. Import rates remain much higher than even the best premium export rates.
IPART’s own benchmark is scheduled to fall to 3.4-6.5c/kWh from 1 July 2026, and several major retailers have already cut rates or removed FiTs for standard contracts. The long-term trend points downward as more rooftop solar floods the grid at midday.
The rebate currently reduces the upfront cost of an eligible battery by around 30% for the first 14kWh of usable capacity. Larger systems receive a lower level of support. The exact rebate amount depends on your battery size and the STC rate at the time of installation. Check the latest figures with your installer before signing any agreement.
Yes. The NSW Solar Sharer offer gives eligible smart-meter households three free hours of electricity around midday. A battery complements this by capturing any solar you generate beyond your midday usage and shifting it to cover the evening peak, when the free-hours window has ended.
Most three-to-four-person Bankstown households see strong results from a 10-13kWh battery paired with a 6.6-10kW solar system, though the right size depends on your evening usage pattern and existing system output.
