# Solar Feed-In Tariff vs Battery Storage: Which Saves You More in NSW?

![](https://resinc.com.au/wp-content/uploads/2026/08/16.01.2026_RESINC_Alex_Volkanovski_00-53.jpeg)

For a lot of NSW households, storing solar energy for home use delivers better financial value than relying on feed-in tariffs alone. But it isn’t automatic. It depends on how much you export, how much power you use in the evening, your battery size, your tariff structure and the cost of installation. Feed-in tariff rates in NSW often sit around 5-8 cents per kWh, while buying electricity back typically costs 30-40 cents. That gap is real, but whether closing it with a battery pays off depends on your household.

## Key Takeaways

- NSW feed-in tariff rates are often around 5-8 cents per kWh, well below the 30-40 cents per kWh you typically pay for grid electricity (source: resinc.com.au). Compare current rates at energymadeeasy.gov.au.
- Solar and battery storage lets you self-consume power at night instead of exporting it at a low rate, but round-trip efficiency losses and reserve settings mean it’s never a 1:1 exchange.
- Whether a battery beats relying on feed-in tariffs depends on your export volume, evening usage, tariff structure and battery size, not a blanket rule.
- The Cheaper Home Batteries Program may reduce battery installation costs for eligible households. Rebate values change every 6 months. Verify current figures with our team before making a final decision.
- Time-of-use tariffs and virtual power plant (VPP) participation can shift the store-vs-export decision in either direction.

## Introduction

When solar was first installed across a lot of Australian homes, feed-in tariffs were genuinely attractive. Some early adopters were getting well over 40 cents per kilowatt-hour for exported power.

Those days are behind us. In NSW today, feed-in tariff rates are often around 5-8 cents per kWh, while grid electricity purchase rates typically sit at 30-40 cents per kWh (source: resinc.com.au). You can compare current retailer rates at energymadeeasy.gov.au. That gap matters if your system is exporting a meaningful amount of power every day.

From our experience, this is exactly why more NSW homeowners with existing solar are looking at battery storage. A battery isn’t automatically the better option for every household though. It depends on your specific usage pattern, and we’ll get into what actually drives that decision.

## What Is a Solar Feed-In Tariff and What Are NSW Rates in 2026?

A feed-in tariff is the rate your electricity retailer pays for solar power you export to the grid. When your panels produce more than your home needs at that moment, the surplus is sent to the grid and credited on your bill.

In NSW, voluntary feed-in tariff rates from major retailers are often around 5-8 cents per kWh (source: resinc.com.au). Some retailers offer time-varying export tariffs that pay more during peak demand windows. Rates differ by retailer and plan, so always check your own bill or compare offers at energymadeeasy.gov.au.

**How does NSW compare to what you pay for electricity?**

|  | **Rate (approximate, NSW 2026)** |
|---|---|
| Feed-in tariff (export rate) | Often around 5-8 cents per kWh |
| Grid electricity purchase rate | Typically 30-40 cents per kWh |

That gap is the core reason battery storage gets a serious look. For a home exporting a meaningful volume of solar daily, the difference adds up over a year, though the exact impact depends on your export volume and tariff.

## The Real Cost of Exporting Solar Instead of Using It

Let’s put some numbers to this.

Say a solar system produces 20 kWh on an average day. The home uses 10 kWh during daylight hours, and the other 10 kWh gets exported.

At a 6 cent feed-in tariff, that’s around 60 cents earned for those 10 units. That evening, if the household draws 8 kWh from the grid at 35 cents per kWh, that’s roughly $2.80.

So 10 kWh was exported for about 60 cents, then 8 kWh was bought back for about $2.80. As an illustrative comparison only, using that stored power instead of exporting it could be worth several times more than the feed-in credit received, though a battery never captures 100% of that value. Round-trip efficiency losses (typically 95-97% depending on the battery), reserve settings that hold back a portion of charge for backup, and day-to-day seasonal variation all mean a battery won’t fully charge or fully offset usage every single day.

**Is it better to store solar or sell it back to the grid in NSW?**

For many NSW households, storing solar and self-consuming it delivers more value than exporting it at current feed-in tariff rates, because grid purchase rates are typically much higher than export rates. But this isn’t universal. Households with low evening usage, limited surplus, or a favourable time-varying export tariff may find the gap between the two options is smaller than it looks on paper.

## How Battery Storage Changes the Equation

A solar battery storage system doesn’t generate more electricity. It changes how much of your solar production you actually use yourself.

Without a battery, self-consumption, the share of solar production used directly, is often lower for households that are out during the day, with the rest exported. With a battery, self-consumption typically rises, though the exact increase depends on battery size, reserve settings and household usage patterns. It’s rarely close to 100%, because reserve capacity, standby losses and days of lower solar generation all play a part.

What generally changes:

- Solar power your home can’t use immediately gets stored instead of exported.
- In the evening, the battery discharges to power the home instead of drawing from the grid, subject to how much charge it holds that day.
- You draw from the grid mainly once solar production and battery charge are both used up.

The result, for many households, is less electricity purchased from the grid and less solar exported at low feed-in rates. How much less depends entirely on your specific usage.

## Time-of-Use Tariffs and Virtual Power Plants

Not every household is on a flat tariff, and this can change the store-vs-export decision.

With a time-of-use tariff, the peak electricity rate you pay (and sometimes the export rate you’re paid) varies through the day. If your peak usage rate is much higher in the evening, storing solar to use during that window can be worth more than a flat-rate comparison suggests. Some retailers also offer time-varying export tariffs that pay more for solar exported during high-demand periods, which can make exporting more competitive at specific times of day.

A virtual power plant (VPP) is another factor. Joining a VPP program means your battery can, at times, export stored energy back to the grid during high-demand events in exchange for a payment or credit, coordinated by the VPP operator. This can improve the financial case for a battery beyond straightforward self-consumption, though VPP terms, eligibility and payments vary by provider and battery brand. Ask your retailer or our team whether a VPP program is available and suitable for your battery model.

## What Might a Battery Change for a NSW Household?

This varies significantly by household size, usage pattern and battery capacity. The scenario below is illustrative only and not a projection of your own savings.

**Illustrative household profile**

4 people, roughly 20 kWh average daily solar production, roughly 25 kWh average daily consumption, with around 10 kWh currently exported per day at a feed-in rate of around 5-6 cents.

**Without a battery:** Roughly 10 kWh self-consumed during the day. Around 10 kWh exported, earning a modest feed-in credit. The remaining evening usage, roughly 15 kWh, is bought from the grid at 30-40 cents per kWh.

**With a battery (illustrative only):** A similar 10 kWh self-consumed during the day. Surplus solar charges the battery instead of being exported, subject to reserve settings and round-trip efficiency losses of roughly 3-5%. In the evening, the battery discharges to cover a share of usage, reducing but not necessarily eliminating grid purchases, since the battery may not charge fully every day depending on weather and consumption patterns.

The gap between the two scenarios can be meaningful over a year, but the actual number depends entirely on your export volume, tariff, battery size and usage pattern. *Illustrative only, actual results vary.*

## How RESINC Sizes a Battery for Your Home

At RESINC, we assess a household’s actual usage rather than sizing a battery off a generic rule of thumb. Where possible, we look at 6-12 months of real usage data from your bills or smart meter, covering seasonal variation across summer and winter, to understand your genuine evening consumption and export pattern.

From there, we recommend a battery size and brand, whether that’s Sungrow SBR or SBH, Anker SOLIX, FranklinWH or Sigenergy SigenStor, that actually matches how your household uses power, rather than the largest unit we can sell you.

## A Recent Comparison – What It Looked Like

**Anonymised RESINC customer, Newcastle NSW**

A household with an existing solar system and a low feed-in tariff rate asked us to review whether a battery was worth adding. Using around 8 months of billing data, we found meaningful daytime export and a consistent evening usage pattern, home from around 5pm with dinner, heating and appliance use through the evening.

Based on that usage, we recommended a mid-sized Sungrow SBR system sized to their evening draw rather than their total export volume, since oversizing would have meant paying for capacity they wouldn’t reliably use. This example illustrates our sizing approach rather than a guaranteed saving, since results depend on each household’s usage. *Illustrative only, actual results vary.*

## Does the Federal Battery Rebate Tip the Balance?

For many Australian homeowners, the Cheaper Home Batteries Program can make battery storage more affordable.

The program uses Small-scale Technology Certificates (STCs) to provide around a 30% upfront discount on eligible battery installations, with the available rebate depending on battery capacity and applicable STC factors.

The rebate can apply to batteries added to existing solar systems as well as eligible new installations. RESINC manages the STC process and applies the eligible discount directly to your invoice.

The next significant rebate reduction is scheduled for 31 December 2026.

Rebate values change every 6 months. Verify current figures with our team before making a final decision.

**Read More:** For the latest rebate amounts and eligibility rules, see our [**solar battery rebate and energy savings**](https://resinc.com.au/solar-battery-rebate-and-energy-savings/) page.

## When Battery Storage May Not Be the Better Choice

To be fair about this, a battery doesn’t stack up equally well for every household.

- Low evening electricity use. If your household draws very little power at night, a battery won’t discharge much, and the value of stored energy drops accordingly.
- Limited daytime surplus. If your existing system is small and mostly covers your daytime use already, there may not be much extra to store.
- A favourable tariff structure. Some time-varying export tariffs pay more for solar exported during specific windows, which narrows the gap a battery would otherwise close.
- Significant shading or panel underperformance. If your system isn’t generating well to begin with, adding storage compounds an existing problem rather than solving it.
- High upgrade costs. If your switchboard or inverter needs substantial work before a battery can be added, that cost needs to be weighed against the ongoing savings.

We’d rather walk you through these factors honestly than assume a battery is automatically the right call for your home.

## Export-Only Solar vs Solar With Battery

| **Factor** | **Export-Only Solar** | **Solar With Battery** | **Suitable Profile** | **Key Benefits** | **Limitations** |
|---|---|---|---|---|---|
| Feed-in tariff exposure | Full exposure to low export rates | Reduced, since more solar is self-consumed | High daytime export households | Less power sold at low rates | Battery cost, round-trip losses |
| Evening power source | Grid, at full purchase rate | Battery first, grid as backup | Households with evening usage | Lower grid purchases at peak rates | Battery may not fully charge every day |
| Blackout resilience | None (system shuts down without grid) | Possible, depending on setup | Blackout-prone areas | Backup power where changeover switch fitted | Not automatic on every install |
| Upfront cost | Lower | Higher, offset by potential rebate | Budget-conscious, rebate-eligible households | Rebate may reduce cost by around 30% | Larger initial outlay |
| Best suited to | Low evening use, favourable export tariff | High evening use, high daytime export | Varies by household | n/a | n/a |

*Illustrative only, actual results vary.*

## Should You Export Your Solar or Store It?

The maths on NSW feed-in tariffs is straightforward on the surface: you’re often selling surplus solar at 5-8 cents and buying it back at 30-40 cents. That’s a meaningful gap, and for a lot of households, a battery closes a good part of it.

But every home is different. Your export data, tariff structure, evening usage and existing inverter setup all shape the real numbers for your situation, and no generic comparison can substitute for looking at your own bills.

## FAQs

### What is the current feed-in tariff rate in NSW?

NSW feed-in tariff rates are often around 5-8 cents per kWh with major retailers, though there’s no government-set minimum in NSW so rates vary by provider and plan. Some retailers offer time-varying export tariffs that pay more during high-demand periods. Check your current bill or compare offers at energymadeeasy.gov.au. Tariff rates change frequently.

### Is solar worth it without a battery in NSW?

Yes, solar without a battery still reduces electricity bills by powering your home during the day. Without a battery, any solar your home doesn’t use in real time gets exported at a feed-in tariff rate that’s typically well below the grid purchase rate. Whether adding a battery makes financial sense depends on your export volume, evening usage and tariff structure, not a blanket rule.

### How much solar power does the average NSW home export?

This varies widely based on system size, household size and usage pattern. Households where most occupants are out during the day tend to export more. Reviewing your own electricity bill’s export data gives the most accurate picture for your situation.

### Does RESINC help NSW households with battery storage for existing solar?

Yes. Adding battery storage to existing solar is a common service for our NSW team. We assess your current system, confirm compatibility, size the battery from real usage data, and handle the full installation including rebate processing where applicable. Get a free [residential solar battery rebates nsw](https://resinc.com.au/residential-solar-systems/) systems assessment to see your options, or read more about [solar panels Newcastle](https://resinc.com.au/solar-installation-services-newcastle/).

### Which battery works best for maximising self-consumption in NSW?

The right battery depends on your daily export volume and household usage pattern. Sungrow’s modular SBR and SBH series suit varying household sizes. Anker SOLIX offers backup capability alongside self-consumption benefits. FranklinWH and Sigenergy SigenStor suit households wanting strong backup and broad inverter compatibility. We recommend based on your actual data. See [Sungrow solar battery systems](https://resinc.com.au/sungrowsolarbatterysystems/) and [Anker SOLIX batteries](https://resinc.com.au/anker/) for product details.

### Will battery storage still be worth it as feed-in tariff rates change?

Battery value is largely driven by the gap between the grid purchase rate and the feed-in tariff rate. As long as buying electricity from the grid costs more than selling solar back, batteries deliver value by increasing self-consumption. If grid purchase rates continue to rise, that generally makes battery storage more valuable over time, though this isn’t guaranteed and depends on future tariff movements.
