If you've started looking at solar lately, you've probably noticed something: almost every quote now comes with a battery. Thanks to the federal battery rebate and rising evening power prices, solar and battery bundles have become the most talked-about home energy upgrade in Australia. But what does a solar and battery package price actually look like in 2026, and how do you know if a quote is fair?
This guide breaks down typical package prices by system size, explains how the rebates work right now, shows what affects the final price and gives you a simple checklist for comparing quotes. No sales pitch, just the numbers and what they mean.
Solar and battery package price in 2026: the quick answer
For a typical Australian home, a solar and battery package usually costs somewhere between $10,000 and $25,000 after the federal rebates, depending mostly on the size of the solar system and the battery.
Here are typical installed prices, after federal rebates, based on recent October 2026 market data:
| Package | Good for | Typical price after federal rebates |
|---|---|---|
| 6.6kW solar + 5kWh battery | Small households, lower evening use | $10,000 to $14,000 |
| 6.6kW solar + 10kWh battery | Typical 3-bedroom family home | $12,000 to $19,000 |
| 10kW solar + 13.5kWh battery | Larger homes, higher evening use | $17,000 to $25,000 |
| 10kW solar + 16kWh battery | Big families, pool or EV | $19,000 to $25,000 |
| 13kW solar + 20kWh battery | Large homes, ducted air con, EV | $24,000 to $31,000 |
Some states offer extra rebates on top, which can bring these prices down further. Prices also vary between cities, installers and brands, so treat these as a guide rather than a fixed price list.
How the battery rebate works right now
The federal Cheaper Home Batteries Program gives a discount on eligible home batteries, usually applied directly on your quote by the installer. It works through small-scale technology certificates (STCs), the same system that has discounted rooftop solar for years.
Here's what's important to know in late 2026:
- The discount depends on battery size. Since 1 May 2026, the first 14kWh of a battery gets the full rebate rate, capacity from 14 to 28kWh gets 60% of it, and capacity from 28 to 50kWh gets just 15%.
- The value is roughly $272 per kWh for the first 14kWh for batteries installed up to the end of 2026, before any admin fees. In practice, that means around $2,500 to $2,700 off a typical 10kWh battery.
- It drops every six months. The rate is scheduled to step down from January 2027 and keep falling until the program winds down around 2030.
- The installation date counts, not the date you sign the contract.
To be eligible, the battery generally needs to be on the Clean Energy Council's approved list, between 5kWh and 100kWh in size, installed alongside rooftop solar by an accredited installer, and capable of joining a virtual power plant (you don't have to actually join one). Rules can change, so check the latest details with the Clean Energy Regulator before you commit.
Solar panels have their own separate STC rebate, which is also built into most quotes and also reduces each year.
What affects the price of a solar and battery package?
1. Solar system size
A 6.6kW system suits many average homes, while 10kW or 13kW systems suit larger households or homes with electric cars and ducted air con. Bigger systems cost more upfront but often work out cheaper per kW.
2. Battery size
Battery capacity is measured in kilowatt-hours (kWh). A 10kWh battery stores enough to run a typical home's evening lights, fridge, TV and cooking for several hours. Because of the tiered rebate, the best value is usually in batteries up to about 14kWh.
3. Brand and quality
Premium brands cost more but often come with longer warranties, better apps and stronger local support. Cheaper batteries can be fine, but check the warranty terms and whether the company has an Australian office.
4. Type of inverter
A hybrid inverter can run both solar panels and a battery, which often makes a combined package cheaper than adding a battery later. Our solar inverter guide explains the different types.
5. Installation complexity
Tile vs tin roofs, two-storey homes, switchboard upgrades and long cable runs can all add to the cost. Blackout backup also usually costs extra.
6. Where you live
Prices, sunshine and state rebates vary by location, so the same package can cost a different amount in Perth than in Melbourne.
Is a solar and battery package worth it?
It depends on how and when you use electricity. Batteries make the most financial sense if:
- You use a lot of power in the evening, after the sun goes down
- Your solar feed-in tariff is low, so exporting power earns you very little
- You're on a time-of-use plan with expensive evening peak rates
- You want backup power during blackouts
- You plan to stay in your home for many years
For a typical package, payback is often estimated at around 7 to 12 years, though it can be shorter for high evening users and longer for small households. Most quality batteries come with a 10-year warranty, so the closer your payback is to the lower end, the better the deal.
If you're mostly home during the day, solar on its own may give you better value, and you can always add a battery later. Before you spend big, it's also worth tackling the cheap wins first. Our guide on how to lower your power bill covers simple changes that cut costs straight away.
How to compare solar and battery quotes
Getting at least three quotes is the best way to make sure you're paying a fair price. When they arrive, check:
- The exact panel, inverter and battery brands and models, not just "premium panels".
- Usable battery capacity in kWh, since some quotes list a bigger "total" figure.
- Whether the price already includes the rebates, and how much each rebate is worth.
- Warranties on panels, inverter, battery and the installation itself.
- Whether blackout backup is included, and for which circuits.
- Any extra costs such as switchboard upgrades, metering or difficult roof access.
- That the installer is accredited and the products are on the approved list.
Red flags to watch for
- High-pressure sales or "today only" pricing
- Door-knockers or cold callers pushing a quick sign-up
- Claims of a "free" battery or system with no clear costs
- Vague quotes without brand names or model numbers
- Promises that your power bill will drop to zero
A good installer will look at your actual electricity usage, ideally from your bill or smart meter data, before recommending a size.
Frequently asked questions
How much is a 6.6kW solar system with a 10kWh battery in Australia?
In 2026, a 6.6kW solar system with a 10kWh battery typically costs around $12,000 to $19,000 after federal rebates. The final price depends on brands, location, roof type and any state rebates.
How much does the battery rebate save?
For batteries installed by the end of 2026, the federal rebate is worth roughly $272 per kWh for the first 14kWh, before admin fees. A 10kWh battery typically gets around $2,500 to $2,700 off. The rate drops every six months from 2027.
Is it cheaper to buy solar and a battery together?
Often, yes. Installing both at once usually means one installation visit and a single hybrid inverter, which can save money compared with adding a battery separately later.
How long do home batteries last?
Most home batteries come with a 10-year warranty and are expected to last around 10 to 15 years, gradually losing some storage capacity over time.
The bottom line
In 2026, most Australian households can expect to pay roughly $10,000 to $25,000 for a solar and battery package after rebates, with a 6.6kW system and 10kWh battery being the most common choice. The battery rebate is at its most generous right now and will step down from January 2027, so timing matters if you've already decided a battery suits you.
Just don't rush. Check your evening power use, get at least three detailed quotes, and compare them line by line. The right package is the one that matches how your household actually uses electricity.
