Solar and Battery Package Price Australia 2026: What You'll Actually Pay

A solar and battery package price in Australia ranges from about $8,000 to $25,000 fully installed as of May 2026. That is before the federal battery rebate, which knocks roughly 30% off the battery component. After the rebate, most households pay $5,000 to $17,000 for a complete system. The most popular combination, a 6.6kW solar system with a 10kWh battery, lands between $10,500 and $14,000 pre-rebate, or roughly $7,000 to $10,500 after the federal Cheaper Home Batteries discount.

Those numbers might still sound like a lot. They are. But consider what you are replacing: grid electricity at an average of 39 cents per kilowatt-hour, rising every year, while your solar panels export surplus power for just 3 to 10 cents. A battery closes that gap by storing cheap daytime solar for your evening use instead. The financial case has shifted over the past twelve months, driven by falling battery prices, rising grid rates, and the federal rebate that launched in July 2025.

This guide breaks down every cost involved, shows you exactly how the rebate applies, and helps you figure out whether bundling solar and a battery together is the right move for your home.

Solar and Battery Package Prices by System Size

All prices below are fully installed and include both the solar STC rebate (applied to panels) and installation labour. Battery prices are pre-rebate, so you can see the full picture before and after government support.

A package deal is a solar system plus battery purchased and installed together in a single visit. That distinction matters because it affects your total cost, as covered in the next section.

System Size	Battery Size	Package Price (installed, pre-battery rebate)	Battery Rebate (~$372/kWh)	Post-Rebate Package Price
5kW solar	10kWh	$8,000–$12,500	~$3,720	$4,300–$8,800
6.6kW solar	10kWh	$10,500–$14,000	~$3,720	$6,800–$10,300
6.6kW solar	13.5kWh	$12,000–$17,000	~$5,022	$7,000–$12,000
8kW solar	10kWh	$12,000–$15,500	~$3,720	$8,300–$11,800
10kW solar	13.5kWh	$14,500–$20,000	~$5,022	$9,500–$15,000
10kW solar	16kWh	$15,500–$22,000	~$5,654	$9,800–$16,300
13kW solar	16kWh	$17,500–$25,000	~$5,654	$11,800–$19,300

Prices are as of May 2026 and reflect the range across budget, mid-range, and premium component choices from CEC-accredited installers. Solar prices already have STCs applied. From 1 May 2026, the federal rebate moved to a tiered structure. The first 14kWh of capacity still receives the full $372/kWh rate. Capacity between 14 and 28kWh receives 60% ($223/kWh), and capacity between 28 and 50kWh receives 15% (~$56/kWh). For standard 10 to 13kWh batteries, the rebate is identical to the pre-May flat rate. The tiering only reduces rebate value for batteries larger than 14kWh, and the difference on a 16kWh unit is roughly $300.

How the Federal Battery Rebate Changes the Maths

The Cheaper Home Batteries Program, administered by the Department of Climate Change, Energy, the Environment and Water, is the single biggest factor in making a solar and battery package financially viable for most households.

Here is how it works. The rebate is applied at point of sale by your CEC-accredited installer. You do not need to apply separately or claim anything back. Your quote shows the discounted price directly. Every battery listed on the Gridly home batteries comparison page qualifies.

The rate:

• ~$372 per usable kWh for the first 14kWh (unchanged from 2025)
• Up to 50kWh per household
• Maximum rebate of ~$18,500

From 1 May 2026, the structure is tiered:

• 0 to 14kWh: ~$372/kWh (full rate)
• 14 to 28kWh: ~$223/kWh (60% of full rate)
• 28 to 50kWh: ~$56/kWh (15% of full rate)

For standard residential batteries in the 10 to 14kWh range, the rebate is identical to the pre-May flat rate. The tiering only affects capacity above 14kWh. If you are considering a 16kWh battery, the first 14kWh gets the full $372 rate and the remaining 2kWh gets ~$223/kWh. The difference on a 16kWh unit is roughly $300 less rebate compared to the old flat rate across all capacity.

454,753 home batteries had been installed across Australia by end-2025. That number is climbing fast, and the rebate is the primary driver.

Keep in mind that the solar panels in your package receive a separate incentive through Small-scale Technology Certificates (STCs). STCs are a federal mechanism that discounts solar panels at the point of sale, typically worth $1,800 to $3,600 depending on system size. Both incentives apply simultaneously to a bundled package, which is one reason packages have become so popular.

Is a Package Cheaper Than Buying Solar and Battery Separately?

Yes. Buying solar panels and a battery together saves $1,000 to $2,000 compared to purchasing each separately at different times.

The savings come from shared labour. When an electrician installs solar panels, they already upgrade your switchboard, run new wiring, and configure your meter connection. Adding a battery to that same visit means the electrician is already on site, the switchboard is already open, and the electrical configuration is already underway. A separate battery retrofit later means paying for a second site visit, a second round of electrical work, and potentially a second switchboard modification.

Here is a rough cost comparison for a 6.6kW solar system with a 10kWh battery:

Bought separately:

• 6.6kW solar system installed: $5,000–$6,500 (mid-range, after STCs)
• 10kWh battery supply: $4,500–$5,500
• Battery installation (retrofit): $2,000–$3,500
• Total: $11,500–$15,500

Bought as a package:

• 6.6kW solar + 10kWh battery installed together: $10,500–$14,000
• Saving: $1,000–$1,500

The saving is real but not dramatic. If you already have solar and want to add a battery, do not feel pressured to rip out your existing system just to get the package discount. A battery retrofit is straightforward for any competent installer and the federal rebate applies regardless of whether you buy a package or add storage later.

One scenario where buying separately makes more sense: if your solar system is only two to three years old and performing well, there is no benefit to replacing it. Add a battery when it suits your budget. The rebate is not going away immediately, though the tiered structure from May 2026 does reduce the per-kWh value slightly for larger systems.

What Affects Your Solar and Battery Package Price

Several factors swing the total cost by thousands of dollars. Understanding them helps you evaluate quotes and spot where your money is well spent.

Battery brand and capacity

Battery choice is the biggest variable. Supply prices range from $4,500 for a 10kWh Growatt APX HV to $9,000 for a 13.5kWh Tesla Powerwall 3. Per-kWh pricing varies even more. The GoodWe ESA 16kWh at $331/kWh is the current value leader, while the Enphase IQ Battery 5P at $1,640/kWh sits at the other end. Brand recognition, software ecosystem, and warranty terms all contribute to these differences.

Solar panel and inverter quality

Budget panels with a basic string inverter sit at the low end of the solar cost range. Premium panels from REC or SunPower paired with Enphase micro-inverters push toward the top. For most homes, a quality mid-range setup using Trina or Jinko panels with a Fronius or GoodWe hybrid inverter offers the best balance of performance, warranty coverage, and cost.

Hybrid inverters deserve a mention. A hybrid inverter is a single unit that manages both your solar panels and your battery. If you are buying a package, a hybrid inverter avoids the need for a separate battery inverter, reducing both cost and complexity. Most modern package installations use a hybrid inverter by default.

Roof complexity and access

Single-storey homes with simple tin roofs are the cheapest to install on. Multi-storey homes, tile roofs, and heritage buildings add labour time and scaffolding costs. Expect an extra $500 to $1,500 for a complex roof installation compared to a straightforward one.

Your location

Installer competition varies by region. Metro areas in Sydney, Melbourne, Brisbane, and Perth have the most installers competing for business, which keeps prices in check. Regional and remote areas attract higher costs due to travel and limited competition. Darwin and far north Queensland can run well above the metro ranges.

Switchboard and electrical upgrades

Older homes sometimes need a switchboard upgrade to safely accommodate both a solar system and a battery. If your switchboard is an older model without adequate circuit breakers or space, this can add $500 to $1,500 to the installation. Your installer should identify this during the site assessment before quoting.

Best Value Solar and Battery Combinations in 2026

Based on current pricing as of May 2026, these combinations offer the best balance of cost, quality, and performance for different household sizes. All prices are installed package estimates before the battery rebate.

Budget-conscious (small home, low usage):

• 5kW solar (Trina or Jinko panels, GoodWe hybrid inverter)
• GoodWe ESA 16kWh battery ($331/kWh, best value per kWh)
• Package estimate: $10,000–$13,000
• Post-rebate: ~$4,300–$7,300

Despite the “budget” label, the GoodWe ESA 16kWh is a genuinely good battery. At $331 per kWh, it dramatically undercuts the field. Pairing it with a GoodWe hybrid inverter keeps compatibility simple and installation costs low.

Mid-range (average home, 6.6kW):

• 6.6kW solar (Jinko or LONGi panels, Fronius or GoodWe hybrid inverter)
• BYD Battery-Box HVS 10.2 ($539/kWh) or Growatt APX HV 10.0 ($440/kWh)
• Package estimate: $10,500–$14,500
• Post-rebate: ~$7,000–$11,000

BYD is the most installed battery brand in Australia for a reason. Strong dealer network, solid warranty support, and proven reliability. The Growatt APX is cheaper per kWh and suits tighter budgets without sacrificing much on quality.

High usage (large home, EV, pool):

• 10kW solar (quality mid-range panels, Sungrow or Fronius hybrid inverter)
• Sungrow SBR096 HV 9.6kWh ($677/kWh) or Tesla Powerwall 3 13.5kWh ($667/kWh)
• Package estimate: $14,500–$21,000
• Post-rebate: ~$10,000–$16,000

Sungrow and Tesla both command a premium but deliver mature software, strong monitoring apps, and broad installer familiarity. The Powerwall 3 includes an integrated inverter, which can simplify the installation and reduce total cost in some configurations. If brand and ecosystem matter to you, these are the picks.

Maximum storage:

• 13kW solar (premium panels, three-phase inverter)
• BYD Battery-Box HVM 16.6 ($512/kWh) or GoodWe ESA 16kWh ($331/kWh)
• Package estimate: $17,500–$25,000
• Post-rebate: ~$11,800–$19,300

At this size, you are generating and storing enough to cover almost all of your household electricity needs. These systems suit large homes with high consumption, electric vehicles, and pool pumps. The tiered rebate structure means your per-kWh rebate is slightly lower above 14kWh, but the absolute discount is still substantial.

Payback Period for Solar and Battery Packages

Payback depends on two separate calculations running in parallel: the solar payback and the battery payback.

Solar payback: 3.5 to 5 years

Solar panels pay for themselves relatively quickly. A 6.6kW system generating 26 to 28kWh per day saves $1,200 to $2,000 annually through self-consumption and feed-in credits. At an installed cost of $5,000 to $6,500, payback lands between 3 and 5 years. 4.3 million Australian homes already have rooftop solar, and the financial case is well established.

Battery payback: 5 to 10 years post-rebate

Batteries take longer. A 10kWh battery cycled daily stores roughly 3,650kWh per year. At a self-consumption value of 30 to 35 cents per kWh (the grid rate you avoid minus the feed-in rate you give up), that is $1,000 to $1,300 per year in savings. Post-rebate installed costs for a 10kWh battery sit around $4,500 to $8,500 depending on brand and installation complexity. Payback: 4 to 8 years for most configurations.

Combined payback: 7 to 10 years

The combined system cost is higher, but the solar component starts generating returns from day one. By year 4, your panels have likely paid for themselves and every kWh they produce is pure return. By year 7 to 10, the battery has also paid itself off. From that point, your electricity costs drop close to zero for the remaining 15 to 20 years of system life.

Factors that shorten payback:

• High evening electricity usage (more stored kWh consumed)
• Expensive grid tariffs (SA, parts of NSW at 40+ cents/kWh)
• VPP participation ($130 to $450 extra income per year)
• Stacking the federal rebate with a state rebate in WA or NSW

Factors that lengthen payback:

• Low evening usage (small household, mostly home during the day)
• Cheap grid electricity (some QLD plans under 28 cents/kWh)
• Oversized battery for your actual consumption pattern

Frequently Asked Questions

How much does a solar and battery package cost in Australia in 2026?

A solar and battery package costs $8,000 to $25,000 installed before the federal battery rebate. After the Cheaper Home Batteries rebate, expect $5,000 to $17,000 depending on system size and battery choice. The most common 6.6kW solar plus 10kWh battery bundle runs $10,500 to $14,000 pre-rebate.

Is it cheaper to buy solar and a battery together?

Yes, buying as a package typically saves $1,000 to $2,000 over purchasing separately. You share one electrician visit, one switchboard upgrade, and one set of wiring. The installer bundles labour more efficiently. The savings are real but modest relative to total cost.

What is the payback period for a solar and battery package?

Combined payback is 7 to 10 years for most Australian households. The solar component pays for itself in 3.5 to 5 years, while the battery portion takes 5 to 10 years post-rebate. Homes with high evening usage and expensive grid electricity see the shortest payback.

Does the federal battery rebate apply to solar and battery packages?

Yes. The Cheaper Home Batteries Program applies to the battery component of any package installed by a CEC-accredited installer. The rebate is roughly $372 per usable kWh, applied as a point-of-sale discount. Solar panels receive a separate STC rebate. Both apply simultaneously.

What size solar and battery package do I need for an average home?

Most Australian homes suit a 6.6kW solar system paired with a 10 to 13kWh battery. That combination covers typical daytime generation and stores enough surplus for evening use. Larger homes with pools, EVs, or high air conditioning loads should consider 10kW solar with 15kWh or more storage.
