Average Battery Costs: Before and After the Rebate
Understanding the real cost of battery storage is essential for working out whether it’s worth the money for your household.
Battery System Costs Before the Rebate
Battery system costs vary a lot based on how much they store, which brand you choose, and how hard they are to install:
Small Systems (5-8kWh):
- Budget options: $8,000-$12,000 installed
- Premium brands: $12,000-$16,000 installed
Medium Systems (10-15kWh):
- Budget options: $12,000-$18,000 installed
- Premium brands: $16,000-$24,000 installed
Large Systems (20kWh+):
- Budget options: $20,000-$30,000 installed
- Premium brands: $28,000-$40,000 installed
kWh = kilowatt hours, which measures how much energy the battery can store. A 10kWh battery can store enough power to run a typical home for about 8-12 hours.
Specific Brand Pricing Examples
Tesla Powerwall Pricing: The Tesla Powerwall 2 costs between $13,500-$15,000, including full installation. Australian pricing for the Tesla Powerwall 3 starts at $11,900, which includes the 13.5 kWh battery and built-in inverter (the inverter converts the battery’s power to work in your home). This price doesn’t include the required Tesla Backup Gateway unit.
Market Average: Based on installer pricing, the average installed cost of a Tesla Powerwall battery is $1,129 per usable kWh, putting it at the expensive end of the home battery market.
Costs After the Rebate
The rebate makes a big difference to how affordable the system is:
For $4,000 rebate recipients:
- $15,000 system becomes $11,000 (27% cheaper)
- $20,000 system becomes $16,000 (20% cheaper)
- $12,000 system becomes $8,000 (33% cheaper)
For $3,000 rebate recipients:
- $15,000 system becomes $12,000 (20% cheaper)
- $20,000 system becomes $17,000 (15% cheaper)
- $12,000 system becomes $9,000 (25% cheaper)
These price cuts make battery storage much more affordable and help you pay back your investment faster.
How Battery Size Affects Your Savings and Payback Time
Choosing the right battery size is crucial for getting the best savings and return on your money.
Understanding Battery Sizing Basics
Your battery size should match how much power you use in the evening and overnight, as this is when stored solar energy saves you the most money. Unlike solar panels, where bigger is often better, batteries need to be matched more carefully to how much power you actually use.
Small Batteries (5-8kWh): Targeted Savings
Best for:
- 1-3 person households with modest evening power use
- Homes with efficient appliances and LED lighting
- Properties already using most of their solar power during the day
Typical savings:
- $800-$1,200 each year in lower power bills
- Payback time: 8-12 years (6-9 years with rebate)
- Best value per kWh but limited total savings
Medium Batteries (10-15kWh): Balanced Approach
Best for:
- 3-5 person households with moderate evening use
- Homes with electric hot water systems or pool pumps
- Properties planning for future electric car charging
Typical savings:
- $1,200-$1,800 each year in lower power bills
- Payback time: 9-13 years (7-10 years with rebate)
- Good balance between cost and capability
Large Batteries (20kWh+): Maximum Independence
Best for:
- Large households with high energy use
- Properties with significant evening/night power use
- Homes wanting maximum independence from the power grid
Typical savings:
- $1,800-$2,500+ each year in lower power bills
- Payback time: 10-15 years (8-12 years with rebate)
- Highest total savings but longer payback times
What Affects Your Payback Calculations
Power bill structure: Time-of-use tariffs (where power costs more at peak times) with high evening peak rates make batteries much more worthwhile, potentially cutting payback times by 2-3 years.
When you use power: Households that use lots of power in the evening (6pm-10pm) get better returns than those who mainly use power during the day.
Solar system connection: Existing solar customers who don’t use much of their daytime solar power get the best benefits from adding a battery.
Future power price rises: Conservative estimates suggest 3-5% yearly increases, which makes battery economics even better over time.

Long-term Money Returns: How the Rebate Changes Everything
The Battery Booster rebate completely changes the investment equation for home battery storage, turning marginal investments into attractive long-term options.
Money Modelling Over 10+ Years
Without Rebate Scenario:
- Initial cost: $15,000 (typical 10kWh system)
- Yearly savings: $1,400
- Simple payback: 10.7 years
- 15-year total savings: $21,000
- Net benefit: $6,000
With $3,000 Rebate:
- Initial cost: $12,000
- Yearly savings: $1,400
- Simple payback: 8.6 years
- 15-year total savings: $21,000
- Net benefit: $9,000 (50% improvement)
With $4,000 Rebate:
- Initial cost: $11,000
- Yearly savings: $1,400
- Simple payback: 7.9 years
- 15-year total savings: $21,000
- Net benefit: $10,000 (67% improvement)
Things That Make Long-term Returns Even Better
Power Price Rises: Conservative estimates suggest 3-4% yearly increases in power prices. Over 15 years, this adds up to much higher savings than the initial calculations suggest.
Technology Improvements: While battery prices are falling, installation and grid connection costs stay stable. Early adopters with rebate support may get better value than future buyers.
Grid Independence Value: Beyond money returns, battery storage gives you energy security during blackouts and protection against future grid infrastructure charges.
Risk Factors to Consider
Technology Changes: Quick improvements in battery technology could make current systems look outdated within 5-10 years, though the rebate reducing your initial cost partly offsets this risk.
Rule Changes: Future changes to feed-in tariffs (payments for excess solar), grid connection charges, or power market structures could impact long-term returns.
System Reliability: Battery degradation (gradual loss of storage capacity) and potential replacement costs after 10-15 years should be factored into long-term financial planning.

FAQs – QLD Battery Rebate
How do I apply for the Queensland battery rebate?
Applications are processed through participating installers who handle the paperwork for you. You’ll need to provide proof of income, property ownership, and make sure your chosen battery and installer meet program requirements. The rebate is usually applied as a discount when you buy rather than a refund later.
Can I get the rebate if I already have solar panels?
Yes, the rebate is available whether you’re adding a battery to an existing solar system or installing solar and battery together. In fact, existing solar customers often see the best returns from battery storage as they can immediately start storing excess daytime power generation.
What happens if I move house after getting the rebate?
The rebate is tied to the property rather than you personally, so you can’t transfer it to a new property. However, the battery system usually adds value to your home and can be an attractive selling point for environmentally conscious buyers.
Are there any ongoing responsibilities after getting the rebate?
Beyond standard system maintenance and monitoring, there are no specific ongoing responsibilities. However, you should maintain your system properly to make sure it continues performing as expected and providing the anticipated energy savings.
Can I add more battery storage later if I get the rebate now?
Yes, though any future additions won’t be eligible for additional rebates under this program. Many modular battery systems allow for expansion, making it possible to start with a smaller system and grow storage as needed or budgets allow.
What happens if my battery system fails after a few years?
Quality battery systems come with comprehensive warranties usually covering 10 years or more. Choose systems from reputable manufacturers with strong Australian support networks to make sure warranty claims can be processed efficiently if needed.
How does the rebate affect my solar feed-in tariff payments?
The battery rebate doesn’t directly affect your feed-in tariff (payments for excess solar power), but battery storage will reduce how much excess solar energy you export to the grid. This usually improves your overall solar economics as stored energy used in the evening is worth 2-3 times more than exported energy.
Can I install the battery myself to save money?
No, the rebate program requires installation by Clean Energy Council licensed installers. This ensures safety, compliance with Australian standards, and proper system setup. DIY installation would void both the rebate and manufacturer warranties.
What size battery should I choose to maximise the rebate value?
The rebate amount isn’t based on battery size but on your household income. However, choosing the right size for your power usage patterns is crucial for maximising overall value. Most households find 10-15kWh systems provide the best balance of rebate value and long-term savings.
Is battery storage worth it without the rebate?
While the rebate significantly improves the economics, battery storage can still be worthwhile for households with appropriate power usage patterns, particularly those on time-of-use tariffs or in areas with frequent power outages. The decision should be based on your specific circumstances and financial goals.
