10kW Solar System with Battery Price in Australia: A Smart Investment for Your Energy Future

As energy costs continue to rise and sustainability becomes a top priority for Australian households and businesses, many are turning to solar energy as a smart, long-term solution. One of the most popular configurations is the 10kW solar system with battery, offering enough power for medium to large homes and even small commercial setups. But what is the price of a 10kW solar system with battery in Australia? And is it worth the investment?

In this guide, we’ll dive into everything you need to know about a 10kW solar and battery system — from costs, components, and government incentives to return on investment and environmental impact.

What Is a 10kW Solar System with Battery?

A 10kW solar system typically consists of around 24 to 27 solar panels (depending on the wattage of each panel), a 10kW inverter, and a battery storage unit ranging from 10kWh to 20kWh capacity. This setup is ideal for:

• Larger residential homes

• Households with high energy consumption (e.g., electric vehicles, pools, home offices)

• Small businesses operating during the day and into the evening

• Property owners looking to go off-grid or reduce reliance on the grid

When paired with a battery storage system, your solar setup can store excess energy generated during the day and use it at night or during blackouts. This 10kW solar battery package in Australia gives you greater energy independence, cost savings, and long-term peace of mind.

How Much Does a 10kW Solar System with Battery Cost in Australia?

✅ Average Price Range (2024)

The cost of a 10kW solar system with battery in Australia can vary based on location, brand, installation complexity, and battery size. On average, here’s what you can expect:

System Type: Price (after STC rebate)

10kW solar only: $8,000 — $12,000

10kW solar + 10kWh battery: $15,000 — $20,000

10kW solar + 13.5kWh Tesla Powerwall: $21,000 — $24,000

10kW hybrid solar system: $17,000 — $23,000

💡 Note: Prices can be lower with rebates, offers, and when bundled with an energy retailer deal.

What Influences the Price of a 10kW Solar Battery System?

1. Battery Brand & Capacity

   
   

   Premium batteries like Tesla Powerwall, Sonnen, or LG Chem cost more but offer higher performance and longer warranties.

2. Panel & Inverter Brand

   
   

   Tier 1 solar panels (e.g., SunPower, Jinko, Trina) and reliable inverters (e.g., Fronius, Sungrow, Huawei) affect overall system quality and price.

3. Installation Complexity

   
   

   Roof type, tilt, accessibility, and switchboard upgrades can influence installation costs.

4. Hybrid System vs Standard

   
   

   A hybrid solar system (10kW) includes an inverter capable of handling battery integration, sometimes increasing costs but simplifying future upgrades.

5. Location

   
   

   Costs vary slightly between states due to labour, transport, and market competition.

Government Rebates and Incentives

To make solar more affordable, the Australian Government offers several incentives:

🟢 Small-scale Technology Certificates (STCs)

You can claim STC rebates for systems under 100kW. For a 10kW system, this can reduce your upfront cost by $3,000 to $4,000 depending on your location.

🟢 State-Specific Battery Rebates

Some states offer additional incentives for battery storage systems:

• Victoria Solar Homes Program — Battery rebates up to $2,950

• South Australia Home Battery Scheme — Up to $2,000

• Queensland Battery Booster Program — Up to $4,000

Check your eligibility on official government websites or consult with trusted solar providers like Ads Solar.

How Much Can You Save with a 10kW Solar System + Battery?

A well-installed 10kW solar battery system in Australia can generate around 35–45 kWh of energy per day depending on your location and sun exposure.

If you’re paying 30c per kWh from the grid, that’s $10 to $13.50 in daily savings, or over $3,500–$5,000 annually — even more if you use battery power during peak tariff times.

Return on Investment (ROI)

Scenario: ROI Timeline

10kW solar system only: 3–5 years

10kW solar with battery: 5–8 years

🌞 You can further accelerate your ROI by using smart appliances, monitoring usage via apps, and optimising feed-in tariffs.
