10kW solar system price Brisbane 2025
In Brisbane, the cost for a quality 10kW solar system (panels and inverter only) typically ranges from $8,000 to $13,000 after the standard solar panel rebate (STCs) has been applied.
When you add a 10kWh battery, the total installed price in Brisbane before the new battery rebate is generally between $18,000 and $25,000. After the federal battery rebate is applied, Brisbane homeowners can expect the final price for a complete 10kW solar and 10kWh battery system to be in the $14,500 to $21,000 range.
Understanding costs in regional Queensland
While Brisbane often has the most competitive pricing due to a higher volume of installers, regional Queensland is also well-serviced. However, you might see slightly higher prices in regional areas due to travel and freight costs for equipment.

The federal government’s Cheaper Home Batteries Program
This is the big news for 2025. Starting July 1, the federal government’s Cheaper Home Batteries Program makes battery storage accessible to many more households.
Here’s what you need to know:
-
What is it? An upfront discount on the cost of a new battery system.
-
How much is the rebate? It’s expected to be around 30% of the system cost, translating to approximately $350-$370 per kWh of battery capacity. For a 10kWh battery, this is a saving of about $3,500.
-
Who is eligible? All homeowners and small businesses installing an approved, VPP-capable battery with a new or existing solar system.
-
How do you get it? Your SAA-accredited installer applies the discount for you at the point of sale. You don’t have to claim it back yourself; the discount comes directly off your invoice.
How your solar installer applies the rebates in QLD
Understanding the rebates can be confusing, but the process is designed to be simple for the homeowner.
-
STC Rebate (for Solar Panels): This is the standard “solar rebate.” Small-scale Technology Certificates (STCs) are created based on your system’s size and location. Your installer claims these on your behalf and gives you an upfront discount on your total system cost. This is why you see an “after rebate” price on quotes.
-
Federal Battery Rebate: This new rebate works the same way. The installer will calculate the rebate based on the battery’s size and deduct it from your final price. You just pay the remaining balance.
A simple step-by-step process for the Queensland federal battery rebate
From your perspective, the process is seamless and managed by your installer.
-
Step 1: Get Quotes: Contact several reputable, Solar Accreditation Australia (SAA) accredited installers for quotes on a solar and battery system.
-
Step 2: Confirm Rebate on Quote: The installer will provide a quote that clearly shows the full system price, the STC rebate for the panels, and the new federal battery rebate as separate line items, resulting in a final, lower price for you to pay.
-
Step 3: Sign the Agreement: Once you accept a quote, you’ll sign some paperwork that allows the installer to claim the rebates on your behalf.
-
Step 4: Installation: The accredited team installs your system.
-
Step 5: Pay the Final Invoice: You pay the final amount shown on the quote, which already has the rebate savings applied. Your installer handles all the complex paperwork.
Case Study: A Family in Toowoomba The O’Connor family were struggling with quarterly power bills often exceeding $700 due to their pool and running the air-con in summer. They installed a 10kW system with Jinko panels and a 10.1kWh Alpha ESS battery for a total cost of $21,500. After the federal battery rebate of roughly $3,700, their final cost was $17,800. Their annual savings are now projected to be over $2,800, putting them on track for a payback period of just over 6 years. Their last electricity bill was only for the daily grid connection fee.
Comparing top battery brands: Alpha ESS vs. BYD in QLD
Two of the most popular and reliable battery brands I see in Queensland are Alpha ESS and BYD. They both offer fantastic performance but have slightly different strengths.
| Feature | Alpha ESS SMILE-G3 (~10.1kWh) | BYD Battery-Box Premium HVM (~11.04kWh) |
|---|---|---|
| Estimated Installed Cost | $9,000 – $11,000 | $10,000 – $12,500 |
| System Type | All-in-one (includes hybrid inverter) | Modular battery (requires a compatible hybrid inverter) |
| Best For | New solar and battery installations (value) | Adding a battery to an existing system or those wanting flexibility with inverter choice. |
| Warranty (10 years) | 10,000 cycles | ~4,000 cycles (or total energy throughput) |
A common mistake I see homeowners make is focusing only on the upfront price. The Alpha ESS often looks cheaper because it includes the inverter, making it a fantastic value package for a brand-new system. The BYD offers more flexibility and is a rock-solid performer, making it a top choice for those who already have a compatible hybrid inverter.
What about QLD’s solar feed-in tariffs in 2025?
Solar feed-in tariffs (the amount your retailer pays you for exporting excess solar energy) are continuing to decrease. For 2025-2026, the regulated tariff in regional Queensland has dropped significantly. In South East Queensland, rates vary by retailer but the trend is the same.
This is precisely why battery storage now makes so much sense. Earning 8-12c/kWh for your valuable solar energy only to buy it back in the evening for 30-40c/kWh is not a great deal. With a battery, you store that energy for free and use it at night, maximising your savings and insulating yourself from low feed-in tariffs and high electricity prices.
Finding the best local solar installers in Queensland
Choosing the right installer is the most important decision you’ll make. A great installer ensures your system performs safely and efficiently for decades. I always recommend getting at least three quotes from local, SAA-accredited professionals with strong customer reviews.
Here are some of the top-rated installers I’ve come across in my research for various Queensland regions:
-
Toowoomba: Look for companies like Electrical Sensations and Solahart Darling Downs, which have strong local reviews and awards.
-
Sunshine Coast: Installers like Wholesale Solar and Batteries are well-regarded for their in-house teams and long-term experience.
-
Gold Coast: Companies such as Solar Masters and Gold Coast Solar Power Solutions have a long history of positive customer feedback.
-
Mackay: Mission Green Solar and Solahart Mackay are frequently mentioned by happy local customers.
-
Rockhampton: Swann’s Solar & Electrical and EcoSmart Solar are two highly-rated local installers with a strong presence in Central Queensland.
-
Hervey Bay & Bundaberg: In the Wide Bay region, look for established local companies like Bundaberg Solar, Fraser Coast Solar, and Wide Bay Solar who receive positive customer testimonials.
