With electricity prices rising across Australia and the federal government’s new battery rebate program making solar battery storage more affordable than ever, homeowners on the Sunshine Coast are increasingly considering adding batteries to their solar panel installation in eumundi.
Whether you’re in Caloundra, Maroochydore, Eumundi, Montville, or Noosa Shire, understanding solar battery price differences can help you make the best investment for your home’s energy future.
Why Solar Battery Storage Matters for Sunshine Coast Homes
Solar battery storage system allows you to store excess energy generated by your solar panels during the day and use it during evening peak hours when electricity rates are highest. A standard residential solar system without a battery generally offsets around 30% to 50% of a household’s electricity usage. By adding a solar battery, this coverage can be increased to 80%, 90%, or even up to 100%, depending on your energy needs and system size.
For homeowners seeking batteries for solar panels in Eumundi and across the Sunshine Coast, the benefits extend beyond just financial savings. Solar battery systems provide backup power during outages, reduce your carbon footprint, and offer greater energy independence.
Current Solar Battery Price Landscape in Australia
Understanding solar battery cost is essential for making a smart and informed choice for your home energy system. On average, residential solar batteries range from $1,000 to $1,200 per kWh of installed capacity, with final prices varying based on the brand, system size, and location. This means a typical 10kw solar battery is priced between $10,000 and $12,000, excluding rebates and installation expenses.
The solar battery price has become more attractive with the introduction of federal rebates. In early 2025, the Government introduced a $2.3 billion national battery rebate program set to commence from July 1, 2025. This rebate is administered through the existing STC rebate program and offers around $370 per kWh or roughly 30% off the cost of installing a solar battery.

So, How Much Are Solar Batteries?
Solar Battery Installation Cost
As you’re already aware by now, the solar battery cost varies significantly based on several factors:
Battery Size and Capacity: Smaller 5kWh systems start around $6,000 installed, while larger 20kWh systems can exceed $20,000.
Brand and Quality: Premium brands like Tesla and Sonnen command higher prices but offer superior warranties and features.
Installation Complexity: Solar panel installation cost around $2,000, while complex retrofits can add an extra $3,000 to $5,000 to the total price.
Location: Remote areas or difficult access can increase installation costs compared to urban regions.
Government Rebates: The federal rebate reduces costs by approximately 30%, with additional state rebates available.
Are Solar Batteries Worth It?
The federal solar battery rebate is expected to significantly boost solar battery adoption in Australia, making the investment financially feasible for many households.
Recent analysis shows that solar batteries now offer reasonable payback periods:
| Rebate Scenario | Payback Period |
| Without rebates | 8-12 years |
| With the federal rebate | 6-8 years |
| With combined rebates | 4-6 years |
Beyond financial returns, solar batteries provide:
- Energy independence by reducing reliance on grid electricity
- Backup power to keep essential appliances running during outages
- Environmental benefits by maximising the use of clean solar energy
- Future-proofing through protection against rising electricity prices
Installation and Solar Panel Integration
You can add most battery systems to an existing solar panel installation, but the integration process will vary:
New Installation: Installing batteries with new solar panels is typically the most cost-effective option, allowing for an optimised system design from the start.
Retrofit Installation: Adding batteries to an existing solar system requires a thorough check of inverter compatibility and electrical panel capacity.
Hybrid Systems: Modern hybrid inverters can manage both solar panels and batteries, making them a great choice for new installations.
