With rising electricity costs and the upcoming 2025 rebate, more Gold Coast homeowners are exploring solar battery storage. But before making the switch, most people have a few key questions.
If you’re considering a solar battery for your Gold Coast home, this guide will help you understand what to expect and how to get the most from your system.
1. How does a solar battery work with my existing solar system?
A solar battery stores the excess energy your solar panels produce during the day. Instead of sending that unused power back to the grid, your system holds onto it for use in the evening, overnight, or during a power outage.
If you already have solar installed, you may be able to add a battery to your system depending on your current setup. The Auswell Energy team can assess your panels, inverter, and energy usage to let you know what’s possible.
2. How much does a solar battery cost on the Gold Coast?
The price of a solar battery depends on its size, brand, and how complex the installation is. Most systems for residential use fall between $8,000 and $15,000.
From July 2025, eligible Gold Coast households can apply for a federal rebate that will reduce the upfront cost of battery installation. For more on how the rebate works and who can apply, take a look at our solar rebate guide.
SWITCH TO SOLAR AND SAVE
3. Will it actually save me money?
In many cases, yes. A solar battery allows you to use more of your own solar power rather than buying electricity from the grid, especially in the evening when rates are usually higher.
If your energy provider uses time-of-use pricing, a battery helps you avoid paying peak rates by using stored energy instead. While it may take time to recoup the investment, many homeowners choose a battery for long-term savings and greater energy independence.
4. What size solar battery do I need?
The best battery size depends on how much energy your home uses, when you use it, and how much your solar system is generating.
For example:
- A small household might need a 5 to 7 kilowatt-hour battery
- Larger homes or families with high energy use may need 10 to 13 kilowatt-hours or more
At Auswell Energy, we assess your daily usage and solar production to recommend a system that fits your needs. Whether you’re starting from scratch or upgrading an existing setup, our advice is always tailored to your home and your goals.
5. How long do solar batteries last?
Most modern batteries last between 10 and 15 years, depending on the brand, usage patterns, and how well they’re maintained. Many come with a 10-year warranty as standard.
At Auswell, we only install trusted battery brands with proven reliability. With proper care and regular monitoring, your system should continue to support your home for years to come.
