Thinking about investing in solar battery storage? You’re not alone. With rising energy prices and increasing interest in renewable energy, more Australians are exploring the benefits of solar and battery storage systems to reduce reliance on the grid, cut costs, and gain energy independence.
But is it worth the upfront investment? And what should you consider before making the switch? This blog will break down the essentials so you can make an informed decision about whether solar battery storage is right for your home.
What Is solar battery storage ?
Solar battery storage refers to a system that stores excess solar power generated by your panels during the day for use later—especially during the evening or during grid outages. Instead of sending unused electricity back to the grid, battery storage allows you to use that energy yourself, increasing your energy efficiency and autonomy.
These systems typically include:
Solar panels
A solar inverter
Battery storage units
A battery management system (BMS)
How Solar Battery Storage Works?
During the day, your solar panels collect sunlight and convert it into electricity. Some of that power is used immediately in your home. When you produce more than you consume, the excess is stored in your battery instead of being exported to the grid. At night or during blackouts, your home draws power from the battery.
This setup, often referred to as battery storage solar power, enhances self-sufficiency and protects you from price hikes or outages.
Advantages of Solar and Battery Storage Systems
Energy Independence : Say goodbye to total reliance on energy retailers. With solar and battery storage systems, you're in control of when and how you use your energy.
Lower Power Bills : By using stored energy at night or during peak tariff periods, you can significantly reduce your electricity costs.
Backup During Blackouts : Most lithium batteries support backup power, keeping essentials running during power outages.
Better Use of Solar : Storing excess energy for later means less waste and greater efficiency from your solar panel investment.
Environmental Impact : You reduce your carbon footprint by increasing your use of renewable energy.
Is Solar Battery Storage Worth the Cost?
Let’s talk dollars. A typical 6.6kW solar system paired with a 10kWh lithium-ion battery might cost between $12,000 and $16,000. Without storage, a standard solar-only setup might cost around $6,000.
Here’s where the federal and state rebates come into play. Depending on your location in Australia, you may be eligible for substantial incentives that reduce the cost of solar battery storage by thousands of dollars.
Over the long term, these systems often pay for themselves through bill savings and increased energy security.
Who Should Consider Investing in Solar Battery Storage?
Homeowners with High Evening Usage: If your household uses a lot of power at night, a battery makes economic sense.
Remote or Off-Grid Properties: For rural areas with unreliable power supply, battery storage is essential.
Sustainability Advocates: If reducing carbon emissions is your goal, battery storage is the next step after solar panels.
Homes with VPP Access: Virtual Power Plants (VPPs) allow battery owners to earn money by contributing stored power to the grid.
Popular Solar Battery Brands in Australia
Tesla Powerwall
LG Chem RESU
Sonnen
BYD Battery-Box
Alpha ESS
Each of these brands offers a range of features and warranty terms. Be sure to compare round-trip efficiency, lifespan, and support.
Maintenance and Lifespan
Most modern batteries are low maintenance and last 10–15 years. Lithium-ion batteries tend to perform better over time than older lead-acid models. It’s important to work with certified installers to ensure warranty and safety standards are met.
What Rebates Are Available in Australia?
Federal Battery Rebate (2025): Up to ~$4,000 savings depending on battery capacity.
WA: Up to $3,800 in rebates + $10,000 interest-free loans.
NT: Up to $12,000 off with additional feed-in incentives.
NSW: Up to $1,500 for VPP participants.
Other states may offer interest-free loans or other incentives, so check with your local authorities or platforms like UtilityChoice.

Is battery storage worth it without solar panels?
It’s not common, as batteries are most cost-effective when paired with solar.
What size battery do I need?
A typical home uses 8–12kWh per evening, so a 10kWh battery is a good starting point.
Do solar batteries work during a blackout?
Yes, but only if they are configured for backup and not just for time-shifting.
What is a Virtual Power Plant (VPP)?
A network that links batteries to the grid, allowing you to sell stored energy.
