Should I Get a Solar Battery in 2026?

For years, Australian homeowners have been putting solar panels on their roofs to generate clean electricity and reduce their reliance on the grid.

But there is one problem: the sun doesn't shine when most households use the most electricity.

Your solar panels can generate plenty of energy during the day, but once the sun goes down, your home may start drawing electricity from the grid again.

That is where a solar battery comes in.

And in 2026, with battery prices, technology and government incentives changing the equation, many Australian homeowners are asking:

“Should I finally add a battery to my solar system?”

The answer isn't the same for every home. But for the right household, 2026 could be a very interesting time to make the switch.

Solar Gives You Power. A Battery Helps You Keep It.

Think of your solar system as an energy generator.

During the day:

☀️ Solar panels → 🏠 Home → 🔋 Battery stores excess energy

At night:

🔋 Battery → 🏠 Home → Less reliance on the grid

Without a battery, excess solar electricity that you don't use immediately is generally exported to the grid. With a battery, you can store some of that energy and use it later.

This can be particularly useful for households that:

✔ Have significant excess solar during the day
✔ Want to increase their solar self-consumption
✔ Want greater energy independence
✔ Want battery backup capability, where the system is specifically designed for it.

The Australian Government's Cheaper Home Batteries Program is also making batteries more accessible, with around a 30% discount on eligible small-scale battery systems connected to new or existing rooftop solar.

So, Is a Battery Actually Worth It?

Here's the important part:

A battery isn't automatically a good investment for every household.

Your potential savings depend on your electricity consumption, solar generation, battery size, electricity tariff, feed-in tariff, installation cost and how much of the stored energy you actually use.

For example, a household that is already using most of its solar electricity during the day may get less additional value from a battery than a household that generates a lot of excess solar and uses most of its electricity after sunset.

That's why choosing a battery shouldn't simply be about buying the biggest battery available. It's about buying the right battery for your home.

What Makes 2026 Different?

The biggest change is the federal Cheaper Home Batteries Program.

Since 1 July 2025, eligible small-scale battery installations can receive a discount of around 30%, delivered through the Small-scale Renewable Energy Scheme. The discount is generally applied through participating retailers and installers.

The program applies to eligible batteries connected to new or existing rooftop solar, meaning you don't necessarily need to install solar and a battery at the same time. That could make 2026 a particularly interesting year for homeowners who already have solar but haven't yet added storage.

But there's an important catch.

The discount isn't a simple “30% off any battery” offer. Eligibility requirements apply, and the value depends on factors including the eligible battery capacity and the applicable program rules. It's also important to choose compliant equipment. The Clean Energy Council maintains an approved battery list, and approved products are required for the federal battery incentive.

Who Should Consider a Solar Battery?

A battery could make particular sense if your household looks something like this:

✔ You use lots of electricity at night

If your family cooks dinner, runs appliances, heats or cools the home and uses hot water mainly after the sun has gone down, storing daytime solar could help you use more of your own energy.

✔ You regularly export excess solar

If your solar system produces more electricity than your home needs during the day, a battery gives you another option: store some of that energy instead of exporting it immediately.

✔ You have time-of-use electricity pricing

Depending on your electricity plan, using stored solar energy during expensive periods may help reduce your grid purchases.

✔ You want backup capability

Some battery systems can provide backup power during an outage.

However, not every battery automatically provides backup power. Backup functionality needs to be specifically designed and configured as part of the installation.

Don't Stop at Solar and Batteries

Here's where a smart energy upgrade gets more interesting.

Your solar system and battery are only part of the picture. If you're trying to reduce household energy costs, look at the whole home.

Solar- Generate your own renewable electricity.

↓

Battery - Store excess solar and use more of it when you need it.

↓

Hot Water - A modern heat pump hot water system can use substantially less electricity than conventional electric hot water systems.

↓

Air Conditioning

Your heating and cooling system can also have a major impact on household energy consumption. Efficient reverse-cycle air conditioning can provide both heating and cooling from one system.

For eligible Victorian households, VEU currently offers discounts for replacing certain gas heating systems with efficient reverse-cycle air conditioners, with the available incentive depending on the existing system and replacement (Victorian Energy Upgrades, 2026).

Energy Efficiency

The goal isn't simply to generate more electricity. It's to use energy more intelligently.

Solar + battery + efficient hot water + efficient heating and cooling can work together as part of a more energy-efficient home.

Australia Is Moving Towards More Battery Storage

This isn't just a small trend. Australia experienced a huge increase in household battery installations during 2025.

The Clean Energy Council reported that 183,245 home batteries were sold in Australia during the second half of 2025 alone, more than the previous four years combined (Clean Energy Council, 2025).

Its 2026 Clean Energy Australia report also found that more than 268,000 home batteries were installed during 2025, representing a 260% increase year-on-year (Clean Energy Council, 2026).

Should You Get One in 2026?

A battery could be worth considering if:

✔ You already have solar
✔ You regularly export excess solar
✔ You use a lot of electricity after sunset
✔ You want to increase your solar self-consumption
✔ You have suitable electricity pricing
✔ You want backup capability
✔ You qualify for the current battery incentive

At BluPlanet, we help Australian homeowners look beyond a single appliance and consider a complete energy solution. From solar and battery storage to heat pump hot water and energy-efficient air conditioning.

Because the goal isn't simply to install more technology.

It's to help your home use energy smarter.

☀️ Generate it.

🔋 Store it.

💧 Heat it efficiently.

❄️ Use it smarter.

The change starts from you.
