Frequent power outages, unreliable grid connection, sky-high electricity bills, and to top it off, your solar panels are exporting excess energy back to the grid, for a very low feed-in-tariff.

Do all these scenarios sound familiar? Your answer might be yes!

These challenges have become increasingly common across Australia, encouraging more and more homeowners to consider solar battery storage systems.

Why? Because they want to take control of their energy, store surplus solar power, and reduce reliance on the grid.

But then again, people often get perplexed, and their biggest question remains: Should I get a Solar Battery Storage System in Australia?

Well, the answer can be yes in many cases, such as a battery can offer energy independence, ensure better bill savings, and provide peace of mind during unexpected power outages, but it’s not a one-size-fits-all solution.

There are circumstances where a battery may not be necessary or even cost-effective.

In this guide, we’ll break down when it makes sense and all the pros and cons you need to know before making the investment.

In this blog post:

Why You Need Battery Storage Now?

According to data, Australia has surpassed 3.9 million rooftop solar installations, generating more than 37 GW of PV capacity, which is about 20% of electricity in the National Electricity Market in 2024 and early 2025.

Undoubtedly, the country’s strong renewable energy targets, sustainability goals, and the clean‑energy revolution have brought solar power affordability, but the next step in self‑reliance is battery storage.

Data from The Guardian says that 1 in 5 new solar installs in 2025 now includes a home battery, versus 1 in 20 just a few years ago, representing a significant leap in adoption.

Moreover, the recent launch of the Cheaper Home Batteries program has driven this uptake even further, with over 11,500 battery units installed in just the first three weeks from July 1, and around 1,000 installations per day.

Overall, the Australian energy market is evolving rapidly. Average household battery size has climbed to about 17 kWh from 10–12 kWh previously.

Hence, the experts are assuming that 10 GW of new battery capacity will be added over the next five years, competing with Australia’s current coal‑fired capacity.

What Am I Missing Out on Without Solar Batteries?

Honestly? You’re missing out on the best part of going solar.

Renewable sources of energy like solar, hydro, and wind make us feel empowered. For example, solar batteries lower your electricity bills, minimize grid dependency, and also help to reduce your carbon footprint.

But here’s the catch! Without battery storage, you’re only halfway there!

The true magic of solar power isn’t just in producing clean energy; it’s storing and using it efficiently.

A solar battery lets you store excess energy and use it when the sun goes down or the grid goes out. It’s the key to real energy independence. Therefore, ultimately, getting a battery is what makes your solar system truly yours.

Here’s a list of what you’re missing out on without a solar battery:

Energy Independence

Batteries help you to stay powered even during blackouts or grid failures. With energy storage, you don’t have to think of fuel price volatility and supply-demand disruption in the Australian energy market.

Maximized Savings

Adding a solar battery to your solar PV system allows you to use your own stored energy at night instead of repurchasing it at high rates. It also reduces grid pressure during peak hours, restoring grid stability.

Better Return on Investment ROI

Tired of Australian low feed-in-tariff rates?

Make full use of your solar system by storing excess power at a low price rather than exporting it. Solar panel and battery systems can be a powerful duo for Australian households.

Lower Carbon Footprint

Despite the steady growth in solar, wind, and hydro, fossil fuels still dominate the grid. Fossil fuels supplied approximately 64% of Australia’s total electricity generation, while coal alone accounted for around 45%.

These stats highlight why solar battery storage is so valuable. By storing surplus solar energy, homeowners can reduce their reliance on a grid that still runs on coal and gas.

Peace of Mind

Enjoy 24/7 uninterrupted power, no matter what’s happening outside.

Besides powering urban homes and businesses, batteries also provide reliable power backup for off-grid living at night when your solar panel can’t produce, ensuring peace of mind.

What Size Solar Battery Do I Need?

While choosing the battery size, it isn’t just about picking the biggest one you can afford; it’s about matching your household’s energy consumption pattern. There is no one-size battery that will make financial or functional sense for everyone.

Nevertheless, if you have an average family of four with no exceptional power demands, you may get by with a 10kWh to 12kWh battery bank as a ready-to-roll backup system.

Well, this is just an estimation, as we have no idea of your power needs, because selecting a battery is highly subjective to the household in question.

With that being said, you can get a good idea of how much power you use on average by analyzing your electric bill copy. Also, keeping track of which appliances you use the most and which ones require the most power will help you.

So, to figure out the ideal battery size for your home, you need to consider three most important things:

Your Daily Energy Usage

Check your electricity bill for your average daily consumption (in kWh). Most Australian homes use between 15 to 25 kWh per day.

Your Solar System Output

How much excess solar energy are you generating during the day? That’s the power you’ll store to use later rather than exporting.

Your Nighttime Power Usage

A battery is most useful at night or during grid outages. So, estimate how much power you typically use after sunset. However, by using a battery, you can also get the freedom of living off the grid.

Sizing Up: The Ideal Home Battery for Aussies!

For small households and light usage, a 5 kWh battery will be suitable.

For average Australian households, adding a 10 kWh battery would be enough.

Large homes and high-energy users will need a 13 to 15 kWh system.

For full independence, off-grid living, or blackout protection, you may require a larger battery size of 20+ kWh.

How Much Do Solar Batteries Cost?

Previously, you would have to pay between $3000 and $3600 for the battery alone, plus the cost of installation, for every kWh of solar battery storage.

However, you can currently expect to pay between $1200 and $1400 for each kWh of solar battery storage. That is a price reduction of approximately 52%, and things will only get better from here.

Does that imply solar batteries are cheap now? Not really, but the cost is well justified by the pros of having a battery storage system.

Also, while paying for solar batteries, you have to consider many other factors like the type of battery, your solar panel system configurations and compatibility, brand, and installation partner.

These will significantly influence the price range of battery storage.

Is a Solar Battery Worth It | Pros and Cons at a Glance

It’s okay to feel a little overwhelmed while deciding to invest your hard-earned money in a battery.

So, here we’ve listed the pros and cons of having a solar battery to help you in the decision-making process.

Benefits of Solar Battery Storage

Solar batteries help you become self-sustaining.

You don’t have to care about power outages anymore

In the event of any natural disaster, you will still have a power source

Battery prices are dropping significantly as we speak

During peak hours, grid electricity prices increase due to high demand; you can avoid paying a high price and use your battery. It’s essentially free energy, as solar generates energy from the sun.

Reduced carbon footprint as the battery stores energy from a renewable source.

Advantages of battery for the grid and national energy system:

Batteries support Virtual Power Plants (VPPs). In 2025, consumers get financial bonuses (AUD 250‑400) for joining, plus grid benefits via distributed dispatchable power.

Grid‑scale batteries like Victoria Big Battery or Hornsdale Power Reserve are increasing system resilience by storing large amounts of renewable energy and reducing blackout risk.

Drawbacks of Solar Battery Storage

One of the biggest barriers is that solar batteries have a high upfront cost, which makes installation harder for residents.

Home batteries require physical space, proper ventilation, and can’t always be placed just anywhere, especially in smaller homes or apartments.

Most batteries, like lithium-ion batteries, last 5 to 15 years, meaning they may need replacement during your solar system’s lifetime.

While many systems are low-maintenance, some may require software updates, monitoring, or even professional servicing over time.

Battery production involves mining and processing materials like lithium or lead, which raise environmental and ethical concerns.

Should You Buy a Solar Battery?: Here’s the Final Call!

You should consider buying a solar battery if several key factors align with your situation.

First, it’s a strong financial move if you live in a state where federal and state incentives can significantly reduce the upfront cost. This can make the investment far more affordable.

A solar battery can be especially worthwhile if you value having backup power during outages, lowering your electricity bills, and gaining a measure of energy independence from the grid.

Additionally, you should be comfortable with taking a few extra steps to get the most value out of your system, such as joining a virtual power plant (VPP), which allows your battery to participate in grid services in exchange for modest returns.

Finally, it’s worth noting that rebates decline annually, and early adopters get the most value.

Takeaway Thoughts

Installing a solar battery in Australia in mid‑2025 offers substantial financial, environmental, and energy‑security benefits, especially if you qualify for multiple subsidies and have good solar capacity.

With rebates shrinking after 2025 and demand surging, early movers stand to benefit most.

By helping balance the grid and reduce dependence on fossil fuels, home battery adoption contributes significantly to Australia’s national goals of 82% renewable energy by 2030.

It’s not just about savings; it’s about being part of a smarter, cleaner, more resilient electricity future for Australia.

Many Americans are starting to feel like the lady whose observations we see at left.

Exactly how this moves forward from here is anyone’s guess. Maybe the Democrats gain a huge majority in Congress in 2026 and then impeach and convict Trump–perhaps joined by lots of Republicans.

There are plenty of different scenarios.

As shown in this short video, Donald Trump says that climate change is the biggest con job ever perpetrated on Earth.

We are to believe that Trump a) understands the subject better than the thousands of our planet’s top scientists, located in countries all around the globe, and b) he’s telling the truth, where they have somehow gotten together and conspired to lie.

Renting in Victoria often comes with its share of compromises, especially when it comes to heating and cooling.

In Victoria, most households face high bills and reduced comfort because their old gas heaters kick in during winter or inefficient split-system air conditioners struggle to keep homes cool throughout summer.

Fortunately, there’s a golden opportunity many residents don’t know about: the Victorian Energy Upgrades (VEU) Program. This government-backed initiative offers meaningful rebates and discounts for efficient heating and cooling and other home upgrades.

But the question is: Do rental properties qualify for the VEU rebates?

The answer is yes, but there are a few important things tenants need to know.

Therefore, in this article, we’ll guide you through how tenants in VIC can benefit from VEU air con Upgrade, how the landlord consent process works, and share some real-world examples that you can follow to get started.

So, let’s begin!

In this blog post:

Understanding VEU Air Con Rebates: Can Renters Benefit?

As mentioned earlier, the Victorian government has introduced the Victorian Energy Upgrades (VEU) program to help
households and businesses reduce energy costs and lower greenhouse gas emissions.

Under this scheme, accredited providers offer rebates or discounts on the installation of energy-efficient products,
including reverse-cycle
air conditioners that replace older, inefficient systems in your home.

How Does the VEU Rebate Program Work?

The government issues “VEU certificates” for each upgrade, which energy companies then buy to meet their
emissions-reduction targets. This trading system allows households to receive up-front discounts.

Significantly, tenants can also benefit from the rebate if they have their landlord’s approval for installing air conditioners.

In rental homes, this upgrade not only improves comfort and reduces electricity bills but also helps landlords meet
Victoria’s minimum energy-efficiency
standards for rental properties.

Eager to know more?

Here is how renters can benefit through VEU air con Upgrades:

Lower energy bills

Upgrading to a high-efficiency reverse-cycle air conditioner under the VEU scheme can significantly reduce your
heating and cooling costs.

For example, recent data represents estimated savings of $120 to $1,100 per year, depending
on the size or type
of
upgrade.

Switching to efficient heating
and cooling systems helps reduce ongoing operational costs.
In your home, better temperature control means you’re less reliant on inefficient systems, like gas-burning
heaters or fans.

Improved comfort and living conditions

In a rental property, installing a modern, energy-efficient cooling system means better indoor comfort.
This VEU air con upgrade can be especially relevant in rentals where older systems may struggle or be
inefficient.

Eligibility and access permission as a tenant

Tenants can access upgrades under the VEU program, though you’ll need to coordinate with the landowner.
The best part is that there are no income thresholds to meet. The program is broadly available to Victorian
households and rental properties.
The discount is applied via an accredited provider, so the cost to the tenant (or the landlord/tenant jointly)
is reduced upfront.

Air Con Upgrade adds value to the rental property

Even though this VEU rebate directly benefits the property owner or landlord in terms of value appeal, tenants
also benefit by renting a property with better systems that likely have fewer repairs or maintenance issues.
Upgrades reduce maintenance
tasks for tenants, as older systems are more likely to break, causing discomfort or disputes over
repairs.

Do Tenants Really Need Landlord Consent? | The Approval Process Explained!

If you are living in a rental property in VIC and thinking about upgrading your air conditioning system through the
VEU program, you might be wondering — do I need my landlord’s approval before installing the new unit?

Well, since you don’t own the property you’re renting, one of the first steps as a tenant is to talk with your
landlord and seek permission.

It’s important to check in with your landlord before making any upgrades or installations. It helps avoid common mistakes
that disqualify you from a rebate, ensures compliance with your lease, and keeps everything running
smoothly.

Here’s how the landlord approval process usually works and what you should do to get landlord approval
fast:

Initiate the conversation

As a tenant, you can raise the possibility: “Would you be willing to upgrade the heating/cooling system under the
VEU
rebate scheme?” You can emphasis the long-term benefits to the landowner, such as lower bills, greater comfort,
and
improved property value.

Check eligibility together: here’s what to check!

Confirm the property has existed for more than 2 years.
Verify whether the existing system is eligible for replacement, e.g. an old gas heater or a low-efficiency
AC
unit.
Not all the brands
and
models are eligible, so check the public
registry to find a suitable one.
Make sure the upgrade has not been claimed for that property before. The program won’t allow duplicate
claims.
Select a VEU-approved product and an accredited installer, such as Cyanergy.

The landlord gives consent

Your landlord or rental provider must agree to the upgrade. Many installers note that rental properties can
access
the scheme only when the owner provides landlord approval.

Transparent discussion on cost & contract

Before installing a system, a contract with the installer will outline the rebate and installation details,
including
who pays upfront.

It’s wise for both the landlord and tenant to review it.

Installation & rebate claim

The installer handles the application under the VEU scheme, ensuring that the discount/rebate is applied. The
landlord will likely be the applicant (since they’re the property owner), but tenants can initiate or support
the
application.

Post-installation: Allocation of benefits

After installation, the improved system delivers reduced energy use. The agreement between landlord and tenant
should
clarify how those savings are handled.

Pro Tips Every Tenant Should Know During the Rental Process

To get the most out of this opportunity, here are some best practices especially tailored for tenants:

Get everything in writing, keep records, and retain a copy of the document for both the landlord and you.
Request an estimate that clearly outlines the rebate process or discount amount, allowing you to see the actual cost.
Ask the installer to clarify the warranty, ongoing maintenance, and any other relevant details.
Ensure the landlord agrees to your shared arrangement, including the cost, benefits, and timeframe, before committing to it.

How are Costs and Incentives Shared?

One of the main questions is: when a tenant benefits, who pays for what? And how incentives are distributed?

Well, under the VEU scheme, here’s how it typically works:

Incentives offered

According to the Victorian government’s heating and cooling factsheet, installing an efficient reverse-cycle air conditioner can result in significant savings. For example:
- Up to about $840 when replacing a hard-wired electric resistance room heater ranging from 3 kW-9 kW in a non-ducted setting.
- Up to $2,520 for replacing a ducted gas heater and installing 4 split systems (1×8 kW + 3×3 kW).
The program also notes that for rental properties, benefits apply: the regulatory impact assessment states:
“The VEU program is available to renters. The program encourages collaboration between rental providers and tenants to work together on upgrades.”

So, who bears the cost?

When discussing cost-sharing for installing an air conditioning system in a rental property, the tenant may offer to contribute by paying higher rent, extending the lease term, or sharing the energy savings.

This helps both the landlord and tenants to secure the upgrade quickly.

However, in most cases, the landlord pays the bulk of the cost or arranges for the installer to claim the rebate or discount, reducing the upfront cost.

Then, the installer essentially offsets your rebate via VEECs (Victorian Energy Efficiency Certificates) and passes the benefit on to the customer.

The rebate is usually applied up front, reducing the installation cost, and the amount depends on the type of system you remove and the system you install.

Sharing Benefits Between Landlord and Tenants: A Collaborative Approach

Upgrading the air conditioner or installing a new unit under the VEU rebate program can benefit both tenants and
landlords. While tenants benefit from lower power bills and greater comfort, landlords benefit from improved
property value.

Let’s picture this:

Example Scenario

The tenant initiates the upgrade, and the landlord agrees. The installer’s quote shows the system costs $4,000, with
a $2,500 rebate, so the net cost payable is $1,500.

The tenant might offer to sign a 2-3-year lease extension, providing the landlord with stability in return for a
share of the savings, such as lower power bills or a slight rent increase.
Landlord receives a modern upgrade, a better energy rating, and reduced risk.
Tenants enjoy comfort and lower bills, all while living in a rental.

However, even with a rebate, the property owner must meet the minimum customer contribution.

For instance, for a non-ducted reverse-cycle air conditioner under 10 kW, the minimum cost is $200 for a multi–split
system and $1,000 for a ducted system.

So, remember! While rebates are generous, they don’t always cover everything.
