Should You Get a Solar Battery or Stay on a Feed-in Tariff?
Should You Get a Solar Battery or Stay on a Feed-in Tariff?
Solar panels have become a common sight on Australian rooftops, driven by the country’s abundant sunshine, rising electricity costs, and strong government support.
But over the past decade, the economics of solar have shifted as feed-in tariffs have steadily declined.
The way Victorian homeowners benefit from solar has completely changed. Generating power alone is no longer enough. What matters now is how and when you use it.
In 2026, if you’re still thinking that exporting electricity to the grid is the best way to earn from your system, you might be leaving hundreds or even thousands of dollars on the table each year.
So, the question is: should you stick with a feed-in tariff or invest in a solar battery?
Let’s explore which option delivers the best value for Victorian homes in 2026.
Understanding Feed-in Tariffs & How They Work
Before diving deeper into the comparison, it’s worth taking a step back and knowing what a Feed-in Tariff is and how it actually works.
Feed-in tariffs are simple. When your solar panels generate more electricity than your household needs, the excess energy is exported back to the grid. In return, your energy retailer pays you a set rate for each unit of electricity you export.
Sounds like a win-win, right? Well, to some extent, it still is!
Feed-in tariff benefits you by:
- Lowering your electricity bills
- Earning small credits for unused energy
- Making your home more energy efficient
However, the value of exported energy is now extremely low. So, even though FiTs still play a role, for many residents, they’re no longer the main moneymaker.
Solar Batteries: Turn Your Solar into Real Savings
Sometimes one shift changes everything. That’s where solar batteries come in.
This technology is reshaping how Australians use and benefit from their solar energy.
Here, instead of sending excess power to the grid for a small return, you can store it and use it when electricity is most expensive, like at night or during peak times.
So, here’s the reality:
No battery? You sell low and buy high.
With a battery? You store energy and avoid high electricity bills.
This single upgrade can transform your solar from a passive system into an active money-saver, turning every unit of energy into maximum value.
Therefore, adding solar batteries is not just an improvement. It’s a game-changer.
Solar Battery vs Feed-in Tariff: From Earnings to Energy Independence
Here’s the blunt truth:
A few years back, feed-in tariffs (FiTs) were incredibly generous. Some Australians were getting paid premium rates just by sending excess solar energy back to the grid. It felt like making money from your rooftop.
Fast forward, and things look very different.
With millions of solar systems installed across the country, the grid is now flooded with cheap daytime electricity. As a result, feed-in tariffs have dropped significantly.
According to recent market trends and insights, most households today earn only a few cents per kilowatt-hour for exported power, typically between 3 and 10 cents in Victoria.
Meanwhile, the electricity you buy from the grid can cost anywhere from 25 to 40 cents per kWh.
Well, that gap changes everything. Using solar power directly in the home can be worth roughly 3 to 6 times more than exporting it to the grid.
This makes you think twice about exporting.
However, while the lower upfront cost may make feed-in tariffs look more attractive, the table does not fully reflect the long-term benefits of solar batteries, including greater energy independence, energy resilience, and reduced electricity costs.
The truth is, as Feed-in Tariffs continue to decline, solar batteries can help households get more value from their solar generation.
Which Option Saves You More? The Real Cost Analysis
Let’s see the math behind the savings and find out which choice puts more money in your pocket.
For instance, imagine your solar system produces 10 kWh of excess energy during a sunny day in Victoria.
Over a year, that adds up to:
10 kWh × 365 days = 3,650 kWh of excess solar energy annually
Option 1: Selling Your Solar Back to the Grid
Victoria’s proposed minimum solar feed-in tariff for 2025–26 is just 0.04 cents per kWh. That means every unit of electricity you export to the grid is worth almost nothing.
Using that minimum rate:
3,650 kWh × $0.0004 = $1.46 per year
Even with a more common retail feed-in tariff of around 3 to 10 cents per kWh, the return is still relatively low:
- At 3 cents/kWh = $109.50 per year
- At 10 cents/kWh = $365 per year
Option 2: Storing Solar Energy in a Battery
In Victoria, grid electricity prices commonly range from around 26 to 35 cents per kWh.
That means the same 3,650 kWh could save you:
- At 26 cents/kWh = $949 per year
- At 35 cents/kWh = $1,278 per year
Note: However, pricing can vary depending on location and other factors, so it’s best to confirm the latest rates directly with your energy retailer.
The Difference Is Huge
When you compare the two options, the value gap becomes clear:
- Selling solar to the grid could return as little as $1.46 to a few hundred dollars per year.
- Storing and using your own solar energy could save close to $1,000–$1,300 annually.
Therefore, instead of giving away excess solar power for cents or fractions of a cent, Victorian residents find it attractive to use solar batteries, maximising the value of every kilowatt-hour they generate.
Cheaper Home Batteries: Australia’s Rebate Updates 2026
One of the biggest reasons solar batteries are gaining momentum isn’t just rising electricity prices; it’s government support.
The Australian Government’s Cheaper Home Batteries Program is making battery storage far more accessible for households. They offer generous rebates of about 30% to reduce the upfront cost of installing a home battery system.
On 5 February 2026, some changes to the program were finalised, introducing two key differences that are effective from 1 May 2026:
- STC Factor Reduced Faster: The battery rebate now decreases every 6 months and at a higher rate, meaning the discount gradually becomes smaller over time.
- Support Now Depends on Battery Size: The STC Factor is applied at 100% for the first 14 kWh of battery capacity, 60% for capacity between 14–28 kWh, and 15% for capacity between 28–50 kWh.
So ultimately, when you combine these rebates with the declining value of feed-in tariffs, the financial equation shifts even further.
In the past, solar batteries were often seen as an option, but in 2026, they’re quickly becoming a financially smart upgrade for many Victorian homes.
Parting Thoughts
The solar game in Australia has definitely changed. A few years ago, solar owners focused on earning money through feed-in tariffs. Now, it’s all about using more of your own solar power instead of sending it back to the grid.
So the real question today isn’t: “How much can I sell my electricity for?”
It’s: “How much expensive electricity can I avoid buying?”
Once you start looking at solar that way, everything changes. Your focus shifts from chasing small export credits to building real long-term savings and better energy freedom.
So, if you’re considering upgrading your system or adding a battery, now is the perfect time to run the numbers and see what works best for your home.
