[DECEMBER 2025 UPDATE] The Solar Battery Rebate Australians Loved Is Gone. Here’s How to Still Save BIG.

QUICK TAKEAWAYS:

✔ Highest value is in January 2026.
✔ Home battery rebate changes drop after 1 May 2026 and shrink fast. Rebates drop every 6 months.
✔ Batteries must be paired with solar PV.
✔ Bigger solar batteries after May get much smaller rebates.

Australia has officially changed solar battery rebates.

What worked before doesn’t work the same way now.

There is still a government-backed rebate that can cut up to 30% off the upfront cost of a home battery and lower power bills long-term. But it’s not a bonus you and your “electrician near me” can rely on later.

This rebate shrinks every six months.
Wait, and the value drops. Miss the window, and you pay more for the same system.

Battery prices aren’t coming down.
Rebates are.
Install availability is tightening.

That pressure you’re noticing is real. And it’s time-sensitive.

Below is what Underwood and the rest of Australia homeowners, landlords and business owners need to know right now to lock in the maximum solar power rebate while it’s still available.

Let’s start!

The Cheaper Home Batteries Program: What is The Battery Rebate in Australia 2025, December? 

The Cheaper Home Batteries Program is live. And yes, it matters to you because…

• It provides you around 30% off the upfront cost of a small-scale home battery — real savings you feel immediately, not later
• Instant discount at the time of sale through government certificates applied by your installer — no unnecessary forms, follow-ups, no stress
• This works with new or existing solar as long as the battery is connected to solar power — simple eligibility for battery rebate in NSW, terms apply.
• This is why solar battery prices suddenly feel affordable — what once felt out of reach now feels smart, practical, and empowering
• The value shrinks over time by design — wait too long and you don’t just delay savings of your federal government solar battery rebate, but you lose part of the deal.

Your move. Lock in today’s value or watch the savings quietly slip away.

How It Works: The Rebate & The May 1 Deadline

The Government buys the certificates (STCs) for you. You do not touch them. You just get instant savings.

Because 2025 installation slots are now fully booked, your goal is to lock in the Early 2026 Rate before the rules change again.

1. The “Safe Zone” (January – April 2026):

✔ You get the 8.4 certificate rate.
✔ This is now the strongest rebate available for new bookings.
✔ You must install before May 1 to secure this tier.

2. The “Drop Zone” (After 1 May 2026):

⚠ The rate crashes to 6.8.
⚠ The “Tiering” Penalty Begins: This is the single biggest update most homeowners haven’t heard. From May 1, the battery rebate will shrink based on battery size:

• 0–14 kWh: Gets full rebate value.
• 14.1–28 kWh: Gets only 60% of the value.
• 28.1–50 kWh: Gets only 15% of the value.

What This Means For Your Wallet: If you wait until May 2026 to install a big battery, most of your rebate disappears.

• Example: A 30 kWh system qualifies for ~$9,072 if installed in early 2026, but that figure drops to just ~$5,549 if you wait until May.
• After May 1: That rebate could shrink to just a few thousand dollars.

The Bottom Line: The “9.3” rate is gone. The “8.4” rate is available right now for early 2026 bookings. But if you delay until May, you fall off the cliff to “6.8” and get hit with the new size penalties.

How Much You Could Save (Examples)

The rebate is based on the “usable” power of your battery, which helps offset how much are solar batteries in your area.

Look at the money you lose if you wait until the May 1 deadline:

*Includes the impact of size-based tapering (the “Tiering” rule) starting May 1.

*Estimates based on STC price of $36. Admin fees may vary. Subject to market changes.

The Simple Truth:

• January – April: You get 8.4 certificates per unit. (The Last Good Deal)
• May 1 Onwards: The rate drops to 6.8, AND the government begins “tapering” the rebate for larger systems.
• The Big Battery Penalty: After May 1, any capacity above 14 kWh gets a reduced rebate, and anything over 28 kWh gets almost zero support.

Don’t hand $700–$8,800 back to the government. Lock in the January rate now.

Why You Must Act This January (Before May 1)

The rebate is shrinking. If you wait, you lose money in two ways:

1. Time: The rebate drops every 6 months.
2. Size: Big batteries get huge cuts after May 1.

The “Double Squeeze” From 1 May 2026, new rules kick in. If you buy a large battery (over 28 kWh) after this date, your rebate drops to just 15%.

That means you could lose thousands of dollars just by waiting a few months. Smart homeowners are acting now to beat the deadline.

It’s Not Just About Money. It’s About Your Life: 

🔥 Slash Your Bills: Store cheap solar power to use when prices are high. 

🔥 Backup Solar Battery Storage: Keep the Netflix Fun on when the power goes out . 

🔥 Freedom: Protect yourself from rising energy costs. 

🔥 Future-Proof: Get your home ready for electric cars.

The Hard Truth: Waiting Costs You Big Time 

🚨 Rebates Go Down: Every 6 months until 2030, the payout gets smaller. 

🚨 Big Systems Get Cut: After May 1, you get paid much less for extra storage. 

🚨 Funding Is Limited: Everyone wants this. The money could run out fast. 

🚨 Delays Cost Cash: Prices are rising. Installers are booked out.

The Bottom Line: If you buy this January, you lock in the big rebate. If you wait, you pay more and get less back.

This chance will not last.

The early bird gets the biggest battery rebate.

Subject to Regulations being made, changes to the Cheaper Home Batteries Program will come into effect from 1 May 2026.

The Hard Battery Rebate Truth: Waiting Costs You

You’ll hear people say “just wait for prices to come down.”

But here’s the real truth:

• Rebate value is highest today
• Battery prices are not dropping fast enough to offset rebate declines
• Installers are getting booked out
• DELAYS = LESS SAVINGS

The longer you wait, the fewer incentives you get and the more you pay.

How to Secure Your Battery Rebate Before It Shrinks

Here’s your action plan:

1. Get quotes from accredited installers NOW that Underwood locals 100% trust 
2. Choose the right size battery for your usage
3. Ensure the install date is before 1 May 2026 to lock in max rebate
4. Ask your installer to handle STCs at time of installation
5. Pair with solar PV if you haven’t already

The single biggest leverage you have right now is timing. Every month you delay reduces your rebate.
