Solar incentives in Australia change often, and they are easy to misread. There is no US-style solar tax credit here, but there is a stack of federal and NSW programs that can take thousands off a new system. This guide explains each one in plain English, what it is worth, and how they fit together on a real Solar Chief quote.
For a full side-by-side breakdown, see our NSW solar and battery rebate guide.
The four incentives that matter in 2026
| Incentive | Who runs it | What you get | Applied |
|---|---|---|---|
| STC rebate | Australian Government | Point-of-sale discount on eligible solar | At quote, by installer |
| Cheaper Home Batteries Program | Australian Government | Around 30% off eligible batteries (5-100 kWh) | At point of sale |
| Home Energy Saver loan | NSW Government | Zero-interest loan up to $15,000 | You apply via NSW portal |
| Battery-to-VPP incentive | NSW Government | Up to around $1,500 upfront | Via participating programs |
1. The STC rebate (the closest thing to a tax credit)
The Small-scale Technology Certificate (STC) rebate is the federal mechanism that lowers the cost of most rooftop solar systems. When your installer registers an eligible system, it creates STCs that are then traded to reduce your upfront price.
Key points:
- It is a point-of-sale discount, not a refund you claim later.
- The value depends on system size and your location, and it is already reflected in Solar Chief's published package prices.
- It applies to eligible solar generation equipment, and sits separately from battery programs.
You do not apply for it yourself. Your CEC-accredited installer handles it.
2. The Cheaper Home Batteries Program
The Australian Government's Cheaper Home Batteries Program gives eligible households, small businesses and community organisations a discount of around 30% off the upfront cost of battery systems between 5 and 100 kWh.
The discount is applied at point of sale by the installer. The dollar amount scales with battery size, so a larger battery means a larger discount. On a typical 28 kWh Solar Chief battery package, the discount works out to roughly $4,600.
A CEC-accredited battery installer is required, which Solar Chief is.
3. The NSW Home Energy Saver loan and discount
The NSW Home Energy Saver program, launched on 17 June 2026, has two parts:
- A zero-interest loan of up to $15,000, repayable over 10 years, for households with a combined taxable income up to $210,000.
- A targeted discount of up to $4,000 for households earning under $80,000 or holding an eligible concession card, expected to open later in 2026.
Rooftop solar and battery storage are both explicitly eligible. The loan finances the balance after the STC rebate and the battery discount are applied.
4. The NSW battery-to-VPP incentive
NSW households and small businesses can receive an upfront payment of up to around $1,500 for connecting an eligible battery to a Virtual Power Plant. This stacks on top of the federal battery discount, which is what makes 2026 an unusually good time to add storage.
What about "tax credits"?
It is worth being direct here. Some solar content talks about "tax credits" loosely. In Australia there is no personal solar tax credit of the kind you see in the United States. The STC rebate plays that role, and it is applied at the point of sale rather than through a tax return.
For businesses, there are separate considerations: small businesses can access the Cheaper Home Batteries Program, and solar and battery assets may have tax or depreciation treatment available. Always confirm any tax claim with your accountant before relying on it.
How they stack on a real system
Imagine a complete solar and battery package. The STC rebate lowers the solar portion, the Cheaper Home Batteries discount lowers the battery portion, and the NSW zero-interest loan can then spread the remaining balance over 10 years at no interest.
Not every program applies to every home, and eligibility sits with the relevant government or program provider. Solar Chief confirms what applies to your property during quoting.
Frequently asked questions
Is there a federal tax credit for solar in Australia?
No. Australia does not offer a US-style solar tax credit. The equivalent is the federal STC rebate, a point-of-sale discount applied by your installer.
Can I combine the STC rebate with the battery discount and the NSW loan?
Yes. The STC rebate and the Cheaper Home Batteries Program discount reduce the upfront price, and the Home Energy Saver loan can finance the remaining balance at zero interest.
Do I apply for the STC rebate myself?
No. For eligible systems it is applied at point of sale by your CEC-accredited installer.
