Advice based on your bills
We look at how much power your household uses and when, so you know what size of system makes sense before anyone quotes. Sometimes the honest answer is "not yet".

The federal battery discount steps down on 1 January 2027
The Cheaper Home Batteries Program takes a discount off the price of an eligible home battery. The discount comes from certificates, and the number of certificates per kWh drops every January and July, so the same battery attracts a smaller discount next year.
Rooftop solar still gets its own up-front discount through small-scale technology certificates (STCs), which also falls each year until the scheme ends in 2030.
Battery discount schedule
| Installed | Certificates per kWh |
|---|---|
| May to Dec 2026 | 6.8 |
| Jan to Jun 2027 | 5.7 |
| Jul to Dec 2027 | 5.2 |
| Jan to Jun 2028 | 4.6 |
For the first 14 kWh of usable capacity. Larger batteries get less per kWh above that. Checked 1 November 2026.

Questions
Common questions
What does Swancomm do?
We help Hills District homeowners work out whether solar, a battery or both makes sense for them, then arrange a free quote with our installation partner and go through it with you in plain English. Swancomm doesn't install anything. Our partner does the installation and contracts directly with you. See how it works.
Is your advice really free? How do you get paid?
Yes, it's free for you, whether or not you go ahead. When you go ahead, our installation partner pays Swancomm a referral fee.
Who installs my system, and who do I sign with?
Our installation partner, an independent business. They prepare your quote, sign the contract with you, install the system, lodge the rebate and connection paperwork and give you their workmanship warranty. The equipment warranties come from the manufacturers. We work with one installer only. If you'd like to compare, you're welcome to get other quotes yourself.
How does the federal battery rebate work?
Under the Cheaper Home Batteries Program, an eligible home battery earns small-scale technology certificates (STCs). Their value comes off the installer's price at the point of sale, so there is no form to fill in and no waiting for a refund. The battery has to be on the approved product list and installed with solar (new or existing) by a Solar Accreditation Australia (SAA) accredited installer. The number of certificates per kWh falls every January and July, so the discount gets smaller over time. See the full rebate details.
