30% off your battery.
Know what you're saving on top.
The Cheaper Home Batteries Program makes now a great time to go solar and battery. Before you sign, get an independent valuation built on your actual half-hourly usage so you know your real payback, not your installer's best guess.

Before you sign anything, know your real payback period, your actual savings, and whether the quote you've been given stacks up.
The Subsidy Trap
The Cheaper Home Batteries Program is genuine good news. From 1 July 2025, Australian households receive around 30% off the upfront cost of an eligible battery system connected to rooftop solar. That is real money. But a 30% discount on hardware is not the same as a 30% improvement in your financial return. Many homeowners who receive a promising installer quote find that real-world payback looks very different once the system is running.
“The average Australian homeowner quoted a 3-year payback receives a real payback of 4 to 8 years or more.”
A National Scheme Worth Knowing
The Cheaper Home Batteries Program funds approximately $311 per usable kWh of battery installed, delivered as a discount off your upfront price. No vouchers and no waiting. The discount is applied directly by your installer at the point of sale.
Your Payback Is Personal
A 30% upfront saving does not guarantee a fast return. Real payback periods for Australian homeowners typically range from 4 to 8 years depending on household usage, local tariff structure, battery sizing, and solar generation. Installer quotes often use industry averages rather than your actual consumption data.
Why the Numbers Don't Add Up
Installer payback estimates are typically back-of-envelope calculations. They apply a single average daily consumption figure against a flat assumed export rate. They do not model your actual half-hourly load shape, your morning and evening peaks, your solar generation curve, or how a battery dispatch algorithm behaves under your tariff structure. A household that uses most of its power while the sun is shining saves far less from a battery than one with heavy evening demand. Our model runs 17,520 interval calculations against your real data. That is the difference between a generic estimate and a number you can actually trust.
What's Included
A fixed-fee, independent Valuation Report delivered within 48 hours. No sales pitch and no hidden agenda.
Quote Sanity Check
We verify the recommended battery size against your actual load profile to confirm it matches your real usage patterns.
Real Financial Modelling
We calculate your genuine NPV, IRR, and payback period using your interval data, not industry averages or manufacturer assumptions.
Tariff Optimisation
We model whether switching to a battery-friendly or VPP-ready tariff improves your return on top of the federal subsidy.
Plain-English Verdict
You receive a clear recommendation: proceed with confidence, negotiate on price, or reconsider the system size.

Why Your Data Changes Everything
Most online battery calculators use state-wide household averages. We use your half-hourly interval data, up to 17,520 readings across the year, so the model reflects your actual morning peaks, evening draw, weekend patterns, and solar generation profile.
The result is a financial projection accurate to your home, not a generic estimate that may be off by thousands of dollars.
How to Get Your Interval Data
- 1Log in to your electricity retailer’s online portal or app.
- 2Look for a section called Usage Data, Energy Data Download, or similar.
- 3Download the CSV export of your half-hourly consumption. Ideally select the past 12 months for the most accurate model.
- 4If you cannot find it, contact your retailer and ask for your NMI interval data in CSV format.
Most Australian retailers provide this data free of charge. It is your data.
Built by people who have seen it from the other side.
The BuyerSideEnergy team comes from Australia's large-scale energy industry. Before advising homeowners, we spent years modelling the economics of utility-scale battery, solar, and wind assets for major network operators and energy retailers across the NEM. We have seen firsthand how financial models get built, where assumptions get stretched, and what a rigorous interval-level analysis actually looks like. That experience is what we now bring to every Valuation Report.
