How is the Federal Battery Rebate applied to a quote?

The rebate is applied as an up-front discount based on usable capacity and the current tiered STC structure: the first 14 kWh earns the full factor, 14 to 28 kWh about 60 percent, and 28 to 50 kWh about 15 percent. Multiply the resulting STCs by the current STC price for the dollar value.

How to Quote a Home Battery (Australian Guide)

Q: How do you size a home battery?

Size a home battery to the energy the household uses in the evening and overnight, and to how much solar it exports during the day. The goal is to store surplus solar and shift it to peak times, not simply to fit the largest battery available.

Q: Is a battery worth it for the customer?

It depends on their tariff, solar export and usage pattern. A customer on a high peak rate with lots of evening usage and surplus daytime solar benefits most. An honest quote shows a realistic payback rather than an inflated one, which protects your reputation.

Battery enquiries are booming thanks to the Federal Battery Rebate. Here's how to quote one well: size it to real usage, apply the tiered rebate correctly, model solar-plus-storage savings, and present a payback the customer actually believes.

Four steps to an honest battery quote

Look at when the household actually uses power and how much solar it exports during the day. A battery earns its keep by storing surplus solar and releasing it in the evening peak, so this picture drives everything else. Interval (NEM12) data makes this precise.

Size to evening and overnight usage plus available solar export, not to the biggest unit on the shelf. Oversizing inflates the price and lengthens payback; right-sizing wins trust and the job.

Apply the Cheaper Home Batteries Program rebate on the current tiered STC structure: the first 14 kWh of usable capacity earns the full factor, 14–28 kWh about 60%, and 28–50 kWh about 15%. Because the factor steps down over time and the STC price moves, always use the current numbers.

Project solar-plus-storage savings on the customer's real tariff, including time-of-use, and present an honest payback. A realistic figure you can defend beats an inflated one that creates an unhappy customer later.

Eligibility reminder: the rebate applies to batteries roughly 5–100 kWh paired with solar, installed by a Solar Accreditation Australia certified installer using a Clean Energy Council approved battery. STCs are created on the first 50 kWh of usable capacity.
