The numbers

A typical Perth household saves $1,500–$2,400 a year

Grid savings

Every kWh your battery covers is a kWh you do not buy from Synergy at peak. At 32¢/kWh on the A1 tariff, a 10kWh battery cycling daily saves roughly $1,182/year.

32¢

per kWh saved

Rebate stack

Federal STCs and the WA Battery Scheme together reduce your upfront cost by $3,000–$5,000. The exact amount depends on system size and postcode.

Clean Energy Council

3.7M homeswith rooftop solar in Australia

More per capita than any other country. WA leads in per-household generation, which makes battery storage well-suited to self-consumption.

WA's wholesale market regularly hits negative pricing during solar peaks. Batteries that shift household consumption into those windows capture the most value per kWh stored.

Before you ask

Questions we get asked

A typical 10–13 kWh system installs for $10,000–$14,000 after rebates. The main variables are battery capacity, whether a hybrid inverter swap is needed (add $2,000–$3,000 if you are retrofitting to existing solar), and installation complexity. Our calculator gives a closer figure once you enter your usage.

Two programs apply: Federal STCs (typically $3,000–$5,000 depending on battery size and timing) and the WA Battery Scheme ($130/kWh up to $1,300 for Synergy customers, 10 kWh maximum eligible capacity). Both stack. The WA scheme requires VPP enrolment.

Industry analysis and typical Perth configurations put payback at 6–9 years for a battery sized to your actual usage. Oversized batteries take longer. Most of the saving comes from self-consumption, using stored solar at night, rather than export credits.

Battery prices have stabilised after years of decline. Under the federal STC framework in force since 1 May 2026, batteries up to 14 kWh receive the full rebate factor, with reduced allocations at the 14–28 kWh and 28–50 kWh tiers. For most homeowners, if the system is sized to your usage, the economics work today. Right-sizing matters more than timing.

Yes. We compare CEC-approved batteries, inverters, and solar panels from hundreds of manufacturers. Installer matching covers panels only, a battery retrofit, or a full system with panels, inverter, and battery together.

It depends on your existing setup. With a standard solar inverter, you can either replace it with a hybrid inverter or add an AC-coupled battery that brings its own inverter. For a new solar + battery install, a hybrid inverter is usually the lowest-cost configuration. The guided matching tool works out which fits.
