Solar + Battery Savings in {{SUBURB}}, {{STATE}} {{POSTCODE}}
What would solar panels and a home battery actually cost — and save — for a typical household in {{SUBURB}} ({{POSTCODE}})? Here's the full worked example using 2026 {{STATE_NAME}} tariffs, the federal rebates, and a family-sized home using about 20 kWh a day.
The typical {{SUBURB}} bill
Canstar's May 2026 data shows the average {{STATE}} quarterly electricity bill at ${{AVG_BILL_Q}} — about ${{AVG_BILL_A}} a year. Our example household is a step above average at ~20 kWh a day (~$2,800 a year before solar), which is common for a family home with air-con and evening cooking. On the 2026–27 {{STATE}} benchmark tariff of {{TARIFF}}c/kWh with a typical flat feed-in tariff of {{FIT}}c/kWh, that breaks down as:
- 7,300 kWh a year × {{TARIFF}}c ≈ $[usage] in usage charges.
- ~{{SUPPLY_DAY}}c a day supply charge ≈ ${{SUPPLY_YEAR}} a year.
- Total: ~$[total] a year before solar.
{{LOCAL_NOTE}}
The recommended system: 6.6 kW solar + 10 kWh battery
For this usage profile, the sweet spot is a 6.6 kW solar system (about 15 modern 440W panels) paired with a 10 kWh home battery:
- A 6.6 kW system generates roughly 25.7 kWh a day (~9,400 kWh a year) in {{SUBURB}}'s solar zone.
- That covers the household's annual usage, with surplus to store.
- The battery lifts self-consumption from ~35% (solar only) to ~65% — catching daytime surplus for the evening peak.
Cost after rebates
| Item | Figure |
|---|---|
| 6.6 kW solar, installed (after STC discount) | $6,600 (6.6 × $1,000/kW) |
| 10 kWh battery, installed (before rebate) | $11,000 (10 × $1,100/kWh) |
| Federal Cheaper Home Batteries rebate | −$2,450 (10 × $245/kWh) |
| Total after rebates | $15,150 |
The solar STC rebate is baked into the $6,600 price: {{SUBURB}} sits in CER {{ZONE_NAME}}, so a 6.6 kW system installed in 2026 earns 6.6 × {{ZONE}} × 5 deeming years = {{STC_COUNT}} STCs, worth about ${{STC_VALUE}} at $38/STC. The battery rebate is the federal Cheaper Home Batteries Program at ~$245/kWh for the first 14 kWh. (Note: the battery rebate steps down on 1 January 2027, so a 2026 install captures the higher rate.)
Estimated savings and payback
With the battery storing ~65% of solar output for evening use:
- Self-consumed solar: ~6,107 kWh a year × {{TARIFF}}c avoided ≈ $[self-consumption saving].
- Exported surplus: ~3,288 kWh a year × {{FIT}}c feed-in ≈ $[export credit].
- Total estimated annual saving: ~${{ANNUAL_SAVING}}.
That gives a simple payback of about {{PAYBACK_YEARS}} years on the $15,150 outlay. Solar alone (no battery) would pay back in around 5 years but leave most evening usage on the grid.
Eligibility checklist for {{SUBURB}} households
- CEC-approved battery installed by a Solar Accreditation Australia accredited installer.
- Battery between 5 and 100 kWh nominal; the federal rebate covers the first 50 kWh of usable capacity.
- Paired with new or existing rooftop solar; grid-connected systems must be VPP-capable (joining a VPP is optional).
- One rebate per electricity meter; no income test.
