Solar System Sizes and Costs: What Size Do You Need?
Solar system sizing depends on your household electricity usage, roof space, and budget. The most popular residential system size in Australia is 6.6 kW — it hits the sweet spot between cost, output, and the typical inverter limit for single-phase homes.
| System Size | Cost (installed, after STCs) | Daily Output (avg) | Best For |
|---|---|---|---|
| 3 kW | $2,500–$4,500 | 10–14 kWh | Small household, 1–2 people, low daytime usage |
| 5 kW | $3,500–$6,000 | 17–23 kWh | Average household, 2–3 people |
| 6.6 kW | $4,000–$8,500 | 22–30 kWh | Most popular — suits 3–4 people, single-phase homes |
| 8 kW | $5,500–$9,000 | 28–36 kWh | Larger homes, pool pumps, home offices |
| 10 kW | $6,000–$12,000 | 35–45 kWh | High usage, EV charging, three-phase homes |
| 13 kW | $10,000–$16,000 | 45–58 kWh | Large homes, multiple EVs |
These prices include the federal STC rebate, which reduces the upfront cost by $2,000–$4,000 depending on system size and your location. The STC rebate shrinks each year because the deeming period drops by one year annually until the scheme ends in 2030, so prices effectively rise over time. Most installers factor the rebate into their quoted price.
Solar Battery Costs in Australia: Is Storage Worth It?
Adding a battery to your solar system lets you store excess daytime generation for use in the evening — but batteries remain the most expensive component of a solar setup. Whether battery storage makes financial sense depends on your electricity tariff, usage patterns, and how much you value blackout protection.
| Battery | Capacity | Cost (installed) | Warranty |
|---|---|---|---|
| Tesla Powerwall 3 | 13.5 kWh | $12,000–$17,000 | 10 years |
| BYD HVS / HVM | 5.1–22.1 kWh | $6,000–$18,000 | 10 years |
| Enphase IQ 5P | 5 kWh (modular) | $7,000–$9,000 | 15 years |
| Alpha ESS SMILE5 | 5.7–22.8 kWh | $6,500–$16,000 | 10 years |
| SolarEdge Home Battery | 9.7 kWh | $10,000–$14,000 | 10 years |
| Sungrow SBR | 9.6–25.6 kWh | $7,000–$15,000 | 10 years |
At current electricity prices, a solar battery typically pays for itself in 8–12 years — longer than the 3–5 year payback of solar panels alone. Batteries make the most financial sense if you're on a time-of-use tariff with expensive peak rates (30c+ per kWh), or if you want blackout protection. The federal Cheaper Home Batteries Program now takes around 30% off the upfront cost of an eligible battery, which materially improves the payback — and some states add stacking incentives on top. Without rebates, most households are better off maximising their solar panel system first.
Solar and Battery Rebates
Two federal rebates apply everywhere in Australia — the STC rebate on solar panels and the Cheaper Home Batteries Program on battery storage — and some states add their own incentives on top:
The main battery incentive is now the federal Cheaper Home Batteries Program — a national discount of around 30% on the upfront cost of an eligible home battery (5 kWh to 100 kWh), which your installer or retailer gives either as an upfront reduction or as a rebate after installation. The full discount applies to the first 14 kWh of usable capacity and tapers on larger batteries. The discount steps down gradually to 2030, so earlier installs capture more.
Some states and territories add stacking incentives on top (for example NSW's VPP battery incentive and the ACT's low-interest household energy loans), but these open, close, and change funding often — check your state's current offerings before committing. The older state battery rebates (Victoria's Solar Homes battery rebate, Queensland's Battery Booster, South Australia's Home Battery Scheme) have closed or been folded into the federal program.
State programs often carry income or property-value caps, so your installer should confirm what you actually qualify for and factor it into the quote. Both federal rebates are normally handled by your installer or retailer — the solar STC discount shows on your quote, and the battery discount comes either as an upfront reduction or as a rebate after installation — so you usually don't lodge a claim yourself.
What Affects Solar & Battery Costs in Australia
System size
6.6 kW suits most 3–4 bedroom Australian homes. Larger homes or those with electric vehicles may need 10 kW+ ($6,000–$12,000). Oversizing slightly is usually good value.
Panel quality
Standard panels ($4,000–$8,500 for 6.6 kW in Australia) use tier-1 brands like Jinko or Trina. Premium panels ($6,500–$10,500) use brands like SunPower, REC, or LG — offering better efficiency and longer warranties.
Battery storage
A 5 kWh battery adds $5,000–$9,000 in Australia. A 10–13 kWh battery adds $8,000–$15,000. Batteries make most financial sense if you have high evening electricity usage or time-of-use tariffs.
Roof type & orientation
North-facing roofs generate the most energy in Australia. Tile roofs are standard cost; tin/metal is slightly easier. Flat or complex roofs may need tilt frames, which add to the cost.
Inverter type
String inverters are standard and cheaper. Micro-inverters or optimisers cost more but perform better with shading or complex roof layouts.
Government rebates
Federal STCs (Small-scale Technology Certificates) reduce the upfront cost — already factored into most quoted prices. Check for any additional state rebates in your area.
