Here’s a rough guide to installed system costs in Australia:
| Household Size | Typical System | Installed Cost (approx.) |
|---|---|---|
| 1–2 people | 5–8 kW | $18,000 – $22,000 |
| 3 people | 10 kW | $28,000 – $30,000 |
| 4 people | 15 kW | $34,000 – $38,000 |
| 5+ people | 20 kW | $46,000 – $50,000 |
Prices are approximate and after rebates. System cost varies by location, equipment quality, and battery storage required.
Worth keeping in mind: connecting a rural property to the grid typically starts at $25,000. Figures of $60,000 to $100,000 are common. Against that, an off-grid system starts to look like the rational choice.
