Solar Panel Cost Calculator & Price Guide
Use our Solar Panel Cost Calculator & Price Guide to get a fast estimate for system pricing in Australia, whether you need a solar install calculator, a solar installation cost calculator, or a solar panel system cost calculator. Based on the live pricing settings, installed solar starts from around $1,000 per kW for Budget systems and goes up to $1,700 per kW for Premium systems, with battery add-ons priced separately in AUD.

Solar Panel Price Breakdown
Typical job based on 6.6 kW. Prices are supply-and-install midpoints — actual quotes will vary.
| Type | Cost per kW | Typical 6.6 kW job |
|---|---|---|
| Budget (Tier 1 value) | $1,000 | $6,600 |
| Mid (Tier 1 premium) | $1,200 | $7,920 |
| Premium | $1,700 | $11,220 |
What Affects Solar Panel Cost?
- System size (kW): The main driver of price is the size of the solar system, because this calculator prices panels per kW. A typical 6.6 kW system costs more than a smaller setup simply because there is more equipment and installation work involved.
- Panel and inverter tier: Your selected quality tier changes the per-kW rate. Budget systems are priced at $1,000 per kW, Mid systems at $1,200 per kW, and Premium systems at $1,700 per kW.
- Battery storage size: Adding battery storage increases the total cost on top of the panel system price. The configured add-ons are $7,500 for 5 kWh, $10,500 for 10 kWh, and $14,500 for a 13.5 kWh battery.
- Minimum job charge and estimate range: Where the calculated price is very low, a minimum job charge of $2,500 AUD applies. Displayed estimates also show a range of plus or minus 15% around the midpoint, which helps reflect typical variation in quoted pricing.
Solar Panel Cost - Frequently Asked Questions
A solar install calculator estimates price by multiplying your chosen system size by the tier rate per kW, then adding any battery cost. For example, a 6.6 kW Budget system is priced at $6,600 AUD, while a 6.6 kW Premium system is $11,220 AUD before any battery is added.
For a typical 6.6 kW system, the midpoint prices are $6,600 AUD for Budget, $7,920 AUD for Mid, and $11,220 AUD for Premium. Using the displayed estimate range of ±15%, that works out to about $5,610 to $7,590 for Budget, $6,732 to $9,108 for Mid, and $9,537 to $12,903 for Premium.
The calculator adds battery pricing on top of the solar system cost. For a 6.6 kW Mid system at $7,920 AUD, totals become $15,420 with a 5 kWh battery, $18,420 with a 10 kWh battery, or $22,420 with a 13.5 kWh battery.
A solar install cost calculator is useful for budgeting because it follows fixed live rates and shows an estimate range of ±15% around the midpoint. For example, if your calculated midpoint is $7,920 AUD, the displayed range would be approximately $6,732 to $9,108.
This solar panel system cost calculator estimate includes the base installed system price per kW and, if selected, a battery add-on. The panel rates are $1,000, $1,200, or $1,700 per kW depending on tier, and battery add-ons are $0, $7,500, $10,500, or $14,500 AUD.
Yes. If the maths for a very small system comes in below the minimum threshold, the displayed estimate uses a $2,500 AUD minimum job charge. This ensures very small jobs are not shown below the configured floor price.
