Roof Complexity
Multi-storey homes, tile roofs, or steep pitches add labour. A straightforward single-storey Colorbond roof keeps costs at the lower end of the range.

2026 Pricing · STC Rebates Included
What solar panels actually cost in 2026
Most Australian homeowners pay between $900 and $1,250 per kW after the federal STC rebate. Below are real 2026 price ranges, what drives them, and how Solar Chief packages compare.
| System Size | Typical Cost (after STC) | Cost per kW | Best For | Bill Reduction |
|---|---|---|---|---|
| 6.6 kW | $4,500 – $7,000 | $680 – $1,060 | Small to medium (2–3 beds) | 50–70% |
| 10 kW | $8,000 – $12,000 | $800 – $1,200 | Medium to large (3–4 beds) | 70–85% |
| 13.3 kW | $9,500 – $14,000 | $715 – $1,050 | Large homes / pool / EV | 80–95% |
STC rebate already applied: The prices above reflect the point-of-sale STC discount most installers apply. Without it, costs would be roughly 20–35% higher. Solar Chief package pricing is shown after STC rebate.
What affects the price
Two identical-sized systems can differ by $2,000 or more. Here are the four main drivers.
Panel & Inverter Brand
Tier 1 panels (JA Solar, Jinko, Canadian Solar) cost more than budget panels but carry longer warranties and better degradation rates. Premium inverters add $400–$1,200.
STC Rebate Value
The federal STC rebate reduces upfront cost by roughly $1,500–$2,500 on a 6.6kW system. Solar Chief applies this at point of sale — the prices you see are already discounted.
Meter & Electrical Work
Older switchboards, 3-phase upgrades, or meter relocations add $300–$1,500. We inspect this during your free site assessment.
Storage Add-On
Battery storage costs in 2026
Adding a battery to your solar system typically adds $8,000–$17,000 to the total cost. A mid-range 10–13kWh battery installed usually falls around $10,000–$14,000.
The NSW Government offers a zero-interest loan of up to $15,000 for eligible households combining solar and battery — making the total package far more accessible.

Common cost questions
What is the average cost per kW for solar in Australia in 2026?
After STC rebates, most residential systems in 2026 cost between $900 and $1,250 per kW installed. A 6.6kW system typically lands around $5,000–$7,000, and a 10kW system around $8,000–$12,000.
Does the STC rebate apply automatically?
Yes. For eligible systems, the installer claims STCs and passes the value to you as a point-of-sale discount. The prices shown on Solar Chief packages already include this rebate.
How much does adding a battery increase the total cost?
Battery storage typically adds $8,000–$17,000 depending on capacity and brand. A mid-range 10–13kWh battery usually falls around $10,000–$14,000 installed.
Why is a 10kW system cheaper per kW than a 6.6kW?
Larger systems benefit from economies of scale. The fixed costs (scaffolding, travel, labour, metering) are spread across more panels, so cost per kW drops slightly as system size increases.
What is the payback period for a solar system?
Most Australian households see payback in 3 to 5 years depending on system size, electricity rates, self-consumption, and feed-in tariffs. Larger systems with batteries can stretch to 5–7 years but offer greater long-term savings.
Does Solar Chief include everything in the quoted price?
Yes. Our package pricing includes panels, inverter, installation, STC rebate, CEC-accredited labour, and standard electrical work. We flag any non-standard extras (meter upgrades, long cable runs) during your free assessment before you commit.
