Typical Melbourne solar prices (after rebates)
Prices vary with system size, panel and inverter brand, roof complexity and whether you add a battery. As an indicative guide for Melbourne homes in 2026, after the federal STC incentive is applied upfront:
- 6.6kW system — around $4,500–$6,500 installed. Suits smaller homes and modest daytime use.
- 10kW system — around $7,000–$10,000. A common size for family homes with an EV or battery in mind.
- 13.2kW system — around $9,000–$13,000. Larger homes with high usage.
- Add a battery — a solar-plus-battery package typically lands around $12,000–$18,000+, before the federal battery discount.
These are indicative ranges, not quotes. Your exact price depends on your roof and switchboard, which we confirm at a free on-site assessment before issuing an itemised fixed-price proposal. See our solar panels page for how we design systems.
What drives the price up or down
- System size (kW) — the single biggest factor. Bigger arrays cost more but usually deliver better value per kilowatt.
- Panel and inverter tier — Tier-1 gear from the Clean Energy Council approved lists costs more than budget hardware but lasts longer and keeps rebate eligibility.
- Roof type and access — tile vs metal, single vs multi-storey, and pitch all affect labour.
- Switchboard upgrades — older boards sometimes need work before solar; we identify this upfront so it's never a surprise.
- Battery — the biggest optional add-on. See our battery cost & payback guide.
Rebates that reduce the price
Two main incentives apply for eligible Melbourne homes: the federal STC discount, applied upfront at the point of sale, and the Victorian Solar Homes rebate of up to $1,400 (with an optional interest-free loan) for eligible owner-occupiers with a household income under $150,000. Eligibility rules change over time — our full 2026 Victorian rebates guide has the detail, and we confirm your eligibility before any proposal.
Payback period
A typical Melbourne solar system pays for itself in around 3–5 years, then generates largely free electricity for 20+ years. Adding a battery extends payback to roughly 7–9 years but adds evening savings and optional backup. Use our savings calculator for an estimate based on your own bill.
Frequently asked questions
Is solar still worth it in Melbourne in 2026?
For most owner-occupied homes, yes. Even with lower feed-in tariffs, using your own solar during the day (and storing it in a battery for the evening) typically delivers a 3–5 year payback on solar alone, followed by 20+ years of low-cost power.
How much does a 6.6kW solar system cost in Melbourne?
Indicatively around $4,500–$6,500 installed after the federal STC discount, depending on panel and inverter choice, roof type and any switchboard work. We confirm the exact price at a free assessment.
Do cheap solar deals actually save money?
Not always. Very low prices often mean budget hardware, undersized cabling or minimal after-sales support. We quote Tier-1 CEC-approved gear with an itemised fixed price so you can compare like for like.
