How Much Do Solar Panels Cost in Melbourne 2026
If you're a Melbourne homeowner researching solar, the first thing you want to know is the number. A quality 6.6kW solar system in Melbourne costs roughly $5,000–$8,500 installed after the federal STC rebate and the Victorian Solar Homes Program discount of $1,400. That's a real, usable figure — not a teaser rate for the cheapest gear on the market, and not a premium installer's top-of-range quote.
Melbourne is a strong solar city, but it's not Sydney or Brisbane. With around 4.1 peak sun hours per day (compared to 5.0 in Brisbane and 4.7 in Sydney), your system will generate slightly less electricity year-round — which affects payback calculations. That doesn't make solar a bad decision here; it just means you should run the Melbourne-specific numbers rather than trusting a national average.

Key takeaways:
- A 6.6kW system in Melbourne costs $5,000–$8,500 after the federal STC rebate and VIC Solar Homes $1,400 rebate.
- The Victorian Solar Homes Program also offers an interest-free loan of up to $1,400 for eligible households.
- Melbourne averages 4.1 peak sun hours/day — lower than Brisbane or Sydney, so payback is typically 6–8 years (not the 4–5 years sometimes advertised nationally).
- VIC feed-in tariff is a minimum 4.9c/kWh for new systems from July 2025 — relatively low, so self-consumption matters more than exporting.
- Always use a CEC-accredited installer to qualify for rebates.

Melbourne solar cost table by system size {#solar-cost-table}
These price ranges reflect installed costs in Melbourne in 2026 using mid-to-premium tier equipment from CEC-accredited installers. They include GST and the federal STC rebate, and the "after VIC rebate" column assumes the additional $1,400 Victorian Solar Homes Program discount.
This is a price indication only. Your tradie will confirm the final price after assessing the job.
| System size | Typical panels | Before VIC rebate | After $1,400 VIC rebate | Est. annual savings |
|---|---|---|---|---|
| 6.6 kW | 16–18 panels | $6,400–$9,900 | $5,000–$8,500 | $1,100–$1,500 |
| 10 kW | 24–28 panels | $9,400–$13,400 | $8,000–$12,000 | $1,600–$2,200 |
| 13.2 kW | 30–36 panels | $11,400–$16,400 | $10,000–$15,000 | $2,000–$2,800 |
Methodology note: These ranges are based on estimates generated through Leadkit's solar savings calculator using current Victorian electricity rates and installer data, cross-referenced against the Solar Choice Price Index (May 2026). Leadkit's calculator is our own tool and the estimates are indicative; actual quotes from installers will vary.
Budget systems (no-name panels, entry-level string inverter) sit at the lower end of the "before rebate" range. Premium installs — think Enphase microinverters with SunPower or LG Neon panels — push toward the top. Most Melbourne homeowners land somewhere in the middle.
Victorian Solar Homes Program explained {#vic-solar-homes}
The Victorian Solar Homes Program is run by Solar Victoria and is the most significant state incentive available to Melbourne homeowners. As of 2026, it offers two complementary benefits:
1. Point-of-sale rebate — up to $1,400
This comes straight off the installer's invoice at the time of purchase. You don't wait for a cheque; the installer claims the rebate directly. It stacks on top of the federal STC (Small-scale Technology Certificate) discount, which is already built into the prices quoted by reputable installers.
2. Interest-free loan — up to $1,400
Eligible households can also access an interest-free loan of $1,400, repaid over four years. Combined with the rebate, that's $2,800 in total support — nearly halving the effective cost difference between a budget system and a quality mid-range one.
Eligibility (2026 criteria):
- Owner-occupied property (not rental or investment)
- Combined household taxable income under $210,000 per year
- Property value under $3 million
- Address has not previously received a Solar Homes rebate
- System installed by a Solar Victoria-registered installer
Application process:
You apply through the Solar Victoria website before installation. Approval is typically fast. Your installer must be registered with Solar Victoria — check the portal to verify before signing a contract.
Important: rebate availability can fluctuate. Solar Victoria periodically pauses new applications when the quota is reached. Check the portal for current availability before planning your timeline.
What affects solar cost in Melbourne {#cost-factors}
Peak sun hours and roof orientation
Melbourne receives approximately 4.1 peak sun hours per day on average — lower than Brisbane (5.0) and Sydney (4.7). This matters because solar output scales directly with sun hours; a 6.6kW system in Melbourne will generate roughly 15–20% less electricity annually than the same system in Brisbane.
For Melbourne homeowners, a north-facing roof at 15–30° tilt maximises output. East or west orientations reduce annual generation by 10–15%. A solar installer should provide a shading analysis, especially for inner-city suburbs where neighbouring buildings cast shadows in winter months.
STC zones and rebate value
STCs — Small-scale Technology Certificates — are the mechanism behind the federal solar rebate. The number of STCs a system generates depends on the Clean Energy Regulator's zone rating for your location. Melbourne sits in STC Zone 4, which delivers slightly fewer certificates than Brisbane (Zone 3) or Darwin. The practical impact: Melbourne STC rebates are a few hundred dollars less than for the same system up north, but still substantial — around $2,000–$3,000 for a 6.6kW system at current certificate spot prices.
STCs are phased down annually under the federal government's schedule, reducing by one-fifteenth each year until 2030. Installing sooner locks in a higher rebate.
Inverter type: string inverter vs microinverter
A string inverter connects all your panels in series. It's cheaper and reliable for unshaded, same-direction roofs. If one panel underperforms (shade, soiling, angle), the whole string is affected.
Microinverters (like Enphase) attach to each panel individually — each panel operates independently. They cost $1,500–$3,000 more for a typical 6.6kW system but perform better on partially shaded roofs, give panel-level monitoring, and tend to suit the varied roof configurations common in Melbourne's older suburbs.
SolarEdge uses a hybrid approach — optimisers on each panel with a central inverter — and is a popular middle-ground for Melbourne installs.
Export limiting
AusNet Services (which covers much of Melbourne's outer east and north) and United Energy apply export limiting in certain areas — capping how much solar you can push back to the grid, sometimes as low as 1.5kW. This reduces the value of a large system if you're not home during the day to consume the generation. Ask your installer to check your network zone before sizing the system.
Panel brand and warranty terms
Tier 1 panels (SunPower, LG Neon, REC) carry 25-year product and performance warranties. Mid-tier (Jinko, LONGi, Canadian Solar) offer strong value. Budget panels carry higher long-term replacement risk. For a 25-year asset, paying an extra $600–$1,000 for a known brand is usually worth it.
Melbourne payback period — worked example {#payback-period}
Scenario: 6.6kW system, mid-range equipment (Jinko panels, Fronius inverter), north-facing roof in Ringwood, Melbourne.
- System cost after STC rebate: $7,000
- Less Victorian Solar Homes rebate: −$1,400
- Net cost: $5,600
- Daily generation at 4.1 peak sun hours: ~27 kWh/day
- Self-consumption rate (household home during day): ~35% = ~9.5 kWh/day consumed directly
- Exported to grid: ~17.5 kWh/day at VIC minimum feed-in tariff 4.9c/kWh = $0.86/day
- Grid electricity avoided: ~9.5 kWh/day at ~30c/kWh = $2.85/day
- Combined daily benefit: ~$3.71/day → ~$1,355/year
- Estimated payback: 5,600 ÷ 1,355 ≈ 4.1 years (optimistic — assumes consistent self-consumption)
In practice, with Melbourne's variable weather and typical household patterns, most homeowners see a 6–8 year payback for a quality 6.6kW system. The 4–5 year figures sometimes quoted are based on higher self-consumption, better sun-hour assumptions, or higher electricity tariffs than many households actually face.
Use Leadkit's solar savings calculator to run your own numbers with your actual bill and daily usage pattern.
Also worth modelling: pairing solar with a battery. If you generate plenty but export most of it at 4.9c/kWh, a battery lets you use that electricity yourself at 30c/kWh value instead. Check Leadkit's battery payback calculator to see whether battery storage stacks up for your situation.
Melbourne vs Sydney vs Brisbane solar comparison {#city-comparison}
| Factor | Melbourne | Sydney | Brisbane |
|---|---|---|---|
| Peak sun hours/day | 4.1 | 4.7 | 5.0 |
| 6.6kW annual generation (est.) | ~9,000 kWh | ~10,300 kWh | ~11,000 kWh |
| Federal STC zone | Zone 4 | Zone 3 | Zone 3 |
| State rebate | $1,400 VIC Solar Homes | No state rebate | No state rebate |
| Feed-in tariff (min.) | 4.9c/kWh (from Jul 2025) | ~2–6c/kWh (retailer-set) | ~6–10c/kWh (retailer-set) |
| Typical 6.6kW payback | 6–8 years | 5–7 years | 4–6 years |
| Network export limiting | Yes (some zones) | Yes (some zones) | Less common |
Melbourne's lower sun hours and low feed-in tariff mean the economics are more sensitive to self-consumption than in Queensland. The VIC Solar Homes rebate partly compensates for the lack of a state feed-in bonus — especially if you qualify for the loan as well.

Best panel and inverter brands used by Melbourne installers {#brands}
Melbourne's installer market is competitive. The brands you'll most commonly see quoted by reputable CEC-accredited solar installers in Victoria:
Solar panels:
- SunPower Maxeon — highest efficiency available (~22%+), 40-year warranty, premium price
- LG Neon — LG exited manufacturing but existing stock with strong warranties remains available
- REC Group — Norwegian-engineered, excellent build quality, popular with quality-focused installers
- Jinko Solar / LONGi — Tier 1 Chinese manufacturers; strong value, widely used by mid-market installers
- Canadian Solar — reliable Tier 1, competitive pricing
Inverters:
- Fronius (Austria) — widely regarded as the benchmark for string inverters in Australia; strong local support network
- SolarEdge — string inverter with panel-level optimisers; good for partly shaded or multi-orientation roofs
- Enphase — microinverter system; best for complex roofs, premium price, excellent monitoring
- SMA — German-engineered string inverter; reliable, popular with commercial and larger residential installs
- Growatt / Sungrow — budget-to-mid-range options; functional but with less robust Australian support
The Clean Energy Council (CEC) maintains an approved product list. Only CEC-approved panels and inverters qualify for the federal STC rebate and Victorian Solar Homes Program. Always verify your installer uses listed products.
How to get quotes and use the calculator {#get-quotes}
Getting multiple quotes is essential for Melbourne solar — prices vary by $1,500–$3,000 between installers for equivalent equipment. Here's the process:
- Run a savings estimate first. Use Leadkit's solar savings calculator to get a Melbourne-specific ballpark before talking to anyone. It uses Victorian electricity rates so the numbers are relevant to your situation.
- Get at least three quotes. All should specify: panel brand and model, inverter brand and model, total kW capacity, number of panels, installation warranty, product warranty terms.
- Check installer accreditation. Your installer must be CEC-accredited and Solar Victoria-registered for rebate eligibility. Both can be verified on the respective organisation's websites.
- Apply for the Solar Homes rebate before installation. Don't sign a contract until you have Solar Victoria approval — the rebate must be pre-approved.
- Ask about export limiting. Your installer should check AusNet Services or your local DNSP zone to confirm whether export limiting applies at your address.

Across the solar quotes generated through Leadkit's platform, the labour and installation component consistently accounts for 20–30% of the total system cost — a figure homeowners regularly underestimate when comparing panel-price-only advertising.
FAQ {#faq}
Q: How much does a 6.6kW solar system cost in Melbourne in 2026?
A: A 6.6kW solar system in Melbourne costs roughly $6,400–$9,900 installed before any state rebate, and $5,000–$8,500 after the $1,400 Victorian Solar Homes Program rebate. The federal STC discount is already included in quotes from reputable installers. Budget systems sit toward the lower end; premium panels and inverters (SunPower, Enphase) push toward the top. This is a price indication only — your installer will confirm the final price after a site assessment.
Q: Is it worth getting solar panels in Melbourne given the lower sun hours?
A: Yes, for most owner-occupiers — but the calculation is different to Brisbane or Sydney. Melbourne's 4.1 peak sun hours per day means lower annual generation than further north. The VIC Solar Homes rebate ($1,400) helps bridge the gap, and electricity prices in Victoria (around 28–35c/kWh) are high enough that avoided grid consumption still drives good savings. The key is maximising self-consumption rather than relying on feed-in tariff income, since VIC's minimum FiT is only 4.9c/kWh.
Q: What solar rebates are available in Victoria in 2026?
A: Two layers of rebate apply. First, the federal STC rebate — worth around $2,000–$3,000 for a 6.6kW system in Melbourne — is applied at point of sale by your installer. Second, the Victorian Solar Homes Program offers up to $1,400 off the installation cost, plus an optional interest-free loan of $1,400. To access the state rebate, you must own and occupy the property, have a combined household income under $210,000, and use a Solar Victoria-registered installer. Check Solar Victoria for current availability.
Q: How long does it take for solar panels to pay for themselves in Melbourne?
A: For a quality 6.6kW system installed at around $5,600–$7,000 after rebates, a realistic Melbourne payback period is 6–8 years. That's longer than the 4–5 years sometimes cited — those figures tend to assume high self-consumption, better sun hours, or higher feed-in rates than most Melbourne households achieve. A household that uses a lot of power during the day (working from home, pool pump, EV charging) will see a faster payback than one that is mostly empty during peak generation hours (10am–2pm).
Q: What is the feed-in tariff in Victoria in 2026?
A: The minimum feed-in tariff (FiT) for new solar systems in Victoria is 4.9c/kWh, set by the Essential Services Commission from July 2025. This is a floor — some retailers offer higher rates, so it's worth comparing retailer offers once your system is installed. The low FiT reinforces the importance of self-consumption: every kilowatt-hour you use yourself saves you ~30c, versus earning just 4.9c by exporting it.
Q: Do I need council approval to install solar panels in Melbourne?
A: In most cases, no — residential rooftop solar in Victoria is generally exempt from planning permits as long as the system doesn't exceed certain size and height thresholds. However, heritage overlays, some strata properties, and commercial-scale systems may require approval. Check with your local council and your installer. All grid-connected systems still require a licensed electrical contractor and a Certificate of Electrical Safety lodged with Energy Safe Victoria.
