If you’re comparing quotes for solar panels in Melbourne, the price range you’ll see can feel wide and confusing. The honest answer is that cost depends on system size, panel brand, inverter type, and your roof, but there are clear patterns worth knowing before you request a quote.
What drives the price of a solar system
Three things move the number most: the size of the system in kW, the quality of the panels and inverter, and how straightforward your roof is to install on. A single storey tiled roof with good northern exposure is cheaper to install than a two storey home with a complex roofline.
Typical system sizes for Melbourne homes
Most Victorian households land on one of a few common sizes depending on their electricity usage:
- 6.6kW, the most popular choice for family homes, covering around 8,500 kWh a year. See our 6.6kW Solar System package.
- 10kW, suited to larger homes, pools, or households planning to add an EV charger. See our 10kW Solar System package.
Bigger systems cost more upfront but bring the price per watt down, so it’s worth comparing your options against your actual usage rather than just your budget.
Quick Tip
Always ask your installer for the price after rebates, not the full retail price. The after-rebate figure is the one that actually matters for comparing quotes.
Government rebates reduce the real cost
Victorian rebates and federal Small-scale Technology Certificates, known as STCs, are applied as a discount at the point of installation, not as a rebate you claim later. Read our full Victoria Solar Rebate guide for eligibility details, or check your estimate with the STC Calculator.
Why the cheapest quote isn’t always the best deal
A noticeably cheap quote is usually cheap for a reason: lower tier panels, a smaller inverter than the system needs, or an installer cutting corners on mounting and wiring. Tier-1 panels with a 25 year warranty cost more per watt but protect you from replacement costs and performance drop off years down the track.
