Melbourne, Victoria

Melbourne has lower solar irradiance than most Australian capitals — but that doesn't mean solar isn't worth it. With electricity prices above 30c/kWh and generous Victorian solar rebates, Melbourne households still see strong returns. The key is getting the right system size for your actual usage.

How Much Can Solar Save You in Melbourne?

The average Melbourne household uses around 18–28 kWh per day and pays approximately 5c/kWh. At those rates, a properly sized solar system can eliminate 400–80% of your electricity bill — saving $2,200 or more per year.

But averages are misleading. A household that runs ducted air-conditioning will have very different savings to a household on a single-phase connection. That's why SolarBill reads your actual electricity bill — so your recommendation is based on your real usage, not a guess.

Most Common System Size in Melbourne
The most popular system size for Melbourne households is 10kW — large enough to cover most daytime usage while remaining cost-effective. Higher-usage households often benefit from a 10–16.6kW system.
Battery Storage in Melbourne
A 10kWh battery in Melbourne typically covers evening usage until around midnight. A 25.6kWh battery provides overnight coverage for most households. VIC feed-in rates are relatively low, making self-consumption via battery more valuable than exporting.

Solar in Melbourne — What You Need to Know

Melbourne's variable weather means spring and autumn are the highest-performing seasons — not summer. Winter is the weakest performer with only 2.8 peak sun hours in June. A battery becomes more valuable in Melbourne than in sunnier cities because you can store autumn and spring generation for winter evenings.

STC Rebate for Melbourne
Melbourne sits in STC Zone 4. The STC rebate for a 10kW system in Melbourne is currently worth approximately $3,200–$4,000 depending on the current STC price — deducted from your installation cost upfront.
Peak Sun Hours in Melbourne
Melbourne receives an average of 4.1 peak sun hours per day annually. Summer peaks at around 4.9 hours and winter drops to around 2.9 hours. SolarBill uses your actual location for all calculations.
