A 10kW solar system is the sweet spot for bigger households and higher power users enough capacity to run ducted air conditioning, a pool, or an EV largely on your own solar, while offering the best value per watt of any size we install. At SolarAide this is the Family Saver package, our top seller across Melbourne and Victoria.
What a 10kW solar system produces
A 10kW system in Melbourne generates around 40 kWh on a good day, or roughly 13,000–15,000 kWh a year. That’s well above the average home’s usage, which means it covers your daytime power and leaves a healthy surplus either exported for a feed-in credit or, better, stored in a battery for the evening.
It uses about 23 panels and needs roughly 42 m² of roof. Because 10kW exceeds the single-phase 5kW inverter limit on many networks, it’s often installed with a larger or hybrid inverter and may suit homes with three-phase power we confirm what your property supports during the assessment.
Who a 10kW system suits
Larger households
Best for 3–5 bedroom homes using around 40 kWh a day.
High-draw appliances
Comfortably runs ducted air-con, a pool pump, and electric hot water.
EV-ready
Enough surplus to charge an electric car on solar rather than the grid.
Battery-ready hybrid
A hybrid inverter option makes adding storage straightforward.
What’s included with the SolarAide Family Saver
Tier-1 panels with a 25-year product warranty, your choice of a string or battery-ready hybrid inverter (10-year warranty), the site assessment, Solar Victoria rebate paperwork, grid application and meter, monitoring app, and interest-free finance options all standard.
How much does a 10kW system cost?
After rebates, quality 10kW systems in Victoria typically run from around $7,000–$12,000 depending on panels, inverter and roof complexity. As with all our systems, SolarAide confirms your exact price on a call because a flat sticker price can’t account for your roof, usage and rebate eligibility.
Is 10kW worth it over 6.6kW?
If your quarterly bill is over about $500, you run air conditioning or a pool, or you have (or plan to get) an EV, then yes, the extra capacity of a 10kW system usually pays for itself through greater self-consumption and a bigger surplus to store. If you’re a lighter user under ~25 kWh a day, a 6.6kW system may give a better balance of cost and savings. The honest answer depends on your actual usage, which is exactly what we check before recommending a size.

How much does a 10kW system produce daily?

Do I need three-phase power for 10kW?
Not always, but a 10kW system exceeds the common single-phase 5kW inverter limit, so it’s often installed with a larger/hybrid inverter or on three-phase supply. We confirm what your home supports.
What size battery pairs with a 10kW system?
A 10kW system generates enough daily surplus to charge a 10–15 kWh battery on most Melbourne days, including typical winter days.
