A 10kW solar system in Melbourne produces around 36 kWh a day on average, or roughly 13,000 kWh a year. It is built for larger homes with high energy use, such as ducted air conditioning, a pool, home offices or an electric vehicle, and for small commercial sites.
Silicon Solar designs 10kW systems to suit your supply. Many are best installed on a three phase connection, and we check your switchboard and your network’s export rules before quoting, so there are no surprises.
10kW Solar System at a Glance
| Specification | 10kW Solar System |
|---|---|
| Panels | Around 21 to 23 panels at 440W to 475W each |
| Inverter | 10kW inverter, usually three phase (hybrid options available) |
| Roof space needed | About 45 to 50 square metres of unshaded roof |
| Average daily output in Melbourne | About 36 kWh |
| Estimated yearly output | About 13,000 kWh |
| Best suited to | Large homes, high daytime use, EV owners, small businesses |
| Warranties | 25 year panel product, 10 year inverter, 10 year workmanship |
Output figures are estimates based on Melbourne’s average solar exposure of roughly 3.6 kWh per kW of panels per day. Real generation depends on roof direction, tilt, shading and season, and is typically about half the average in mid-winter.

Who Needs a 10kW Solar System?
A 10kW system makes sense when your household uses a lot of electricity during the day or plans to electrify. It typically suits:
- Large families and homes with ducted reverse cycle air conditioning
- Properties with a pool, spa or electric hot water
- Electric vehicle owners who charge at home during the day
- Home businesses and small commercial premises
Single or three phase? Most Victorian networks cap single phase solar exports at around 5kW, so a 10kW system usually performs best on a three phase supply. If your home is single phase we will explain your options, including export limiting or adding a battery.
Getting the Most from a 10kW Solar System
Bigger systems pay off fastest when you use the energy yourself. With around 36 kWh a day available, you can run heavy loads on solar instead of grid power.
- Charge your EV during daylight hours
- Heat or cool the home on sunny afternoons
- Switch to a heat pump or electric hot water on a solar timer
- Pair the system with a battery to cover evening use
A 10kW system is also an ideal foundation for a large hybrid solar and battery setup.

Frequently Asked Questions
About 36 kWh per day on average, or roughly 13,000 kWh per year, depending on roof direction, tilt and shading.
Not always, but it is often recommended. Most Victorian networks limit single phase exports to around 5kW, so a 10kW system usually works best on three phase. We check your supply before quoting.
Around 21 to 23 panels using 440W to 475W modules, needing about 45 to 50 square metres of roof.
It is worth it for homes with high daytime use, such as ducted air conditioning, a pool or an EV. For moderate use, a 6.6kW system is usually better value.
Yes. A hybrid inverter lets you add a large battery now or later, so surplus solar powers your home in the evening.
Panels carry a 25 year product warranty, the inverter carries a 10 year warranty and our workmanship is covered for 10 years.
