6.6kW Solar System
You’ve probably heard about 6.6kW solar systems — and there’s a reason they’re all over Aussie rooftops. For most homes, it’s kind of the go-to. Not too big, not too tiny — just right for trimming down those power bills.Typically, you’ll get 16 to 26 panels, depending on the wattage. It does take some roof space, but nothing over-the-top. Most standard houses have enough room.With good sun, you’re looking at roughly 20 to 27 kWh a day — enough to run daytime appliances like your fridge, TV, dishwasher, maybe even some aircon. That alone makes a dent in the bills.
If you’re just starting out with solar and don’t want to overcomplicate things, 6.6kW is a pretty safe and popular place to begin.

Why 6.6KW? – A sweet spot for Aussie households
A lot of Aussies find that 6.6KW solar system hits that sweet middle ground. It’s big enough to make a noticeable difference in your electricity bills, but not so huge that it breaks the bank or takes over your whole roof.
Now, technically, 6.6KW refers to the solar panel capacity, not the inverter. Most homes will get this paired with a 5KW inverter — which is often the max allowed for grid export in many areas (depending on your local DNSP).
And yeah, that little mismatch is actually deliberate. You “oversize” your panels a bit to squeeze more juice out during less-than-perfect conditions — cloudy mornings, winter afternoons, that sorta thing.
What can a 6.6KW solar system actually power?
A 6.6KW solar system will produce, on average, around 20–27 kWh per day, depending on where you live and the season. That’s enough to cover:
Fridge (24/7): 1–2 kWh/day
Washing machine (1 cycle/day): ~1 kWh
Dishwasher: 1–1.5 kWh
TV (3–4 hrs): 0.5 kWh
Lights & fans: 1–2 kWh
Aircon (moderate use): 2–4 kWh/hour
So yeah, it can handle the bulk of your home’s daytime needs, especially if you’re smart with usage. If you add a battery later, even better.
Average solar output – What to expect from 6.6KW
let’s get a little nerdy (just a little). Depending on your state, daily solar generation can vary:
| State | Avg Output (kWh/day) |
|---|---|
| QLD (Brisbane) | ~27–29 kWh |
| NSW (Sydney) | ~24–26 kWh |
| VIC (Melbourne) | ~20–23 kWh |
| SA (Adelaide) | ~25–27 kWh |
| WA (Perth) | ~27–30 kWh |
These numbers are based on north-facing panels, good sunlight, and minimal shading. Bad weather, poor panel tilt, or trees in the way? Yeah, those can knock your numbers down a bit.
Getting your system installed: What to expect
Before you go ahead and book an installer, there’s a few things you should know:
Panel direction matters. North-facing’s best, but east-west can work too (and helps catch morning/evening sun).
Inverter quality = peace of mind. Brands like Fronius, Sungrow, or SMA tend to last longer and give better efficiency.
Roof space? A 6.6KW system usually needs 16–18 panels, depending on wattage, so make sure your roof can take that.
Approval from your DNSP might be needed, especially if you’re feeding excess power back into the grid.
Hot tip: Always ask if the installer is CEC accredited — that’s the gold standard in Australia
How much does a 6.6KW solar system cost in Australia?
You might notice that prices for solar vary a lot. But for 6.6KW, you can expect base prices starting around A$3,999 — that’s without installation. Once you factor in install, total cost usually lands somewhere between A$5,000 and A$7,000, depending on:
Your location (regional areas may cost more)
Panel and inverter brands
Roof complexity
Installer experience
Whether any electrical upgrades are needed
Installation cost? That’s typically A$1,000–A$3,000, and in many cases, it’s bundled into the quote. Always check if the quote includes everything — panels, inverter, install, and grid connection — to avoid sneaky surprises.
Is 6.6KW right for you?
Now here’s the thing — 6.6KW isn’t a “one-size-fits-all” magic number.
It’s great if:
- You’ve got 3–5 people at home
- You work from home or use power during the day
- You want good ROI but aren’t ready for batteries yet
- You want to future-proof for EV charging or more appliances later
But maybe not ideal if:
- You live alone and barely use power
- Your roof space is limited
- You’re on a tight budget and can’t claim any rebates
Still, it’s a solid “middle-tier” setup that most Aussie families can get heaps of value from — especially if you run things like washing machines, dishwashers, and aircon during daylight.
