Either way, the 13KW solar system is one of those setups that’s not too small, not too massive — it hits a sweet spot for Aussies wanting to cut down their power bills in a serious way.
A lot of homeowners across Australia are now exploring solar beyond the typical 6.6KW or 10KW sizes. That’s where 13KW starts becoming a solid option, especially with battery storage getting more affordable.Let’s break it all down and see whether it’s the right fit for your roof — and your wallet.

Is a 13KW Solar System Right for Your Home?
Honestly, it’s not for everyone. If you’re living alone or in a tiny unit, this system will be overkill. But for a family of 4–6 with multiple appliances, ducted air conditioning, and maybe a home office or EV charger, 13KW makes sense.
You might notice that many Aussie homes now run more stuff during the day: dishwashers, pool pumps, laundry machines — even working-from-home setups that need solid power throughout the week. If that sounds like your household, this system can cover a good chunk of your daytime load.Who’s this size for? Usually bigger families — the kind with two fridges, laundry running daily, and air con going strong. Folks working from home love it too. If you’ve got an EV or thinking about getting a battery later, it just makes sense
How Much Power Does a 13KW System Generate in Australia?
Let’s talk real numbers. The actual power you get will depend on where you live. But on average, across most Aussie cities, a 13KW solar system can generate:
50 to 60 kWh per day (depending on sunlight, panel quality, etc.)
That’s around 18,000 to 22,000 kWh per year, which is a lot more than the average household usage — but again, homes are using more electricity now than ever.
City-by-City Example:
| Location | Avg Daily Output |
|---|---|
| Brisbane | ~60 kWh/day |
| Sydney | ~55 kWh/day |
| Melbourne | ~48 kWh/day |
| Perth | ~62 kWh/day |
| Adelaide | ~58 kWh/day |
Of course, weather, shading, roof angle — all of these can shift those numbers a bit.
What Components Are Included in a 13KW Solar Setup?
You’re not just getting panels — there’s more that goes into a proper solar system.
Typical 13KW Package Includes:
30–35 solar panels (370W to 440W each)
1 × 10KW or 2 × 5KW inverters
Mounting rails and brackets
Cabling and electrical hardware
Optional: battery storage (can be added later)
Wi-Fi monitoring (many inverters now offer this)
Brands like Fronius, Sungrow, and GoodWe are popular inverter choices in this range.
Price Guide for 13KW Solar Systems
The price can vary a bit depending on the brand of panels, inverter quality, and whether you’re getting a battery too.
System Cost:
Starts from around A$7,599 (for panels + inverter, no extras)
Higher-end systems (with premium brands) can go above A$10,000–12,000
Installation Cost:
Roughly A$1,000 to A$3,000 depending on:
Rooftop complexity
Location (rural installs often cost more)
Switchboard upgrades (if needed)
Government Rebates:
In most Australian states, homeowners and businesses are eligible for STCs (Small-scale Technology Certificates), which can lower the upfront cost by approximately $3,000–$5,000, depending on your location.
Some states or territories, such as SA and VIC, may also provide additional rebates or interest-free loan programs. It’s advisable to check your state government’s official website or consult a local solar installer for the most up-to-date incentives.
Rooftop Space and Installation Requirements
You’ll need a fair bit of roof space — around 60–75 square metres, depending on the wattage of each panel.
Few Things Installers Check:
Roof direction: North-facing is ideal in Australia
Shade levels: Trees, chimneys, nearby buildings
Roof pitch: Impacts how much sunlight you catch
Condition: If your roof is old or brittle, it might need reinforcing
Good installers will assess all this before quoting. Some even use aerial imagery to plan your panel layout.
Payback Period and ROI
This is where it gets interesting — many Aussies now see ROI in 4–6 years, especially if energy prices stay high (which they probably will).
Let’s say your 13KW system costs $9,500 total (after rebates). If it saves you $2,000/year in electricity, you break even in under 5 years.
If you install a battery, the payback might stretch to 8–10 years — but the independence is worth it for many.
Is Battery Storage Necessary with a 13KW System?
Not necessarily — but it’s becoming more common.
If you’re home during the day and can use solar as it’s being produced, a battery might not be urgent. But if most of your usage happens at night, or you want protection from blackouts, then a battery starts making sense.
Pros of Adding a Battery:
Use your solar at night
Reduce your grid reliance to near-zero
Can keep lights on during outages (depending on setup)
Common Battery Options:
| Battery Name | Capacity | Price (approx) |
|---|---|---|
| Tesla Powerwall 2 | 13.5 kWh | $11,700–$13,700 |
| Sungrow SBR | 9.6 – 19.2kWh | $8,000–$12,000 |
| BYD Battery Box | Modular | Varies |
You don’t need to install the battery right away — you can always make your system battery-ready and add it later.
What Do Aussies Say About Their 13KW Systems?
Talk to anyone who’s been running a 13KW solar setup for a while, and chances are, they’ll tell you it’s one of the best upgrades they’ve made. Many say their energy bills have dropped so much that they barely even think about them anymore.
One person shared how they run their pool pump, dishwasher, air con — and still manage to send energy back to the grid. That kind of performance gets people pretty happy, especially during summer months.
Sure, a few people felt the initial cost was a bit of a stretch, or that their roof just had enough space to fit the panels. But once everything’s up and running, most agree it’s been well worth it.
