If you’ve got a few ACs, a big fridge, maybe an EV charging out front, or you’re running a home office full-time… yeah, you might actually need it.In this blog, we’ll break it down — how much energy it gives, what it costs, and whether it’s a smart move for your situation

How much energy will a 30kW solar system produce?
The amount of energy a 30kW solar system will produce really depends on a few key things — like where you live, how much sun you get, which way your panels are facing, and whether there’s any shade falling on them. Even the temperature can impact how well they perform.
On average, across different Aussie cities, you can expect somewhere between 110kWh to 150kWh per day. That’s a yearly average — some days will be more, some less.
30kW Solar System Energy Output
| City | Estimated Daily Output (kWh) |
|---|---|
| Brisbane | 120 kWh/day |
| Sydney | 115 kWh/day |
| Canberra | 115 kWh/day |
| Melbourne | 110 kWh/day |
| Hobart | 100 kWh/day |
| Adelaide | 120 kWh/day |
| Perth | 125 kWh/day |
| Darwin | 125 kWh/day |
Who Usually Installs 30kW Systems – Businesses or Homes?
Traditionally, 30kW solar systems were reserved for commercial setups — think schools, office buildings, warehouses, or workshops. These systems were ideal for handling consistent, high daytime energy usage across large operations.
But that’s starting to shift. With more Australians working from home, driving EVs, and running energy-hungry appliances throughout the day, some large households are now also installing 30kW systems. It’s no longer just for businesses — high-usage homes are entering the game too.
How Much Does a 30kW Solar System Cost in Australia?
If you’re thinking about going for a 30kW solar setup in Australia, the system itself usually starts from around AUD $12,599. But that’s just the base. Once you factor in installation, which can range between $1,000 to $3,000 depending on your roof type, location, and who’s doing the install — you’re realistically looking at a total price between $13,500 and $15,500 for a solid quality setup.
Now, if you’re eyeing premium solar panels or thinking of adding a battery, the cost can creep up a fair bit. But here’s the good news — if you’re eligible for STCs (Small-scale Technology Certificates), you could slash a chunk off that upfront cost. So the final price might not be as scary as it looks
Real-World Benefits of a 30kW Solar Setup
A 30kW solar system isn’t just about size — it’s about real, measurable value. Whether you’re running a large home, managing a growing business, or powering electric vehicles, this system offers reliable performance and strong long-term returns.
Here’s what you get:
More energy, more flexibility – Over 100kWh of daily output covers all major appliances
Massive bill savings – Slash your power bill by $400–$700 per month
Fast return on investment – Many systems pay for themselves within 4–5 years
Lower carbon footprint – Great for going green and energy independence
Protection from rising grid prices – Lock in your energy costs for years to come
Rebates & Incentives Available in Australia
Australia still offers solid solar rebates in 2025. For systems under 100kW (like a 30kW), you’re eligible for:
- STCs (Small-scale Technology Certificates)
These can knock $3,000–$4,000 off your upfront price depending on your location. And if you’re in Victoria, South Australia, or ACT, there may be additional local rebates for commercial or home installations. It’s definitely worth checking your state’s solar rebate site before you install
Is a 30kW Solar System Right for You?
A 30kW solar system might sound massive — and to be fair, it kind of is. But that doesn’t mean it’s overkill. More and more Australians are finding this system size practical, especially those who run home-based businesses, charge electric vehicles, or have large families with high daily power use. With multiple appliances running throughout the day, it offers the flexibility and backup they need.
This system size is also well-suited for small commercial setups, including workshops, garages, schools, childcare centres, hospitality venues, and retail stores — offering consistent energy output and long-term savings.
