13kW Solar System quick facts
Estimated output
About 47–55 kWh/day
Annual-average guide across our service capitals
Indicative panels
About 28–30
Based on typical 440–475W panels
Planning roof area
About 56–66 m²
Final layout depends on the selected panel and roof
Design
Detailed assessment
Roof, supply and connection all need checking
Household fit
For properties with a clear use for the extra energy
This size is most useful where high daytime consumption, EV charging or storage can make use of the generation. We model the property first so roof space and connection constraints are understood early.
- Large homes with several major electric loads
- Households moving transport and heating to electricity
- Properties planning meaningful battery capacity

What is included
A complete, clearly scoped installation
The final equipment is listed in your quote, so you know what is being designed and installed.
Approved solar panels
Panels selected from the Clean Energy Council approved-product list for the final design.
Inverter and monitoring
A compatible inverter plus app-based monitoring, with the exact model confirmed in your quote.
Mounting and electrical work
Roof mounting, cabling, safety equipment and compliant electrical installation included in scope.
Design, approvals and handover
System design, required connection paperwork, commissioning and monitoring setup.
Roof fit
A large array needs careful roof planning
At this size, shade, roof-face balance, fire and access clearances, structural condition and cable routes all influence the result.
- Allow roughly 56–66 m² as an early planning guide
- A combination of roof faces may be required
- We identify connection or switchboard work early
Battery options
Plan solar, storage and EV charging together
A 13kW array can support a larger energy plan, but the solar, inverter, battery and charging equipment need to work as one design.
- Map daytime and evening demand first
- Separate essential backup loads from whole-home expectations
- Leave a clear upgrade path where staging makes sense
Pricing
Larger systems need an itemised design and quote
The final cost depends heavily on roof layout, electrical supply, approvals and any battery or EV integration. We price the designed scope rather than a generic package.
- Number and location of roof arrays
- Inverter and phase configuration
- Connection, metering and switchboard work
- Battery and EV integration
Incentives
Incentives depend on the final compliant design
Eligible residential solar and battery equipment may receive support under current federal programs. We calculate it using the final equipment and applicable rules.
- Support is not guaranteed until eligibility is confirmed
- Program requirements may change
