Solar Design Northern Territory
Energy Usage
How much energy your Northern Territory home uses daily directly impacts the solar system size you'll need. Typical homes consume approximately 25 kWh daily on average, though well-insulated properties with efficient appliances often use significantly less.
It's worth reducing your energy usage before going solar, as this can decrease the system size you need and improve payback. Focus on better insulation and energy efficient appliances.
Typical energy usage per person per day in Northern Territory:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A solar system sized at approximately 6.6kW would cover your typical daily energy needs. We recommend sizing between 9.9kW and 13.2kW for optimal results as solar output fluctuates daily and seasonally.
A 6.6 kW solar installation in Northern Territory typically produces 30.2 kWh per day on average, with seasonal output ranging between 4.20 kWh/kW/day (June) and 4.92 kWh/kW/day (March).
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).
Battery Storage Northern Territory
Solar Battery Sizing
Without battery storage, a 6.6 kW system in Northern Territory achieves approximately 50% energy self-sufficiency, with the remaining 50% supplied by the grid. Adding a 10 kWh battery increases energy independence to approximately 86% annually, reducing grid reliance to 14%.

Solar & Battery System Cost Northern Territory
Understanding Solar & Battery System Costs
A 6.6 kW solar system in Northern Territory is priced at approximately $7,661, whilst adding 10 kWh of battery storage increases the total investment to around $12,904. Most solar-only systems reach payback in approximately 5.0 years, though battery storage lengthens payback periods whilst substantially boosting energy independence.
The breakdown covers equipment, installation, and taxes. Adjust the system size and battery sliders to see how different configurations affect your investment and payback timeline.
