Energy Usage
The right solar system size for your Townsville property depends on how much electricity you use each day. Average daily consumption sits at around 27 kWh for most Townsville homes, with energy efficient properties typically using substantially less.
Before installing solar it is often a good investment to first look to reduce your energy consumption where possible. This can be done through improved insulation, and energy efficient appliances.
Typical energy usage per person per day in Townsville:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
For a Townsville household using 27 kWh daily, 7.2kW is the baseline — your roof space, budget, and future plans will determine whether to go larger. A system in the 10.9kW to 14.5kW range also gives you headroom if your energy needs grow — from a new EV, heat pump, or home office.
While June is the weakest month for solar in Townsville, October more than makes up for it — and a battery can help bridge the gap between seasonal highs and lows.
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 Townsville
Solar Battery Sizing
Without battery storage, a 10.9 kW system in Townsville achieves approximately 50% energy self-sufficiency, with the remaining 50% supplied by the grid. The jump from 50% to 83% self-sufficiency with a 10 kWh battery is most noticeable on your evening electricity bills, when rates are often highest.
Local incentives and rebates can significantly improve battery economics — check what's available in Townsville and use the Photonik design tool to factor them into your calculations.

Solar & Battery System Cost Townsville
Understanding Solar & Battery System Costs
For Townsville homeowners looking to reduce their electricity bills, a $11,953 solar installation can dramatically lower or even eliminate that ongoing monthly cost. After the 5.5-year payback period, your solar system continues producing — at current rates, that's potentially 15+ years of savings with minimal maintenance costs.
Cost estimates cover equipment, installation labour, and applicable taxes. Modify the system size and battery storage sliders to explore different investment levels and payback periods.
