Solar Design Townsville


Energy Usage

Your daily energy consumption determines the optimal solar system size for your home in Townsville. The average household uses around 25 kWh per day, whilst energy efficient properties may use only half that.

Consider reducing your energy consumption first through better insulation and efficient appliances, as this can reduce the solar system size needed and improve your investment returns.

Typical energy usage per person per day in Townsville:

Low (Efficient)
~5 kWh
Medium (average)
~10 kWh
High (intensive)
~15+ kWh

Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.

Solar System Sizing

To offset your average consumption, you'd need roughly 6.6kW of solar capacity. Sizing your system between 9.9kW and 13.2kW accounts for daily and seasonal variations in solar generation.

A 6.6 kW solar installation in Townsville typically produces 29.8 kWh per day on average, with seasonal output ranging between 4.00 kWh/kW/day (June) and 4.89 kWh/kW/day (October).

lightbulb We recommend 6.5 - 8.7kW, generating 50 - 100% more than you use.

A 6.6 kW system in Townsville can generate approximately 0 kWh annually based on local sun conditions.

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

Solar-only systems in Townsville typically provide 50% self-usage with a 6.6 kW installation, meaning 50% of your electricity still comes from the grid. Installing a 10 kWh battery boosts your energy independence to around 86% per year, cutting grid dependency down to 14%.

To get precise battery savings and payback figures, use the complete Photonik design platform.

Solar & Battery System Cost Townsville


Understanding Solar & Battery System Costs

A 6.6 kW solar system in Townsville is priced at approximately $7,661, whilst adding 10 kWh of battery storage increases the total investment to around $12,904. Solar-only systems typically pay for themselves in around 5.0 years, whilst adding battery storage usually extends payback whilst increasing energy independence.

Pricing includes equipment, labour, and taxes. Use the sliders to adjust system size and battery capacity, observing how changes impact total cost and payback.
