Solar Design CHATSWOOD 2067
Energy Usage
Your daily energy consumption determines the optimal solar system size for your home in CHATSWOOD 2067. The average household uses between 20-30 kWh per day, whilst energy efficient properties may use only half that.
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 CHATSWOOD 2067:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
You'll need around 4.4kW of solar to match your average consumption. We recommend sizing 50-100% above your usage for optimal results as solar output fluctuates daily and seasonally.
An 8 kW system in CHATSWOOD 2067 generates approximately 34 kWh daily on average. Output varies seasonally (41% difference), with peak generation of 39 kWh in October and 27 kWh in June. This variation is typical for your latitude and should be accounted for when sizing your system.

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 CHATSWOOD 2067
Solar Battery Sizing
With solar-only (no battery), an 8 kW system provides approximately 50% self-usage in CHATSWOOD 2067, depending on your consumption patterns, drawing 50% from the grid. Adding a 5 kWh battery increases energy independence to approximately 68% annually, reducing grid reliance to 32%.
Note: For accurate battery savings and ROI calculations, use the full Photonik design tool.

Solar & Battery System Cost CHATSWOOD 2067
Understanding Solar & Battery System Costs
A 8 kW solar system in CHATSWOOD 2067 costs approximately $8970, while adding a 5 kWh battery increases the total to around $12028. Solar-only systems typically pay for themselves in around 3.9 years, whilst adding battery storage usually extends payback whilst increasing energy independence.
The cost breakdown shows estimates for equipment costs, installation labour, and GST. Adjust system size and battery storage to see how it affects total investment and payback periods.
