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 Melbourne - South East:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
You'll need around 6.6kW of solar to match your average consumption. Optimal sizing ranges from 9.9kW to 13.2kW to accommodate daily and seasonal generation variations.
Expect around 27.8 kWh daily from a 6.6 kW system in Melbourne - South East, with production varying from 3.23 kWh/kW/day in June to 4.80 kWh/kW/day in February.
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 Melbourne - South East
Solar Battery Sizing
With solar-only (no battery), a 6.6 kW system provides approximately 50% self-usage in Melbourne - South East, depending on your consumption patterns, drawing 50% from the grid. Including a 10 kWh battery typically raises annual self-sufficiency to around 86%, with grid reliance dropping to 14%.
