Energy Usage
How much energy your Melbourne - Inner South 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.
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 Melbourne - Inner South:
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 array in Melbourne - Inner South delivers approximately 27.8 kWh daily, with generation varying seasonally from 3.23 kWh/kW/day in June up 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 - Inner South
Solar Battery Sizing
A 6.6 kW solar system without battery storage achieves around 50% self-sufficiency in Melbourne - Inner South, with 50% still coming from the grid. A 10 kWh battery storage system can raise your energy independence to approximately 86% annually, lowering grid reliance to 14%.
