Energy Usage
To choose the right solar system in Sydney - Inner South West, start by understanding your daily electricity consumption. Whilst typical Sydney - Inner South West households consume 25 kWh daily, homes with good insulation and modern appliances often use far less energy.
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 Sydney - Inner South West:
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. Systems sized between 9.9kW and 13.2kW perform best, accounting for natural fluctuations in solar production.
A 6.6 kW solar installation in Sydney - Inner South West typically produces 28.3 kWh per day on average, with seasonal output ranging between 3.40 kWh/kW/day (June) and 4.82 kWh/kW/day (October).
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 Sydney - Inner South West
Solar Battery Sizing
With solar-only (no battery), a 6.6 kW system provides approximately 50% self-usage in Sydney - Inner South West, depending on your consumption patterns, drawing 50% from the grid.
