Energy Usage
The right solar system size for your Sydney - Inner West property depends on how much electricity you use each day. Whilst typical Sydney - Inner 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 West:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Matching your daily energy needs requires approximately 6.6kW of solar capacity. For best results, size your system between 9.9kW and 13.2kW to account for fluctuations in solar output throughout the day and year.
In Sydney - Inner West, a 6.6 kW installation produces around 28.3 kWh per day on average, though output ranges from 3.40 kWh/kW/day during June to 4.82 kWh/kW/day in 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 West
Solar Battery Sizing
A 6.6 kW solar system without battery storage achieves around 50% self-sufficiency in Sydney - Inner West, with 50% still coming from the grid. Adding a 10 kWh battery increases energy independence to approximately 86% annually, reducing grid reliance to 14%.
