Energy Usage
The right solar system size for your Brisbane - West property depends on how much electricity you use each day. Whilst typical Brisbane - West households consume 25 kWh daily, homes with good insulation and modern appliances often use far less energy.
It's worth reducing your energy usage before going solar, as this can decrease the system size you need and improve payback. Focus on better insulation and energy efficient appliances.
Typical energy usage per person per day in Brisbane - 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. Sizing your system between 9.9kW and 13.2kW accounts for daily and seasonal variations in solar generation.
A 6.6 kW solar installation in Brisbane - West typically produces 29.1 kWh per day on average, with seasonal output ranging between 3.72 kWh/kW/day (June) and 4.87 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 Brisbane - West
Solar Battery Sizing
Without battery storage, a 6.6 kW system in Brisbane - West achieves approximately 50% energy self-sufficiency, with the remaining 50% supplied by the grid. Adding a 10 kWh battery increases energy independence to approximately 86% annually, reducing grid reliance to 14%.
