Energy Usage
Understanding your household's energy usage is essential for sizing a solar system in Brisbane - East. Whilst typical Brisbane - East households consume 25 kWh daily, homes with good insulation and modern appliances often use far less energy.
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 Brisbane - East:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A solar system sized at approximately 6.6kW would cover your typical daily energy needs. Optimal sizing ranges from 9.9kW to 13.2kW to accommodate daily and seasonal generation variations.
A 6.6 kW system in Brisbane - East generates approximately 29.2 kWh daily on average, with seasonal variation from 3.73 kWh/kW/day in June to 4.87 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 Brisbane - East
Solar Battery Sizing
Without battery storage, a 6.6 kW system in Brisbane - East achieves approximately 50% energy self-sufficiency, with the remaining 50% supplied by the grid. Installing a 10 kWh battery boosts your energy independence to around 86% per year, cutting grid dependency down to 14%.
