Energy Usage
The right solar system size for your Brisbane Inner City property depends on how much electricity you use each day. Whilst typical Brisbane Inner City households consume 25 kWh daily, homes with good insulation and modern appliances often use far less energy.
Lowering energy usage before solar installation—via improved insulation and efficient appliances—often reduces required system size and enhances financial returns.
Typical energy usage per person per day in Brisbane Inner City:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A 6.6kW solar system would typically cover your average daily electricity consumption. We recommend sizing between 9.9kW and 13.2kW for optimal results as solar output fluctuates daily and seasonally.
Expect around 29.1 kWh daily from a 6.6 kW system in Brisbane Inner City, with production varying from 3.72 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 Inner City
Solar Battery Sizing
Without battery storage, a 6.6 kW system in Brisbane Inner City 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%.
Accurate battery savings and ROI require the full Photonik design platform for comprehensive calculations.
