Solar Design Perth - Inner
Energy Usage
How much energy your Perth - Inner home uses daily directly impacts the solar system size you'll need. Average daily consumption sits at around 25 kWh for most Perth - Inner homes, with energy efficient properties typically using substantially less.
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 Perth - Inner:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
You'll need around 6.6kW of solar to match your average consumption. We recommend sizing between 9.9kW and 13.2kW for optimal results as solar output fluctuates daily and seasonally.
A 6.6 kW solar array in Perth - Inner delivers approximately 28.6 kWh daily, with generation varying seasonally from 3.53 kWh/kW/day in June up to 4.83 kWh/kW/day in February.
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 Perth - Inner
Solar Battery Sizing
A 6.6 kW solar system without battery storage achieves around 50% self-sufficiency in Perth - Inner, with 50% still coming from the grid. Adding a 10 kWh battery increases energy independence to approximately 86% annually, reducing grid reliance to 14%.
