Solar Design Perth - North East
Energy Usage
How much energy your Perth - North East home uses daily directly impacts the solar system size you'll need. Average daily consumption sits at around 25 kWh for most Perth - North East homes, with energy efficient properties typically using substantially less.
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 Perth - North 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. Sizing your system between 9.9kW and 13.2kW accounts for daily and seasonal variations in solar generation.
In Perth - North East, a 6.6 kW installation produces around 28.6 kWh per day on average, though output ranges from 3.53 kWh/kW/day during June 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 - North East
Solar Battery Sizing
Solar-only systems in Perth - North East typically provide 50% self-usage with a 6.6 kW installation, meaning 50% of your electricity still comes from the grid. With a 10 kWh battery added, energy independence increases to approximately 86% per year, whilst grid dependency falls to 14%.
