Solar Design Mandurah
Energy Usage
Understanding your household's energy usage is essential for sizing a solar system in Mandurah. The average household uses around 25 kWh per day, whilst energy efficient properties may use only half that.
Consider reducing your energy consumption first through better insulation and efficient appliances, as this can reduce the solar system size needed and improve your investment returns.
Typical energy usage per person per day in Mandurah:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Matching your daily energy needs requires approximately 6.6kW of solar capacity. For best results, size your system between 9.9kW and 13.2kW to account for fluctuations in solar output throughout the day and year.
A 6.6 kW solar array in Mandurah delivers approximately 28.5 kWh daily, with generation varying seasonally from 3.51 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 Mandurah
Solar Battery Sizing
With solar-only (no battery), a 6.6 kW system provides approximately 50% self-usage in Mandurah, depending on your consumption patterns, drawing 50% from the grid. Installing a 10 kWh battery boosts your energy independence to around 86% per year, cutting grid dependency down to 14%.
