Energy Usage
Understanding your household's energy usage is essential for sizing a solar system in Sydney - Eastern Suburbs. Most households in Sydney - Eastern Suburbs use around 25 kWh per day, whilst energy efficient homes can reduce this to roughly half.
Reducing your energy consumption before installing solar can lower your system size requirements and improve returns. Consider upgrading insulation and switching to energy efficient appliances first.
Typical energy usage per person per day in Sydney - Eastern Suburbs:
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. Optimal sizing ranges from 9.9kW to 13.2kW to accommodate daily and seasonal generation variations.
A 6.6 kW solar installation in Sydney - Eastern Suburbs typically produces 28.3 kWh per day on average, with seasonal output ranging between 3.40 kWh/kW/day (June) and 4.82 kWh/kW/day (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).
