Solar Design Sydney - Sutherland
Energy Usage
To choose the right solar system in Sydney - Sutherland, start by understanding your daily electricity consumption. Whilst typical Sydney - Sutherland households consume 25 kWh daily, homes with good insulation and modern appliances often use far less energy.
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 Sydney - Sutherland:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
To offset your average consumption, you'd need roughly 6.6kW of solar capacity. Optimal sizing ranges from 9.9kW to 13.2kW to accommodate daily and seasonal generation variations.
In Sydney - Sutherland, a 6.6 kW installation produces around 28.3 kWh per day on average, though output ranges from 3.40 kWh/kW/day during June to 4.82 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 Sydney - Sutherland
Solar Battery Sizing
Solar-only systems in Sydney - Sutherland typically provide 50% self-usage with a 6.6 kW installation, meaning 50% of your electricity still comes from the grid. Installing a 10 kWh battery boosts your energy independence to around 86% per year, cutting grid dependency down to 14%.
To get precise battery savings and payback figures, use the complete Photonik design platform.
