Solar Design Sydney - Outer West and Blue Mountains
Energy Usage
How much energy your Sydney - Outer West and Blue Mountains home uses daily directly impacts the solar system size you'll need. Whilst typical Sydney - Outer West and Blue Mountains households consume 25 kWh daily, homes with good insulation and modern appliances often use far less energy.
Lowering energy usage before solar installation—via improved insulation and efficient appliances—often reduces required system size and enhances financial returns.
Typical energy usage per person per day in Sydney - Outer West and Blue Mountains:
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. Systems sized between 9.9kW and 13.2kW perform best, accounting for natural fluctuations in solar production.
In Sydney - Outer West and Blue Mountains, a 6.6 kW installation produces around 28.2 kWh per day on average, though output ranges from 3.37 kWh/kW/day during June to 4.81 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 Sydney - Outer West and Blue Mountains
Solar Battery Sizing
Solar-only systems in Sydney - Outer West and Blue Mountains typically provide 50% self-usage with a 6.6 kW installation, meaning 50% of your electricity still comes from the grid. Adding a 10 kWh battery increases energy independence to approximately 86% annually, reducing grid reliance to 14%.
Accurate battery savings and ROI require the full Photonik design platform for comprehensive calculations.
