Solar Design Sydney - North Sydney and Hornsby
Energy Usage
How much energy your Sydney - North Sydney and Hornsby home uses daily directly impacts the solar system size you'll need. Whilst typical Sydney - North Sydney and Hornsby households consume 25 kWh daily, homes with good insulation and modern appliances often use far less energy.
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 Sydney - North Sydney and Hornsby:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A 6.6kW solar system would typically cover your average daily electricity consumption. Sizing your system between 9.9kW and 13.2kW accounts for daily and seasonal variations in solar generation.
A 6.6 kW solar array in Sydney - North Sydney and Hornsby delivers approximately 28.4 kWh daily, with generation varying seasonally from 3.41 kWh/kW/day in June up 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 - North Sydney and Hornsby
Solar Battery Sizing
A 6.6 kW solar system without battery storage achieves around 50% self-sufficiency in Sydney - North Sydney and Hornsby, with 50% still coming from the grid. Installing a 10 kWh battery boosts your energy independence to around 86% per year, cutting grid dependency down to 14%.
Accurate battery savings and ROI require the full Photonik design platform for comprehensive calculations.
