Solar Design Sydney - Northern Beaches
Energy Usage
The right solar system size for your Sydney - Northern Beaches property depends on how much electricity you use each day. Most households in Sydney - Northern Beaches use around 25 kWh per day, whilst energy efficient homes can reduce this to roughly half.
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 - Northern Beaches:
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.
Expect around 28.4 kWh daily from a 6.6 kW system in Sydney - Northern Beaches, with production varying from 3.42 kWh/kW/day in 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 - Northern Beaches
Solar Battery Sizing
A 6.6 kW solar system without battery storage achieves around 50% self-sufficiency in Sydney - Northern Beaches, with 50% still coming from the grid. With a 10 kWh battery added, energy independence increases to approximately 86% per year, whilst grid dependency falls to 14%.
Accurate battery savings and ROI require the full Photonik design platform for comprehensive calculations.
