Energy Usage

Understanding your household's energy usage is essential for sizing a solar system in Sydney - City and Inner South. Whilst typical Sydney - City and Inner South households consume 25 kWh daily, homes with good insulation and modern appliances often use far less energy.

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 - City and Inner South:

Low (Efficient)
~5 kWh
Medium (average)
~10 kWh
High (intensive)
~15+ kWh

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. We recommend sizing between 9.9kW and 13.2kW for optimal results as solar output fluctuates daily and seasonally.

A 6.6 kW system in Sydney - City and Inner South generates approximately 28.3 kWh daily on average, with seasonal variation from 3.41 kWh/kW/day in June to 4.82 kWh/kW/day in October.

1 kW 20 kW

lightbulb We recommend 6.5 - 8.7kW, generating 50 - 100% more than you use.

A 6.6 kW system in Sydney - City and Inner South can generate approximately 0 kWh annually based on local sun conditions.

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 - City and Inner South


Solar Battery Sizing

With solar-only (no battery), a 6.6 kW system provides approximately 50% self-usage in Sydney - City and Inner South, depending on your consumption patterns, drawing 50% from the grid. Including a 10 kWh battery typically raises annual self-sufficiency to around 86%, with grid reliance dropping to 14%.
