Solar Design Sydney - Blacktown

Energy Usage

How much energy your Sydney - Blacktown home uses daily directly impacts the solar system size you'll need. The average household uses around 25 kWh per day, whilst energy efficient properties may use only half that.

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 - Blacktown:

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

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.

A 6.6 kW solar installation in Sydney - Blacktown typically produces 28.4 kWh per day on average, with seasonal output ranging between 3.41 kWh/kW/day (June) and 4.82 kWh/kW/day (October).

Solar System Size: 6.6 (0 kWh/day)

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 - Blacktown 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).

EV Charging & V2G Sydney - Blacktown

Electric Vehicle Charging with Solar

Charging your electric vehicle with solar power is one of the most cost-effective ways to fuel your car. In Sydney - Blacktown, solar-powered EV charging can reduce your transportation costs significantly compared to grid electricity or petrol.

Vehicle-to-Grid (V2G) technology allows your EV battery to act as additional storage for your home, providing backup power and helping balance grid demand. This emerging technology can further maximize the value of your solar and battery investment.

When planning your solar system, consider your EV charging needs. A typical EV uses 15-20 kWh per 100km, so daily charging can add 5-15 kWh to your energy requirements. Our full design tool can help you plan a system that accommodates both your home and EV charging needs.

Solar & Battery System Cost Sydney - Blacktown

Understanding Solar & Battery System Costs

A 6.6 kW solar system in Sydney - Blacktown is priced at approximately $7,661, whilst adding 10 kWh of battery storage increases the total investment to around $12,904. Solar-only systems typically pay for themselves in around 5.1 years, whilst adding battery storage usually extends payback whilst increasing energy independence.

The cost breakdown shows estimates for equipment costs, installation labour, and applicable taxes. Adjust system size and battery storage to see how it affects total investment and payback periods.
