Energy Usage

To choose the right solar system in Sydney - Parramatta, start by understanding your daily electricity consumption. The average household uses around 25 kWh per day, whilst energy efficient properties may use only half that.

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 - Parramatta:

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. Sizing your system between 9.9kW and 13.2kW accounts for daily and seasonal variations in solar generation.

In Sydney - Parramatta, a 6.6 kW installation produces around 28.4 kWh per day on average, though output ranges from 3.41 kWh/kW/day during June to 4.82 kWh/kW/day in October.

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

A 6.6 kW system in Sydney - Parramatta 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 - Parramatta


Solar Battery Sizing

A 6.6 kW solar-only setup in Sydney - Parramatta delivers around 50% self-sufficiency, leaving 50% dependent on grid electricity. With a 10 kWh battery added, energy independence increases to approximately 86% per year, whilst grid dependency falls to 14%.
