Solar & Battery Installation Melbourne Local Installers & Quotes
Design solar and battery systems for Melbourne using Photonik's professional design platform. While Melbourne's weather is famously variable, the city still receives strong solar generation across the year. With Victoria's Solar Homes Program providing rebates and high electricity prices, Melbourne homeowners continue to adopt solar at impressive rates.

Energy Usage
With electricity costs rising across Melbourne, typical households using around 24 kWh daily stand to benefit significantly from switching to solar power. The average household uses around 24 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 Melbourne:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
In Melbourne, a 6.3kW system would cover your average daily consumption and start reducing your electricity bills from day one. Sizing your system between 9.5kW and 12.6kW accounts for daily and seasonal variations in solar generation.
With 40.0 kWh average daily production from a 9.5 kW system, most Melbourne households can offset the majority of their electricity consumption.
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 Melbourne
Solar Battery Sizing
At around 50% self-sufficiency without a battery, you're still buying 50% of your electricity from the grid — mostly in the evenings and overnight when solar isn't generating. With a 10 kWh battery added, energy independence increases to approximately 88% per year, whilst grid dependency falls to 12%.
Battery economics depend on your specific tariff structure and usage patterns — the Photonik design tool can model these scenarios with your actual electricity plan.

Solar & Battery System Cost Melbourne
Understanding Solar & Battery System Costs
Solar prices in Melbourne have come down significantly in recent years — a 9.5 kW system now costs around $11,160, making the economics more attractive than ever. Solar-only systems typically pay for themselves in around 6.1 years, whilst adding battery storage usually extends payback whilst increasing energy independence.
These are estimated costs — actual prices vary based on your roof type, equipment choice, and installer. We recommend getting at least three quotes to compare for your Melbourne property.
STC Rebates Melbourne
STC rebates in Melbourne are calculated based on your system size, location zone factor, and deeming period until 2031.
