Solar & Battery Installation Sydney Local Installers & Quotes
Design solar and battery systems for Sydney using Photonik's professional design platform. Sydney's sunny climate and high electricity prices make rooftop solar a compelling investment. As Australia's largest city, Sydney has seen rapid solar adoption, with homeowners benefiting from strong generation potential and federal STCs that reduce installation costs.

Energy Usage
With electricity costs rising across Sydney, typical households using around 25 kWh daily stand to benefit significantly from switching to solar power. With electricity prices trending upward, even small reductions in your 25 kWh daily consumption can noticeably lower your bills — and solar takes this further by offsetting much of what you do use.
Your actual usage may differ from the 25 kWh/day average for Sydney — checking your electricity bills or smart meter data gives a more accurate starting point for solar sizing.
Typical energy usage per person per day in Sydney:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Most solar installers in Sydney would recommend starting at around 6.6kW for a household using 25 kWh per day, with room to go larger if budget allows. Systems sized between 9.9kW and 13.2kW perform best, accounting for natural fluctuations in solar production.
In Sydney, a 9.9 kW installation produces around 42.5 kWh per day on average, though output ranges from 3.41 kWh/kW/day during 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
Solar Battery Sizing
Even without a battery, 50% self-sufficiency from a 9.9 kW system in Sydney means a significant reduction in your electricity bills. 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.

Solar & Battery System Cost Sydney
Understanding Solar & Battery System Costs
A 9.9 kW solar system in Sydney costs approximately $11,137, while adding a 10 kWh battery increases the total to around $17,278. Payback periods for solar-only installations average approximately 5.8 years, whilst battery storage extends payback but significantly improves 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.
