Solar & Battery Installation Adelaide Local Installers & Quotes
Design solar and battery systems for Adelaide using Photonik's professional design platform. Adelaide enjoys a Mediterranean climate with abundant sunshine and is the capital of South Australia — the state with Australia's highest per-household solar uptake. With strong generation potential and competitive installation costs, Adelaide is an excellent city for rooftop solar.
Solar Design Adelaide
Energy Usage
Properties in Adelaide average around 24 kWh daily electricity consumption — and with electricity costs continuing to rise, solar can make a real difference to household budgets. Energy consumption patterns vary widely in Adelaide, but 24 kWh per day is a useful starting point for comparing solar system sizes and expected savings.
Future-proofing is worth considering: if you plan to add an EV, heat pump, or pool, your energy needs may grow — and sizing your solar system a little larger now can save money later.
Typical energy usage per person per day in Adelaide:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Most solar installers in Adelaide would recommend starting at around 6.4kW for a household using 24 kWh per day, with room to go larger if budget allows. For best results, size your system between 9.7kW and 12.9kW to account for fluctuations in solar output throughout the day and year.
With 41.5 kWh average daily production from a 9.7 kW system, most Adelaide 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 Adelaide
Solar Battery Sizing
The 50% self-use figure reflects how much solar generation aligns with when you actually use power — shifting more usage to daylight hours can improve this without adding panels. With a 10 kWh battery, your 9.7 kW system can power your home well into the evening, bringing grid reliance down to approximately 13%.
Whether a battery is worth the investment depends on your tariff, usage patterns, and how much you value energy independence — the Photonik tool can help you compare scenarios.

Solar & Battery System Cost Adelaide
Understanding Solar & Battery System Costs
Expect to invest approximately $10,958 for a 9.7 kW solar system in Adelaide, or around $17,100 with a 10 kWh battery included. With a 5.8-year payback and a 25-year panel lifespan, a solar system in Adelaide can deliver many years of essentially free electricity after paying for itself.
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.
