Solar Design DULWICH HILL 2203

Energy Usage

The right solar system size for your DULWICH HILL 2203 property depends on how much electricity you use each day. Energy consumption patterns vary widely in DULWICH HILL 2203, but 25 kWh per day is a useful starting point for comparing solar system sizes and expected savings.

Every kWh you save through efficiency improvements is worth real money — and also means you need fewer solar panels to cover your remaining usage.

Typical energy usage per person per day in DULWICH HILL 2203:

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

A 6.6kW system covers average consumption, but sizing slightly larger can help offset seasonal dips and future increases in usage from EVs or heat pumps. Systems sized between 9.9kW and 13.2kW perform best, accounting for natural fluctuations in solar production.

While June is the weakest month for solar in DULWICH HILL 2203, October more than makes up for it — and a battery can help bridge the gap between seasonal highs and lows.

1 kW 20 kW

lightbulb

A 8 kW system in DULWICH HILL 2203 can generate approximately 12537.0 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.

Calculate Electrification Savings

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 DULWICH HILL 2203

Solar Battery Sizing

Reducing that 50% grid dependency with a battery can deliver meaningful savings, especially if your area has time-of-use tariffs where evening rates are higher. The jump from 50% to 86% self-sufficiency with a 10 kWh battery is most noticeable on your evening electricity bills, when rates are often highest.

The full Photonik tool provides detailed battery savings and return on investment calculations.

0 kWh 30 kWh

lightbulb A 0kWh battery will make you about 0% self sufficient.

The sweet spot for most households is 5 – 13 kWh — larger batteries add independence but with diminishing payback, especially where feed-in tariffs are low.
