Solar Design Sydney - Inner West
Energy Usage
Understanding your household's energy usage is essential for sizing a solar system in Sydney - Inner West. Energy consumption patterns vary widely in Sydney - Inner West, but 25 kWh per day is a useful starting point for comparing solar system sizes and expected savings.
Simple changes like sealing draughts, upgrading to LED lighting, and setting hot water timers often cost far less than extra solar panels and deliver immediate bill savings.
Typical energy usage per person per day in Sydney - Inner West:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
You'll need around 6.6kW of solar to match your average consumption. For best results, size your system between 9.9kW and 13.2kW to account for fluctuations in solar output throughout the day and year.
The seasonal spread from 3.40 kWh/kW/day in June to 4.82 kWh/kW/day in October is normal for Sydney - Inner West — good system sizing accounts for this variation.
Solar & Energy Savings
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of 181.0 per month (2166.0 annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of 60.0 per month (720.0 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 121.0 (1446.0 annually).

Battery Storage Sydney - Inner West
Solar Battery Sizing
A solar-only system in Sydney - Inner West covers about 50% of your energy needs during daylight hours, but without a battery the 50% you use at night still comes from the grid. A 10 kWh battery makes the most difference in winter when daylight hours are shorter — helping maintain closer to 86% self-sufficiency year-round rather than just in summer.
