Understanding your energy needs: The foundation of choosing a system size
The most crucial aspect of determining your solar system size hinges on your daily energy consumption. Here’s how to get a clear picture:
- Review your electricity bills: Look for the “daily average usage” section or divide your monthly bill by the number of days to find your average daily kWh (kilowatt-hours) usage.
- Lifestyle analysis: Do you spend most of your time at home with the air conditioner running? This will affect your consumption.
- Consider future needs: Consider potential changes in your lifestyle. Will you be running appliances more frequently after retirement? Are you planning on purchasing an electric vehicle (EV)? Factor in this additional usage when calculating your needs.
Here’s a general guideline for retired couples in Australia:
Low usage (under 15 kWh/day)
Ideal for couples with efficient appliances and minimal daytime usage. A system size of 4-5 kW might suffice.
Medium usage (15-20 kWh/day)
This is a common range for most households. A 6-8 kW system could be suitable.
High usage (above 20 kWh/day)
This could be due to pool pumps, electric hot water systems, or frequent EV charging. You might require a system exceeding 8 kW.
Remember: These are estimations. It is highly recommended that you consult a reputable solar installer who can analyse your specific needs.

Considering battery storage
Solar panels only generate power during daylight hours. A battery storage system is a good option to utilise solar energy at night or during power outages. However, batteries add significant cost to the system. Here’s what to consider:
- Usage habits: Do you use a lot of power in the evenings? Battery storage becomes more valuable if you consume a significant portion of your electricity after sunset.
- Cost vs. benefit: Weigh the upfront cost of batteries against the potential savings on your electricity bills.
- Government solar battery incentives: Check for available government rebates or incentives for battery storage systems in your state.
Battery capacity is measured in kilowatt-hours (kWh). A retired couple with moderate evening usage might benefit from a 5-10kWh battery.
Battery or not to battery?
Solar batteries store excess energy generated during the day for use at night or during peak grid pricing times. They offer greater energy independence but come with an additional cost.
Batteries might be optional for retired couples with predictable daytime usage. However, if you want complete energy independence, your nighttime power usage is high, or you experience frequent grid outages, batteries become more attractive, especially if you plan to purchase an EV.

Powering up your EV with solar: If you plan to purchase an EV, integrating an EV charger into your solar system is a great way to “fuel” your car with clean, renewable energy.
Electric vehicle (EV) charging
Consider integrating an EV charger into your solar system if you purchase an electric vehicle. Here’s what to keep in mind:
- EV charger type: Choose a Level 2 charger for faster charging at home.
- Charging habits: Estimate how often you’ll need to charge your EV and how much energy each charge will require.
- Solar integration: Ideally, charge your EV during peak sunshine hours to maximise solar energy self-consumption.
Many solar installers offer EV charger packages alongside solar system installation.
Additional factors to consider
- Roof size and orientation: Your roof’s size and orientation towards the sun significantly impact the amount of solar energy your system can generate. South-facing roofs in Australia are ideal.
- Shading: Trees or other structures casting shadows on your roof can reduce solar panel efficiency.
- Budget: Solar systems are an investment, and costs vary depending on system size, battery storage inclusions, and brand quality.
- Government solar rebates and incentives: Several incentives exist to encourage solar power adoption in Australia—research available programs in your state to offset installation costs.

Consulting a reputable Clean Energy Council-accredited solar installer is crucial. They will assess your needs, recommend an optimal system size, and guide you through the quoting and installation process.
