How do I calculate what size solar system I need?

Determining the perfect solar system size for your Queensland home is crucial for maximising energy generation and savings. While a general rule suggests a 6.6 kW system as a good starting point, several factors influence the ideal size for your specific needs. Here’s more information on determining the size suitable for your home and family. 

Here's how to calculate your ideal system size:

  1. Analyse your electricity bills: Gather your average daily energy consumption from the past few months.

  2. Consider your location: Queensland boasts excellent sunshine (and heat), with Brisbane averaging almost 10 hours of solar-producing sunlight hours per day.

  3. Factor in your budget and available roof space: Larger systems generate more power but come at a higher cost and require more space.

Is 6.6 kW solar enough for a house?

A 6.6 kW solar system is a popular choice in Queensland and can be sufficient for many households with moderate energy consumption. However, several factors can influence whether 6.6 kW is enough for your specific needs:

  1. Energy consumption: High energy consumers might require a larger system like 10kW or more.

  2. Future needs: Consider anticipated changes in your energy usage, like adding appliances or electric vehicles.

  3. Feed-in tariffs: These vary across regions, affecting the financial feasibility of larger systems.
