LONGi panel options & system sizing

Popular system sizes we install

  • 6.6kW Solar: A great starting point for many homes, solid daytime coverage and a strong return in Central QLD.
  • 13.3kW Solar: Ideal for larger households, higher usage, or those wanting to maximise savings.
  • Battery-ready design: We can size and configure the inverter and switchboard so you can add a battery later if it makes sense.

We’ll recommend the right LONGi panel configuration based on your roof space, shading, switchboard, and usage patterns (not a one-size-fits-all template).
