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.
