Yes, absolutely. A 6.6kW system generates approx 24kWh per day. The average Australian home uses 16-20kWh. This size typically covers 100% of daytime usage with surplus to export.
Yes. All Tally Energy systems are designed "Battery Ready". You can add a Tesla Powerwall or similar battery at any time in the future without replacing your panels.
You need approximately 35-40 square metres of free roof space. We can split the panels across different roof faces (e.g., North and West) to maximize sun exposure.
