Why a battery makes sense in Cockburn

Rapid growth area with new subdivisions
Modern homes with energy-efficient design
Most developments have roofs oriented well for solar
Coastal proximity means salt air matters in western parts
Existing solar uplift: A typical 6.6-10 kW system here makes 35-39 kWh/day (6.6kW) on a summer day — storing the excess is worth ~33c/kWh here versus 2–10c/kWh for export
Backup during outages: With 18-24 kWh typical daily usage here, critical-circuit backup keeps refrigeration, lighting, and security running through grid events
