Household Type
Based on 6.6 kW solar × 5 sun hours × Perth derate, with a 13.5 kWh battery offsetting peak-rate Synergy A1 usage and exporting the surplus at DEBS peak/off-peak rates. Real savings depend on your specific tariff plan, usage pattern, and installation — an installer confirms the final quote.
Grid: no planned outages for Kalgoorlie (6430).
The ABS counts dwellings by suburb rather than by postcode, so that total is apportioned across postcode boundaries and is approximate. Every certificate created for a new, upgraded or replaced system since 2001 counts towards the ratio above, so it is not the share of homes with solar. Where building has continued since the Census, the figure can pass 100.

Outer suburbs on the SWIS fringe experience higher outage frequency and longer restoration times due to distance from depots. Backup battery capability is strongly recommended.
Common outage causes: storm damage, equipment age, tree contact, lightning. Network infrastructure: Predominantly overhead network. Longer feeder runs mean longer restoration times.
Backup battery sizing for Kalgoorlie: with an average outage duration of 73 minutes (1.2 hours), a 5 kWh backup-capable battery is typically sufficient to maintain essential loads (lights, fridge, internet, medical equipment). For whole-home backup during longer outages, consider 10–13.5 kWh with backup capability.
