Perth · Peppermint Grove
Solar and battery guidance for Peppermint Grove's prestige riverside homes. Discreet installation matters on Australia's smallest LGA, and high consumption rewards a properly sized battery.
Quick answer
A typical Peppermint Grove home uses 25-35 kWh a day and suits 8-13 kW of solar with a 13.5-20 kWh battery. At current Synergy rates that setup saves about $2,900 a year, and the WA Battery Scheme covers up to $1,300 of the battery.
