Thornlie sits in STC Zone 3, which means a typical 6.6kW solar system attracts the standard small-scale technology certificate rebate (around $1,500–$1,800 for a 2026 install — the amount steps down each year as the scheme closes in 2030). With 5 peak sun hours per day on average, a well-orientated 6.6kW array generates roughly 12045 kWh per year.
Eligible Thornlie households can also access the WA Battery Rebate (Synergy Supported Solutions List installers only — every installer in our directory marked “WA Rebate Eligible” is approved). The rebate is $130/kWh up to a $1,300 cap on a 10kWh battery.
