You know exactly what’s coming: consecutive 35–40°C days, air-con running constantly, and a January bill large enough to cancel plans. Too many WA households reach financial breaking point each summer just trying to stay cool. Sarah in Applecross installed an oversized inverter and extra panels last autumn. Even on 41°C days her three split systems plus pool pump run 93% self-powered. Her projected summer bill is under $80 for the quarter. Data from correctly sized Sure Renewables systems shows 90–95% self-consumption through peak summer, turning extreme heat into negligible cost. Staying comfortable no longer needs to come at the expense of your budget. How many more extreme summers will you survive before your cooling costs finally stop hurting?
