The area's 7,926 households include N/A% couple families with children, and an average household size of 2.5 — a demographic that typically has higher energy needs due to larger home sizes and greater daily electricity use.
Strong homeownership rates in Hewett further support this transition, with 71% properties owner-occupied, including 3201 homes with a mortgage and 2390 owned outright, representing households that are financially well-positioned to invest in long-term energy solutions like solar batteries.
The growing remote work trend adds another layer of opportunity, with N/A residents now working from home. This shift increases daytime electricity use, which aligns well with solar generation patterns and further strengthens the case for battery storage to capture and reuse solar energy later in the day.
Looking ahead, the presence of emerging electric vehicles owned in Hewett signals the next phase of the home energy transition. As EV adoption continues to grow, more households are recognising the benefits of integrating EV charging with solar battery systems, creating efficient, self-powered homes that maximise renewable energy use while minimising reliance on the grid.
