Across 5222, rooftop solar systems collectively generate approximately 2,491,000 kWh of clean energy each year, based on an average system size of 5.2 kW. At current electricity rates, that's equivalent to around $747,300 of clean energy at grid electricity costs annually.
Solar Battery energy storage is growing just as rapidly, with 27 battery systems now installed across 5222. Together, these systems provide 310 kWh of stored energy capacity, with the average household storing around 11.5 kWh. This means local solar households can typically power their homes for 4.6 hours each night using clean energy they generated themselves during the day.
So instead of sending excess solar energy back to the grid for lower returns, Willoughby homeowners are now storing and using their own clean power around the clock. This smart approach not only reduces reliance on expensive coal-generated electricity from the grid, it protects against blackouts, improves sustainability, and maximises their solar investment and long-term financial returns.

Willoughby Demographics & Energy Profile
The 2021 Australian Bureau of Statistics data highlights why Willoughby is emerging as a hotspot for solar battery adoption. The area's 658 households include N/A% couple families with children, and an average household size of 2 — a demographic that typically has higher energy needs due to larger home sizes and greater daily electricity use.
Strong homeownership rates in Willoughby further support this transition, with 35% properties owner-occupied, including 84 homes with a mortgage and 145 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 Willoughby 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.
