Old Erowal Bay Demographics & Energy Profile
The 2021 Australian Bureau of Statistics data highlights why Old Erowal Bay is emerging as a hotspot for solar battery adoption. The area's 26,054 households include N/A% couple families with children, and an average household size of 2.3 — a demographic that typically has higher energy needs due to larger home sizes and greater daily electricity use.
Strong homeownership rates in Old Erowal Bay further support this transition, with 53% properties owner-occupied, including 5226 homes with a mortgage and 8495 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 Old Erowal Bay 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.

Old Erowal Bay is seeing growing enthusiasm for energy independence, and battery adoption is following the broader Shoalhaven region’s upward trend. While there’s still early uptake—just one registered battery system so far in 2540, offering 14.4 kWh of storage—the future looks bright as more residents see the value in storing excess daytime solar for night-time use. Popular battery system sizes for homes include 6.5 kWh through to 13.5 kWh, with leading brands like Tesla (13.5 kWh), BYD (13.8 kWh), and Sungrow (9.6 kWh) regularly installed. These systems can deliver bill reductions that add up fast:
• 6.5 kWh: $900–$1,200 annual savings • 10 kWh: $1,200–$1,600 annual savings • 13.5 kWh: $1,500–$2,000 annual savings
With over 61,917 kW of solar already generating power in local homes, battery storage helps you keep more of that energy on site, further reducing grid reliance. Battery systems for solar panels are not just about savings—they also add resilience during blackouts and can increase your home’s value.
Recent installations in Old Erowal Bay reflect a community that’s switched on to renewable energy, with over 10,270 solar systems and a combined capacity of 61,917 kW. The next wave is all about solar batteries storage, allowing households to capture excess solar and use it when it counts most.
Interest in solar batteries and Virtual Power Plants (VPPs) is also on the rise in Old Erowal Bay. The Australian Government’s solar batteries rebate for NSW homeowners can significantly reduce upfront costs, with discounts up to 30% of battery cost or approximately $3,400–$4,000 off a typical 11.5–13.5 kWh system. This can halve payback periods, bringing them down to just 3–4 years. By joining a VPP, residents can further boost their returns, earning credits by sharing stored energy with the grid during peak times and increasing the resilience of their home energy systems.
