Lake Illawarra Demographics & Energy Profile
The 2021 Australian Bureau of Statistics data highlights why Lake Illawarra is emerging as a hotspot for solar battery adoption. The area's 10,106 households include N/A% couple families with children, and an average household size of 2.4 — a demographic that typically has higher energy needs due to larger home sizes and greater daily electricity use.
Strong homeownership rates in Lake Illawarra further support this transition, with 59% properties owner-occupied, including 2351 homes with a mortgage and 3577 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 Lake Illawarra 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.

Solar Battery Rebates, Cost & Quotes Lake Illawarra, NSW 2528
Lake Illawarra is embracing the solar revolution, with more households and businesses making the switch to solar power systems and, increasingly, solar battery storage. Thanks to abundant sunshine—an average of around 16 MJ/m² per day, translating to roughly 4.4 kWh per square metre—our region is primed for efficient solar energy generation. With over 9,400 dwellings and a high rate of home ownership (about 63% owned outright or with a mortgage), it’s no wonder locals are interested in harnessing the sun to cut electricity costs and boost resilience. Battery storage is the natural next step for those with solar panels, helping capture excess daytime energy for use in the evening or during blackouts, and annual energy savings for homeowners with solar batteries in Lake Illawarra can be significant—often upwards of $1,200 to $2,400 per year depending on usage and battery size.
Battery adoption is on the rise in 2528, with over 2,700 solar installations already on rooftops and more than 15,500 kW of solar capacity in the community. While the current number of battery systems is still growing—the data shows at least one recent battery install (8.1 kWh, 5 kW) locally—the trend is clear: more Lake Illawarra homes want to maximise their solar savings and energy independence. For households, the average battery charge time is typically just a few hours on a sunny day, and the suburb’s solar system density is creating a real buzz in the neighbourhood. Here’s what you could expect to save on annual bills, based on popular system sizes:
• 5 kWh battery: save $700–$1,200 per year • 10 kWh battery: save $1,300–$2,000 per year • 13.5 kWh battery: save $1,800–$2,400 per year

The interest in solar batteries, Virtual Power Plants (VPPs), and home energy management is only increasing in Lake Illawarra. Homeowners in NSW can now access the Australian Federal Government’s Solar Battery Rebate, making it more affordable to install solar batteries. This rebate can cover up to 30% of the battery cost—so a typical 11.5–13.5 kWh battery might net a discount of $3,400–$4,000 off installation, potentially halving payback periods to just 3–4 years. Plus, joining a VPP can unlock extra value by letting you sell stored energy back to the grid, boosting your savings and supporting local grid resilience.
