The 5223 postcode, which includes Cassini, Brownlow, D’estrees Bay, Stun’sail Boom, Stun'sail Boom, Bay Of Shoals, Birchmore, Brownlow Ki, Cape Borda, Cygnet River, De Mole River, D'estrees Bay, Duncan, Emu Bay, Flinders Chase, Gosse, Haines, Harriet River, Karatta, Kingscote, Kohinoor, Macgillivray, Menzies, Middle River, Nepean Bay, Newland, North Cape, Seal Bay, Seddon, Stokes Bay, Vivonne Bay, Western River and Wisanger, has 2,041 households. Of these, 982 homes — or 48.1% — have installed rooftop solar panels, reflecting the community's growing move toward renewable energy. With more Cassini residents looking to reduce their reliance on the electricity grid, many are now turning to solar battery storage as the next step. Solar batteries help homeowners lower energy bills, increase energy independence, and improve long-term sustainability.
According to daily average sunshine data from the nearest weather station at Cape Cassini Wilderness Retreat, households in this community receive approximately 4.7 kWh of sunlight per day. Across 5223, rooftop solar systems collectively generate approximately 9,137,000 kWh of clean energy each year, based on an average system size of 6.3 kW. At current electricity rates, that's equivalent to around $2,741,100 of clean energy at grid electricity costs annually.
Solar Battery energy storage is growing just as rapidly, with 73 battery systems now installed across 5223. Together, these systems provide 941 kWh of stored energy capacity, with the average household storing around 12.9 kWh. This means local solar households can typically power their homes for 5.2 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, Cassini 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.

Cassini Demographics & Energy Profile
The 2021 Australian Bureau of Statistics data highlights why Cassini is emerging as a hotspot for solar battery adoption. The area's 2,041 households include N/A% couple families with children, and an average household size of 2.2 — a demographic that typically has higher energy needs due to larger home sizes and greater daily electricity use.
Strong homeownership rates in Cassini further support this transition, with 49% properties owner-occupied, including 413 homes with a mortgage and 584 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 Cassini 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 Cassini, SA 5223
There’s a real shift happening in Cassini as more homes and businesses turn to solar energy and, increasingly, solar battery storage. With Cassini’s excellent average daily solar exposure of around 16.9 MJ/m² (about 4.7 kWh per square metre per day), it’s no wonder locals are harnessing the sun to cut their energy costs. The area’s high home ownership—over 70% of dwellings are owned outright or with a mortgage—and the average household size of 2.2 means plenty of roofs are ready for solar panels and, now, solar batteries. For many, adding battery storage is the obvious next step, making the most of every sun-soaked day and boosting annual energy savings, often reaching well over $1,200 per year for homeowners with the right system.
Cassini (postcode 5223) is already ahead of the curve, with 982 solar installations across the region totalling more than 6,200 kW. Battery adoption is on the rise too, with 73 battery systems now installed, offering a combined 940.8 kWh of storage. That’s enough to power dozens of homes through the evening or even during a blackout. Popular solar battery brands here include Tesla (13.5 kWh), BYD (13.8 kWh), and Alpha ESS (7.8 kWh), each bringing solid performance and reliability. On average, Cassini residents are seeing: • Small system (5–7 kWh): $800–$1,000 off annual bills • Medium system (10–13.5 kWh): $1,200–$1,600 off • Large system (above 15 kWh): $1,800–$2,400 in yearly savings
Recent installations in Cassini show how rapidly the community is embracing batteries, with a total of 73 battery systems delivering 446.9 kW of additional backup power. That’s a significant boost to local energy resilience and independence, especially valuable in a region with a mix of family homes, retirees, and small businesses relying on stable power.
Battery storage is more appealing than ever, thanks to new rebates and the buzz around Virtual Power Plants (VPPs). The Australian Federal Government’s solar batteries rebate for Cassini homeowners can cover up to 30% of the solar batteries cost, which means a typical 11.5–13.5 kWh battery could be $3,400–$4,000 cheaper to install. This incentive can halve payback periods to 3–4 years and, when combined with VPP participation, boost annual bill savings even further while making the grid more resilient for everyone. With solar batteries for solar panels now easier to access, options like Tesla, BYD, and Alpha ESS are more affordable and available locally. If you’re searching for ‘solar batteries near me’ or want to know more about solar batteries for sale, Cassini is a great place to start your journey.
