💡 What the Data Says
The research, conducted by property data firm Cotality, analysed over 6 million property sales nationwide and found:
- Hobart saw the highest premium, up to $30,459 for homes with solar
- Brisbane followed closely, while
- Sydney and Melbourne homes saw premiums of $19,000–$24,000
- The solar premium was consistent across income levels and property types
In South Australia, where the combination of high energy prices and abundant sunshine makes solar an easy choice, this trend is continuing to accelerate.
💰 The Numbers Just Add Up
A standard 6kW rooftop solar system in Australia costs around $5,800 after government rebates, according to Solar Choice CEO Jeff Sykes. Even a 10kW system, more suited to larger homes, averages around $9,130.
With a $23,107 average value uplift, homeowners are potentially profiting $13,977–$17,307 from solar at resale, without even counting energy savings, which typically cover the cost of the system within 3–5 years.
“For many families, it’s the only home improvement that pays for itself twice! First in savings, then again when you sell,” says Chantha.
🔋 Batteries Are the Next Big Thing
While the report focused on solar, batteries are increasingly seen as the next high-value home upgrade.
Federal and SA subsidies now cover up to 50% off battery installation costs, slashing upfront prices by thousands.
SunEnergy customers can access:
- The Federal Battery Rebate (up to $372 per usable kWh)
- The South Australian VPP Rebate (up to $2,000)
- Ongoing earnings through Virtual Power Plants (VPPs) and energy trading platforms
🏡 The Rise of Energy-Efficient Homes
The Cotality study also showed that buyers are willing to pay an average of $10,560 more for each additional energy star rating under NatHERS (the Nationwide House Energy Rating Scheme).
In South Australia, where many older homes rate just one or two stars, the opportunity to retrofit for better efficiency through insulation, glazing, and renewable energy is significant.
