In an era of rising energy costs and growing environmental awareness, Australian homeowners are increasingly looking for ways to make their properties more efficient and affordable. A new report from property data firm Cotality confirms that these upgrades are not just saving money on bills—they’re also significantly boosting property values. The report, titled “Watt’s it Worth,” reveals that homes with solar power systems command a tangible price premium, making solar a smart investment for the future.
The National Impact of Solar on Property Prices
According to the comprehensive report, which analyzed over six million homes, Australian houses with rooftop solar systems are valued, on average, 2.7% more than comparable homes without them. This equates to a national average uplift of approximately $23,100. This research highlights a clear trend: energy performance is becoming a key factor in how homes are appraised, financed, and sold. As Senior Director at Cotality, Tom Coad, notes, “homes with energy and efficiency upgrades are delivering not only long-term energy bill savings and comfort, but also measurable price premiums”.
Regional Variations Reveal a Strong Buyer Demand
While the national average is impressive, the financial benefit of solar panels varies significantly across different regions, reflecting local buyer demand for energy-saving features. The highest percentage uplift was found in the Regional Northern Territory, where a solar system can add an estimated 6.9% to a home’s value, or about $31,350.
Other notable findings include:
• Hobart: Leads the capital cities with a 5.4% uplift, translating to a dollar value increase of $30,459.
• Brisbane: Sees a 3.3% premium, adding over $30,000 to a home’s value.
• Sydney: While the percentage increase is a more modest 1.6%, the high property values mean this still equates to a significant $19,179 uplift.
• Adelaide and Perth: Experience lower dollar value increases at $14,093 and $14,939, respectively.
These figures demonstrate that buyers nationwide are recognizing and willing to pay for the immediate and ongoing benefits that solar power provides, such as reduced reliance on the grid and lower electricity bills.
Why Solar Is Reshaping the Housing Market
Solar panels are one of the most visible and widely adopted energy upgrades in Australia, making them easily recognizable to buyers and reliably measurable in valuation models. This visibility helps explain why their value is being priced into the market so consistently.
The growing adoption of solar is also changing the landscape of Australian suburbs. Nationally, 29% of houses now have rooftop solar, with coverage exceeding 40% in cities like Brisbane, Adelaide, and Perth. In some newer housing estates, solar is becoming a standard inclusion, embedding energy performance into the market from the ground up.
As Australia moves towards greater energy transparency, with more states expected to follow the ACT’s lead in mandating energy rating disclosures, the value of energy efficiency is set to become even more prominent. The “Watt’s it Worth” report signals a clear shift in how property value is perceived, suggesting a future where a home’s energy performance is “priced as prominently as postcode
