“Watts it Worth” Cotality Report

New insights into how solar uptake and energy performance are reshaping property values and buyer behaviour in Australia

I was invited to participate in this special report from Cotality , quantifying the value of solar and energy efficiency ratings in real estate: solar panels add thousands to home values.

“These findings highlight that homes with energy and efficiency upgrades are delivering not only long-term energy bill savings and comfort, but also measurable price premiums at a time when cost-of-living concerns are top-of-mind for Australians”

The key takeaways

Homes with solar power systems are valued at around 2.7% more than comparable homes without, which equates to a national average of approximately $23,100.

Each additional estimated NatHERS star rating is linked to a median uplift of 1.3% in a home's value nationally, or roughly $10,560.

Nationally, 29% of houses have rooftop solar systems installed. Coverage exceeds 40% in cities like Perth, Adelaide and Brisbane, while Hobart, Regional Victoria and Regional Tasmania fall below 20%
