A new survey has found people with higher incomes and better education no longer dominate demand for the domestic solar market.

The new QUT study reveals the highest uptake in solar PV systems comes from families on medium to lower incomes. 

Over the past decade the profile of Queenslanders acquiring solar PV has changed significantly.

The study has been published in the latest edition of Renewable and Sustainable Energy Reviews. 

Research Dr Jeff Sommerfeld said financial capacity, education status and home ownership had in the past been found to be important pre-requisites in the uptake of solar PV, but in reality there were a more complex system of variable factors at play.

“For the first time we have compared solar installation data since 2001 against factors including income, mortgage repayments, rent, family size, ownership, education status and number of bedrooms,” he said.

“This revealed that the current uptake of solar PV is based on a complex mix of demographic factors rather than taking for granted a person’s income, education or living in trendy suburbs.

“Despite the initial upfront investment, the vast majority of people acquiring solar are in outer suburbs that often have lower average incomes.

The results of the study showed:

  • the profile of consumers now acquiring solar PV users is vastly different from a decade ago;
  • income and education no longer define those acquiring solar;
  • home ownership remains a crucial feature of solar PV customers; and that the dwelling was most likely to be a house with three or more bedrooms occupied by a family of two or more; and
  • being aged over 55 years emerged as important features of current solar PV customers and may reflect concern about controlling electricity costs.

Dr Sommerfeld said the results of the study offered important policy implications for the introduction of emerging technology, such as the widespread introduction of battery systems.

“At the moment this technology is very new, priced out of reach for many and considered innovative,” he said.

“But just like we have seen with the solar PV uptake where innovators take the lead, early adopters quickly follow and then the wider population comes on board, this research is a signpost of what we might expect to see with the introduction of battery systems.”
