Households Increasing Solar System Sizes for EVs and Battery Storage

Surge in Solar Interest as Households Embrace Electric Vehicles

With electricity and fuel prices on the rise, more households are keen to install solar panels or expand their existing systems, particularly as interest in home batteries and electric vehicles (EVs) grows. The latest findings from the Queensland Household Energy Survey, conducted by Ergon Energy Network, Energex, and Powerlink Queensland, reveal insights into changing energy habits among residents in the state.

The survey, which engaged 4,301 participants, illustrates how technologies that were once considered cutting-edge have now become commonplace. As cost-of-living pressures mount, these innovations are proving to be effective means of savings for families.

Electric Vehicle Ownership on the Rise

Data from the survey indicates a notable rise in electric vehicle ownership, climbing from 10 per cent in 2025 to 15 per cent in 2026. Among those who do not currently possess an EV but are looking to buy a new vehicle within the next three years, two-thirds are contemplating a purchase of an electric or hybrid model. This represents a significant increase from the previous year’s survey, which saw 58 per cent of respondents expressing similar intentions.

South-East Queensland leads the state in electric vehicle ownership, boasting a rate of 16 per cent, while the demographic aged 35–54 shows the highest ownership rates at 22 per cent. Additionally, this age group also shows a strong inclination toward considering an EV, with 71 per cent showing interest.

Steady Growth in Solar PV Systems and Battery Storage

The percentage of households owning solar photovoltaic (PV) systems has remained stable at 47 per cent, a slight rise from 46 per cent in 2025. Nevertheless, there has been a marked increase in the intent to upgrade or purchase new systems, jumping from 26 per cent to 34 per cent.

Moreover, battery storage ownership among solar PV users saw a notable rise, increasing from 21 per cent in 2025 to 35 per cent in 2026. This surge is likely linked to the boosting interest in the Australian Government’s Cheaper Home Batteries Program.

While the intention to buy battery storage has eased slightly, this trend reflects the many individuals who have already acquired battery systems in the past year.
