Households Increasing Solar System Sizes for EVs and Battery Storage

Surge in Solar and Electric Vehicle Interest Amid Rising Costs

In light of climbing fuel and electricity prices, an increasing number of households are considering installing solar power systems or expanding their existing setups. This trend is particularly prominent among those interested in home battery solutions and electric vehicles (EVs).

The Queensland Household Energy Survey, conducted by local electricity providers Ergon Energy Network, Energex, and Powerlink Queensland, gathered insights from 4,301 participants regarding their energy behaviours and attitudes across the state.

Shift in Energy Technologies

What began as cutting-edge technology in 2009 has now become standard practice for many households. As people continue to grapple with cost-of-living challenges, these energy solutions are stepping up to help save money.

According to the latest findings, the percentage of households reporting ownership of an electric vehicle rose to 15 per cent in 2026, up from 10 per cent in 2025. Additionally, two-thirds of those without an EV and considering a new vehicle within the next three years are contemplating purchasing either an electric or hybrid model. This marks a substantial rise from 58 per cent in 2025.

Regional Insights on Electric Vehicle Ownership

South-East Queensland leads the state in EV ownership, boasting a rate of 16 per cent. Notably, individuals aged 35 to 54 represent the demographic with the highest ownership at 22 per cent, and an impressive 71 per cent of this age group are contemplating an EV purchase.

Meanwhile, the percentage of households with solar photovoltaic (PV) systems remained stable at 47 per cent, a slight increase from 46 per cent in 2025. Interestingly, the intent to upgrade existing systems or invest in new ones surged from 26 per cent to 34 per cent.

Growth in Battery Storage Adoption

Ownership of battery storage among solar PV owners also saw a notable jump, rising from 21 per cent in 2025 to 35 per cent in 2026, reflecting the growing interest in the Australian Government’s Cheaper Home Batteries Program.

While the eagerness to acquire battery storage has slowed a bit, this trend aligns with the number of households that invested in battery systems over the past year.
