Queensland households are increasing their use of solar panel systems by adding battery storage, with more than 2500 homes being approved for solar panel grants and loans.

At the current market rate, the home battery storage setups will take at least 10 years to pay off, but Energex and Energy Queensland say the systems will help pay for themselves in the long run.

According to the Queensland Household Energy Survey, one third of Queensland solar-panel owners plan to add a battery to their current solar setup within the next decade.
