In Australia, electricity retailer AGL Energy has extended its residential battery storage range to include larger systems for customers with substantial rooftop solar systems and greater levels of energy consumption.
The larger battery systems at 11.6kWh and 19.4kWh follows the launch of AGL’s 7.2kWh Powerlegato battery system, made by AU Optronics, a Taiwanese provider of optoelectronic solutions.
The new battery systems will be offered as part of the energy retailer’s Power Advantage Club – a network established by AGL, with the launch of its battery storage energy solutions.
AGL’s launch battery system is a 7.2kWh PowerLegato battery unit including inverter and control system.
According to Marc England, AGL executive general manager of New Energy: “There has been strong consumer interest in energy storage.
“AGL has spent the last few months learning from the more than 4,000 customers who signed up to our Power Advantage Club.
"These new storage products are the result of that learning and we will continue to innovate our offers to meet further customer needs.”
Growing battery storage market
According to consumer website One Step Off The Grid, solar energy solutions provider Solar Choice found that the average Sydney home with a 5kW solar system would need a battery with at least 11kWh of capacity to cover peak and shoulder demand in summer, but about 20% of electricity demand would still need to be met by the grid.
Further to this, the company found that a household with a 20kWh battery storage system would achieve 77% of energy self-sufficiency on an average day.
Solar Choice also found that interest in residential energy storage is soaring all over Australia, stating that “we … have witnessed a 30% increase in storage-related web traffic since the beginning of the year.”
England at AGL added: “The new additions to the range are suitable for larger family homes and can, for example, be located either inside or outdoors, used as back-up, and power a whole house to maximise energy savings.”
