Australians: Desperate For Battery Storage

It is due to the fact that households are not getting paid,
. . . for exports of solar electricity back into the grid.
Based on average daily household consumption of 19kWh,
. . . the most effective option is to find a way to store the energy,
. . . to put it in a box for use later in the day or the evening.
In some states in Australia, around one in 4 houses,
. . . already boast rooftop solar PV systems.
When the levellised cost of solar PV and batteries,
. . . falls below the average cost of power to the consumer,($2,000.- a year)
. . . then consumers will go off-grid.

An average household off grid would need:
. . . 7kW solar system,
. . . 35kWh of storage, and
. . . a generator.
