In November 2016, our analysis shows that a Tesla Powerwall and a 5kW rooftop solar system could deliver electricity around the same price as grid power. Our latest estimate shows solar and storage is now significantly cheaper.
In late 2016 Tesla launched the Powerwall 2, halving the price of storage relative to Powerwall 1.

In a note in November 2016 we analysed the economics of one of these batteries plus 5kW of rooftop solar plus grid for back-up and exports, relative to grid-only supply for a household with north facing roof in Adelaide that consumes 4800 kWh per year.
The comparison worked out the annual bill with and without PV and battery.
