We have only just started 2016 but Tesla have already announced that they are now shipping the first Powerwall units to customers in the United States and Australia that made orders back in the summer of 2015. The overwhelming demand for the units has prompted Tesla to ramp up production at their brand new Gigafactory in the Nevada desert.
It won't be too long now, until we start to see the Powerwall being installed around the UK. CDS Electrical are already looking forward to the day when we start installing them for our own customers.
