At an event at Universal Studios in LA on Friday night, Tesla CEO Elon Musk took to the stage to announce Powerwall 2 (and the Powerpack 2 for businesses) and the Solar Roof. Powerwall 2 is obviously the successor to the original Powerwall, introduced in the summer of 2015. Solar Roof is a new product which uses photovoltaic cell-embedded textured glass tiles which look like regular roof slates from street level.The Powerwall 2 home battery pack is, again, somewhere to store all the energy you have harvested from your solar panels/roof. It is basically a large rechargeable li-ion battery that is intended to be installed in your garage ? where you park your Tesla car overnight. However, with or without an electric car that needs charging, the Powerwall also feeds its stored solar energy to your home as required.
