Powerwall 2: the 15 minute road test

Is Powerwall 2 right for me?

Our guide is an in-depth guide to the functionality of the Tesla Powerwall 2, with a head-to-head comparison between the Tesla solar battery and other residential solar storage systems. The guide covers:

  • Powerwall 2 functionality: what's here already, what's coming from storing excess solar to back-up and buying cheap / using peak;
  • Powerwall 2 installation: permission from the grid - how to fast track, basic schematics and of course some pictures;
  • specification of Powerwall 2 versus other comparable battery chemistries and systems;
  • economic analysis for typical and large residential properties for Powerwall 2 and competitor systems - how much can you save by installing a Tesla solar battery, or any other residential solar storage system?

In summary, has Elon Musk (the vision behind all things Tesla including the Tesla car, the Tesla solar battery and Tesla solar tiles) got it right or wrong?
