Tesla Energy — Powering your home and business into the future

Elon Musk has just unveiled Tesla’s latest energy system, Tesla Energy and it is designed for homes and business use. Elon Musk teased earlier this week in a Tweet that something was coming

The home version called the Tesla Powerwall. It is a rechargeable lithium-ion battery that is intended to increase capacity for homes which already have solar panels and it will store energy and act as a backup power source. It can be installed in your garage or to an outside wall and will link into the local electricity grid. This model will charge when rates are lower and then kick in during peak times when the rates are raised. It can also then store energy that doesn’t get fully used so that in times of a blackout you will still have power.


There are two versions of the Powerwall and of course as of right now this is US only, a $3,500 10kWh (backup system) and $3,000 7kWh (daily use).


  • Load shifting — The battery can provide financial savings to its owner by charging during low rate periods when demand for electricity is lower and discharging during more expensive rate periods when electricity demand is higher
  • Increasing self-consumption of solar power generation — The battery can store surplus solar energy not used at the time it is generated and use that energy later when the sun is not shining
  • Back-up power — Assures power in the event of an outage

The business version is called the Powerpack but wont be on sale until 2016 and features a 100kWh battery block to provide on-demand power distribution and manage peak demand.

Tesla Energy also plans to extend to the Germany and Australia by the end of 2015.

Tesla as a company is exciting to say the least, and thankfully Tesla is due to bring its Supercharger network to Ireland over the next 1 to 2 years all going to plan.
