Introducing Powerwall by Tesla

November 18, 2015

Solar power is slowly gaining traction in the energy field but there has been a persisting problem with how it works. For the most part, storing the energy collected during the sunlit hours was problematic. Batteries were not efficient and cost-effective enough to undergo large scale transitions from oil and natural gas-based energy to the ‘greener’ solar power. Tesla believes that it has solved this problem by introducing the Powerwall home battery.

Powerwall is a rechargeable lithium-ion battery that mounts seamlessly on a wall and is integrated with the local grid to harness excess power and give customers the flexibility to draw energy from their own reserve. Its benefits include: 

  • 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.

Tesla’s selling price to installers is $3,500 for 10kWh and $3,000 for 7kWh. (Price excludes inverter and installation.) Deliveries are expected to begin in late 2015.
