Tesla Powerwall: the complete battery review

Last updated 4/20/2018

Back in 2015, automaker Tesla Motors set its sights on the home energy storage market and announced the launch of its home battery product, the Tesla Powerwall.

In the past, Tesla Motors has been praised for making high-quality electric vehicles, as well as for their ability to reimagine and successfully rebrand existing technologies. In fact, while Tesla’s automobiles revitalized the 21st-century electric vehicle market, the first electric cars were invented more than a hundred years earlier.

Tesla’s rebranding of residential-use batteries is in line with their legacy of reimagining existing products. The Tesla Powerwall may represent the first time in history that everyday homeowners are truly excited about the potential of storing energy at their home.

What is the Tesla Powerwall?

Tesla describes the Powerwall as a “rechargeable lithium ion battery with liquid thermal control.”  It is one of a few companies in the residential energy storage market that makes small-scale batteries for home energy storage. The first-generation Powerwall launched in April 2015, and an updated Powerwall 2.0 was announced in October 2016. Prior to April 2018, the price of a Powerwall 2.0 battery (not including installation costs) was $5,500. It has since increased to $5,900.

Tesla battery packs are an ideal pairing for solar panel systems, especially in the case of off-grid projects where homeowners need or want to become fully independent of their utility. A solar storage solution like the Tesla Powerwall allows you to maintain a sustained power supply during the day or night. Read on to learn more about Tesla Powerwall’s cost, technology, and warranty coverage.

How much does the Tesla Powerwall cost?

The list price for a new Tesla Powerwall 2.0 battery, which offers twice the storage capacity of the original Powerwall, is $5,900. Supporting hardware adds another $700 to the equipment costs, bringing the total to $6,600. Installation can add anywhere from $2,000 to $8,000 to the final bill.

It is important to note that the list prices you see don’t include the cost of installing your Powerwall on your property. Tesla estimates that installation will add $800 to $2,000 to your bill. However, this estimate doesn’t include the cost of electrical upgrades, taxes, permit fees, or connection charges. EnergySage users have reported installation costs that add anywhere from $5,000 to $8,000 (before any financial incentives are applied). The final number will be dependent on the specifics of your installation.
