Tesla’s Home Battery: Price, Lifespan, Availability, Alternative

1. Price

Let’s start with the price, because it’s the main factor behind the decision of whether or not to buy a Powerwall. Tesla’s home battery, Powerwall 2, costs $5,500, which is higher than the $3,000 for the previous version. However, in exchange you get 13.5 KWh of storage, versus 6.4 KWh and an included inverter, which costs around $2,000 if bought separately. In addition, the new battery is easier to install, so there are some additional savings on installation costs. Tesla estimates that the cost of the Powerwall 2 should be around $1,000. In addition, most states offer tax incentives, which will further reduce the costs. Installation costs excluded, Tesla’s home battery is cheaper than its competitors’ products, as we shall see further on.
