Cost of the Tesla Powerwall in 2020

As of November 2020, the total cost of installing one Tesla Powerwall battery system is $11,500. The breakdown of this cost goes into:

  • 1 Powerall battery = $7,000
  • Gateway and installation = $4,500

Gateway is Tesla’s energy management system. If you install more Powerwall battery packs, the Gateway and installation cost decreases. For example, two Powerwall batteries will reduce the cost to $4,000.

However, if you install a Tesla Powerwall with a solar panel system, you get a tax credit equal to 26% of the installation costs. Hence, your installation cost for one Powerwall will drop by $2,990, bringing the cost down to $8,510 from $11,000.

In some states that offer solar battery incentives, this amount will even be lesser since the SElf-Generation Incentive Program (SGIP) provides a $3,375 rebate for Tesla Powerwall installation.  Thus, if you combine the federal tax credit with a state or local incentive, you can get a 50% reduced cost when you install a Tesla Powerwall as your solar home battery.

Is a Tesla Powerwall Battery Worth It?

A Tesla Powerwall Battery can be worth it for your home if you live in a state that offers solar battery incentives. It will not add much to the cost if you get a solar energy system installed for your home.

You can even save more on electricity bills with a Tesla Powerwall battery because of its time-based control mode.  It can give you the most for your money with its amazing specifications and features, optimized with the proper installation.
