Tesla Powerwall: Energy Storage for a Sustainable Home


Note: This is a guest post and does not necessarily reflect the views and opinions of AutoConverse.com.

With Tesla’s unveiling of Powerwall, a home battery that charges using electricity generated from solar panels, optimism and scrutiny come in to play at a grand scale as to whether or not this a game changer for the fossil fuel business.

Powerwall, designed to provide power to your place of residence in a way that makes you less dependent of the power grid, such as in the evening or when rates are high, also fortifies your home against power outages by providing a backup electricity supply.

Automated, compact and simple to install, Powerwall offers independence from the utility grid and the security of an emergency backup.

Scrutinized by some as overhype and nothing more than a marketing gimmick, open0minded non-haters recognize the breakthrough innovation and potential for advancement this new product has.

For a narrow-minded haters take on Powerwall, go read Tyler Darden’s pessimistic spew of Tesla and Powerwall on ZeroHedge, which really is nothing more than a haters reference to the more thoughtful and calculated breakdown of the Top 10 Facts about Tesla’s $350/kWh (DC) Powerwall battery by Catalytic Engineering.

What’s truly important to note here is that Tesla, like many mobility companies such as Honda and Mitsubishi has delivered to the world an off-shoot technology that is a bi-product of its innovations, in this case a sensible power alternative for residential use.

While evidently not a be-all-end-all invention, Powerwall arguably is changing the energy game by providing to the world a power supply that hits a niche market with pack, punch, and demand.

What is Powerwall all about?

As published by The Hindu, “Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening.”

It is a residential storage system with a lithium-ion battery. So, technically, a user can be off the electricity grid.

Powerwall comes in two sizes – a 10 kWh version for back-up power (costing $3,500) and a 7 kWh version (for $3,000). These are excluding inverter costs and installation charges.

It was launched in the US market. Even there, anyone looking to buy a system may have to wait till the middle of next year. That’s because Tesla had 38,000 pre-bookings for Powerwall, and it could struggle to meet this order book.

Tesla Powerall Sells Out

Reservations made for about $800 million in batteries

On its earnings conference call according to reports, Elon Musk mentioned that they already received 38,000 reservations for the home system and 2,500 reservations for the much bigger, commercial-scale battery systems.

Some analysts at Bloomberg did the math, and estimate that all these reservations, if people actually end up buying the Powerwalls, add up to about $800 million of revenue for Tesla.

Here’s how Bloomberg Business crunched the numbers behind the $800 million:

  • The Powerwall home batteries designed to be paired with rooftop solar systems received 38,000 reservations, according to Musk’s comments during Wednesday’s earnings call.
  • Some customers order more than one battery, with an average reservation amounting to somewhere from 1.5 to two batteries. Musk described the total demand as “more like 50,000 or 60,000” batteries in early reservations. Let’s call it 55,000 batteries.
  • The Powerwall comes in two designs sold at different prices: $3,000 and $3,500 each. Let’s split the difference: $3,250 apiece.

Total Powerwall Orders So Far: $178.8 million.

  • Musk said the company has received 2,500 reservations for the commercial-scale batteries and that the typical installation comes with “at least 10 Powerpacks.” So that’s 25,000 units totaling 2.5 million kilowatt hours.
  • Musk used Twitter last week to disclose pricing for the Powerpack at $250 per kilowatt hour.
  • Total Powerpack Orders So Far: $625 million.

Combine home and commercial, and you get $800m.


So what are your thoughts on Tesla’s Powerall? Is this a game-changer for the fossil fuel industry or just an overhyped and overrated marketing gimmick by Tesla and tree huggers?
