Recently, the Tesla Powerwall got worldwide attention when the company turned the power back on at a devastated Children’s Hospital in Puerto Rico.

But what is a Powerwall? How does it work? In the midst of a chaotic season of hurricanes and floods, a lot of people want to know if this is something they should consider setting up in their own homes.

Class is in session — settle in for your beginner’s guide to the almighty Tesla Powerwall, and you can decide once and for all if it’s right for your home.


What Is It?

The Tesla Powerwall is basically one big giant solar powered battery. The key thing to note here though is that you don’t hook it up when the power goes out.

Instead, the Powerwall is installed and tied into the electrical grid in your house and gradually collects solar energy, storing it up in its power cells. When the power goes out, the Powerwall automatically detects it and kicks on, powering your entire home as if nothing even happened.

What’s the Install Like?

The Tesla Powerwall isn’t some big terrifying fusebox you have to fence off from the kids and shelter from the rain — these things are TOUGH.

Built for both indoor and outdoor installation, they’re completely self contained and weatherproof, and will function between -4 and 122 degrees Fahrenheit.

They’re also scaleable, so depending on your typical power consumption and home size, you can install up to ten to ensure you have enough juice to carry you through until the miracle workers at the electric company get things sorted out.

There are zero wires exposed, no external inverters to fuss about; it’s an incredibly safe and user-friendly, self-contained system that goes in with some professional installation, and requires practically no input from you to operate and maintain.

As an added bonus, it’s even grid code compliant, so you don’t have to worry about insurance policies or getting it signed off on when you’re building a house.

How Much Energy Does It Provide?

A single Tesla Powerwall provides 13.5 kWh of energy, about enough to power a 900 square foot home with central air for up to seven days.

To get a clearer picture of how much energy your home might use, you can take their handy calculator for a spin and see how many Powerwalls are recommended for your home.


What Do They Cost?

A single Tesla Powerwall unit currently goes for $5,500, plus a $700 supporting hardware fee. This doesn’t include the cost of installation though, which can run up to $2,000, depending on your setup.

Running the cost of the unit and installation alongside what it would take from a generator to achieve the same results, it’s actually not that crazy expensive (and that’s not even accounting for gas for the generator).

Not only that, but the Tesla Powerwall is automatic, easy to use, completely silent, and 100% sun-powered. Pretty amazing if you ask me. (And a lot like their forward-thinking cars!)


Tesla Brings the Powerwall to Puerto Rico

Although the details still aren’t clear at this time, what is known is that after an exchange over Twitter between Tesla CEO Elon Musk and governor of Puerto Rico Ricardo Rosselló, a shipment of Tesla Powerwalls was sent to Puerto Rico in the hopes of restoring power to the hurricane ravaged island.

Amidst criticisms of President Trump doing nothing to help the people, social media is rallying in support around the generosity of Tesla as they attempt to get power back to the people of Puerto Rico.

Way to go, Tesla!
