What Is a Tesla Powerwall and What Are the Benefits?

Jun 3, 2021Battery Systems, Solar Energy

You’re sitting at your desk, so dark you can’t see your hand—a loud crack and answering rumble echo outside. 

It’s the third time this month this has happened. You almost expect it, but you weren’t quick enough to hit the save button.

All your deliberation, your hard work. The board meeting is tomorrow! But nature doesn’t care; when the grid goes down, the grid stays down. What if there was a way you could have kept typing?

There is, and it doesn’t require gas, loud noise, or having to go out into the storm to start up.

Keep reading to find out what it is and why you need one.

What Is the Tesla Powerwall?

That’s right; we’re talking about the Powerwall. 

The Powerwall is a revolutionary new battery that you can install to power your home. It works well with solar panels but can also hold energy from the grid. 

Use the stored power whenever you want it. Unlike a traditional generator, the Powerwall allows you to tap into any energy that you’ve saved, and it’s quiet and looks sleek.

Benefits of the Powerwall

Anyone can reap the benefits of this home energy storage system. If you want to reduce your carbon footprint, then the Powerwall is a great choice.

Are you looking to go entirely off the grid? Then combine this with some solar panels, and you won’t have to depend on the utility companies any longer. 

Let’s take a look at some of the critical features of this energy-saving product.

Save Money on Your Bill

One of the main attractions of this battery is the ability to help reduce your electric bill.

The Powerwall is built with energy efficiency in mind, piggybacking off your solar panels to store readily accessible electricity. This type of use of the battery system also helps reduce your carbon footprint. 

Are you looking to be more environmentally friendly? Well, the Powerwall is designed with sustainability in mind. As a Tesla product, you can rest assured that every powerwall is intended to be as efficient as possible and committed to reducing the impact on the environment.

Did you know that the U.S. Energy Information Administration predicts that the electricity price will rise by about thirty cents per kWh for the South Atlantic region? That’s the highest increase in the last four years.

The Powerwall makes that a non-issue. Coupled with solar panel installation, you won’t even notice the increase in prices, giving you some freedom to spend that hard-earned money elsewhere.

Storm Watch

Another remarkable feature of the Powerwall is its ability to communicate directly with the National Weather Service to monitor for storms, allowing the Powerwall to prioritize charging ahead of time.

If you lose power, you’re all charged up and ready to run off the Powerwall you have connected. The Powerwall provides uninterrupted energy in the event of a blackout, meaning the ice cream stays nice and frosty.

Store Excess Solar Energy

If you already have solar panels, then you know about net metering. While net metering is an effective way to reduce your bill, one of the best uses for the Powerwall is to save all that excess energy.

All that excess energy is valuable. If you store that in a battery (or multiple ones), you could cover your entire house’s electricity consumption. This is especially important in the months when the weather gets hotter, and the sun shines stronger. 

If you’re like most of us who live in the United States, you probably have an air conditioner running during the summer. 

Storing up that electricity when the sun beats down on your solar panels is a fantastic way to offset the most expensive part of electricity usage during the hottest months. 

Adaptability for All Applications

The Tesla Powerwall is an excellent system for anyone looking to make a cautious step into the renewable energy market. 

Tesla allows for adaptability with its Powerwall system, giving you the peace of mind to choose what you want to cover with what you’re willing to spend. Grab just one battery, and you can have a partial home setup, covering essential things like refrigerators, lights, and computers.

If you’re looking for whole-house coverage, the powerwall can be fitted with up to 10 batteries. This setup gives even the most ambitious power user the ability to cover all the appliances and systems they need during a prolonged blackout. 

With the sleek, eye-appealing design, you don’t have to worry about any distracting or bulky pieces of equipment mounted outside your house. Tesla made these units stackable (up to three front to back), floor mounting, or wall mounting.
