Product Spotlight: Tesla Powerwall
Solar photovoltaic (PV) systems typically generate more energy than a home can use in a day. Systems without battery storage with Tesla Powerwall send excess energy back to the grid and the customer receives a credit on their bill from the power company. This is known as net metering.
With a battery storage option like Tesla Powerwall, excess energy that would normally be returned to the grid is stored for future use during evening hours or in the event of an outage. Keep in mind that solar arrays that aren’t paired with a battery solution cannot operate when the grid is down. This measure is meant to protect utility workers who are repairing transmission lines. However, with a battery storage solution, you can keep your home essentials running during an outage.
About the System
What is Tesla Powerwall?
Tesla Powerwall is a hybrid solar battery that can be used to keep your home functioning during a power outage. It’s helpful to think of Tesla Powerwall as a traditional generator, but without the noise and need for traditional fuel. During daylight hours, your solar array will charge your Tesla Powerwall system, allowing you to keep your home running for multiple days.
How many batteries do I need for my property?
Finding the right battery storage system size depends on multiple factors. It’s important to consider what home appliances or electronics you might deem essential in an outage. This could be your refrigerator, a few lights, your TV, or a sump or well pump.
The key word here is essential. Many home appliances use a lot of energy so it’s important consider only what would keep you most comfortable during an outage. For some folks, air conditioning may be essential, but keep in mind that this will increase the number of Powerwalls you may need to cover such a large load.
Today, most systems require at least two Powerwalls. Your Energy Consultant will work closely with you to determine which size system is right for you. Check out the chart below for some estimates on home appliance electricity consumption and the corresponding number of Powerwalls that are needed.
How long can Powerwall provide power to my home during an outage?
