Tesla Powerwall Solar Battery Storage
Why we should have a self-powered home?
A self-powered home combines solar energy and Powerwall to independently power your home day and night. During the day, solar panels may produce more energy than your home uses. Powerwall stores that excess solar energy and makes it available on-demand, even after the sun has set. Through the Tesla app, you will have full visibility into your self-powered home.
How we generate your recommendation?
Tesla recommends the number of Powerwalls you need to power your home with 100% clean energy on a typical day when coupled with solar power. With or without solar, we also recommend the number of Powerwalls you need to ensure at least 24 hours of power during a utility grid outage.
How does Powerwall work during an outage?
Powerwall can detect an outage, disconnect from the grid, and automatically restore power to your home in a fraction of a second. You will not even notice that the power went out. Your lights and appliances will continue to run without interruption. If you have solar and Powerwall, then solar energy will continue to power your home and recharge Powerwall. Without Powerwall, solar will shut down during an outage.
We estimate how long your home will stay powered during an outage based on your indicated home size and the appliances you elect to back up, derived from national data. With solar, your Powerwall charge will deplete only when your home energy usage exceeds your solar power production. We cap our estimate at 7 days to account for the occasional cloudy day that may impact solar production.
