Tesla Powerwall owners offer honest advice after resident considers whole-home backup

"I have had 2 multi-hour outages since. Both occurred in the evening and lasted 4-5 hours. I had no issues during either one."

As energy prices continue to rise and the U.S. is plagued by blackouts amid intensifying storms and an aging power grid, more homeowners are considering backup solutions. That's why one homeowner took to Reddit to ask about purchasing a Tesla Powerwall 3 to pair with a solar array. 

The original poster asked for firsthand testimonies in the Tesla Solar subreddit. 

"I've been told that two Powerwalls would provide whole-house power for 12-18 hours before needing to be recharged," they explained. "I'm in eastern North Carolina where we've been lucky to have no major hurricanes since Florence in 2018 — during that storm we were without power for 5 days." 

"I'd love to hear from anyone who has the Powerwall and been in a situation where you've been without electricity for at least 24 hours," they added.

Many homeowners may already be aware of the significant savings that solar panels can provide, but fewer may realize that adding a backup battery system can further boost those savings. Essentially, homeowners can charge their batteries with solar energy and then rely on that stored power when electricity rates are at their highest or after the sun goes down. 

If this information piques your interest in taking control of your own energy generation, free tools from EnergySage can help you compare solar quotes and get quick installation estimates

With whole-home batteries, homeowners can also benefit by accessing power during blackouts.

A few commenters added their thoughts about energy storage solutions.
