SunPower SunVault Storage Now Powers the Whole Home

Homeowners can use more electric appliances for longer during a blackout

Industry-leading, unlimited use warranty now standard for all SunVault customers

SAN JOSE, Calif., March 28, 2022 - SunPower (NASDAQ:SPWR), a leading residential solar technology and energy services provider, announced that its battery storage system, SunVault™ Storage, now provides whole-home backup, meaning customers no longer have to sacrifice essentials or comfort during an outage.

SunVault now offers double the energy as previous iterations with 26 kWh and 52 kWh configurations. Based on system size and design, SunVault customers can use backup energy during a grid outage to help keep indispensable appliances running, like refrigeration and HVAC, as well as power the things that make life easier and more comfortable like a washer/dryer, pool pump or electric vehicle charger.

As weather events like floods, hurricanes and wildfires put pressure on a weakening grid, blackouts are on the rise across the country. According to analysis by the Energy Information Administration (EIA), the length of time an average American goes without electricity doubled between 2013 and 2020. Battery storage offers control and reliability customers are looking for when it comes to powering their home.

"As power disruptions are becoming more commonplace, the demand for energy resilience and reliability is higher than ever," said Nate Coleman, chief products officer at SunPower. " With the new SunVault, we are going beyond just the essentials. Customers can have the peace of mind that even if their grid service is disrupted, their lives don't have to be."

New SunVault product features include:

• Maximum energy savings with powerful charge and discharge during peak rate times
• Larger battery capacity so customers can power more devices for longer periods of time
• Clean, minimalist aesthetic; less wall clutter than other options of the same capacity
• Battery stability for maximum safety and efficiency
• Industry-leading 10-year warranty
