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

SunPower Unveils SunVault Industry-Leading Warranty

SunPower also announced it is now offering an industry-leading warranty for SunVault customers. All SunVault energy storage systems will come backed by a 10-year warranty, including 70% usable energy retention. This warranty update raises the standard for residential energy storage systems with no restriction on total energy throughput or the number of times customers can charge their battery.

Customers with SunPower^® solar systems can also take advantage of the company's Complete Confidence Warranty, which covers everything from panels and racking to monitoring hardware.

SunPower Launches New Monitoring App Enabling Homeowners to Manage Solar and Storage

New mySunPower™ app delivers actionable energy insights so users can minimize costs and strengthen resilience​​

February 3,2021, San Jose, CA – SunPower Corp. (NASDAQ:SPWR), a leading solar technology and energy​ services provider, today announced the new mySunPower™ app, the company's new experience for homeowners to review and manage their energy generation, consumption, and battery storage settings from a mobile device. The new mySunPower app for monitoring will be available for download for SunPower Equinox® customers on Feb. 16 on the Apple App Store and Google Play and will be available to all of SunPower's 285,000 monitoring customers by spring 2021.

Designed to integrate seamlessly with SunPower's existing homeowner platform, the mySunPower app makes it possible to optimize energy use, save money, and become less dependent on traditional energy providers in the face of rolling blackouts, natural disasters, and the impacts of climate change.

SunPower has completely rethought the monitoring experience for homeowners. Launch features include:

• Storage system controls: mySunPower users can control their battery settings from the palm of their hand. Homeowners can set their battery to minimize energy costs, lower their carbon footprint, or preserve maximum resilience in the event of unforeseen power outages.
• Live power flow: With live data, Equinox customers with production meters can view the immediate impact of their energy choices, including the effects of changing weather conditions, adjustments in battery settings, or even the use of small appliances such as a microwave in real time.
• In-app alerts: New notification features alert homeowners to important changes to their system status, connectivity, and weather conditions. Additional app features expected to be released later in 2021 include alerts for homeowners to prepare for rolling blackouts and other disruptions.

A TIPPING POINT FOR SOLAR AND STORAGE

According to data from Wood Mackenzie and the Solar Energy Industries Association (SEIA), more than 25 percent of on-site solar systems will be paired with storage by 2025. The new mySunPower app will reduce the learning curve for customers adopting solar and storage through a completely revamped interface, actionable insights based on real-time data, and live in-app updates on the system's status and connectivity. This customer-focused innovation will help facilitate the adoption of solar and storage systems, such as SunPower's SunVault™ storage, transforming North America's distributed energy grid.

"The launch of the new mySunPower app represents a major step forward for solar and storage customers," said Jake Wachman, vice president of software product and engineering. "By combining system monitoring and control in a single, easy-to-use mobile application, SunPower is changing how homeowners interact with renewable energy technology. The new mySunPower app establishes solar and storage systems firmly in the growing smart home ecosystem."

The app will integrate seamlessly with the mySunPower web portal, offering consumers one experience from purchase and installation to monitoring. For more information on the new capabilities of the mySunPower app, please visit https://us.sunpower.com/products/software/mysunpower.
