Panasonic is closing its solar and battery storage business

One of the biggest names in the solar industry just announced its exit (spoiler alert: It isn’t SunPower this time). On Monday, Panasonic wrote on its website that it would discontinue its solar and battery storage line, which includes its popular EverVolt solar panels and batteries. Despite the closure, the company emphasized its plans to honor all warranties and continue providing customer service and support.

“Panasonic Eco Systems North America (PESNA) has made the strategic decision to exit its solar and battery storage business line,” Betsy Sagges, a spokesperson for Panasonic, told EnergySage in a statement. “This decision is part of a broader effort to focus resources on areas where we can deliver the greatest long-term value. We remain proud of the technology… and committed to a responsible transition, including honoring warranties and continuing customer service.”

While Panasonic has faced intense competition from global players for years, the popularity of the Tesla Powerwall 3 is likely partially to blame for Panasonic’s slow plummet in the residential energy storage market. Tesla’s Powerwall 3 occupied 63% of the EnergySage Marketplace share nationwide in 2024, leaving little room for Panasonic’s EverVolt battery (though this may change amid recent anti-Musk backlash).

EnergySage’s 2025 Solar & Storage Marketplace Report shows an overall decline in Panasonic’s battery and solar Marketplace share from 2021 to 2024. The Panasonic EverVolt, once the most commonly quoted and selected solar system on the Marketplace nationwide, was no longer the most quoted solar panel in any state in 2024. According to the data, Panasonic’s solar panel Marketplace share declined from 35% to 6% in just four years, while its battery Marketplace share declined from 7% to 1% over the same period.

Panasonic was once a pioneer in solar panel manufacturing, having been in the solar business since 1975. But in 2020, the company ended its manufacturing partnership with Tesla, and in 2022, it ceased in-house production of solar panels entirely, raising concerns that it was planning to exit the solar market. 

Panasonic said the decision to end in-house manufacturing was a financial one, opting to outsource production and shift its focus instead to developing its line of home energy management products. Although Panasonic expanded its EverVolt product line and even recruited Michael Phelps as a brand ambassador, its solar market share has continued to drop.

Since ending its domestic solar manufacturing operations, Panasonic—like many other companies in the U.S. solar industry—has largely depended on solar imports. The recent Trump tariffs may have also contributed to the company’s decision to step away from solar.

Panasonic is a century-old company that likely will not disappear anytime soon, so customers can rest assured that they should still be able to rely on its customer service and warranties. Panasonic has said that all warranties will be honored for both existing and future customers who are planning to install a Panasonic residential solar system. 

Customers who have concerns about their warranties should reach out to their solar installer for help or contact Panasonic solar support for more information.
