Sunrun Earns Best Company’s Preferred Partner Award for Customer Service Excellence for the Second Consecutive Year

SAN FRANCISCO, July 16, 2026 (GLOBE NEWSWIRE) -- Sunrun (NASDAQ:RUN), America’s largest provider of home battery storage, solar, and home-to-grid power plants, has been awarded the exclusive 2026 Preferred Partner Award and Platinum Solar Award by BestCompany.com, a leading review platform that empowers consumers to make confident purchase decisions. According to Best Company, Sunrun’s selection for these awards was based on the company’s commitment to customer satisfaction, product innovation, stability, and industry leadership.

"The benefits of home battery storage and solar have never been stronger, especially when combined with Sunrun’s award-winning customer service. We are honored to have Best Company recognize our commitment to our customers," said Chance Allred, Sunrun’s Chief Experience and Direct Sales Officer. "Providing Americans with energy security and peace of mind requires several teams working in concert. Sunrun has written the book on how to make home energy a highly-personalized and rewarding experience."

This is the third consecutive year that Sunrun has received the Platinum Solar Award and the second consecutive year that Sunrun has received the Preferred Partner Award. Sunrun is the only home energy company to ever receive Best Company’s Preferred Partner Award.

As part of its selection process, Best Company said that Sunrun stood out because of its proven scale, customer referrals, home battery deployment, flexible financing options, commitment to sustainability, comprehensive customer support, and growing network of distributed power plants.

"We hear directly from the people Sunrun serves, and in 2026 the message is stronger than ever: their customers are proud to keep sending friends their way," said Landon Taylor, CEO of Snoball, Best Company’s review and referral platform. "A third Platinum Solar Award is what that kind of loyalty looks like."

With more than 1.1 million customers, Sunrun is the innovative market leader that pioneered home energy systems offered through no-upfront-cost subscriptions. Sunrun stands alone in the industry by owning the entire customer experience, from direct sales and installation to service and support. This vertical integration has resulted in Sunrun reaching net promoter scores achieved only by the most trusted and admired consumer brands.

"Over the past twelve months, Sunrun has grown into something more than a solar company," Best Company said. "It has become the country's leader in home energy independence, pairing battery storage with solar and connecting hundreds of thousands of homes to the grid in ways that were still emerging a year ago."

The Best Company recognition comes shortly after Sunrun was named to the Fortune 1000^® list, an annual ranking of the largest U.S. companies by revenue. Sunrun is the only home battery storage and solar installer on the Fortune list. Sunrun also recently earned four Buyer's Choice Awards from ConsumerAffairs for being best in customer service, installation experience, equipment, and value.

These accolades reflect Sunrun’s commitment to customer experience and its role as a critical resource for America’s energy grid. With the industry’s most comprehensive consumer protection program—including 24/7 system monitoring, free maintenance and repairs, and a performance guarantee—Sunrun continues to deliver products and services that help customers feel confident at every step of their energy journey.
