Sunrun Wins the 2026 Platinum Solar Award and Best Company's Preferred Partner Award

July 16, 2026 - Pleasant Grove, Utah

Best Company is proud to announce that Sunrun has been awarded the 2026 Platinum Solar Award, one of only ten awards being handed out this year. For the third consecutive year, Sunrun has been honored with the Platinum Solar Award, complemented by its second Preferred Partner Award. Notably, Sunrun remains the sole residential energy provider to earn the Preferred Partner distinction. Sunrun is also the only solar company to receive Best Company's Preferred Partner Award, further recognition of its commitment to homeowners and to the solar and home energy industry as a whole.

If last year's award recognized Sunrun as America's leading home solar provider, this year's tells a bigger story. Over the past twelve months Sunrun has grown into something more than a solar company. It has become the country's leader in home energy independence, pairing solar with battery storage and connecting hundreds of thousands of homes to the grid in ways that were still emerging a year ago.

Underneath the growth and the awards is something simpler: customers who stay loyal and spread the word. That loyalty is what Landon Taylor, CEO of Snoball, sees every day. Snoball runs referral campaigns for Sunrun, so Landon's team hears straight from the customers Sunrun serves, and by his account they are "proud to keep sending friends their way."

Why We Selected Sunrun

Sunrun's selection for these awards stems from its continued dedication to innovation, customer satisfaction, and industry leadership. As America's largest provider of home battery storage, solar, and home-to-grid power, Sunrun has demonstrated:

• Proven Scale: Now serving more than 1.1 million customers, Sunrun's experience and reach continue to set the standard for reliability and service for homeowners nationwide.
• Storage Leadership: Sunrun reached a record storage attachment rate, meaning the vast majority of new customers now pair their solar with a battery. In 2025 the company installed close to half of all the residential battery storage capacity added in the United States, a level of market leadership few companies in any industry can claim.
• Real Energy Independence: This is more than a talking point for Sunrun's customers. In 2025 alone, Sunrun's storage customers received 3.8 million hours of backup power across more than 650,000 individual outage events. When the grid went down, Sunrun homes stayed on.
• Home-to-Grid Innovation: Through partnerships with utilities and energy leaders like PG&E, NRG, Tesla, and Vistra, Sunrun is turning neighborhoods of home batteries into distributed power plants that support the grid and create new value for the homeowners who take part.
• Flexible Financing: Sunrun's subscription plans still offer predictable monthly payments and no upfront cost, keeping clean energy and battery backup accessible to a wide range of homeowners.
• Comprehensive Support: The Sunrun Guarantee continues to back customers with industry-leading repairs, maintenance, and monitoring throughout the life of their system.
• Stability: The last few years have been hard on this industry, with several large installers going out of business and leaving customers stranded. Sunrun's financial strength, recognized this year by its addition to the Fortune 1000, was again a key factor in this award. In a market that has seen real turbulence, Sunrun is built for the long haul.
