Installer profile
Sunrun
The evidence
Founded 2007 with a BBB business start of June 2007, Nasdaq listed, with Vivint Solar among its BBB-listed alternate names. Nineteen years in business at a scale no local installer matches: 12,800 employees and over a million subscribers. Longevity as a public company also means its financial condition is visible, which cuts both ways in this profile.

4,024 BBB complaints in three years, 1,390 closed in the last 12 months. The Connecticut AG sued Sunrun in July 2024 under CUTPA, alleging employees impersonated consumers on confirmation calls, forged signatures, and performed unpermitted work. Arizona's AG reached a consent agreement in May 2025 providing consumer restitution and repairs. Texas opened an investigation in April 2026 into allegedly deceptive savings claims after more than 100 formal complaints. Three states, three separate actions, all within three years.

More than 266,000 solar plus storage systems and 1,034,738 subscribers per its Q2 2026 SEC-filed results, with 4.6 GWh of networked storage. The volume is beyond dispute. Worth noting: Sunrun does not appear on the 2026 Solar Power World Massachusetts or national contractor lists, which are opt-in, so its MA-specific volume is not independently broken out anywhere we can find.

The only fetchable document with Massachusetts license numbers is a Sunrun contractor license PDF dated January 2020, listing HIC 178937, HIC 180120, and electrical licenses A 21136 and CS-040622. The company's current state license information page lists no numbers at all, and its Taunton BBB profile lists none. Six-year-old license numbers with no current confirmation is thin documentation for a company this size.
Sunrun publishes a 25-year maintenance and repair promise, a 90% lifetime production guarantee, a battery health guarantee, and a watertight roof warranty. Read the conditions: these apply to Subscription and Protection Plus plans, not cash purchases by default. A 25-year promise from a company whose Q2 2026 results showed $186M of negative operating cash flow, a guidance cut, and 4.46x debt to equity is a promise whose value depends on the promisor still existing in 2051. That is a materially different risk than a warranty from an employee-owned local installer, and it is why this scores as a claim.

How to read this
A D is not a claim that Sunrun will fail to install your system; over a million households subscribe and most get working solar. The D says the documented pattern of state enforcement actions and complaint volume is the worst in our set, and that the product itself, a multi-decade subscription, concentrates risk on the company's long-term solvency in a way a cash purchase from a local installer does not. If you are considering Sunrun, price the same system as a cash or loan purchase from two graded local installers first and compare the 25-year math. Our full rubric, including how our own installation business gets graded on the same scale, is on the methodology page. We are a solar installer and we partner with other solar companies. Grading is structurally separated from revenue; see disclosures.
