Sunrun Solar - #2 Ranked Solar Installer in Connecticut

Detailed Profile

Sunrun Inc. is the largest residential solar company in the United States, and the Rocky Hill office at 712 Brook Street serves as the company's Connecticut hub for sales, installation crews, and service operations. Publicly traded on Nasdaq under the ticker RUN and headquartered in San Francisco, Sunrun has been a BBB-accredited business since 2017 and reports more than one million customers nationwide. The company built its scale on a subscription model anchored by solar leases and power purchase agreements, which let homeowners install panels with little to no money down in exchange for predictable monthly payments and a Sunrun-owned system on the roof. That financing engine, combined with the 2020 acquisition of Vivint Solar, is what positions the company as a market leader in Connecticut and twenty other states.

On the equipment side, Sunrun's Connecticut installations commonly pair tier-one panels with Tesla Powerwall 3 battery storage and a Sunrun-branded mobile monitoring platform, all backed by what the company markets as its industry-leading equipment guarantee and the Sunrun Guarantee on workmanship and service. The Rocky Hill team handles permitting and utility interconnection with Eversource and United Illuminating, and the company's purchasing power on hardware can translate into pricing that smaller installers have a harder time matching.

Our research team has to be candid about the other side of Sunrun's Connecticut footprint. In July 2024, Connecticut Attorney General William Tong filed a lawsuit against Sunrun and two of its marketing affiliates, alleging deceptive sales practices that included forged signatures and, in at least one case, what investigators described as a forged homeowner voice recording. The state had logged seventeen complaints at the time of filing. Online review platforms surface recurring themes around long permitting timelines, communication gaps after the sale, and difficulty exiting contracts. Prospective Connecticut customers should read their agreement closely, confirm the signing party in writing, and ask pointed questions about who owns the system at year twenty and what happens at lease end.

With a composite score of 73.55 out of 100, Sunrun Solar holds the second-ranked position in Connecticut for 2026.
