Sunrun has been the dominant force in residential solar since going public in 2015 and completing its acquisition of Vivint Solar in 2020. The company's core competitive advantage is its financing infrastructure: Sunrun pioneered the modern residential solar lease model and continues to offer among the most flexible no-money-down structures in the industry, including both lease and power-purchase agreement options that shift ownership, maintenance, and performance risk to Sunrun rather than the homeowner.
For homeowners who want to own their system outright, Sunrun competes on breadth of equipment selection and geographic reach rather than price. Where Sunrun truly differentiates is in markets where local installers are thin: the company's logistics network means predictable timelines and post-installation support in states where boutique alternatives are scarce.
About Sunnova
Sunnova's differentiating proposition is its Sunnova+ service plan, which wraps solar and battery installation into a long-term service contract where Sunnova assumes responsibility for performance, maintenance, and repairs. This model appeals to homeowners who want the economic benefits of solar ownership without acting as their own facilities manager.
Because Sunnova operates through a dealer network rather than as a direct installer in most markets, experience quality depends partly on the local sub-contractor assigned to your project. The upside is geographic reach that few national companies match — including Alaska and Puerto Rico where other nationals simply do not operate.
