What Sol Alliance does

Sol Alliance is a founder-led, full-service solar energy company headquartered in Brooklyn, New York, with a second office in White Plains, NY. The company operates an integrated platform spanning solar PV project development, consulting and owner's-representative services, turnkey engineering, procurement and construction (EPC), and community solar delivered through its Sol Suppliers sub-brand. Core technology centers on fixed ground-mount arrays, single-axis trackers, commercial and industrial rooftops, carport and garage canopy installations, and battery energy storage systems, with all projects backed by investment-grade performance insurance to support bankability.

The company serves four primary customer segments: landowners (leasing land or co-investing in solar farms), commercial and industrial building owners (rooftop leasing, co-investment, or direct ownership, including compliance with NYC Local Law 92/94), municipalities and community organizations (development and consulting engagements), and residential and SMB subscribers to its Sol Suppliers community solar program in the Con Edison service territory, which offers approximately 10% savings on electric bills without on-site installation.

Revenue is generated through a mix of professional services (development and consulting fees), one-time EPC construction contracts, recurring community solar subscription revenue, and ongoing land and rooftop lease payments to landowners and building owners. Distribution is split between a consultative enterprise field-sales motion managed by co-founders Stephen Owen and Jared Haines and a self-serve community solar channel via Sol Suppliers, with awareness driven through the company website, newsletter subscription, testimonials, and a referral and alliance partner network.
