What Solar United Neighbors does

Solar United Neighbors is a 501(c)(3) nonprofit organization (EIN: 46-2462990), founded in 2007 and headquartered in Washington, DC, that helps individuals, businesses, governments, and nonprofits adopt rooftop solar through community group-buying programs and consumer advocacy. The organization does not install solar or sell solar products; rather, it aggregates consumer demand by organizing solar co-ops of approximately 100 neighbors and larger Switch Together reverse-auction cohorts, then solicits competitive bids from vetted installers and provides vendor-neutral guidance throughout the procurement process. SUN operates across 14 states plus the District of Columbia and Puerto Rico, with state-specific teams in Arizona, Colorado, Florida, Indiana, Maryland, Minnesota, Nevada, Ohio, Pennsylvania, Texas, Virginia, West Virginia, and additional jurisdictions.

The organization's product portfolio includes four core group-buying programs (SUN Solar Co-ops, Switch Together in partnership with iChoosr, Ready Set Solar!, and volunteer-led Neighbors Co-ops), supported by a free vendor-neutral Solar Help Desk, a Community Solar subscription directory, a Plug-in Solar advocacy campaign for portable solar legislation, and the SUN Action political advocacy arm. SUN's underlying technology is operational rather than intelligence-driven: a website-driven sign-up flow, event management infrastructure, and the iChoosr-powered Switch Together reverse-auction platform. Cumulative program impact reported across available state-level sources totals approximately 5,300+ families served, ~43.5 MW of installed solar capacity, and roughly $229M in lifetime customer savings across reporting states.

The business model combines three revenue streams: (1) standard installer program fees paid by the selected contractor serving each co-op or Switch Together group, (2) individual donations and a recurring Sunshine Club monthly giving program, and (3) grants supporting nonprofit advocacy and education. Pricing is installer-driven and quote-based per installation; participation in SUN programs is free with no financial obligation, and average Switch Together auction discounts of approximately $6,958 per installation are reported. Customer segments include residential homeowners and renters (primary), SMBs, government and nonprofit organizations, rural residents and farmers, and community solar subscribers — all served through community-led, direct-to-consumer, and event-driven go-to-market motions.

Revenue model

1. Installer Program Fees: SUN charges the selected solar installer a standard fee (disclosed in group purchase terms) for serving as the chosen contractor for the solar co-op or group buying program. This fee is standard regardless of company and is used to fund SUN's operations. The individual participant contracts directly with the installer — SUN is not a party to that contract.
2. Donations and Membership: SUN accepts one-time and monthly donations from supporters. The Sunshine Club monthly giving program and general donations support the nonprofit's advocacy and educational mission.
3. Nonprofit Advocacy and Education: As a 501(c)(3) nonprofit organization (EIN: 46-2462990), Solar United Neighbors conducts advocacy, policy work, and educational programming funded through donations, grants, and program fees.

Scale indicators24 records

Broad incumbents

• EnergySage: Largest US online solar marketplace where consumers compare installer quotes and receive vendor-neutral guidance. Competes for the same 'shopper finds trusted installer' use case as SUN's Solar Help Desk and Switch Together, at greater scale and with venture backing.
• Sunrun: Largest US residential solar installer and lease/PPA originator. Overlaps with SUN on rooftop residential solar consumers but competes by selling its own offering rather than facilitating vendor-neutral procurement.
• Tesla Energy: Operates Tesla solar roof and retrofit solar plus Powerwall nationally with direct-to-consumer ordering. Competes for SUN's homeowners segment via a fully integrated product and direct sales channel.
• SunPower: Established national residential and commercial solar installer. Overlaps with SUN's mission to expand residential solar adoption through installer-direct channels rather than community-led group buying.

Direct peers

• GRID Alternatives: National 501(c)(3) nonprofit delivering no-cost residential solar to income-qualified households through workforce development. Most directly comparable to SUN on nonprofit solar access mission and installer coordination, though focused on low-income rather than open-market group buying.
• iChoosr: Group-buying platform operator that runs Switch Together alongside Solar United Neighbors in the US and similar collective purchasing programs in Europe. Directly comparable as a technology and program infrastructure partner for community solar/heat pump buying.
• Vote Solar: National 501(c)(3) advocacy organization focused on pro-solar state and federal policy. Closely comparable on the advocacy/education/regulatory side of SUN's portfolio (SUN Action), though Vote Solar does not run consumer-facing group purchasing.

Others

• Solar Energy Industries Association (SEIA): National solar trade association representing installers and manufacturers. Adjacent as the leading solar-industry advocacy body that SUN's state advocacy efforts often align with, but represents industry rather than consumers.
• Interstate Renewable Energy Council (IREC): Nonprofit focused on regulatory and workforce pathways for clean energy adoption. Adjacent to SUN's advocacy work on interconnection, net metering, and community solar rules; complements rather than competes with SUN's consumer-side mission.

Emerging players

• BrightSaver: Solar advocacy technology platform co-founded by Cora Stryker; SUN leadership (Anya Schoolman) has spoken alongside BrightSaver on plug-in solar. Comparable as an emerging player that combines consumer education with policy advocacy aimed at expanding distributed solar access.
