Ion Solar

What Ion Solar does

ION Solar is a privately held, full-service residential solar installer founded in 2013 and headquartered in Utah, providing end-to-end rooftop photovoltaic systems for U.S. homeowners across 14 states. Its core offering bundles system design, financing, permitting, installation, and ongoing monitoring using black-on-black solar panels paired with Enphase microinverters, with installations completed through its wholly-owned licensed electrical contractor subsidiary, ION Developer, LLC. Customers access the product via direct-to-consumer channels: free online quote forms on state-specific landing pages, phone consultations, and dedicated project coordinators who manage the full engagement through commissioning.

The company's revenue model combines hardware sales, professional installation services, and Third Party Ownership (TPO) / financing arrangements that minimize or eliminate upfront customer cost in exchange for monthly payments structured to undercut prevailing utility bills. ION Solar has completed 85,000+ residential installations and 200+ MW of installed capacity, earning an A+ Better Business Bureau rating, 4.5+ stars across 7,000+ customer reviews, and recognition as a top 5–10 U.S. residential rooftop contractor. Complementary lines include ION Home Services (roofing) and ION Earth, a charitable program that donates solar systems to nonprofits (Habitat for Humanity, Encircle, Homes For Our Troops) for every 2 MW installed.

In March 2022, ION Solar received its first disclosed institutional investment, led by Greenbelt Capital Partners with participation from Trilantic Energy Partners II North America, Blackstone Credit, and Energy Impact Partners—the capital is intended to support geographic expansion and continued growth of the residential installation platform.
