ION Solar is the largest privately-owned residential solar company in the country.

ION Solar, LLC is a solar energy design and installation firm headquartered in Provo, Utah. ION Solar was created in 2017 from the merger of two other Utah solar energy companies, Vision Solar of Provo and Zing Solar of Draper. Following this consolidation of assets, ION Solar instantly became the largest privately-owned solar energy contractor in the country.

The CEO of ION Solar is Jimmy Slemboski and its President is David Rasmussen. Slemboski is a trained physicist who founded Zing Solar in 2012, while David Rasmussen and his brother Matt co-founded Vision Solar in 2013. Including installations completed when the two companies were separate, ION Solar, Inc. has finished more than 12,000 residential solar projects. ION Solar has not been as active in the commercial sector, but it has still completed more than 50 projects for businesses of various sizes.

ION Solar is a full-service EPC (engineering, procurement and construction) solar contractor. Under the supervision of a project manager, each solar

project they accept is developed and organized by a team of ION professionals, including site evaluators, design specialists, installers, permitting experts and support personnel.

With a focus on providing premium products, ION Solar acquires its solar components from a variety of sources. Its highest-quality solar panels are manufactured by Trina Solar, while its best inverters are supplied by Enphase. Both companies manufacture their solar equipment in China.

ION Solar offers in-house financing options for their clients, in the form of 12-year loans or 20-year loans with no upfront payments required. They also install residential solar energy systems under Power Purchase Agreements, which allow clients to lease ION solar panels for 25 years.

While Vision Solar and Zing Solar concentrated primarily on the solar market in Utah, ION Solar has expanded operations into multiple states. They now have affiliated offices in seven states: Utah, Idaho, Colorado, New Mexico, Texas, Nevada and Virginia.
