What Solon does
SOLON Corporation is a full-service commercial and utility-scale solar and energy storage contractor headquartered in Tucson, Arizona, with a secondary office in Scottsdale. The company delivers turnkey EPC (engineering, procurement, and construction) solutions spanning solar photovoltaic systems (parking canopies, rooftop, ground mount), battery energy storage systems (BESS), and microgrid configurations for municipalities, school districts, universities, commercial enterprises, and electric utilities across the Southwest United States (Arizona, Colorado, New Mexico, Nevada, Oklahoma, Texas). With over 194 MW of cumulative installed capacity, SOLON operates a vertically integrated model covering development, in-house engineering, construction, quality control, and ongoing operations & maintenance, supplemented by a proprietary custom-built financial modeling tool that runs hundreds of thousands of optimization iterations.
Revenue is generated through three primary streams: one-time EPC contract revenue for project delivery, recurring O&M service contracts (panel cleaning, preventative/corrective maintenance, inverter repair, emergency service), and financing arrangement facilitation (PPAs, leases, loans). The Zero Cost Solar financing program is particularly targeted at tax-exempt organizations such as municipalities and schools, enabling them to purchase on-site solar at locked-in 25+ year rates without upfront capital outlay. SOLON's customer mix is heavily weighted toward municipal and educational institutional buyers, with the City of Tucson alone accounting for 69 solar projects totaling 30.6 MW between 2019-2025, including an 8.75 MW behind-the-meter project at Tucson Water's CAVSARP facility — described as the largest such installation in Arizona.
Distribution is direct via enterprise field sales, supplemented by subcontractor roles to general contractors and EPC partnerships with large developers (notably Pivot Energy in 2024 for a 4.3 MW SeaWorld San Antonio canopy). The company has been recognized by Solar Power World as the #1 Commercial EPC Solar Contractor in Arizona for multiple consecutive years (2019, 2020, 2021, 2023, 2024) and earned Solar Builder Magazine's Microgrid Project of the Year in 2023 for the Hualapai Tribe Grand Canyon West project. SOLON is privately held with no disclosed parent company, institutional backing, or funding rounds; ownership appears concentrated with founder/management, including President Brian Seibel (18 years in solar).
