How I calculate this
I went through utility interconnection records: 5,430 home solar systems were installed within 8.8 miles of central Tucson in 2022–2024, by 31 companies with 30 or more systems each. The five most active still in business: Freedom Solar (582), Sunrun (533), Technicians For Sustainability (267), Our World Energy (241), Saguaro Solar Electric (177). Today, quotes average $2.26/W in Tucson (EnergySage, updated 2026-09-04) — about $15,820 for a 7 kW system before incentives.
