Your solar estimate
An estimate, not a quote: system size comes from your bill, production from NREL for your ZIP. No federal credit, rate increases, panel degradation or financing. How I calculate.
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: Freedom Solar (582), Titan Solar (546), Sunrun (533), Technicians For Sustainability (267), Our World Energy (241). Today, quotes average $2.26/W in Tucson (EnergySage, updated 2026-09-04) — about $15,820 for a 7 kW system before incentives.
I don't install solar or rank companies; these are counts from public records. Hank is our illustrated character, not a real homeowner or installer. If you request quotes, your request goes to a referral network of installers. How I calculate.
