Tucson consistently ranks among the top 5 cities in the U.S. for solar energy production, with an average of 6.8 peak sun hours per day — more than Los Angeles, Denver, or Miami. The typical Tucson homeowner installs a 10–12 kW system at a cost of $22,000–$27,000 before incentives. Tucson is served by Tucson Electric Power (TEP), which offers one of the more favorable export rate structures in Arizona — TEP’s net metering program credits excess solar at closer to retail rates than APS or SRP customers receive. That difference meaningfully shortens payback periods and makes rooftop solar a particularly strong investment for Tucson homeowners. Combined with the 30% federal investment tax credit and Arizona’s 25% residential solar tax credit (capped at $1,000), a typical Tucson system can be cost-effective within 6–8 years. Every installer on this list holds an active Arizona ROC electrical license, verified directly against the state database.
