Why Tucson homeowners are moving now

After the January 2025 wildfires, battery storage became a priority

Tucson averages 6.5 peak sun hours per day and more than 280 sunny days per year, matching Phoenix in solar resource quality. The University of Arizona presence drives higher-than-average homeowner awareness of solar economics. TEP filed for a 14% residential rate increase with ACC approval expected late 2026, strengthening the long-term savings case for systems installed now. The TEP Energy Storage Rewards program (approximately $720/year for a typical 3 kW battery) makes Tucson one of the most battery-favorable markets in the Southwest.

Zero federal residential credit applied (Section 25D expired December 31, 2025). Figures are estimates based on market data as of 2026-06-01. Your numbers depend on your roof, your utility, and your bill.

Based on a 10 kW system at $2.69/W (EnergySage 2026, Pima County; range $2.25-2.77/W) and TEP's tiered residential rate (summer: 13.04 cents/kWh up to 500 kWh, 15.01 cents for 501-1,000 kWh, 15.73 cents above 1,000 kWh; effective 2026). Zero federal residential credit applied (Section 25D expired December 31, 2025). TEP's RCP export rate of approximately $0.0570/kWh (2024-2025 confirmed; 2025-2026 rate pending) means savings come primarily from onsite self-consumption. Arizona's 25% state income tax credit (capped at $1,000) reduces net cost to approximately $25,900 in year one; excess carries forward. Adding a qualifying battery (TEP Energy Storage Rewards: approximately $720/year) improves overall economics and makes battery pairing especially attractive in Tucson.

Tucson solar questions

What Tucson homeowners ask

City-specific answers. Every number references your utility and your permit office.

How good is Tucson's solar resource?
Tucson averages 6.5 peak sun hours per day and more than 280 sunny days per year - matching Tucson with the best solar resource of any major Arizona city in our research. A 10 kW system in Tucson produces significantly more annual power than the same system installed in most U.S. cities north of the Sunbelt.

What is TEP's current solar export rate?
TEP uses net billing with a Resource Comparison Proxy (RCP) rate. The confirmed rate for October 2024 through September 2025 was approximately $0.0570/kWh. The 2025-2026 rate was pending Arizona Corporation Commission approval as of June 2026. The rate locks in for 10 years from your interconnection date. Verify the current RCP rate at tep.com/rcp before signing a contract.

What is TEP's Energy Storage Rewards program?
TEP pays qualifying residential battery owners approximately $120/kW (averaged over all control events per season) for allowing TEP to dispatch the battery during peak demand. A typical 3 kW battery earns approximately $360 per season, or roughly $720 per year. Eligible platforms include Enphase, Tesla, and compatible systems. Enrollment contact is tep-battery@energyhub.com. Verify current program parameters at tep.com/energy-storage-rewards before purchasing.

Is there a federal solar tax credit in 2026?
No. The Section 25D residential credit expired December 31, 2025 under H.R. 1. Arizona's residential incentives are the 25% state income tax credit (capped at $1,000/year with carryforward), the sales tax exemption on solar equipment, the permanent property tax exemption on added home value, and the TEP Energy Storage Rewards program for battery owners.

How fast is solar permitting in Tucson?
The City of Tucson and Pima County both accept SolarAPP+ for instant residential PV permit issuance at a base fee of $94 plus a platform processing fee. Pima County Solar One Stop provides single-counter service for unincorporated areas. Note that SolarAPP+ has eligibility restrictions for some environmental or flood zone designations; verify your property's eligibility before submittal. AZ HB2301 (January 1, 2026) requires all AHJs to respond within 2 business days.
