Arizona vs Utah Solar Incentives: Which State Gets the Better Deal?
Side-by-side comparison of Arizona and Utah solar incentive programs in 2026: state tax credits, net metering rules, exemptions, payback period, and projected 25-year savings.
| Metric | AZ · Arizona | UT · Utah |
|---|---|---|
| Avg Monthly Bill | $195 | $115 |
| Peak Sun Hours / Day | 6.5 ◆ | 5.5 |
| Avg $/Watt Installed | $2.65 ◆ | $2.8 |
| State Tax Credit | 25% / $1000 | 25% / $400 |
| Net Metering | modified | modified |
| SREC Market | No | No |
| Property Tax Exempt | Yes | No |
| Sales Tax Exempt | Yes | No |
| Avg Payback (yrs) | 6.4 ◆ | 9 |
| Avg 25-Year Savings | $52,800 ◆ | $28,400 |
State Tax Credit Comparison
Arizona offers a 25% state income tax credit (capped at $1,000). Utah offers a 25% credit (capped at $400).
Net Metering Policies
Arizona: modified rate net metering active. Utah: modified rate net metering active.
Net metering is often the most economically significant solar policy because it determines how excess production is valued. Retail-rate states (where you receive full retail price for exported energy) have substantially better solar economics than avoided-cost or no-net-metering states.
Average 25-Year Savings
Arizona: $52,800 over 25 years (avg payback 6.4 yrs). Utah: $28,400 over 25 years (avg payback 9 yrs).
Verdict: Which State Wins on Solar?
Arizona edges out Utah on lifetime savings primarily due to higher solar irradiance.
