Utah vs Colorado Solar Incentives: Which State Gets the Better Deal?
Side-by-side comparison of Utah and Colorado solar incentive programs in 2026: state tax credits, net metering rules, exemptions, payback period, and projected 25-year savings.
| Metric | UT · Utah | CO · Colorado |
|---|---|---|
| Avg Monthly Bill | $115 | $125 |
| Peak Sun Hours / Day | 5.5 ◆ | 5.4 |
| Avg $/Watt Installed | $2.8 ◆ | $2.85 |
| State Tax Credit | 25% / $400 ◆ | None |
| Net Metering | modified | retail |
| SREC Market | No | No |
| Property Tax Exempt | No | Yes |
| Sales Tax Exempt | No | Yes |
| Payback, pre-credit model (yrs) | 9 | 8.6 ◆ |
| 25-yr savings, pre-credit model | $28,400 | $38,600 ◆ |

State Tax Credit Comparison
Utah offers a 25% state income tax credit (capped at $400). Colorado offers no state income tax credit.
Net Metering Policies
Utah: modified rate net metering active. Colorado: retail 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
Utah: $28,400 over 25 years (avg payback 9 yrs). Colorado: $38,600 over 25 years (avg payback 8.6 yrs).
Verdict: Which State Wins on Solar?
Colorado delivers stronger lifetime solar economics than Utah due to more favorable net metering rules.
