Utah is a middling solar market. A 12.5-year payback still beats leaving the money in a savings account over 25 years, but it is not the slam dunk the ads suggest.

How Utah compares

Utah gets more sunlight than 73% of the cities we measure, and its electricity costs more than 5% of states and provinces. Both matter, but not equally: the electricity rate usually matters more, because solar saves money by replacing power you would otherwise buy. A sunny state with cheap power often pays back slower than a cloudy state with expensive power. Why that happens →

Payback stops improving as systems grow, then gets worse. You can only save on electricity you were going to buy, so once a system covers your usage the extra panels mostly export at a lower rate.

Utah solar incentives

Every US household can claim the 30% federal residential clean energy credit, which is what the "after credit" figures above assume. On a $21,660 system that is $6,498 back. How the credit works →

State, utility and municipal incentives stack on top and change often — Utah may offer rebates, property or sales tax exemptions, or performance payments. We deliberately don't list specific state programmes here because they change several times a year and stale numbers are worse than none. The DSIRE database is the standard reference and is kept current.

Net metering is the one to actually check. It decides what your utility pays for exported power, and it affects your return far more than most rebates. Rules vary by utility, not just by state, and have been getting less generous. Ask any installer exactly which net metering tariff you would be on.
