|---|---|---|---|---|---|---|---|---|
| 4 kW | $10,800 | $3,240 | $7,560 | 6,424 kWh | $739 | 10.2 years | $11,283 | $17,625 |
| 6 kW | $16,200 | $4,860 | $11,340 | 9,636 kWh | $1,108 | 10.2 years | $16,924 | $26,438 |
| 8 kW | $21,600 | $6,480 | $15,120 | 12,848 kWh | $1,478 | 10.2 years | $22,566 | $35,251 |
| 10 kW | $27,000 | $8,100 | $18,900 | 16,060 kWh | $1,847 | 10.2 years | $28,207 | $44,064 |
Solar Energy in Utah: What You Need to Know
Utah has excellent sun hours — rivaling California in many areas. Rocky Mountain Power offers net metering. Low electricity rates offset the solar production advantage somewhat.
Electricity Rates in Utah
The average residential electricity rate in Utah is 11.5 cents per kWh, which is below the national average of approximately 16 cents per kWh. Lower electricity rates mean the payback period is longer, but the 25-year savings are still substantial. As electricity rates continue to rise (averaging 3% per year nationally), the value of solar ownership increases over time.
Peak Sun Hours and Solar Production
Utah averages 5.5 peak sun hours per day, which is among the highest in the nation. Abundant sunshine translates directly into higher solar energy production, making each panel more productive and accelerating your return on investment. A 6 kW system in Utah produces approximately 9,636 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
Utah Solar Incentives and Programs
Utah's state solar tax credit expired in 2021. Net metering available through Rocky Mountain Power (transitioning to export credit rate). No sales tax exemption. Property tax exemption for solar.
Incentive Summary for Utah
- Federal Tax Credit: 30% ITC (available through 2032)
- State Tax Credit: None
- Net Metering: Available
- SRECs: Not available
- Avg. Installation Cost: $2.70/watt (before incentives)

Environmental Impact of Solar in Utah
Installing a 6 kW solar system in Utah offsets approximately 8,239 pounds of CO2 per year, which is equivalent to planting 68 trees annually. Over the 25-year lifespan of your solar system, that adds up to roughly 205,975 pounds of avoided carbon emissions. Choosing solar energy is one of the most impactful steps a homeowner can take to reduce their carbon footprint and contribute to cleaner air in Utah communities.
