Why State Incentives Matter Now
Rocky Mountain Power (RMP) offers net metering across Utah for residential systems up to 25 kW. When your panels produce more than you use, excess electricity flows back to the grid — and RMP credits you.
- 1:1 kilowatt-hour credit during most of the year
- Annual true-up in March — unused credits are purchased at the avoided-cost (wholesale) rate
- 25 kW max for residential net metering
- Time-of-Use (TOU) billing can increase summer credits when electricity prices peak
🔋 Rocky Mountain Power Programs
RMP offers incentive programs that make upgrading even more valuable:
- Wattsmart Residential Incentives: Rebates on efficient appliances and home electrification
- Home Energy Reports: Compare your usage with similar homes to find savings opportunities
- Solar Connect: Streamlined interconnection process for new solar installations
🤝 Community Solar (Wattsmart Community Solar)
For Utahns who can't install panels (renters, shaded roofs), RMP's community solar program lets you subscribe to a local solar farm. You receive bill credits proportional to your subscription, typically saving 5-15% on electricity costs.
🏠 Property Tax Exemption
Utah provides a 100% property tax exemption for residential solar energy systems. The added value from your solar installation does not increase your property taxes.
⚠️ State Tax Credit: Expired
Utah previously offered a state tax credit for solar, but it expired in 2017. However, the 30% credit (valued at up to $7,500+) more than makes up for it, and Utah's sunshine means faster payback regardless.
