22 Dec Solar Power for New Homes: Is It Worth It?

Building a new home is a journey filled with exciting decisions, from the floor plan to the color of the paint. But one of the most impactful choices you can make is whether to integrate solar power from the start.

For new construction in Utah, the answer is a resounding Yes. The long-term financial benefits—amplified by strong federal incentives and utility programs—make it one of the smartest investments for your property.

Here’s a deep dive into why solar for your new Utah home is a strategic move.

The Financial Payoff: Federal and State Incentives

While Utah’s specific state solar tax credit for solar PV has expired for new installations, the national and utility-level incentives are still incredibly powerful.

1. The Federal Residential Clean Energy Credit (ITC)

The most significant incentive for homeowners is the federal Residential Clean Energy Credit (formerly the Investment Tax Credit or ITC).

  • Credit Amount: This allows you to claim 30% of the total cost of your new solar system (including panels, installation, and associated costs) as a non-refundable credit toward your federal income tax.

  • What it Covers: It covers solar electric panels, necessary equipment, installation labor, and even battery storage technology (even if installed later).

Important Note on Timing: The 30% credit for homeowner-owned residential systems is scheduled to end after December 31, 2025. To lock in this substantial 30% savings, your system must be fully installed and operational by the end of 2025. Act quickly and plan ahead during your new home construction process to meet this deadline.

2. Utah’s Net Billing Program (Rocky Mountain Power – Schedule 137)

The way you are compensated for excess energy in Utah is through Rocky Mountain Power’s Net Billing Service (Schedule 137). This is key to your long-term savings.

Program Export Rate (Credit for sending power to the grid) Retail Rate (Cost of power from the grid) How it Works
RMP Net Billing (Sch. 137) ~4.7 to 5.6 ¢/kWh (Rate changes by season and is updated annually) ~10 ¢/kWh (Approximate cost of RMP power) You receive a credit (the export rate) for every kWh you send to the grid. Because this rate is lower than the retail rate you pay, it’s financially advantageous to self-consume as much of your solar power as possible.
  • The Strategy: This structure strongly encourages homeowners to design a system that matches their energy usage precisely. Many homeowners pair solar with a battery to store the daytime solar energy and use it in the evening, rather than selling it back to the grid for the lower export rate.

3. Wattsmart Battery Program

Rocky Mountain Power (RMP) offers incentives for adding battery storage to your solar system, which works perfectly with the Net Billing structure.

  • Rebate: RMP offers a one-time rebate for installing an approved battery system.

  • Grid Services: In exchange, RMP can briefly draw power from your battery during peak demand times (this is a utility-managed service, and they must leave you with a minimum capacity for backup). This program helps the grid while providing you with an incentive.

Long-Term Value, Efficiency, and Control

4. Higher Home Value

Utah’s real estate market is competitive. A new home with an owned solar system is a significant differentiator. Not only do solar homes sell faster, but they typically command a premium, with studies showing an increase in home value by 4% or more. This offset the upfront costs and delivers a huge return when it’s time to sell.

5. Lock in Energy Costs

Utah residents, like all Americans, are subject to utility rate increases. By generating your own power, you fix a large portion of your energy costs for the next 25+ years. This insulates you from future market volatility and provides budget certainty.

Final Verdict for New Utah Homeowners

Going solar with your new construction home is the ideal because you can lock in the 30% Federal Tax Credit by completing your system before the impending deadline.

By choosing solar, you are not just reducing your bill; you are building an independent, valuable, and future-proof home in the Beehive State.
