Utah Solar Incentives (2026): Tax Credits, Net Billing & More

Federal Solar Tax Credit in 2026: What Utah Residents Should Know

The federal Residential Clean Energy Credit (Section 25D) is tied to the tax year when the installation is completed (placed in service). Under IRS guidance related to the One Big Beautiful Bill (OBBB), the residential clean energy credit is not allowed for expenditures made after December 31, 2025, and you generally can't qualify by paying in advance if installation finishes after that date.

If you installed solar in a prior eligible year and didn't use the full credit, the IRS explains that unused credit can generally be carried forward to future years (subject to your tax situation).

Because the federal rules are timing-driven, it's smart to confirm how "placed in service" applies to your project and to keep documentation organized from day one.

Utah State Solar Tax Credit: Status for 2026

Utah's Renewable Energy Systems Tax Credit (RESTC) used to help residential solar PV projects, but the Utah Office of Energy Development notes that residential solar PV systems installed in 2024 and beyond are not eligible for the state tax credit.

For commercial installations, Utah's RESTC can still matter in 2026. The state describes the commercial credit as refundable and generally calculated as 10% of eligible system cost up to $50,000 (for qualifying commercial renewable systems). The state also notes that remaining portions of the credit are scheduled to expire for systems completed and placed in service after January 1, 2028 (including commercial).

Rocky Mountain Power: Net Billing (Export Credits) in Utah

Utah does not have one single statewide net metering program that applies to every utility. For many residents, the biggest confirmation step is simply identifying who serves your address.

If you are a Rocky Mountain Power customer, the applicable solar billing framework is the company's Net Billing Service tariff (Schedule 137). Under net billing, exported energy is credited based on tariff terms rather than automatically offsetting usage at the full retail rate. The tariff also describes system size parameters and program rules, including eligibility language for customer generation under the schedule.

A helpful way to think about this in 2026: your best financial outcome usually comes from designing a system that maximizes on-site usage (and storage, if it makes sense for your home), because exported energy may be credited differently than the electricity you buy from the grid.

If you want a quick baseline before you compare quotes, start with rebates, credits, and other incentives and then map those concepts to your specific Utah utility tariff.

Municipal Utilities in Utah: Some Areas Offer Net Metering

A reminder that Utah solar customers aren't all on the same utility rules.

City of St. George: Net Metering Program

Customers on the City of St. George power system can participate in the City's Net Metering program. The City explains the program, the application path, and notes program fees and a process for handling excess energy credits.

Murray City Power: Net Metering and Solar Requirements

Murray City provides a net metering and solar information hub and notes its pilot net metering program is under revision, with policies subject to change. Murray also lists installation requirements and documentation resources for customers considering solar.

Because municipal programs can differ (fees, crediting, caps, and timelines), always confirm the latest tariff sheets and program documents with your city utility before signing a contract.

Solar Installation in Utah: How Incentives Affect Your Design Choices

Solar Installation isn't just "panels on a roof." In Utah, your incentive value is often determined by how your system performs under your utility's billing rules.

A typical Solar Installation timeline includes a site assessment, system design, permitting, utility interconnection approval, installation, inspection, and permission-to-operate. Where incentives come in is at two points: when you choose system size and equipment, and when you document costs and completion dates for tax filing purposes.

This is also where working with Solar Companies (in general terms) matters: you want quotes that clearly spell out assumptions for production, export credits, and any utility-specific requirements. Avoid proposals that only show "best case" savings without explaining how exported power is valued under your utility.

What Are Needed for Solar Installation in Utah?

When homeowners ask what are needed for solar installation, the answer usually includes a mix of home readiness, paperwork, and utility steps.

Start with roof condition and shading, because a roof that needs replacement soon can complicate financing and timelines. Next, check your electrical panel and service capacity—many homes can go solar without major upgrades, but some need panel work to meet code and interconnection requirements. Permitting is another key item: most projects require local building/electrical permits, and HOA review may apply depending on your community rules.

You should also expect an interconnection process with your utility (or city power department). This often includes an application, equipment specs, and an inspection or verification step before you can operate. Finally, keep a clean documentation folder: signed contract, itemized invoice, proof of payment, equipment spec sheets, and your permission-to-operate (or equivalent) date—these details matter when you're substantiating incentives or tax positions.

How to Evaluate Solar Companies in Utah Without Getting Burned

You don't need a "perfect" quote—you need a quote that is transparent.

Look for clear production modeling, a straightforward explanation of how exported energy is credited under your utility, and a realistic payback estimate that separates "bill savings from self-consumption" from "bill credits for exports." Ask about workmanship warranty, equipment warranty, monitoring, and who handles permitting and interconnection. If you're comparing financing, request the cash price and the financed price so you can see whether lender fees are inflating the project cost.
