Solar incentives in Utah
What is actually on offer here in 2026 — the state incentive, the federal position, and the export rule, which is usually worth more than either.
The state incentive
Expired for residential. The Utah residential credit ended for systems installed in 2024 and later.
The federal position
§25D, the 30% residential credit, expired for systems placed in service after 31 December 2025 — installed, not merely purchased. §48E did not expire on that schedule, and a company owning panels on your roof under a lease or PPA can still claim it. That asymmetry, not anything specific to Utah, is the largest single change in residential solar economics. The detail, with sources.
Rate schedules and export rules
What your surplus earns is set here, and it is where two identical systems a mile apart stop being comparable.
Rocky Mountain Power — Schedule 1 + Schedule 137 net billing
Flat retail, seasonal export credit reset every March. Exports earn 40–48% of retail. Fixed charge $12.00/month.
Summer Flat $0.11.
Winter Flat $0.10.
Exports: roughly 4.9¢/kWh in summer and 4.0¢/kWh in winter, under Schedule 137.

Credits are the easy part. What decides payback is how much of your own production you use versus export, hour by hour, against the schedules above.
