- Sunshine varies little across a state; electricity price, installed cost and how utilities credit exported power drive most of the difference between states.
Net metering, tax credits and incentives in 2026
Utah pays less than retail for exported solar power. Under Rocky Mountain Power export credit (Schedule 137), power you send to the grid earns about 4.5¢/kWh, against 13.2¢ for power you buy. We assume 40% of a no-battery system's output is used at home as it's produced (worth the full price) and the rest is exported, so each solar kWh is worth about 8.0¢. Using more of your solar yourself, by running appliances midday or adding a battery, raises that.
Rocky Mountain Power credits exports at 4.855¢ (June-September) and 4.033¢ (October-May) from March 2026, updated each March. Source.
There is no federal tax credit for buying home solar installed in 2026. The 30% Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so the costs and paybacks on this page include no federal credit.
Utah and local utilities may still offer rebates, performance payments, property-tax or sales-tax exemptions. Search the DSIRE incentives database for Utah and ask installers which programs they apply for you.
