What Utah pays for your exported solar power

Export compensation is the single biggest payback lever in 2026. Here is Utah's current rule in plain words, with the official source.

Under Utah's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.

Installed home solar for St. George homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.

St. George, Utah has about 106,288 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.

The honest 2026 answer for St. George: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is Utah's export compensation, covered in the net metering section.

Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.

Utah rules that decide your payback

RuleUtah status
Export compensation (net metering)Utah's retail net metering is closed to new residential customers, who instead take service under Rocky Mountain Power's Schedule 137 'Net Billing Service', in which exported energy earns a per-kWh export credit rate set and updated annually by the Utah Public Service Commission (the 2026 annual update was filed in Docket No. 26-035-T03 on January 26, 2026 and approved by tariff approval letter dated February 23, 2026).
State incentiveNo state-level incentive; utility rebates may apply
Sales tax on the systemNot exempt - taxed like any purchase
Property tax on added home valueNo exclusion on record

Utah's Renewable Energy Systems Tax Credit has fully sunset for residential solar - the credit stepped down from $2,000 (2017) to $1,600 (2018-2020), $1,200 (2021), $800 (2022) and $400 (2023), and residential solar PV systems installed in 2024 and later get nothing; the credit survives only for non-solar residential technologies (wind, geothermal, hydro, biomass) and commercial systems, and even that remainder expires for systems placed in service after January 1, 2028.

Getting St. George quotes

Same-day contracts are a red flag in this industry. Legitimate UT installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions

Should I lease, get a PPA, or buy?

Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.

Is solar still worth it without the federal credit?

It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.

Does solar raise my property taxes?

It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.

Do I need a battery with my solar?

Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.

What is net metering and why does it decide everything?

It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
