What Idaho still offers after the federal credit ended
Every incentive on this page is verified against Idaho government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Iona systems completed in 2026 get $0 from it.
Under Idaho's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Iona homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.
If a salesperson in Iona tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Idaho's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.
The 2026 numbers
| System size | Installed price (marketplace avg) | Notes |
|---|---|---|
| 6 kW | $15,480 | Small roof / low usage |
| 8 kW | $20,640 | Typical starter system |
| 10 kW | $25,800 | Family home with AC |
| 12 kW | $30,960 | Large home / EV charging |

Idaho rules that decide your payback
| Rule | Idaho status |
|---|---|
| Export compensation (net metering) | Idaho has no statewide retail net-metering guarantee — terms are set utility by utility, and Idaho Power, the state's largest utility, now uses real-time net billing that credits exported energy at an avoided-cost-based Export Credit Rate in dollars rather than one-for-one retail kWh, per Idaho PUC Order No. 36048. |
| State incentive | Residential Alternative Energy Device Deduction (Idaho Code 63-3022C) — an income tax DEDUCTION of 40% of system cost in the year the system is placed in service and 20% per year for the next three years, capped at $5,000 in any single year |
| Sales tax on the system | Not exempt - taxed like any purchase |
| Property tax on added home value | No exclusion on record |
Idaho's incentive is a deduction, not a credit — it only reduces the income you are taxed on, so it is worth a fraction of a same-sized tax credit; and because there is no statewide net-metering law, what you are paid for exported power depends entirely on which utility serves your address.

What this means for Iona roofs
Whether solar still pays in Idaho after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Getting Iona quotes
Marketplace platforms collect bids from multiple ID installers against the same spec, which is the only clean way to compare - same roof, same size, different prices. Getting quotes is free and does not commit you to anything; prices come from the installers, never from this site.

Common questions
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
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.
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
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.
