What Idaho pays for your exported solar power
Export compensation is the single biggest payback lever in 2026. Here is Idaho's current rule in plain words, with the official source.
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 Roberts homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Roberts, Idaho has about 583 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
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.
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.
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 |
| Home battery (optional) | $12,000-$16,000 | Backup power + self-consumption |

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.

Getting Roberts quotes
Same-day contracts are a red flag in this industry. Legitimate ID 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
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.
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.
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.
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.
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.
