In Idaho, the average residential electricity rate is about 12.55¢/kWh — below the U.S. average of roughly 17.6¢. Because a solar system's payback is driven mostly by the utility rate it offsets, Idaho's low rates make home solar a longer-term play that hinges on incentives and rising rates in 2026.
Idaho has no statewide net-metering mandate, so export compensation varies by utility. Confirm your specific utility's buyback terms before sizing a system.
The federal 30% residential tax credit (Section 25D) ended for systems installed after December 31, 2025. In 2026, home-solar value comes from offsetting your utility bill, net metering, and battery backup — not a federal credit.
For a typical Idaho home spending about $150/month on electricity, our model estimates a 10.24 kW system costing roughly $30,720 after incentives, paying back in about 17.1 years, with on the order of $14,259 in 25-year savings. These are estimates built from Idaho's real electricity rate — get a quote to confirm your numbers.
With Idaho's net-metering rules, 2026 home solar is increasingly about energy independence — pairing panels with a battery to ride through outages and shift usage — not just shaving the monthly bill.

No — the federal residential credit (Section 25D) ended for systems installed after December 31, 2025. Idaho home solar now pays through your electricity rate (about 12.55¢/kWh), net metering, and battery backup rather than a federal credit.
Idaho uses no statewide net-metering mandate. That affects how the power you export is credited and, in turn, your payback — full retail-rate crediting is most favorable, while net billing makes pairing solar with a battery more attractive.
At about 12.55¢/kWh, Idaho's residential electricity rate makes a longer-term case for solar economics in 2026. Run your address through the calculator above for a source-backed estimate of system size, net cost, and payback.
