Commercial solar in Idaho (2026)

In Idaho, the average commercial electricity rate is about 9.53¢/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 business 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.

Businesses use the Section 48E commercial credit (≈30%, up to ~50% with adders) plus first-year bonus depreciation — together typically recovering ~45–55% of project cost. Construction-start timing matters; verify before acting.

For a typical Idaho business spending about $1,500/month on electricity, our model estimates a 134.91 kW system costing roughly $195,651 after incentives, paying back in about 10.9 years, with on the order of $254,341 in 25-year savings.

Businesses in Idaho should weigh construction-start timing for the commercial credit and confirm whether the project qualifies for the domestic-content or energy-community adders, which can lift the credit toward 50%.
