Idaho vs Nevada Solar Incentives: Which State Gets the Better Deal?
Side-by-side comparison of Idaho and Nevada solar incentive programs in 2026: state tax credits, net metering rules, exemptions, payback period, and projected 25-year savings.
| Metric | ID · Idaho | NV · Nevada |
|---|---|---|
| Avg Monthly Bill | $115 | $145 |
| Peak Sun Hours / Day | 5 | 6.4 ◆ |
| Avg $/Watt Installed | $2.8 | $2.75 ◆ |
| State Tax Credit | None | None |
| Net Metering | avoided-cost | modified |
| SREC Market | No | No |
| Property Tax Exempt | No | No |
| Sales Tax Exempt | No | No |
| Avg Payback (yrs) | 10.2 | 7.3 ◆ |

State Tax Credit Comparison
Idaho offers no state income tax credit. Nevada offers no state income tax credit.
Net Metering Policies
Idaho: avoided-cost rate net metering active. Nevada: modified rate net metering active.
Net metering is often the most economically significant solar policy because it determines how excess production is valued. Retail-rate states (where you receive full retail price for exported energy) have substantially better solar economics than avoided-cost or no-net-metering states.
Average 25-Year Savings
Idaho: $24,800 over 25 years (avg payback 10.2 yrs). Nevada: $41,900 over 25 years (avg payback 7.3 yrs).
Verdict: Which State Wins on Solar?
Nevada delivers stronger lifetime solar economics than Idaho due to higher solar irradiance.
