IdahoSolar Incentives 2026: Tax Credits, Rebates & Net Metering
Idaho homeowners can reduce solar installation costs by up to 30% through state and federal incentives. With average monthly bills of $115 and 5 peak sun hours per day, the average ID homeowner saves $24,800 over 25 years.
State Solar Tax Credit
Idaho does not offer a state income tax credit specifically for residential solar. Most homeowners rely on the 30% federal Residential Clean Energy Credit as the primary up-front incentive.
Net Metering in Idaho
Idaho requires investor-owned utilities to offer net metering on residential solar systems. The credit rate is the utility's avoided-cost rate (well below retail).
In practice, this means a properly sized Idaho system can drive net annual electricity costs to within tens of dollars of zero. Top utilities operating under ID net metering rules include Idaho Power, Avista.
Utility Rebate Programs
2 major utilities operate in Idaho: Idaho Power, Avista. Specific rebate availability varies year to year and is typically distributed first-come, first-served until annual budget caps are reached.
Before scheduling any installation, verify current rebate status directly with your utility — programs open and close throughout the year. Most Idaho installers will pull up-to-date rebate data during a site assessment.
Property & Sales Tax Exemptions
Idaho does not currently offer a property tax exemption for solar. The added home value from a solar installation is generally included in the next assessment cycle.
Idaho does not exempt solar equipment from sales tax, so installation invoices include standard sales tax on hardware components.
