Idaho’s Solar
Report Card


To determine a grade for each state, our researchers and solar experts analyzed data on crucial solar-advancement criteria from the following sources:

We determined a rank from 1 to 10 for each state in each category. We then combined the scores with the following weights and assigned an overall grade for each state. Our goal is to encourage those considering solar for their homes to get a basic understanding of solar potential in their areas and discover the best opportunities for clean energy available.

Electricity Costs in Idaho

Residential electricity costs are on the rise across the United States, and it’s no different in Idaho. Current prices sit around $0.0098 per kWh, which is below the national average of $0.13 per kWh. Nevertheless, with few fossil fuel resources, more than three-fourths of Idaho’s electricity is generated from renewables.

Incentives & Solar Policies

Idaho rivals Florida for the amount of sunshine it receives, and residents investing in solar power may see their system paid off in just a few years. This is thanks to the state’s rebate and incentive programs, designed to encourage homeowners to invest in this renewable resource. The Governor’s Office of Energy Resources also offers low-interest loans for those looking to make a move to renewable energy. The state legislature has also made moves to support green technology. Find out more about how to save on solar in Idaho.


State Energy Loan Program

Low-interest loans are available from the Office of Energy Resources for building improvements that conserve energy. Loans carry four percent interest with five-year terms and require project analysis fees of $100 for residential loans and $250 for commercial loans.

None for residential specifically

Renewable Energy Project Bonds

According to Senate Bill 1192, the Idaho Energy Resources Authority is charged with providing financing for non-utility developers of renewable energy projects, including solar photovoltaic installations, in the state.


Rocky Mountain Power Net Metering

Although net metering is not required, all three of Idaho’s investor-owned utilities have net-metering programs. Rocky Mountain Power limits residential systems to 25 kW and limits single customers from generating more than 20 percent during peak production. Net excess generation credits are carried forward to the next month.

Avista Utilities Net Metering

Excess generation during a monthly billing period is credited to a customer’s next bill at the utility’s retail rate for a year. Each year, any remaining credits revert back to the utility with no compensation to the customer.

Idaho Power Net Metering

Residential systems must be 25 kW or smaller and larger commercial systems must be 100 kW to participate. Excess generation credits may be carried forward indefinitely until they are used or the customer discontinues service.

Solar Easements

Idaho’s solar easement provision does not create a right to sunlight, but it does allow parties to voluntarily enter into solar easement contracts to ensure exposure for a solar installation. The solar easement is attached to the property on which it was created and passes with the property title.

Residential Alternative Energy Tax Deduction

Taxpayers are allowed a state income tax deduction of 40 percent of the cost of solar energy devices used for heating or electricity generation during the year in which the system is installed and 20 percent of the cost each year for the next three years. Maximum yearly deduction is $5,000.
