The Gem State is rich in renewable energy. There is plenty of hydroelectric capacity, tons of wind turbines, state-wide geothermal resources and even an above-average amount of sunshine. Idaho is one of the few states in which solar power has to compete with other renewables and not just fossil fuels. So far other renewables are winning hands down, with only a paltry amount of installed solar PV capacity.

At 10.17 cents/ kWh, the electricity prices in the state are below the national average of 12.81 cents / kWh. When it comes to average electricity consumption per household, residents of this state consume 11,483 kWh per year, above the national average of 10,836 kWh.

Currently, Idaho has 4 financial incentive programs and 4 regulatory programs supporting the adoption of solar energy. Idaho also has a state income tax credit equal to 7.4% of the cost of your solar panel installation that can reduce your tax liability if you invest in solar energy for your home or business. This tax credit is capped at $1,480 but the good news is that it can be combined with the 30% federal solar tax credit.

Idaho is a grid parity state, making solar power cheaper than the residential utility rates. Especially when used in combination with the 30% federal solar tax credit, the incentives listed below can significantly reduce the cost of installation of solar panels for your home or business.

  • Average retail electricity price is from the Electric Power Monthly report of the U.S. Energy Information Administration.
  • Solar Value Index is based on the analysis performed using our own solar energy calculator, Sunmetrix Discover.
  • The estimated lifetime of solar panels is 25 years for the purposes of calculating the Levelized Cost of Electricity (LCOE).
  • State incentives list is compiled from the Database of State Incentives for Renewables and Efficiency maintained by the N.C. State University.
