Idaho Net Metering

There are 28 companies in Idaho offering electricity. Of those 28, 14 of them offer some type of net metering option for their customers, making solar panels and alternative electric sources more economically feasible. The state of Idaho has restricted state level net metering legislation.

Energy Loss

Idaho has 8 providers who report energy loss. The average energy loss amount for these suppliers is 6.30%. The US average is 2.43%, meaning Idaho ranks 47th best in the nation for energy loss efficiency.

Solar Taxes And Rebates

State governments can help encourage private consumers to consider installing solar panels by giving rebates and tax breaks to people who choose to make those installs. With over $2000 or 20% in tax credits for solar purchases, Idaho has decent options for state solar tax credits. The state offers no rebates to citizens who are purchasing solar panels. Idaho offers no property tax exemptions to homeowners who install private solar panels. Homeowners in the state do not have access to a sales tax exemption when installing private solar panels.

State Level Initiatives

Whether a consumer is able to easily find electricity options with renewable fuels is partially determined by statewide legislation. Many states require renewable fuels to make up a percentage of the fuel used for electricity generation by electricity companies in the state. These guidelines are called Renewable Portfolio Standards (RPS). Idaho does not currently have any standards set up that suppliers must adhere to. In addition, there are currently no low income solar programs to encourage low income families to install solar panels.

Learn about going solar in Idaho, find out which system size is best for you, compare local installers and see which incentives are available in your area.
