Idaho Net Metering

Idaho has 13 out of 29 companies reporting that they offer net metering to residents with personal solar panels. At the state level, Idaho is known for heavily restricted net metering and feed in tariff regulations.

Energy Loss

There are 8 companies in Idaho that reported energy loss. Combined, these 8 electricity companies average an annual energy loss of 5.72% of electricity generated. With a nationwide average of 2.76%, Idaho is ranked as the 6th best state in the US.

Solar Taxes And Rebates

Encouraging private citizens to purchase private solar panels can sometimes be a challenge due to high initial costs. Governments can help by enacting rebates and tax breaks for solar panel installs. Idaho has a tax credit of either over $2000 or over 20% of the cost of solar installation. The state offers no rebates to consumers who are installing solar. Idaho offers no property tax exemptions to homeowners who purchase private solar panels, making it less attractive for citizens to do so. The state does not offer a sales tax exemption for the purchase of solar, leaving residents high and dry for this one.

State Level Initiatives

Consumers who are shopping for electricity options that are made up with electricity produced from renewable fuel sources will have better luck with the existence of statewide legislation that encourage green energy usage. Many states require renewable fuel types to make up a percentage of the fuel used for electricity production by suppliers in the state. These stipulations are known as Renewable Portfolio Standards (RPS). Idaho does not currently have any standards set up that suppliers have to follow. Also, the state does not have any sort of low income solar programs that assist with the installation of solar panels at low income households.
