Idaho Rebates and Incentives Summary

Idaho

One of the more northerly states, Idaho isn’t known for a warm climate, but it does get plenty of sunshine. In fact, most of Idaho gets more sun than the national average. As such it’s a great place for photovoltaics. In fact, the state gets more sun than Florida, despite its northerly location. As such homeowners can expect a decent return on investment for going solar. 

As of October 2012, to promote the use of solar and other renewable energy as well as energy efficiency, Idaho offers a number of powerful incentives through the Governor’s Office of Energy Resources and others. It also offers tax deductions, rebates and low-interest rate loans for solar systems. Under the incentives a solar system could be paid off in a few years.

Idaho Solar Easements & Access Laws

In 2019, Idaho passed HB 158, which provides that a homeowner’s association may not limit or prohibit installation of solar panels or collectors on any property rooftop or structure within its jurisdiction.

The provisions only apply to rooftops that are owned, controlled, and maintained by the homeowner.

Idaho law also allows for solar easements. Similar to laws in other states, Idaho's solar easement provision does not create an automatic right to sunlight. Rather, the law allows parties to enter into solar easement contracts voluntarily for the purpose

Property Tax Exemption for Wind, Solar, and Geothermal Energy Producers

In 2007, Idaho enacted a bill that restructured the method of taxation for producers of wind energy from a property tax to a tax on production. The aim of this restructuring was to ease the burden on commercial wind farms in the early years of operation. In 2008, Idaho enacted further legislation to include geothermal energy producers under this method of taxation, and solar energy producers were included under legislation (H.B. 534) enacted in 2016. 

Under these policies, commercial wind, solar, and geothermal energy producers, excluding those regulated by the Idaho Public Utilities Commission, are exempt from paying
