Solar panel installation in Caribou County, Idaho

For Rocky Mountain Power customers in Idaho, the Idaho Public Utilities Commission set a time-differentiated export credit rate in November 2025. It applies to customers whose systems were installed since October 2020; customers who installed before then kept legacy status. Rocky Mountain Power was directed to use the new rate until it files an update on July 1, 2028.

In Idaho, a permit is required for any electrical work. The state Division of Occupational and Professional Licenses (DOPL) issues it unless a city or county has taken over electrical inspections locally.

DOPL's current inspector list assigns a state electrical inspector to Soda Springs, Grace, and Bancroft, so electrical inspections for solar there come from the state.

Green Box Solar is fully licensed and insured for electrical and solar work in both Utah and Idaho. Wherever you are in Caribou County, we handle the permits and utility paperwork for you with the city or county office that has jurisdiction over your property.

For a home system bought with cash or financing today, your savings come from the electricity you no longer buy and from your utility's credit for the energy you send back to the grid. Your quote shows both, using your utility's current terms.
