Need to know
- We rated 4 Idaho solar companies on licensing, warranties, local presence, track record and options. The top three: Big Dog Solar (3.5, Good), Idahome Energy (3.5, Good) and EGT Solar (EvenGreen Technology) (3, Average).
- Your utility sets what exported power earns. Idaho Power, which serves about 63% of Idaho homes, pays 15.6836¢ per kWh on summer evenings and about 3¢ at other times; Avista still credits kWh for kWh.
- Solar wiring must go through a company with a DOPL electrical contractor or limited electrical contractor (solar photovoltaic) license, and contractors must also hold an Idaho contractor registration.
What solar costs in Idaho
No federal credit for host-owned systems finished after December 31, 2025, and third-party PPA legality is unclear. Batteries and roof work cost extra. Compare each quote’s price per watt with these numbers.

What to check with your utility
Idaho Power
- Net billing since January 1, 2024: you pay the normal price for grid power, and power you send out earns dollar credits.
- Exports earn 15.6836¢ per kWh on summer evenings (3 to 11 p.m., Monday to Saturday, June to September), 3.3920¢ at other summer hours and 2.9019¢ from October to May.
- These prices stay until a filing due April 1, 2028. Dollar credit left at year end carries forward on your account and is paid out only if you move without starting new service.
- Systems can be up to 25 kW, and the application fee is $100.
Rocky Mountain Power (eastern Idaho)
- Exports earn 14.666¢ per kWh on-peak (3 to 11 p.m.) from June to October and 3.664¢ at other hours. From November to May: 5.597¢ on-peak, 1.228¢ off-peak.
- Wattsmart Battery pays $1,000 or $2,000 once for a new battery added to solar. Leave the program early and you repay part.
- You must own the system, up to 25 kW. The application fee is $85.
Avista (northern Idaho)
- Schedule 63 credits extra power kWh for kWh, for systems you own up to 100 kW.
- Credits still unused on March 31 each year go to Avista.
- The rule has a 1.52 MW program limit. Ask Avista in writing whether it still takes new systems.
Kootenai Electric Cooperative
- Credits extra power kWh for kWh. Banked credits do not expire but are adjusted each April.
- Net-metered homes pay a $32.50 monthly service charge and a loss charge of $0.00971 per exported kWh.
Other co-ops and city utilities
- The state regulator does not set their solar rules. Idaho Falls Power and other co-ops each have their own terms.
- Ask for the export price, any solar charge and the size limit in writing.
Check the company and its warranty
Three names can appear in one solar deal: the company that sells, the company that signs the contract and the licensed people who do the work. Check that they fit together.
- Contract company: look up its license on the Idaho DOPL electrical contractor license (Idaho Electrical Board) plus Idaho contractor registration (RCE number), both issued by the Division of Occupational and Professional Licenses. The name must match your contract.
- Electrical connection: Wiring solar into your home is electrical work: Idaho Code 54-1002 makes it unlawful to act as an electrical contractor without a DOPL electrical contractor or limited electrical contractor license, and DOPL issues the limited license in a solar photovoltaic category (https://legislature.idaho.gov/statutesrules/idstat/Title54/T54CH10/SECT54-1002/). Ask who does it.
- Warranty documents: ask for the workmanship warranty, the roof coverage terms and each equipment warranty before you sign.
Before your first sales call, read questions to ask your solar installer and how to read a solar quote.
Compare your Idaho quotes
Ask every company to quote the same basics. Then the differences you see are real.
From quote to permission to operate
Some steps overlap, and timing depends on your town, your utility and equipment supply. Ask each installer for a written schedule for your project.
Proposal and site check
The installer looks at your roof, shading and electrical panel and gives you a written proposal.
You and the installerDesign and applications
After you sign, the installer finishes the design and applies to your utility for the connection.
Installer; you sign the formsPermits and utility review
Your town or county reviews the building and electrical permits. The utility reviews the connection.
Permit office and utilityInstallation and inspection
The crew installs the system. A licensed electrician connects it, and the inspector checks the work.
Installer crew, electrician and inspectorPermission to operate
The utility approves the system and updates your meter if needed. Turn the system on only after this step.
Utility
How we rate Idaho solar companies
Each company gets up to 100 points from facts anyone can check: its own website and Idaho’s public license records, read October 14, 2026. Facts a company does not publish earn no points. No company pays for its rating, and we do not use customer star reviews.
- Licensing (30 points): an active state license, a licensed electrician and license numbers printed on its website.
- Warranty protection (35 points): workmanship warranty length, roof-penetration coverage in writing and any production guarantee.
- Local presence (15 points): an office in Idaho and Idaho named as a service area.
- Track record (10 points): years installing solar.
- Options (10 points): batteries and the number of ways to pay.
Stars: 85 points or more is 5 (Top-rated), 72 is 4.5 (Excellent), 60 is 4 (Very good), 45 is 3.5 (Good), below 45 is 3 (Average). We did not inspect installations, collect customer quotes or test customer service.
Idaho solar company FAQs
How do I check an Idaho solar installer?
Search the company on DOPL’s public license search. Look for two active records under the name on your contract: an Idaho contractor registration (RCE number) and an electrical contractor or limited electrical contractor license. DOPL also shows discipline actions. Then read the written workmanship warranty before you sign.
Does Idaho have net metering?
It depends on your utility. Idaho Power and Rocky Mountain Power use net billing: power you send out earns dollar credits, such as 15.6836 cents per kWh on Idaho Power summer evenings and about 3 cents at other times. Avista and Kootenai Electric still credit kWh for kWh.
How does the Idaho solar tax deduction work?
It lowers the income Idaho taxes. You deduct 40% of the system cost in the year it is switched on and 20% in each of the next three years, up to $5,000 a year. What you save depends on your own Idaho tax rate. It is not a tax credit.
Can I get a battery payment in Idaho?
Only from Rocky Mountain Power. Its Wattsmart Battery program pays $1,000 for a battery under 10 kW or $2,000 above 10 kW when you add a new battery to solar, plus a small yearly bill credit. Idaho Power lists no battery payment. Quotes written before July 2026 may show older amounts.
